Pros: Awesome system. Keeps my CPU cool and says it can support multiple waterblocks, although I only have the CPU block supplied (Danger Den IONE on the way for my eVga GT!). I have never installed a watercooling system before and this kit was pretty straightforward with no case modding necessary.
Cons: Well here we go, like I said this was the first time I've installed a water cooling system, so I really didn't know what I was doing. I followed everything by the book, even down to letting it run for an hour unnattached to the mobo to check for leaks. Everything looked good (I even put white paper underneath the radiator and pump to show drips better if it was leaking!). About an hour after I installed the kit, and right in the middle of installing windows, my monitor shuts off. After messing around with the external connections and restarting my comp for about an hour I decided it was time to look inside the case for error's. Then I noticed it. A huge puddle of green liquid on top of my brand new eVga GT! All my connections were right and leak free. However, the manufacturer had failed to securely fasten the block to it's attached pump and caused the O-ring to have a poor seal.
Overall Review: The good news: I had accidently ordered 2 of these bad boys from newegg. I still hadn't returned the extra so I took the pump from it and everything worked fine. After removing the old pump I could plug one of the barbs with my finger and blow into the other, and i could here air whizzing between the copper block and the plastic pump! The bad news: My poor eVga still isn't working correctly. The even worse: The giant puddle of PC antifreeze soaked and removed a sticker on my GPU that says: "warranty void if removed".
Designed with room to expand, the capacity to cool additional devices appears to be limited by the HX’s stock fans.
- Swiftech’s HX combines the installation ease and leak-free operation of a closed-loop cooler, plus the expandability of an open loop, without requiring an open-loop system's reservoir. A shorter-than-average length also eases installation in tight cases.
- As-delivered cooling capacity is a little lower than our largest "Big Air" CPU cooler.
Opening Up Closed Loop Cooling
While ease-of-installation tops the list of why closed loop builders out-sell open loops, reduced maintenance is also a big factor for most buyers. Only the most die hard liquid cooling enthusiast could enjoy constantly checking coolant levels, topping them up, and flushing out algae growth when their coolant isn’t “toxic enough”. Regular users, including part-time enthusiasts, are better off with a system that doesn’t have evaporation holes or air exposure.
On the other hand, there’s not much a person can actually do with a closed loop cooler other than attach it to a single component. OK, we’ve seen a few closed loop GPU/CPU combo coolers, but those were all factory-connected to a graphics card. If you wanted the option of configuring your own CPU and GPU cooling combo, you formerly needed to build an open loop system. Swiftech hopes to change all that with a closed-loop cooler that builders can open.

Swiftech H Liquid Cooling System
The H CPU cooler is an All-In-One (AIO) liquid cooling system focused on low to inaudible operating noise and thermal performance that truly rivals that of custom kits. The product is compatible with most cases supporting dual mm or larger radiators. It comes factory pre-filled, completely plug-and-play for installation, and is maintenance-free during its 3 year warranty period.
The H is the result of 3 years of research and development, and it was designed to bridge the gap between entry level All-In-One and custom-built DIY liquid cooling systems. It differentiates itself from other AIO's by its ability to support additional liquid cooled components such as graphics cards, chipset, and/or additional radiator(s) just like a custom-built system.
Both the pump and the fans are PWM compliant devices, allowing the H to be recognized and speed-controlled by the motherboard depending on CPU temperature like any standard CPU cooler. As a bonus, the system includes a PWM splitter allowing connection of up to 8 PWM devices which can then be controlled as one by the motherboard.

We should probably start by addressing one of the most obvious compromises of this design. Part of what makes the Swiftech HX3 unique is that it functionally combines all the key components of an open loop – aside from the actual waterblock – all in one unit. The radiator, the pump, a miniature reservoir, and the tubing is all attached to the bottom of the radiator, creating an area of airflow impedance while solving other problems. This allows Swiftech to build a semi-expandable design while still checking the CLC boxes, and critically allows Swiftech to dodge Asetek’s patent that allows the company to blockade other manufacturers from building pump-in-block solutions. Since this is the most obvious place to put the pump, and because the patent has been successfully defended in court rulings, companies more wary of lawsuits and still desiring to sell in the US have had to resort to unique solutions. EK built its Phoenix line, which also attaches the pump to the radiator, but resultingly encounters fitment issues in cases. Top-mounting the Phoenix line isn’t as universally compatible as the average CoolIT or Asetek CLC, and price is also higher due to complexity of design and lower volume production. Deepcool’s Captain series also attempts to bypass this patent, but manages to keep the pump in the block area. As we showed in our factory tour of Deepcool, this solution uses a multi-chamber design so that, technically speaking, the pump isn’t actually attached to the block, but is rather mounted independently in a separate chamber adjacent to said block. It’s a clever bypass, but still has some trade-offs – mostly looks and additional hardware, extra tubing – but it also resolves radiator fitment concerns.
