thermaltake hs killed my ti4600

[JabberWok]

I just installed a Thermaltake copper heatsink kit and now my VisionTek Xtasy GeForce4 Ti4600 won't work. Sometimes it won't boot at all, when it does boot I get vertical lines and other artifacts.

Does installing the heatsink void the warranty? Any suggestions what I might do?

Did you use too much paste, and perhaps some got on the PCB??? Try removing and cleaning the board, then re-installing it.

Its also possible that the HS is not contacting the GPU properly, causing it to overheat.

i installed the copper fan only because the ramsinks are crap. yes it does void your warranty, did u hook the fan up to powersupply directly? Did u apply the thermal paste? :p If yes to all, try using the old stock fan. Other than that, can't help ya much :)

How much thermal paste did you use? Chances are the core is not contacting the back of the heat sink and overheating. The GF4 cores are not flat.

i killed my PNY gf4 Ti4400 from bad contact with the dangerden gf4 waterblock. The card was bending slightly from the weight of the block, and the GPU wasent making good contact, so it pretty much went into meltdown, and i now get the same artifacts you mentioned, lines and random colors across my screen...=(

I did clean up the card so it looks better than new, and now im going to see if PNY will live up to their "lifetime warranty" and RMA it for me a second time.....the first time it had defective memory modules.

My GF3Ti200 chip was the same way. I ended up just putting the stock fan and thermal pad back. But, there was a thread around here somewhere (I looked but couldn't find it) where someone had put a thin circular copper plate with a dab of ASIII on both sides in the depression and then put on his own HSF combo. Supposedly, it worked out fine for him. It would be worth some extra searching to find the thread, if you are interested.
