My GPU fan is not spinning when it should

[lonskyne]

Hello! I have had this problem for a while now and don't really know what to do to fix it (if that's possible).


So, let me explain: My GPU fan is not spinning and the temperature goes up to 70°C (158°F). I know the fan works because when it goes to really high temps (over 80-85°C) it starts spinning like crazy.

In HW Monitor it says that the fans are spinning at 40-50% on idle but they are not spinning at all. I tried doing something with the MSI Afterburner. The fan doesn't move at all until the fan speed goes over 80%.

I did a test to see what happens and this is what I've got: 50% fan speed (nothing), 60%, same,70%, same, 79%, still nothing, 80%, starts spinning at 80% (like it should). I'm having some issues with my PSU, I'm getting a new one in around a week. Can this be happening because of something related to the PSU? Or is this something else and is there a way to fix it myself? I have been able to leave Afterburner in the background while playing games (CS:GO mainly) and set it to 80% and its doing a great job. The temps are not going above 45°C while gaming with the Afterburner in the background. Thanks you all in advance!

Nvidia Geforce GT 630 GPU

AMD Athlon 7750 2.7GHz Dual core CPU

4GB Kingston HyperX DDR2 RAM

In MSI afterburner, set up a fan curve to prevent this.

I mean, I guess there could be something wrong with the power draw to the fans, but I would assume you would see other issues with the gpu first. I would try downloading speedfan first and trying to change the fan settings yourself. You may be able to force it to kick on by changing the minimum and maximum speeds/temps.

I have tried setting up the fan curve myself. It doesn't spin at all until I get to ~80%

When I'm gaming, iI turn on Afterburner and then it runs at 80%.
