So for reference my GPU temp is around the 40c mark at idle, and when I launch Rainbow Six Siege my GPU temps will literally increase to 75c in a matter of seconds.
My specs:
cpu: AMD Ryzen 5 5600x
gpu: Msi GamingX Geforce Gtx 1660 super (Twin Frozr 7)
ram: Corsair Vengeance LPX DDR4 3200MHz 2x8gb
psu: Corsair RM750
mobo: Asus x570 Tuf -PLUS WiFi
case: NZXT 210
To my knowledge my BIOS is up to date and running in "asus Optimal" mode which seems to be a modest stock OC setup, I also have up to date graphics drivers using Geforce Experience. I have a custom fan curve on MSI Afterburner I use to keep the temps in a range I like and I don't mind the extra sound, and I don't currently have my GPU overclocked. I have been trying to maximize the airflow in my case and I have currently 2 intake fans on the front, and 1 exhaust fan in the back, and a stock Wraith cooler on my CPU currently which keeps my 5600x in a reasonably healthy range when under load although I do plan on upgrading this. So to get to the issue- when I launched Rainbow Six Siege I noticed my GPU making more noise than usual, and it even seemed to have an audible "whine" which I could repeat at will by simply ALT+TAB'ing to hear it come and go as I opened and minimized the game. I always usually play with a Task Manager in the background so I can keep an eye on any unwanted programs starting or eating up my resources so I immediately noticed the GPU temperature. I am well aware that 75c is perfectly normal in most under load instances but this just seemed odd to me. I ran a Kombustor stress test with everything stock for around 10 minutes and my GPU temp held steady at 75c with 99%utilization. The problem is that in the Siege lobby my GPU is doing almost no legwork, and it is really off-putting to see my temps go from 40c to 75c in literally 10 seconds.
Any and all advice on this topic would be well received and much appreciated as I have exhausted about all I know in terms of fixing this (including a full re-install).
Thanks!
