X850 PRO Fan Not Spinning!

[quadomatic]

I've noticed that there is something seriously wrong with my Video Card and it's fan!

I've been playing various games and finding that after some time, the monitor stops receiving a signal from the video card. I checked the card and found that there were a lot of artifacts coming up. So, I uninstalled the ATI drivers, used Driver Cleaner, and then installed the Omega drivers. I then set the fan speed to 100% in ATI Tray Tools and ATITool, and to have it always run at that speed.

I started playing a game, and after maybe 15 minutes, I noticed that the fan stopped running at 100%. I checked ATITool, and it said the card was at 121 degrees Celsius! The fan started spinning at 100% after I closed the game, and the card has now cooled down to 73 degrees.

It seems like something is wrong with the fan control on the card. Can someone help me out and tell me what I should do?

It's a Sapphire Radeon X850 PRO PCI-Express with 256MB of ram. It IS NOT overclocked. The rest of the specs are:

A64 3300+ (Socket 754, no overclock)
Biostar nForce 4 Motherboard
ULTRA 400W PSU
Western Digital 160GB Hard Drive
16x AOpen DVD Burner
768 MB of Ram

It might help if I let you know this...I recently had a power surge that destroyed my power supply. I replaced it, and now it works okay. I noticed the CPU Fan had started dying after the power surge (it may have been dying before, my PC had been crashing in games before), leaving my processor running at very high temperatures, so I had to replace that too. There is an occasional ringing noise coming from the system. It's been happening since after I replaced the power supply since the power surge. It's a very high frequency noise, and I know this for sure, because my parents aren't able to hear it. Nothing is wrong with the hard drive, so I know thats not the cause of the noise. I think the PSU might be making the noise though.

can't anyone help me?

You can try simply investing $15 - $20 on an el cheapo HSF for the X800 and see if that will work but it's prob too little too late now.

#1. A $10 surge protector is a very good investment for a several hundred dollar PC to prevent this in the first place.

#2. Sounds like it's time to look at an upgrade as problems like yours only get worse after a power surge like that. Your video card, mobo and possibly CPU will more than likely fail on u completely within a few weeks/months now.

#3. Put a heavy steel toe'd boot on and kick yourself repeatedly for not buying a surge protector or better yet have a friend kick you repeatedly with a heavy steel toe'd boot while kicking yourself with the other boot.

If you're concerned about temperatures and haven't reveiced a new cooler yet, you can always open the case and run a 12 inch fan blowing directly inside your computer.

I have a 940 watt batter backup for my two computers. (Tripp-Lite Omni VS 1500) UPS have a built-in power surge protector and should not be used with surge protectors.

I really don't know what to say. If I were you, I'd 1) get a surge protector and 2) do the 12 inch fan thing. After that I'd just use it until it's used up, and get a new comp after it breaks. You might want to backup your important data though.

I'm not sure about ATI cards, but you may be able to make a modified BIOS that will keep that fan at 100% all the time. That might be more reliable than ATItool and such.

i vote for number 3 !

are your case fans still working?

 

[quadomatic]

Right now, I have no case fans plugged in. My case is just open right now. Everything else in my pc appears to be working fine, and has been working fine, except my video card's fan. This problem only became apparent after the CPU fan was replaced.

It's strange, because the fan ONLY stops spinning in games, and stops after maybe 20 minutes into a game, like CS: Source for example. The very second I close the game, the fan starts spinning like normal.

I think I'll just replace the fan on the video card now...does anyone have any recommendations for a hsf to replace it with? I wanted an Accelero S2, but there are not places that stock it, and then Accelero X-series ones aren't compatible with my video card.

Is it possible the video card's fan controller is broken, and I would need a fan that plugs directly into the power supply? How would I go about doing that? Are there fans that will do that?

I tried the 6.9 catalyst drivers, and the fan still had problems. I tried ATITool and decided to keep the 3D view open and watch the temperature monitor and stuck my hand under the fan of my video card.

The hotter the card got, the more it seemed like the fan was slowing down, like it was under too much stress. Once it reached 100 degrees Celsius, the fan stopped spinning. I closed the 3D view, and immediately, the fan started spinning at full speed.

I guess I'll try flashing the BIOS with it edited to have the fan running at 100%...but I don't see how that will fix anything.

Any other ideas?
