Going over 80C when using CPU-Z stress test on R5 3600

[renchy_is_sketchy]

Finally trying to get the PBO and Core Performance Boost trying to work properly(?).

Now that i realised i hadnt installed AMD Chipset drivers, i installed them enabled the Ryzen Balanced Power Setting (99%, 100%) and ran CPU-Z tests.

The bench test ended on about 78 degrees, but the stress test however went over 80 and that was when i stopped the test since i read that over 80 degrees is bad.

Should i get a new cooler if i want the temps to be lower or is something wrong?

BIOS settings:

Basically everything on auto, A-XMP enabled, CPPC enabled, CPPC preferred cores enabled, Cool&Quiet enabled, Global C state enabled, as according to reddit.

I have 1 intake fan on the front, 2 exhausts on the top and 1 exhaust on the back, all 120mm.

Ryzen 5 3600

Sapphire Radeon RX 5600 XT 6 GB PULSE

Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3200 CL16

Corsair RMx (2018) 650 W 80+ Gold Certified Fully Modular

MSI B450-A PRO MAX ATX AM4

Also, basically every time i start the PC and go traight to Core Temp the temperatures spike to 60-70C.

80c is normal especially considering it was under a stress test 

Which is a load that your cpu won't hit in a a casual load 

It's completely normal.

Alright, thank you for clarifying.

I guess i'll just leave everything as is for now.

80 degrees is not really bad if we're talking about lifetime. It may impact how well your CPU boosts but it shouldn't cause a CPU to have a reduced lifespan in any noticeable degree throughout its useful life.

It is a "Stresstest" after all. Almost no real-world task will have such an impact on your CPU. If it stays below 80°C while gaming youre good. Quick and high temp spikes are pretty normal with ryzen. These spikes happen with my Nocuta NH-D15 aswell.

FWIW, on Prime95's SmallFFT test, my 3700X peaked at around 65 degrees before the CPU downclocked to base, maintaining 63 degrees without much noise.

 

In actual use, that's the temps I got mostly because my CPU was boosting more. The cooler is a Dark Rock 4 non-Pro

Why is it downclocking at 65°C? Never seen that with my 3700X. Normally downclocking happens at 95°C.

Nothing to do with temps. It just hit the PPT limit as the Small FFT test required quite a bit of power.

 

On Cinebench R20, it maintained roughly 4GHz whilst at the 88W PPT limit.

I could be wrong 

But since it's prime 95 with AVX 

I would assume it is the AVX offset 

Again I could be wrong as I don't know D13H4RD's setup.

Edit: and I was wrong lol

The is no AVX offset on AMD. That is just an Intel thing. However AVX instructions use a lot of power so you may be hitting PPT which will reduce the boost, achieving a similar looking result, but only if that limit is hit.
