Can anybody suggest a way to remove the fan/heatsink from my videocard ?

It is a Visiontek Xtasy GF4 Ti 4200. The fan itself is held in by three small screws. The heatsink seems to be mounted directly to the GPU with some sort of really fierce double sided thermal tape. The fan intermittently makes a groaning sound, and I'd like to replace it before it goes completely bad. I bought a G4 cooler from Thermaltake, but I can't install it with the stock heatsink in place.

Any suggestions ?

You can by replacement a heatsink/fan for these cards for around $20 Canadian.

My suggestion is often these little fans run dry of lubricant and can be fixed up with one or two drops of 3 & 1 oil.

To add oil remove the fan and remove the sticker from fan center, then add oil at bearing end of fan. Will most likely have a dust cover and look like a metal guard touching the shaft on the bearing end.

They are mounted with tape. I find Goo Gone works well in removing glues and tape paste and then cleaning up with preferably 99.9% alcohol if you wind up replacing the fan/heatsink unit.

Thanks for the advice.

Thermaltake sells a unit called G4-VGA Copper Cooler (places like Comp-USA) for about $20 US also.

Will Goo Gone damage anything on the card ? I'm not very anxious to soak an expensive PLASTIC component in a solvent that could damage it. I would prefer another way if anybody has ever done it.

I would try to cut or pry it off, but the adhesive is quite thin, and I'm afraid that a blade might damage the GPU. Also, I don't know how strong the BGA setup is, but I'd hate to pull it apart by accident.

Any help is appreciated.

just to add, i use acetone to remove the old heatsink. you can use a q-tip to soak the edges, then gently pry them apart when the glue is softened up. then clean the chip up with acetone, and attach the new one to the chip. use gloves as acetone isn't gentle with your skin.

acetone is a high caustic. try a non acetone based fingernail polish remover as this won't affect the epoxy resin (plastic) base of the BGA.
