Idle Temperatures on 5900X - Are they Normal?

[MidNate]

I'm trying to figure out if the temperatures I'm reading on my AMD Ryzen 9 5900X are normal or not. On idle, my temperature readings are between 62°C and 64°C. While under load, they range about 10 degrees higher. My case is the Corsair 5000D so airflow shouldn't be the problem. The only things that I can think of as to what it could be are the thermal paste and I just need to redo that, orientate the fans and radiator differently, or I might need to get different fans that are more flush with the radiator. Like I'm just looking for a second, third, fourth, etc. opinion as to what could be going on or if the temps for this CPU are just normal. Any help is appreciated!

5000 series caused a lot of spook due to the high idle temps but it was quickly established by AMD that it's safe and normal behavior for these CPUs. They have really high idle voltages, but since it's idle they're not pulling much current, voltages usually drop under load as the chip clocks up and pulls more current, thus why the temperature doesn't climb much under load.

62-64c is safe but certainly higher than I would expect even for Zen3. 

 

However, this doesn't tell you a full story. 

 

With HWiNFO open monitoring temperature AND clockspeed across all cores, start a Cinebench R23 multicore test and report back the max CPU temp, all core clockspeed and score. (Ensure CB is set to advanced benchmark so it only runs once) 

 

tl;dr, idle temps aren't helpful, load temps AND all core clockspeed tell us how well your cooler is performing.

I'd change that to load temps and benchmark scores, since it's not uncommon for Ryzen chips, even in HWINFO64 and Ryzen Master, to read out the wrong clock speed. I've got screen shots of my chip doing 4.7GHz in R23 that are 3000 points lower than it doing 4.4GHz, for instance.

Yeah you're probably right. I've got saved R23 runs with exactly that happening.

So I ran Cinebench R23 and rant the stress test while looking at HWINFO and from what I can see, the temperatures are way different and look more normal. Idle before running the test was showing a steady 51°C with the stress test showing up to 69°C (nice). So I guess the NZXT program is reading a different temperature somewhere because the other stuff is showing temps being normal and the CPU is fine.
