Crippled a GeForce4 4200

i was just sittin here and i heard the GPU fan start to vibrate pretty bad. i figured i had to clean the fan shaft so i shutdown and took a look at it, and two adjacent fan blades were just gone. there was the vibration problem.

i grabbed my old Voodoo4 which has a real nice ball bearing fan and cut away some of the housing so it would perform like the GeForce fan inside the heatsink. before i put it on i thought i would put some AS3 on the GPU, cause of course the stock paste was just a waxy gunk after two years. i did a real good alcohol scubbing on the surfaces and replaced the sink with its AS3.

i powered up with the new Voodoo fan and definately felt air moving through the sink, but before i could even boot to windows i got real big vertical stripes in the posting screens. Windows now has all kinds of random globs of offcolor pixels all over the place. :(

i must have burnt the GPU. i didnt think it was a very stupid idea to try this though. am i wrong? :p
 
Make sure that the heat sink is sitting flat on top of the gpu. It could be kind of at an angle and not coming into contact with the whole surface of the gpu and overheating.

nice moitor btw
 
If the GPU was fried you would have no picture at all.
More than likely it's just too hot now. Get a better HSF for your GPU.

That fan may not be adequate to cool a newer, hotter GPU. Run out to your local store and find the gold Thermaltake HSF for video cards. They are designed for all GF4s.
 
well the artifacts havent gone away. from a very cold boot theyre there from the moment the video fades in. im pretty convinced its permanently damaged.

i forgot to mention that the GF4 fan is a 2 pin and the Voodoo is 3, so i had to pull the Voodoo's wires from the connector. i tried to run it off the card but no combination of wires to pins worked. i ended up having to run it straight off the case-fan plug on the mobo. i dont know what kind of voltage increase it got (prolly 5 -> 12v), but the thing spun very quickly and was, by far, louder than it ever was on the Voodoo card, so i know it was moving plenty of air. im sure the sink was seated just the way it was before since its held with spring retention just like on a chipset.

anyway, im back on this Voodoo4 until all these new games come out. and thats fine cause all i play right now is Quakeworld.
 
any possibility that some AS3 got on the some of the traces and shorted something out?

Correct me ifI'm wrong, but isn't the third wire just a signal wire for RPM monitoring?
 
Does your card have Tsop style memory? If it does i bet you got some AS3 in the contacts. Look for any stray AS3 on the memory pins and try to clean it out as best you can.

Not true.

GF4's dont have exposed cores, so the arctic solver most likely didnt fry it.

When do the lines start? Right from bootup? Do they stay constant? How hot is the heatsink?
 
AS3 doesn't have to be on the core. I could be on the RAM if it is TSOP RAM instead of BGA RAM like the above poster replied. The Ti4200's were made both ways.
