Sure, sheer power makes a huge difference to your PC’s performance, but efficient cooling plays a huge role as well. Yes, better cooling is the answer to better desktop gaming, and HP’s unique new traditional closed-loop cooling caught our attention at CES 2022.
HP’s clever idea like the “powerful” PC case might not impress you with the CyberPower PC, but this truly innovative design could be more practical. HP has already patented what it calls Cryro Chamber, a case that effectively reorganizes the CPU by moving liquid coolant out of the computer’s hot interior.
For starters, most gaming computers today use all-in-one closed-loop coolers which are basically small-size car radiators. They remove heat from the CPU and consume the lost heat from the computer, passing it through the cooler. The problem is with the overall design of the cases themselves: you have a rectangular box where the coolant is usually installed in the back, top, or front of the system.
With systems that install the cooler on top or at the back, heat from the CPU is transmitted through the water block and hoses to the cooler. However, the cooler is still installed inside the computer, so even though the heat is expelled through the cooler, the cooler is first “cooled” with air that has already been heated from the graphics card, voltage-regulating units, and other components inside the computer.
You can see an example of this in HP’s smaller Omen 25L desktop computer, which uses the traditional setup found on the vast majority of computers. The Omen 25L appears to be thermally engineered to reduce hot air moving through the top-mounted radiator, but it will always be somewhat warmer than cool air coming in from the outside.
With the new Cryo Chamber, used in the larger desktop Omen 45L announced at CES, HP solves the problem of feeding the coolant with hot air by moving it up and out of the PC case. External liquid cooling is not new. The early days of dedicated liquid cooling relied on radiators located outside the enclosure, with an inlet and outlet leading to it (yes, those are the two vents in your old case). So the internally installed radiators have eliminated all of today’s external radiator systems, at the expense of the internal hot air intake.
So far, with the Cryo chamber shown below in the Omen 45L. You can see the water block of the closed loop coolant and the hoses feeding into the Cryo chamber installed above it. This method means that fans installed in the front suck in the outside air and then it is discharged from the back, cooling the coolant. The gap is not ventilated inside, so there is no cross contamination with the hot air generated in the main computer compartment.
You might be a little confused by the image above, but this is part of the HP render showing the Cryo Room. Unlike conventional computers, you can see cold air being sucked in from the front and exhausted from the back. Meanwhile, heat energy is transferred through the fluid in the hoses to the coolant that feeds the cooler, unadulterated air through a duct that penetrates into the middle of the enclosure. Negative Nates might say that atmospheric temperatures don’t make who – which Significant difference, but HP said its tests show that the Cryo chamber of the Omen 45L delivers a 6°C drop in temperatures at full load with room temperature at 25°C (or about 77°C in units of freedom). , was done against a Cooler Master 120mm CLC which was likely installed inside the case, like the smaller Omen 25L above. With a larger 240mm cooler up front, the difference might be a little closer.
HP doesn’t just turn off the coolant. The Omen 45L also shuts off the power supply which is another heat source for the PC. Finally, the HP Cryo Chamber design still has to improve cooling performance over conventional designs.
If you’re thinking HP’s cooling design “locks” you into the cooler, HP has already thought about it and said the casing is designed with “future-proofing” in mind. You can, in fact, open the Cryo Chamber to mount up to 360mm of coolant inside. The Omen 45L can also accommodate a power supply of up to 200mm in length and full ATX motherboards (244mm x 305mm).
And you can do this while keeping the FCC happy, as the glass window is shielded from radio frequency emissions—something a typical “do-it-yourself” canister doesn’t have to contend with.
In general, it’s a good idea, especially when you consider how warm the interior of your computer can be on a summer’s day. At 77 HP tested on (a reasonable summer day in a house without air conditioning), indoor temperatures could be much hotter. Giving its own heatsink cooler frankly, can only improve the cooling of any gaming PC.
