High temps with: DeepCool Assassin IV on Ryzen 5900X

[LillaMollet]

Hi! 

I have a problem with my system temps on the CPU with the cooler on the title. I have no idea why this is happening. It hits like 90° on games and it switches temps like crazy. Sometimes it is 40° and sometimes its 80° on normal use and in gaming it hits 90. Is there a problematic with my cooler or something?

Regards

André

What is your case? Airflow setup?

 

Other specs?

 

Might just be a bad mount.

Its a BeQuiet Pure 500Dx and i have two front and two top and one back.

Front is intake. 

One top is intake.

One top is outtake.

Back is outtake.

 

All fans are bequiet fans.

 

I have a 1250W cooler master power supply.

 

A asrock b550 steel legend motherboard.

Hows the thermal paste and mounting pressure? and fan speed? Computer placement? Floor, desk, cupboard etc

 

Also move that top intake to a 3rd front intake, youll see better results as its directing it more effectively and not recycling hot air from the top exhaust

If i understand this correct, should both my top fan be intake and the back is the outtake? 

Im not speaking english in firsthand  

 

Im using performance mode on all the fans. They are not very loud (Thank god). I have seated it not the hardest as stone but hard enough to be on there. Thermal paste is recently replaced with thermal grizzly.

Better with pictures, so your current setup sounds like its this

 

But this would be better

 

So basically bring the fan around to the front instead of the top
