GeForce 4 fan voltage mod

[godmare]

I have a BFG Tech Asylum - GeForce 4 ti4200
The fan power is a 2 wire lead to a header on the card, I guess that's 12 volts...?
Is there any way to lower the voltage to the fan?

Gotta bump this to stay on the first page 🙂
Anybody? Do I need to get an adapter to a 4-pin molex connector?

Hey did you o/c your vid card? I have the same card and I want to o/c it, but I don't know how far to go using only stock cooling.

No, I don't have it regularly overclocked.
I've never actually overclocked the gpu at all, just the memory because it's slower than a 64MB card.
I have Thermaltake ramsinks on the chips and have had it at 500mhz no problem.

Cut one of the two wires, and insert a resistor in there. That will reduce the voltage the fan recieves, depending on which resistors you use. Otherwise, cut the neg wire (usually the black one) and splice and connect to the 5V wire from you PSU.

Okay, what I've done is wired the fan header to a 4-pin molex and 7 volted it right from the power supply. I had hoped for a cleaner connection, but this works 🙂
Thanks for your suggestions, Ouloat, I may yet look into a resistor on the line.

How much are ram sinks? And do you know how far I can o/c it w/o ram sinks?

I got mine at CompUSA with the Thermaltake GeForce 4 copper HSF (which I am not using, since the damn stocker is epoxied on) for about $12. Last I saw it, it was $16. They also carry either aluminum or chrome plated (not sure which) Themaltake ramsinks packaged seperately for about the same price.
Also, the 4-piece Thermaltake ramsinks in question line up perpendicularly to the ram chips on the card, but you can cut the sinks in half, yielding a top and a bottom for each chip, with a Dremel, enabling proper orientation.
