I hope I will explain this best as I can.
I have Gainward GTX 650Ti BOOST2 card, and it has been working flawlessly for a year and a half.
I don’t know what changed in last month, but with both 331.89 and 343.22 the card overheats.
When I open my nvidia-settings I can see that GPU temp is really high, and ‘Speed (%)’ does says that the fan should be high as well, but the ‘Speed (RPM)’ is sitting at zero.
If I ignore this and keep on playing a game or something, my driver would crash and I would get black screen - possible because my GPU temp goes over 100 degrees (sometimes the PC hangs, other times I can hear stuff going on in background).
If I stop playing and relieve the GPU, it would sit at that temperature and given enough time the fan would spin up and cool out the card. After that the fan will go again to a complete stop and the cycle repeats.
-I checked to see if my card is dusty but it is completely clean and the fan is moving with ease, so it shouldn’t be physical obstruction issue.
-I also checked to see if any cables could interfere with the card’s fan and there aren’t any
-I also tried to see if there is a pattern, or exact amount of time at which the fan will turn on or off, but it doesn’t seem to be the case.
-I also tried to see if manual speed control would make a difference (using ‘Coolbits 4’), it is completely the same with either max fan speed (73%) or the min fan speed (30%)
Please advice what next, because I cannot think of any further diagnostic steps that I can make.
Thanks in advance,
