ATI 3850 Anyone Else Have This Problem?

[Tom56]

I recently installed a Sapphire Radeon HD 3850 video card and while it works fine for it's intended purpose, the fan is quiet loud most of the time and it has a tendency to run fast then almost stop,then run and stop then it will run for a while and this waivering goes on which is annoying. This happens while there is zero screen activity and I would think if no activity the fan should not be required at all. When a load is put on the video card the fan will run continously as it should. I have it set in overdrive and used Auto-tune to set the best settings which are GPU 739MHz and Memeory Clock 939MHz. Has anyone else experienced similar situation? Is there a card issue here that I should address with the local store or ATI? As always, thanks for your replies.

My Asus 3850 doesn't do this. Very quiet and no ususual start/stop patterns.

I have a similar problem with my older 7800gt. It runs quiet almost all the time but when I put my PC into sleep and wake it the fan can't make up its mind. Its slow then fast back and forth until I get so annoyed that I have to reboot. Does yours do it after being put into sleep mode too? or are there different circumstances?

Planefreak. I was in Ubuntu and then restarted back to Windows and then the video card fan started the waivering. I shut the thing off and went out for a while and when I came back started it up again, the fan ran at one speed. I must admit this fan is not very quite. Before I installed it my unit was very quiet and now I have this rather loud fan alwys running. I would have thought if there was not screen activity the fan wouldn't run at all. I may contact the makers of this unit and see if there is an issue with my card. At zero screen activity the temaperature of the viseo card is about 41C which I think is quite good. I just wish the thing ran quieter.
