PNY 9800GT 512Mb - No fan control anymore?

post #1 of 8
Thread Starter 
Hey,

This card in my brother's rig isn't controlling the fan properly anymore, it spins up to I'm guessing about 50-60% and just stays there whether at idle or load.

It does it from BIOS so not a software issue and does it in my comp also so definitely something going on with the card. Have checked the PWM connector's in properly, which it is.

Temps are all good, I take the system aside and reapply thermal compound/remove dust every few months so it's idling at about 40*c under the stock cooler.

Any ideas, or is something on the card roasted?

Cheers

Nope, nothing's changed on it other than being cleaned out (which I only have to do regularly since it's in a very dust-prone area), it was booted one morning and just... like that.

Can't find any info on it, I presume the PWM chip's had it or something but not sure.

That's mostly the problem though, atm it's too loud for browsing since it's so damn distracting but it's not powerful enough for load

try using msi afterburner to see if it will let you control the fan speed. as for first boot the fan should spin to 100% then down to 40% on average, it will not spin much faster till the card gets way hot.. with afterburner you can change the fan speed profile, and at what temp it increases the fan speed.

Already tried, nothing works, certain it's hardwareside, just can't figure out where to start

Thought I'd bump this for anybody with the same problem who stumbles on the thread, the card failed completely a few days ago with lines/boxes, something gone on the core of the card. Reflowed it and the fan control is suddenly working perfectly again; also is the second DVI port which hasn't played ball in a while.
