Ryzen 9 5900x cooling issues.

[Santipro]

Hey there,

I'm running a Ryzen 9 5900x with a Corsair Hydro H110 and am facing high idle temps (50°C+) unless my fans ramp up.
Is this an issue with my CPU or the the H110 just not made for modern CPUs and their high TDPs?

I have no experience with hardware past 2016 so I'm very rusty when it comes to estimations.

5900x is a very power hungry chip and thus outputs a lot of heat. I would try and change some settings in the BIOS so when its under very light loads it underclocks itself and doesn't output as much heat. Your AIO could also be broken.

Do you know what voltages the cores are set at?? It might be pinned at the max frequency and causing a constant voltage to be applied to the cores. Check in HWinfo64 under VIDs to see what they are. 

 

On a side note, don't forget to update your signature (under Account Settings when you click on your username in the top right).

Hey so first off, thanks for the reminder haha.
I've never used HWinfo64 before but according to what I can see the Voltages seem to be fluctuating as seen here.

Am I not getting something here?

dont think the AIO is broken. might have to look at some bios settings indeed. thanks!

Looks like the cores are boosting to +1.4V when at 4.4GHz. That might be why the idle temps are high. Also as @Sky7734said, these chips can be power hungry out of the box but with some tuning to lower those voltages at high frequencies, should resolve the high idle temp (and also high temps under load if experiencing the same). As long as you feel coolant moving through the AIO tubes (one hotter than the other) and feel a vibration from the pump spinning, the AIO should be working. Are you sure its also not a bad mount of the AIO on the CPU?

Even with a -.075v offset I get similar results with a Kraken Z63 cooler.  the 5900x just runs hot at idle.

yes, i'm quite confident on that. i will lower the voltage and see what happens. i appreciate the help!
