Question cpu running hot

[Khillh]

So I'm having a strange cooling issue with my CPU. It started running a little hot. Idle at 60c i run an Aio pump It's a Corsair H100i I figure its run out of juice since its a closed loop and all. So off to Newegg, I go and I decided to buy a new LIAN LI Galahad II Trinity Performance 360. Well, my performance got a little hotter at idle. Well if you haven't installed a LIAN LI they are not the smoothest installs they take some practice so I think bad sit so I do it again high idle. Okay, I think bad cooler this time around I go with a brand I know a CORSAIR iCUE LINK H150i. Good sit but again high idle temps. I turned my AI overclock off I'm in a Dark Base 700 case so I'm expecting hotter temps but I'm running an open case with these temps. Thermal paste is Thermal Grizzly Kryonaut. Not sure what could be causing these temps.

what CPU are you running?

is aio intake or exhaust?

What are other parts in PC?

 

[Khillh]

CPU: 11700k
GPU: 3070 RTX
MB: Rog Stric Z590A
Menory: 32GB DDR4 3200
AIO Fans exhaust

Your cpu does not require high end cooling.
Noctua maintains a list of suitable coolers.
Here is the list for the 11700K:

Intel Core i7-11700K | CPU Compatibility | Noctua Compatibility Centre

Series: Rocket Lake-S, Socket: LGA 1200

Your case is an excellent one for air cooling.
You can install a cooler up to 180mm high. that is enough for Any cooler.
Use two front 140mm intake fans which will supply sufficient airflow for the cpu cooler.
Only use a single 120mm exhaust fan to direct the airflow over the components.
Perhaps more important, it will cool the motherboard vrm's which can get hot as well as supplying adequate airflow for the gpu.

if he has an AIO now, I would try using it as intake and see if CPU temps drop. It being exhaust means it sucks all the heat from GPU into it before cooling CPU

Tried switching the fans to intake and still running hot. Since I have the AIO already I'd rather try and run this down before I return it and try another cooler. If I have to I will but I'll cross that bridge when I get there. The main issue I guess I'm worried about is that I went from normal idle temps of 40c to now running 60c suddenly and changing coolers seems to have no effect on cooling. I just recently changed this case and this heat issue did pop up soon after this case change. But I can't imagine that is the problem it's just a coincidental thing. I know everyone is kind of focused on my cooler thing but that's not really what my question is about. Why would my cpu suddenly go from 40c idle to 60c idle and then with replacement coolers not go back below 60c. Is this a truely cooling issue or do i have sort of another issue that I have to chase down?

Programs or services keeping one or more cores active is what comes to mind.

We only focused there as it seemed to be main topic of question.

Try a clean boot and see if it changes anything - make sure to read instructions and make sure NOT to disable any microsoft services or windows won't load right - https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows

It doesn’t delete anything, it just stops non Microsoft programs running with start. Easy to reverse.

if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.