Swiftech’s design has a unique compromise that most other workarounds don’t face, and that’s the airflow impedance through the radiator caused by trying to leverage the additional area for more fan mounting. Swiftech allows for an extra fan to be mounted by orienting the pump-and-res vertically along the radiator, with some surface area lost to blockages.
The total radiator mounting area – not surface area on the whole, as that’d be calculated against the fins, but the exposed face on one axis – is approximately mm by mm long. For reference, the upper portion of the blockage – the section that sees the top half of the reservoir and the entire pump chamber – is about mm x mm. The lower blockage is about mm x mm. The total blockage area is about % obstruction to airflow. The upper portion is much more severe, as the pump disallows any airflow through the radiator. The lower portion is not flush with the radiator, and so air can still flow through. Swiftech will be at a disadvantage in a like-for-like scenario where no blockage is present, but it may be able to make-up for this deficit elsewhere, as we’ll see today.
Swiftech has also found other ways to heavily differentiate its CPU cooler, like the standardized clear, open loop tubing used for routing the radiator to the block. Swiftech pre-fills this with a Mayhems Pastel White coolant, a stark departure from the usually blacked-out tubing of CLCs, and further includes coolant dyes in red, green, and blue for loop color customization.
Our only problem with this is a concern of aging. Coolants with color tend to gunk-up with age, and after usage cycling our provided review unit, we eventually saw the coolant and distilled water separating within the loop. The coolant falls-out when the cooler is left unused periodically, although turning the loop back on gets it cycling again. We took photos of the separation of color to help demonstrate this. What we don’t know is the endurance of this coolant: Over time, in theory, the coolant will begin to gunk-up and lose some of that white coloration. It’s always easier to add than subtract, and so we’d prefer if Swiftech sold this unit stock with straight distilled water and a biocide, or maybe just propylene glycol, although propylene glycol tends to end-up non-clear, like green or pink. Distilled water and biocide would work and more-or-less guarantee perpetual life until some other failure. If the end-user wanted a colorful loop, they could then add dyes or purchase the Pastel coolant separately. That said, we still want to commend Swiftech for coming up with a unique point of differentiation, though we think it could maybe be executed in a way that reduces concern of gunking-up fluids.
Each fan is plain overall, but includes 18 LEDs in a ring encircling the fan hub. The LEDs are diffused through plastic, yet remain individually visible to an onlooker. This is a mark of simpler, lower cost RGB LEDs, and they don’t particularly hit the RGB LED mark with any finesse. Cooling will be tested in the next section. Each fan is also the beginning of the cable management nightmare that is the Swiftech mm cooler. For all its unique upsides, the cooler feels overall unrefined in the minor-yet-important quality-of-life features, like cable management and simplicity. Each fan has, obviously, a fan cable, but also a splitter cable that diverges into one male and one female LED header, used to daisy-chain fans together. With functionally three cables per fan, we’re up to 9 already (or 6 if counting the splitter as 1 cable), plus SATA power for the pump, a pump tachometer 4-pin header, an LED cable off of the block, and an optional fan-and-LED hub that requires one more SATA power and motherboard connection. The LED implementation simply isn’t worth having to deal with this many cables, and a modular solution or different solution altogether should be worked-out for future iterations.
One thing we do greatly appreciate about Swiftech’s approach is a heavier focus on customer service. Swiftech is a smaller company, and we can identify with the desire to let all customers know that they can always reach-out for help. The cooler includes a card with the support phone number and email plainly listed, making it easy for customers to get quick help. This is a step far beyond the bigger brands, who use ticketing systems and email threads to get slow answers to easy questions. We also liked the quality assurance checklist that Swiftech includes for customers: The QC list checks off for mounting hardware, radiator assembly and fasteners, a 15 PSI leak test for some reassurance, pump flow and circulation, radiator visual inspection, waterblock inspection, and overall package content. This is all done in the California office in the US and is marked by technicians
We’d like to see the manual instructions improved, though. Using words instead of just pictures would help significantly in clarifying some things, especially with how similar the cables can look to a less-trained user. Swiftech gets the highest marks from us on making it easy to reach customer service. That’s important and often lost by bigger companies that build around marking tickets resolved rather than ensuring customers are well accounted for.
