    Mosfet heatsinks on P4C800 - Anyone?

    I've notice the mosfets on the P4C are much smaller than say an IC7. I've been looking at the microcool sinks over at sidewindercomputers and was wondering has anyone tried these on an Asus board. If so pics?

    I didn't use those particular sinks for my FETs, but I do have sinks on all of my board's FETs + southbridge + clock generator. I just cut up a stock Intel heatsink with a hack saw. Here's some pics if it helps at all:

    Nice job Tio!!!! I have 2 of the Asus stock n/b heatsinks and was thinking of doing the same thing to the s/b. This is a lot cheaper than the microcool sinks.

    Did you use thermal epoxy? Have you noticed any improvement?

    thanks. Yes, I used Arctic Silver Epoxy to attatch it. In terms of overclocking, no, I haven't noticed an improvement. However, if I turn off my case fans for a while, that heatsink on the south bridge (and the rest of them for that matter) gets HOT, so I figure it can't hurt.

    Just so im sure, you have to take off the thermal tape on the microcool sinks to use the epoxy, right?

    Yup, thanks to Tio's inspiration, I took some ocz copper bga ramsinks and removed the thermal tape and applied artic silver epoxy, they work like a dream.

    Wish I could, but it's the chip holding me back. I did 3.7 once running dual primes with Short and Blend tests, but Short and Large always fails under 30 minutes. I've even tried dividers so I know it's not ram.

    I'm debating a 3.4C or 3.2E to hit the elusive 3.7-3.8 but my current 3.2C just doesn't have what it takes, no matter how many volts I through at it.
