Just a tip to share

Hi all.  I thought I'd just share a tip with everyone regarding an experiment that I did last week with my video card and see if anyone else has tried this.    
I have an ATI 8500 graphics card with an attached fan that has been dying over the last couple of months.  The fan on the card was making a lot of noise and the speed/noise was fluctuating up and down.   The card is about a year and half old, so the the retail warranty was up.  However, there was a manuafacturers warranty of 3 years.   I checked into it and realized that I'd have to pull the card, send it via courier to ATI and wait probably a few weeks before they delivered it back (repaired, hopefully - they didn't actually say they would repair, just send it in to them).
I didn't want to be without the card that long, so I decided to do the following:
- I unscrewed the fan from the heat sink on the card and removed it.  The power for this fan was right on the card.
- carefully popped off the heatsink from the chip (it was glued on)
- cleaned the top of the heatsink with some solvent I had lying around.
- right in the middle, (about 2 cm square) put on a dab of thermal paste right that I got for free from a local shop
- put a drop of crazy glue (which I also had) on each of the 4 corners of the chip
- pressed on a heatsink/fan combo that I had leftover from on old 486 machine (I have a box full of free parts.  it was just the right size with a completely flat heatsink bottom - no ridges or lips of any kind) and waited for the crazy glue to set up.
- plugged in the new fan into one of the power leads from the power supply.  

It works perfectly!   The fan has essentially 0 DB sound but pushes a lot of air.  It used to be quite hot on the backside of the card, but with this new fan/heat sink, I can now just barely feel any kind of heat, even after an intense gaming session.  (it's quite a bit bigger that the original heatsink)  

Has anyone else done this sort of "fix" to their card?

cheers

Ha!   The slot1 heatsink must have looked cool on the card!  How did you mount it on the card?  Crazy glue?
I guess that the manufacturer doesn't put in a bigger heatsink/fan because the one I put on interferes with the closest PCI slot.

That's good to know.   ATI even refused to discuss the problem without the video card in their hands.  I also would have had to pay for shipping both ways.

Well... sort of, I couldn't use two of my PCI slots anymore, but it was surely fun to show people my videocard cooler was bigger than my CPU cooler.

Epoxy :o) a very thin layer.

Interesting to know that.  I was wondering if an epoxy would be a heat barrier or not.

I've got two 80mm fans (one in front <in> and one in the rear <out>) right now which seems to do a great job of moving the hot air out of the case.

In fact, epoxy transfers heat pretty good, of course, not as good as thermal paste, but with a heatsink that big I wasn't worried too much. (and it's always fun to try such things with old dust collecting hardware, if it starts smoking... hmm... too bad) I never even considered doing this on my nice Wildcat 4 7210