CPU Cooler Test Methodology
CPU cooler testing is conducted using the bench defined below. We use a bench that is more carefully crafted for noise performance, opting for a passively cooled PSU and 23% RPM Ti blower fan for very low system noise.
We strongly believe that our thermal testing methodology is among the best on this side of the tech-media industry. We've validated our testing methodology with thermal chambers and have proven near-perfect accuracy of results.
Conducting thermal tests requires careful measurement of temperatures in the surrounding environment. We control for ambient by constantly measuring temperatures with K-Type thermocouples and infrared readers. Two K-Type thermocouples are deployed around the test bench: One (T1) above the bench, out of airflow channels, and one (T2) approximately " in front of the cooler's intake fan. These two data points are averaged in a spreadsheet, creating a T3 value that is subtracted second-to-second from our AIDA64 logging of the CPU cores.
All six CPU cores are totaled and averaged second-to-second. The delta value is created by subtracting corresponding ambient readings (T3) from the average CPU core temperature. We then produce charts using a Delta T(emperature) over Ambient value. AIDA64 is used for logging thermals of silicon components, including the CPU and GPU diodes. We additionally log core utilization and frequencies to ensure all components are firing as expected. Voltage levels are measured in addition to fan speeds, frequencies, and thermals.
The cores are kept locked to GHz (x38 multiplier). VCore voltage is locked to v for the CPU. C-States are disabled, as is all other power saving. The frequency is locked without any interference from boost or throttle functions. This is to ensure that the CPU does not undergo any unexpected/uncontrollable power saving or boost states during testing, and ensures that the test platform remains identical from one device to the next.
Fan speeds are manually controlled unless otherwise defined. For liquid coolers, pumps are set to % speed unless otherwise defined.
No open bench fans are used for these CPU cooler tests. Only fans which are provided with the cooler are used.
We use a multi-diode thermocouple reader to log ambient actively. This ambient measurement is used to monitor fluctuations and is subtracted from absolute GPU diode readings to produce a delta value. For these tests, we configured the thermocouple reader's logging interval to 1s, matching the logging interval of GPU-Z and AIDA Data is calculated using a custom, in-house spreadsheet and software solution.
Our test starts with a s idle period to gauge non-gaming performance. A script automatically triggers the beginning of a CPU-intensive benchmark running Prime95 LFFTs. Because we use an in-house script, we are able to perfectly execute and align our tests between passes.
Swiftech HX3 Benchmark: Noise-Normalized Thermals
Noise-normalized thermals are up first. As we’ve explained in the past, this allows us to better normalize for cooler positioning by eliminating the ability for chart-topping simply via highest noise levels. We normalize for 40dBA on these charts, but note that two coolers – the mm Cooler Master prototype and the Corsair Hi Pro – couldn’t reach 40dBA due to their quieter fans, and so these two sit disadvantaged from the others. That said, they’re also not really part of the core comparison. Separately, we’ve also now added the radiator size at the front of each listing, a response to a comment in our last review requesting the change. Thanks for the idea – we think it helps a lot with legibility. The Swiftech HX3 ends up at RPM on all 3 fans when configured to 40dBA, allowing the pump to run at full speed. The Swiftech HX3 ranks at degrees Celsius over ambient, which puts it roughly within error of the EVGA CLC also at 40dBA. This performance delta can partly by explained by run-to-run variance, but more heavily can be explained by the largely blocked-off section of radiator that reduces flow for the third fan. We’ll look at linear feet per minute flow in a moment. EK’s somewhat similar MLC Phoenix still manages top performance thanks to the limited airflow impedance and combination of pump and fans.
The Swiftech cooler ends up roughly equivalent with the Corsair Hi CLC, another mm solution, and the Kraken X72 at 40dBA, also a mm solution. For the most part, the mm coolers are all within error of each other: In this one cluster, we have the Swiftech HX3, the Corsair Hi, the Kraken X72, the Celsius S36, and the EVGA CLC , all of which are mm coolers. For the most part, if disregarding peak fan RPM and normalizing for a more reasonable noise, you could just choose whichever has the better price or the better look for your build. The Swiftech HX3 doesn’t do anything to amaze in this department, but also isn’t disappointing. It’s hard to improve thermal performance of liquid coolers, and so the bigger points of differentiation end up in the installation, style, cable management, price, and case compatibility.
