GPU fan problem. Whats causing it?

post #1 of 5
Thread Starter 
Hey guys,

So recently my second GPU has been acting up. For some reason the fan RMP will continuously stay the same speed whether it is at idle of whether im playing a game in full screen.

Im using MSI afterburner and GPU-z to monitor the fan speeds and according to them the second GPU is set to 60% fan speed but its running at 1070 RMP at idle and load.

Where as the other GPU (the main one) is running at 60% but at 3600 RMP. A pretty big difference.

I haven't checked to see if there is a problem with the wiring on the cooler just yet. I figured i would post on here to see if anyone else has run into the problem before.

Any help would be greatly appreciated

possibly the card is broken? and have you tried running the second gpu alone (pull out the main one) and see if that makes a difference, also does gpuz and msi support control of both fans?

Pulled out both graphics cards and only put the one in that was having problems and it still continues to run at a low RMP when its set to a high fan speed.

Ill take a look at the card now and see if there is any damage to it or perhaps faulty wiring. i can't imagine what the problem is. I suppose if worse comes to worse i could try and RMA it.

ohh also to find out if its the fan thats screwing up cross wire the fans (i.e plug gpu1 fan in gpu2 fan slot and vise versa) then you can immediately assume if its the fan or the gpu

I tried what you have suggested and it looks like the fans are a dud

Ive looked at alternative VGA coolers for the 5770 and there doesn't seem to be a whole lot.

Does anyone know if MSI would sell me just the cooler? I don't think they would but i guess its worth a shot.

Plus, the real only problem is the fans, not the heatsink. So that got me thinking if i could order the fans directly from the manufacturer or perhaps order them through MSI.

According the the sticker this is the manufacturer and fan type thats on the 5770.

Hopefully i could do something along those lines.

Anyways, thanks for the troubleshooting help BadAssClocker
