MSI GTX660 Twin Frozr, only 1 fan spinning

[JacobusTracks]

Hello,

I recently bought a MSI GTX 660 Twin Frozr III and i noticed only 1 fan is spinning.
Now the temp stays at 33 just browsing the web and goes to around 60/65 when playing a simple game, the other fan then does not go on. Im kinda afraid to let it go above 65 cause of overheating.

The fan does spin a couple of rounds at boot up.

Any suggestions?

Greetings,
Jacobus

May be by default system not in overload only 1 Fan run, You should check it on a overload test, Ex by run: Unigine Heaven Benchmark. Because my 970 2 Fan never run under normal Tasks or play LoL, Fan only run when I stress test or heavy gaming keep GPU maximal around 60 degree !

I just ran valley benchmark on high settings and the temps were around 70c, still the second fan did not go on.

900 series cards are design to have semi passive cooling. This is not normal behavior for any other series of Nvidia GPUs.

Yeah i thought so. i bought it second hand, can't send it back for RMA.
Can't i just replace the cooler? For example with the Arctic Accelero Twin Turbo 2 ? Anybody have experience with this?

It is weird that the fans start spinning on boot up though .

If the fan spins normally during boot or when running another OS, then it is likely a power management issue and not a hardware defect.

So, how do i test this? Should i try connecting the cooler directly to the PSU with a molex connector or something?

I did read something about flashing the bios but i have no idea how to do this.

I just installed SMCfancontrol and i see that the 2gpu fan (the one not working) is on 30rpm.
Anyway i can adjust this?

Also on HWmonitor it only has only 1 GPU fan.

Would something like this work?

Make sure the fan connector is fully seated.

Ok, i gues il just take the cooler of, check if it is clean and reseat the connector.
