Still, just to be on the safe side...

My board has a piece that sticks out almost a quarter inch in the center. The plastic plate seems to be made out of a very strong composite and has a pretty good pressure distribution design.

The screws cost me 18 cents at the local hardware store. If all else fails I might consider the custom plate but as it is at finger tight I really don't see a reason to warrant the risk, though you're right, with the foam it would probably be nominal.

Well, that was fun! Thanks for the help and suggestions.

Incidentally, I recommend having a 90 degree angle philips as finger "tight" with the standard K8 isn't really possible since its screws and not the nuts.

Also, a relatively thin layer on the heatsink as suggested as well as a similar distribution on the chip seems to be the best with Arctic Silver. I used a razor to achieve an even spread and stayed maybe a quarter inch away from the edges on the chip.

Absolutely awesome! This thing is like an iceberg when combined with Arctic Silver 5. My Athlon 64 3700+ is rock stable so far at 2.75ghz (stock is 2.2), 250fsb x11, HT x4 at 1000mhz, 166 memory divider DDR at 200mhz, and 1.55v CPU core...

26c - 29c idle and just 35c - 37c full load after 15 minutes of SuperPi!

I might decide to push it higher depending on how things turn out, however right now I'm happy with the marks I've been getting.

Those are some nice temps. I get about the same idle but my load is about 10 degree's higher - I'm gunna sort that out though. Im running at the same voltage as you, so I think I haven't tightened it properly - the base still shifts about.

Interesting. I would recommend getting an even layer of Arctic Silver 5 distributed over the base of both the processor and the heatsink prior to installation. Use a razor to smooth it flat. In terms of how much to use, I found that accounting for the thickness of the stock fan's patch of heat transfer is a good reference. I'd say probably a BB or two worth on both the processor and heatsink, but then others seem to recommend less. I can say from experience however that it doesn't squish out, being highly viscous, and relying on the pressure to spread this sort of thick putty around is simply not going to be sufficient.

Also, when tightening make certain not to overdue it. If the fastening metal plate you lay over the top of the BT starts to bend at all you've gone too far. Also, keep an eye on the motherboard itself as you tighten, making sure there is no warping whatsoever as this will tend to damage circuitry. When installed optimally it will still shift a little under hand pressure twisting it a bit, but not much, and should slide very slowly given the AC5 layer.
