Hey,

While using my pc, I noiticed a red light on my 4850. Shortly after my display went. I had to restart my pc. I found out the red light can mean overheating, so I opend CCC and looked at the temps.

It's at 36 degrees C, with 0% activity and the fan in on 0.

Is the fan not working or something?

I'm a total newbie, so be gentle :p
 
36c is quite cool, do you have any games or benchmark software you can run and check full load temps.
 
I also had afew problems with overheating on my 4870x2 best way to solve it is just enable overdrive in the CCC panel then when your going to game run 45% fan speed i have found the CCC drivers to be insuffciant at keeping ATI cards cool, a lot of the time the Fan doesnt speed up in time to stop the card from overheating with the auto setting.

Ah, I see.

Yeah, I'll have to do that. The thing is I wasn't running a game at the time, just normal browsing etc. Should I leave it on say 30% all the time?
 
The default running speed should be 27% but i'm not 100% on that maybe some one can clear that up for you:)
 
36c idle is fine, my old 4850 idle'd at 40c and games around 65c

left the fan at 20% then put it upto 40% when gaming.
 
just for reference my 4850 is running at 45c idle. However idle temps mean nothing. without load ones. Let me get this right, you get a red light on your card then you lose your display? Don't quote me on this but i have also heard the red light can relate to lack of power. Out of curiosity what is the spec of your machine?

*edit*

Just noticed your bit about your fan being on 0, do as others have suggested and manually adjust it and physically see if it is spinning. If not obviously there's your problem.

There is definitely enough power then, 600W is more than enough and OCZ are a good make.


Try what Skippy said and manually change the fan speed up to about 40% and watch temps.
 
just a side thought what case have you got? i had my 4850 in a small dell mATX case with poor ventialtion and it pretty much turned it into an oven with ETW taking it to about 100c let alone what something like furmark would achieve.

*edit*
Still waiting on load temperatures, try furmark or something just to rule out if it is overheating or not, or monitor it in games if you can

It's an Antec 300.

My top fan is, broken from what I can tell (Trying to replace it) so it may of been the problem.

From what I can tell it was a glitch, as it's been fine, running cool in games too (Oblivion, high settings)
