Hello,
This is rather complicated but I'll try to explain as best I can. I had a Radeon 4850 fitted and 3 days ago I opened my PC to fit an extra Sata HD that I had laying around, 20 mins after I fit the HD the pc shut itself down. I powered on again and it shut down in 20 secs.
I waited 30 min, powered on and instantly loaded HWMonitor to check temps, my gpu temp was idling at 92c then 93,94,95.. it was going up. I shut down and opened the case again. Took out the card and made sure the fan was dust free and the card fitted ok.
I put it back in and watched carefully when I powered on, the fan WAS turning but only about 20% speed. I went into CCC and tried to adjust the manual fan control, I set it to 50% and hit apply.. no change, set it to 100%, no change.. set it to 0% no change!!? (have tried ati tray tools and MSI Afterburner too, both show the fan as whatever manual setting I put into it but in reality the fan neither speeds up nor slows down)
I thought perhaps the fan controller in the card was broken so I took out the 4850 and fitted my older 4670 card. it was fine and since then (touch wood) the pc has been fine.
but...
Still, when I go into CCC and try to set the manual fan speed, although the computer says the speed has changed, it certainly hasn't changed. This fan is loud and no matter what I set it on, 0% or 100% it stays the same, idling speed.
I wondered if it was a software problem and today I uninstalled my graphics card drivers and downloaded and installed the latest ones from AMD.
No difference, I can set the manual fan speed but the fan itself has ZERO change. also I downloaded MSI Afterburner and tried to change the fan speed in that, and the software said the fan speed was changing but in reality it wasn't changing from idling speed.
I know for a fact that manual fan control did work as last summer when it was hot I manually turned my gpu fan up to 75% then when it got cooler I put it back on auto.
I did get a virus alert the day before I did this, could the virus have damaged the fan control or is there another reason?
Right now I'm stuck with this old 4670 and unable to play any newer games, I don't see the point of buying a new gpu if what is causing this is not fixed.
PLEASE HELP!!
