![]() ![]() While you can create your own custom loop liquid cooling system, they’re difficult to make – but they perform far better than any other solutions. A fan is attached to the radiator, much like with a heatsink, to dissipate any built-up heat. Add liquid coolant through tubes and radiators to help cool the CPU. Liquid coolers use small shrouds to attach to the CPU. This is the most common setup and the reason you’ll hear the fan running harder with increased CPU usage. With air cooling, the heatsink with a fan is attached to the CPU using thermal paste. It’s also beneficial to understand the difference between air cooling and liquid cooling, which are the two main ways CPUs are cooled. If you want to look into this more, see our guide on how to choose the right CPU cooler for your PC. If your CPU cooler/heatsink is out of date, then the reuse of this heat won’t be cooled down. The entire process is essentially reusing the same heat that was originally generated by the CPU. Then, as a general rule of thumb, keep the processor’s temperature 20 to 30☌ (68 to 86☏) below that maximum at all times to ensure you’re not toeing the danger line. You’re looking for a statistic called “TJunction” or “TJ Max.” This number is the absolute maximum it can take before problems arise. If you’re using an Intel CPU, search for the specifications of your processor. If you’re not doing much, an average CPU temperature is usually near this range. ![]() At this time, an average idle temperature of around 30 to 40☌ (86 to 106☏) should be fine. “Idle” is when you boot up the PC but don’t open anything, and the operating system isn’t doing other intensive things (such as Windows’ Superfetch process). Regardless of your processor model, ideal idle temperatures don’t differ much. There are certain parameters you should stay within while idle and when under heavy processing. For instance, a temperature of 80☌ (176☏) can be shrugged off by some processors in some scenarios and seriously damage others. As such, they each have their limits as to how far you can push them. Different CPUs are built in different ways. This is where things get a little complicated. Tip: assign specific CPU cores to applications to further control your processor. Linux fans can check their CPU temperature using the psensor tool. Thank you all for taking the time to read my post.Mac users can grab Fanny, which doesn’t go into as much detail as Speccy, but sits as a widget in your notification center for easy access to your CPU and fan stats. My question to all you good people is, do you think such high coolant temp (as well as high CPU peak temp) is reasonable with this setup? I've reapplied thermal paste and re-seated the pump, I don't think I could have done something better there.Ĭould it be that AIO cooler is no longer performing as expected due to wear and tear over the past two years (I know those things have a 6y warranty though). I'm suspecting that the when the GPU gets hot, it dumps hot air that travels through the AIO radiator contributing to the high liquid temps. In almost all (gaming) cases though, liquid temps rise to around 40 C pretty easily, and on the more demanding games (Cyberpunk) can peak at 45 C (that's the max I've seen). While playing demanding games (Cyberpunk 2077, Control, Doom eternal) CPU temp sits at around 70-78 C whereas on less demanding games it stays cool at 58 - 67 C. ![]() Under load, CPU can get somewhat hot (70-80 C) while running benchmarks, I have PBO enabled with limits of 185 PPT, 135 TDC and 150 EDC with curve optimizer per core ranging from -10 (good cores) to -25. I get decent idle tempratures (33 - 37 C die average, 40-45 C Tctl/Tdie) and coolant temp around 30-34 C, ambient temp is around 24 C. Let me list PC specs:įan setup: 3x bottom and 3x side QL 120 intake running at 1000 rpm, 1 QL 120 rear as exhaust (1140 rpm), AIO mounted on top as exhaust, usually running at around 1200 rpm fan speed and 2700 rpm pump (100%). I'm running a 5950x CPU cooled with a 2 year old NZXT 圆2 (280mm with 140mm fans). ![]()
