Stock Intel Heatsink, What temps can it handle?

[nowwhatnapster]

I have a couple of stock intel HSF's here for 775 cpu's. I noticed that some are thicker... than others. like 1 inch vs 0.5 inches. So they clearly manufacture these things for different CPU's and speeds.

My question is what CPU speeds/cores are these different heatsinks rated for?

Haven't been able to find any info on google, maybe i just suck at keywords.

I'm sure the thin one can handle all the celeron single cores, and the larger one is probobly for dual or quad, but I would prefer to see some documentation.

From what I've seen, the 65nm parts (both duo and quad) have the best stock heatsinks. The 45nm have thinner heatsinks, and again, it doesn't seem to matter whether it is a duo or a quad. The extreme edition chips had a larger still heatsink for a while, though I'm not sure of the details of which ones had that one.

Did some more googling it appears these thin ones are good for

The Intel® Core™2 Duo processor E8000, E7000 series, and Intel® Pentium dual-core
processor E5000 series require a thermal solution equivalent to the E18764-001
reference design; see Figure 6-1 for an exploded view of this reference design.

the E18764-001 i got off the heatsink. found the info in a PDF dated October 2008

Good to know! Didnt think this little thing could handle a wolfdale

Yep - the Wolfdales are surprisingly low power and heat. I think the E8500 is something like 34 watts full load at stock clocks.
