Processors

The problem is that, guided by these high temperatures, the motherboard regulates the speed of the coolers. In game 3700x temperature jumps up to 81 degrees, in Cinebench R20 - up to 87 degrees at a temperature in the room of 25 degrees. My motherboard spins up the cooler to full speed after 70 degrees. And the temperature is constantly jumping within 15-20 degrees, forcing the cooler to change speed. Very noisy!

That is kinda what U was thinking...

Hey I have same processor and Dark Rock 4 too. My temps at idle are around 45-55 C. In stresstest temperatures are around 80-87C. I think its pretty normal and ok for this processor

[martaszla]

Yeah thats why I bought Dark Rock 4

I've been futzing with this issue all day on 3600x and 3700x....i "believe" I've narrowed it down to the beta bios on 400 series and 300 series motherboards possibly reading incorrect temps..simply because there is no way a 3700x on a custom loop and a 3600x on a 240mm AIO are both running at 80c+ with cold air blowing out of the rad..

Hi. I have a Wraith Prism fan on top of a Ryzen 3700x, not only was it very noisy, but didn't keep the cpu temps down. I downloaded and installed the AMD chipset drivers v1.07.29.0115 from Guru3D. The Ryzen power plan at default balanced, was showing Min=98% and Max=100%. I changed it to Min=5% and Max=100% but temps were still high with the noisy fan, so i reduced the Max to 99% then the fan speed dropped immediately.

Cpu temps now under load are 60*c to 65*c and the fan is very much quieter, at idle the fan is barely audible. Why the latest power plan has a balanced Min of 98% and setting the Max=99% stops the fan sounding like a vacuum cleaner i've no idea. 1% less on the Cpu is not noticeable on my system a.t.m. Perhaps there is a reason for this anomaly and perhaps someone would be kind enough to explain it.

Hi. Just a thought about the balanced power plan settings at 99% curing my problems, could it be that instead of the settings going from 1-100, it could be going from 0-99 . As i said, just a thought.

With Corsair H105 (240mm AIO) 3700x temperature in Cinebench R20 jumps up to 73 degrees at a temperature in the room of 20 degrees. AIO radiator is cold during the test. My motherboard spins up the AIO fans to full speed after 70 degrees. Very noisy!

At the same time, AMD supplies 3700x, 3800x, 3900x box processors with AMD Wrath Prism coolers. Something is wrong somewhere.

By the way, large air coolers have a drawback - they heat up from the video card

Dark Rock 4 is designed for 200W TDP, and the 3700X has a 65W TDP. So I would say something is wrong.

Ok but where is problem? I have fractal design meshify c 2x 140mm in front, 1x 140mm on top and 1x 120mm on back. I think I have very good airflow.
