I went to my local computer shop to look for a fan to put on my upcoming card, a Voodoo3 2000 AGP. The one he gave me is a Cooler Master 38mm fan @12v. Is this enough to cool down the GPU, even just a little, and could I try to overclock the card to, say, 175 MHz stable? I plan to fix it on the heatsink, without removing it.

Thanks!
