the sk7 vs the slk800...

[treepop]

...how much better is the slk800 over the sk7..and also where can I find the illusive sk7?
EDIT: How much is a good deal for this heatsink?

I've never owned an sk-7 so I can't vouche from experience. But from this article http://www.overclockers.com/articles373/ the slk-800 would be probably around 2-3 degrees celcius cooler.

www.svc.com has a sale on the sk-7 right now.

Anyone know exactly why the SK-7 performs worse even though it apparently has greater surface area and the same basic design?

it doesnt have the same surface area does it?. surly it cant, its not nearly as big as the slk-800. Also, the smaller base on the '800 helps - dissipates heat quicker.

On an AMD the SLK-800 will deifinately beat the SK7 by 3c or more depending on how much you oc.
On an Intel cpu the SK7 might actually beat the SLK-800 by a few degress because the SLK doesn't cover the entire IHS while the SK7 does. I have read quite a few posts here about the SLK-800 and 900 performing poorly on the P4.

Look at the bottom of the two heatsinks. The SLK-800 has a very open bottom compared to the SK-7, which allows more air to flow through the heatsink. And, of course, more air means better cooling.
