I am having CPU cooling issues and don't know what to do! (lemmy.world)

I just put together my new build and i am idling at 60C. I am using a Ryzen 7 7700 paired with the Corsair H115I ELITE CapellIx XT. I have coolant temps of 30c and idle temps of 60C+. I should note, i am not using the tension CPU bracket that i thought this cooler came with(it doesn't) and instead i am using the 4 screw AM4 bracket. I only mention this because i am worried it may be a tension issue since i always see them install these with the tension bracket when looking on youtube.

Probably the bracket. Or you did the compound wrong and trapped an air pocket

I keep seeing people using this tension mount but this cooler did not come with one.

I actually built a PC for a mate with almost exact same hardware a couple of weeks ago. Temps were perfect from get go and this time round I used stock thermal paste from the cooler.

Unmount and clean off thermal paste. Reapply thermal paste. Carefully place pump back on thumb tightening each screw in a star shape. Do a few turns per corner to ensure even pressure. TBH, I didn't really know when to stop screwing as it didn't feel like it was getting tighter to an end point and I was also being aware of overtightening too. From memory, I think I did maybe 12-16 turns of each screw? Good luck!

That worries me because my four thumbscrews can be tightened all the way down.

Your CPU is likely fine.

In your screenshot, we can see that the CPU utilization is at around 10%, this is means that you have the equivalent of one full core usage during that screenshot (and, in fact, we can see that around 3 cores are at their "all cores" maximum frequency).

As a reference point, idle equals:

  • low to no CPU usage (2-3% maximum usage)
  • No program running in the foreground. If one is, it shouldn't have frequent updates (Your corsair whatever is a no go)
  • Background running software should be lightweight, so no corsair RGB software running in the background as it is known to wake CPUs quite frequently

Considering that your PC is not idling, Ryzen CPUs are known to be "race to idle" (aka use as much power as possible to go back to sleep as fast as possible) and that 60°C is a normal temperature for 10% CPU usage in summer. Again, your CPU is fine.

I mean, what if they live in Australia or South Africa? Not summer there. It's winter.

I'm curious if you ever figured this out.

It looks like you're using an AM4 bracket on an AM5 CPU, was that the problem?
