Sure, sheer computational power makes a great impact in your PC’s performance, but so does effective cooling. Yes, greater cooling is the key to better desktop gaming, and at CES 2022, HP’s unusual new take on classic closed-loop cooling caught our eye.
HP’s clever idea might not dazzle you as much as CyberPower PC’s wacky “breathing” PC casing, but it’s a far more practical design. HP has already patented a Cryro Chamber, which is a case rejiggering that efficiently boosts CPU cooling by relocating the liquid cooler out of the heated interior of the PC.

Most gaming PCs today employ all-in-one closed-loop coolers, which are essentially scaled-down automobile radiators for the uninitiated. They extract heat from the CPU and expel waste heat from the computer via a radiator. The issue lies with the overall design of cases: The radiator is normally located in the rear, top, or front of the system in a rectangular box.
Heat is transferred from the CPU to the radiator through a water block and hoses in systems where the cooler is mounted on top or in the rear. The radiator, on the other hand, is still installed within the PC, thus even if the heat is dissipated via it, the radiator is “cooled” first by air heated by the graphics card, voltage control modules, and other components inside the PC.
HP’s smaller Omen 25L desktop, which employs the standard arrangement used in the vast majority of PCs, is an example of this. Although the Omen 25L appears to have been thermally built to lessen hot air traveling through the top-mounted radiator, it will always be warmer than cold air coming in from outside.

HP overcomes the problem of feeding the radiator hot air by pushing it up and out of the PC case itself with the new Cryo Chamber, which is utilized in the bigger Omen 45L desktop introduced at CES. Liquid cooling from the outside isn’t a novel concept. In the early days of custom liquid cooling, radiators were mounted outside the case and connected to an input and output. Internally placed radiators have almost removed exterior radiator systems today, at the cost of consuming interior hot air.
Until now, with the Cryo Chamber in the Omen 45L seen below. The water block and pipes from the closed-loop cooler flow into the Cryo Chamber located above it. This approach involves front-mounted fans sucking in outside air and exhausting it out the back, cooling the radiator. There is no cross contamination with the hot air created in the main PC chamber since the gap isn’t vented on the inside.

You might be perplexed by the image above, but it’s from an HP presentation demonstrating the Cryo Chamber. Unlike traditional PCs, cool air is drawn in from the front and vented from the rear. Meanwhile, thermal energy is transferred to the radiator via the liquid in the hoses, which is supplied with the cleanest, purest air via a tube that runs through the heart of the case. Negative Nates may claim that the air temperatures don’t matter, but HP claims that its testing demonstrates the Omen 45L’s Cryo Chamber gives a 6 degree Celsius temperature decrease at full load with a room temperature of 25 degrees Celsius. HP’s testing, on the other hand, were done using a Cooler Master 120mm CLC, which was most likely placed inside the chassis, similar to the smaller Omen 25L pictured. The difference could be a little closer if a bigger 240mm cooler is installed in front.

HP, on the other hand, does not just isolate the cooler. In addition, the Omen 45L separates the power supply, which is another source of heat in a computer. Overall, HP’s Cryo Chamber concept should outperform traditional designs in terms of cooling performance.
If you’re worried that HP’s cooling system would “lock you in” to their cooler, think again. HP says the case is created with “future proofing” in mind. In fact, you may open up the Cryo Chamber and install a 360mm radiator inside. The Omen 45L can also fit a power supply with a length of up to 200mm and full ATX motherboards.
And you can do so while pleasing the FCC, because the tempered glass window is insulated from RF emissions, which your average DIY case isn’t.

Overall, it’s an excellent idea, especially considering how hot your computer’s internals may become on a hot summer day. Internal temperatures might be much greater than the 77 ° HP tested it at. Giving the radiator its own cooling chamber will only help a gaming PC’s cooling performance.
