Hello, when i play games like EFT or Rust or whatever (Except R6 that works) my screens will randomly turn black with a message "no signal" and the GPU will put fans at 100%
I have i think normal temps in game, it's around 65°C for the GPU and 45°C for the CPU and a voltage of 1250mV in game for the GPU
Config :
Mb :Aorus B450m Bios version : F32
GPU: Rx590 8GB Gigabyte
CPU : Ryzen 5 2600
RAM : Ballistix 2x8 gb 1333 mhZ
PowerSupply : Seasonic 620w M12 II
SSD : Samsung 860QVO 1 To
HDD : Seagate Barracude 1To
Thx for your answers
(I'm french, so sorry for my english ,_, )

Well, I figured out that when I open my pc case I don't have this problem, so I think I'm gonna buy a new one, because on this one air don't flow very well. Moreover it also works (for now) with the pc case closed If I change the power limit of my GPU, I have a Rx590 and so I can change that on Radeon Software, but watch out with those setting because you can easily get problems if you change things too much, I know that with Radeon Settings it's "safe" but tell me which GPU you have and I'll try to see

hey! i’d try to repaste the cpu and gpu just to be safe. i had similiar problems not so long ago and i had to replace my PSU. it was not a bad one but only 500 W without any rating. but yeah a bad case can boil up your pc in no time. try with different fan setups as well!

Hi Ehot - great info. I use the AMD software, all I have done is click "E-Sports" setting and I have remapped the GPU fans:
Speeds 38, 42, 50, 75, 100
Temperatures 30, 50, 60, 70, 80+.

By doing this and limiting the FPS (in game) to 115 it resulted in GPU temp dropping from 76 to 69 degrees.

Peterparker_hu - thanks for your reply also! I am toying with mounting a fan underneath the floor (next to PSU) to help with PSU/System cooling. In terms of repasting (coming from a Mac background) I have not thermal pasted anything before - is this something that wears away? Components are a few weeks old

paste wears away in months even a year so it’s not the case then. if you have heat issues then you shouldn’t worry about that PSU luckily just get a case with decent airflow ;)
