Issue with GPU Fans.

MysteriousAeon · December 8, 2021

I'm having a weird problem with my GPU fans. The GPU is a MSI GTX 1080 ARMOR and the PSU is a Corsair TX750M. the GPU has two fans. the left fan can't spin to full speed and slows down on its own, like it struggles. The right fan cant start spinning on its own, I have to spin the middle with my finger and only then it stays spinning. These issues happen even with MSI Afterburner fans on 100% (the fans definitely don't run at 100% even after its set though).

I'm only having fan issues with the GPU so I don't think it's a PSU problem. My guess would be the fan connector cable or just the fan bearings, I've already ordered new fans to replace but I wanted some thoughts from here as well.

Thanks in advance.

I think it's dusty. If you're confident get a compressed air can, open up the fan shroud, remove the fans and give the heatsink and fans some luvin with the air can.

I've already tried that to no avail sadly, only place I haven't cleaned is inside the fans and I'd have to disassemble the GPU to access those parts.

I'm sure you don't have to dissasemble the GPU (Graphic Processing Unit) only the fan shroud, but yes that has to be disassembeled. Well if the fan thats what you have to do, unless you simply order new fans from Ebay or something. Wont cost much but you still have to remove the fan shroud.

Look for videos on youtube for MSI GTX 1080 ARMOR disassemble and then you can maybe see if it is an undertaking you can undertake.

I might be mistaken since there aren't many videos of disassembly for this particular GPU, but don't you also need to remove the heatsink to remove the part covering the fans? I'd rather not bother with re-applying the thermal paste unnecessarily.
