CPU Temperature - who to believe

Post by pjaj »

I'm running an AMD Ryzen 7 2700 and was curious about the CPU's temperature so I installed Speccy and was alarmed to see that it claimed all 8 cores were at 100 - 103 degrees C when FAH was running. However this only dropped to 85C when I paused FAH. This is suspiciously high, it's got ample thermal paste and a good cooler. Speccy also claims the GPU, NVIDIA GeForce GTX 650 Ti Boost, (OK it's old, but completely adequate for all my other needs) idles at around 32C rising to 73C with FAH, which agrees with another temperature monitoring app, TechPower.
However, I also installed AMD's Ryzen Master which says the idle temp of the CPU is about 34C rising to 55C when FAH runs. This time TechPower agrees with AMD.
I'm a bit confused. Is Speccy measuring something different from the other two? The AMD app doesn't seem to be raising any alarms.

Welcome to the F@H Forum pjaj,

Please note that this is a known issue with Speccy: https://community.ccleaner.com/topic/52 ... ading-hot/
Do note that F@H Client will stress your CPU so as long as you have a decent cooling system in place, there's nothing to worry about.

Thanks, I hadn't see the thread about Speccy, but I suspected that may be the case. I won't worry about it.
Now what's that smell of burning .....

Believe your Ryzen should throttle at about 95C … Trying another hardware monitor (HWMonitor is what I use but other/better exist) might give you more reassurance than you olfactory senses :)

Thanks, but I think 3 different monitors will do :) ! I'm happy to know that Speccy does not report the correct temperature.

Ryzen is a bit of a special case.
I believe the reporting structure is different from older chips. So similar to how Intel changed in Core2 chips, software needs updates to handle the difference.

If you use HWiNFO sensors only, you'll see three different values,
CPU (Tctl)
CPU (Tdie)
CPU Die (average)

Speccy I believe reports CPU (Tctl), which should normally be higher. (Tctl is 10 degrees higher than Tdie on mine too.)
AMD Ryzen Master reports CPU (Tdie).

Probably good to trust the AMD Ryzen Master...
