High CPU Temperature in BIOS

Hey guys,
X399M Taichi CPU temperature is wrong in BIOS.
It shows as 69 degrees, but in Windows10 only 34 degrees.
Due to the wrong CPU temperature, the fans are always 100%.
Please ASROCK fix this in next BIOS.

hi
due to the reference of the OP to the fans I think that the problem is the well known one thet you can see in the forum first sticky thread.

The bios exposes two temperatures one for the fans (tDie temperature plus an offset of +30°C for the TR) and one for everyone (tDie).
The bios shows also the M/B temperature, that can also be set as reference for the fans.

So in Windows may be you see only one of the latters (tDie or M/B) while the fans are set to monitor tDie that to fans is exposed with the offset of +30°C.

To adjust them bahaviour use the Fan-tastic menu in bios to shape your fan curve and the sensor reference

hi

while we wait for someone from ASRock, my two pence.

You should say which m/b and bios you have.

That said, actually any bios should have only CPU (the old tCtrl) and MB sensors shown, so I think you have an old bios.

For the temperature cap, 100° and the offset is for the fans, for what I've understood, while the real cpu temperature limit is hardcoded in the cpu itself (for my ryzen should be 85°), so once there it starts throttling in order to reduce the load and keep the temperature there.

This is the behaviour I observed. For istance, with heavy stress the temperature rockets to 80° (and so do the fans...) than gradually in few minutes reaches 85° and stays there forever (or until I kill the stressing processes).

I never had a shut down due to the temperature level.

Anyway you can test it yourself, simply burn an ISO (win PE or linux), boot it and stress the cpu (for linux I use stressng with matrix option), so even if you have a shutdown, you don't put at risk your working system and you can tweak more.

Thanks for responding. Sorry I didn't mention my m/B. It's the same as the OP on this thread, which is why I didn't mention it. Taichi x399, with UEFI 3.50; the latest. And there is a TCTRL temperature sensor option for the CPU fan control. It's the only one that controls the curve. I think the Threadripper has a higher temperature threshold than your CPU. But I may be wrong. Thanks for checking in.

no you're right, normal ryzen +10°C while TR +30°C offset