Measuring with an anemometer is always extremely sensitive to exact placement and positioning, much like a dB meter is. This is just a quick spot-check. We position the anemometer along a vertical support to keep its horizontal distance from the cooler the same, about ” back from the pump-res, then took spot measurements and averaged them for each location. We measured airflow in the center of the cooler as highest, averaging about linear feet per minute through the radiator at the distance measured. This was at % speed. Biased toward the top of the cooler, opposite the pump-res mount, we measured about LPM. Biased toward the bottom, directly behind the bottom fan and pump-res mount, we measured a sharp drop to about LPM, or a reduction of about % -- conveniently about the same as our radiator area coverage by the pump-res combo. Measuring directly behind the reservoir, which isn’t flush with the cooler and allows some air to get around it, we spotted LPM at about 70, clearly obstructed.
Swiftech HX3 Benchmark: Max Fan Speeds
If you’re the type who only cares about maximum fan speed, noise be damned, here’s the chart for that. The Swiftech H unit, totally maxed-out, only slightly climbs in RPM and ends up within error of its previous noise-normalized result. The result places Swiftech at around the HiV2 with its fan speeds maxed-out, which manages a higher noise level than Swiftech, and similar to the X72 with % fan speeds and a silent pump.
Swiftech HX3 Benchmark: Noise Levels
Looking at noise levels, maximum fan speed on the Swiftech cooler results in roughly a dBA reading in our standardized test bench. That’s why the cooler doesn’t chart-top for the max fan speeds listing – it’s just not focused on raw throughput, unlike EVGA’s CLC and its dBA of jet engine intake when maxed. The HiV2 at RPM, referencing the previous comparison, ranks at dBA. Although the two were matched in flat-out fan speed testing, the HiV2 ends up more than 2x louder in perceivable noise to the human ear – and again, we’re not talking acoustic power, but perceptible noise.
Our biggest concern with the HX3 is whether it’ll gunk-up with age. We won’t know until it’s been around for longer than the average review cycle, unfortunately, so it’s tough to say if (or how quickly) this will gunk-up. Most colorful coolants do inevitably fill the blocks with fall-out from the coloration, so we’d like to see Swiftech perhaps move toward a simple distilled water baseline, with the users given the option of adding their own color later.
As far as performance, it’s about equal with the other mm closed-loop liquid coolers when noise-normalized. The fans aren’t particularly impressive, but aren’t bad. We think that Swiftech could improve on the fan/RGB implementation, as the current one becomes overwhelming for cable management.
Thermally, the cooler is fine. Swiftech gets huge points for its consumer-focused support policies, something that larger competitors have lost to the annuls of time. The bigger cooler manufacturers are more focused on getting customers in-and-out of the ticketing system, not actually fixing the problems, and that’s something we often see resolved with the smaller companies who still have owners close to the customer. There aren’t as many layers of separation between the top of Swiftech and the customer. We don’t see any particularly compelling argument from purely a thermal standpoint to buy the HX3, but the customer support angle is valuable. It’s also expandable into what can become “baby’s first open loop,” if desirable, so that’s also valuable.

Cooling swiftech liquid
Following the release of their HX and HX CPU liquid cooling kits, Swiftech has now a single mm variant of the series. Thanks to the reservoir and pump built into the radiator, there is no need for an endtank like tradiational rads have and so the radiator itself occupies the same dimensions as the mm fan itself ( x , thickness of course still a factor). This will help with watercooling in cases where fan spacing has been considered but not the extra length or breadth that a radiator usually occupies. The kit is available for purchase from their website at an MSRP of $ in the USA. See below for full press release:
Long Beach, Calif., November 11th, , Pacific Standard Time Rouchon Industries Inc., dba Swiftech® (OTC Pink Current: RCHN) today announced the release of the HX all-in-one CPU liquid cooling kit.
Following in the footsteps of the award winning H and HX CPU coolers, the patent pending HX all-in-one liquid cooling system is a scaled-down version designed to fit space constrained systems. Despite its smaller size, featuring a mm radiator, the product remains entirely focused on low to inaudible operating noise with extreme thermal performance, and is engineered to appeal to the broadest possible spectrum of performance oriented users ranging from casual to hard-core enthusiasts. For casual users, the kit is shipped factory pre-filled, ready for plug-and-play installation, and it is maintenance free during its three warranty period. For enthusiast users, the kit can be fully customized thanks to easily replaceable tubing and fittings, and its powerful pump can easily support additional components such as graphics cards and/or extra radiator(s).
Gabriel Rouchon, Swiftech’s chairman and CEO declared: “The release of the HX closes the first chapter of a promise we made at CES to offer a complete range of low noise, high performance, enthusiast grade, all-in-one CPU Coolers based on our Patent Pending Technology. It took us a little longer than anticipated, but the overwhelming market response and total customer satisfaction we are seeing now prove that it was worth the wait.”
