Do P4s stay cooler because they have a heatspreader?

they ensure that the cpu contact area is greater, this can help in cooling if the core / heatsink bottom are not parallel to each other. Personally I dont think much of IHS they are just another layer which can obstruct the flow of heat to the heatsink but they are a good safety net.
 
I think P4 Northwoods run with less voltage by default relative to Athlons. But I could be wrong.

If so then maybe the Athlon 64 (which also has a heat spreader) will run cooler then the current small core Athlon XPs do.

No... I removed a HS from my last P4 and dropped full load temps by 8c.

Wow.
 
I removed my IHS on my 2.4B and it did drop the temps a bit....they are made out of copper...but tin plated..I usually sand through all the tin plating.

I believe the P4 die is bigger, so there is more surface area for the heat to dissipate from.
The P4's have more die for one thing, so that gives more transistors therefore larger die area, and the thermal dissipation (wattage) is similar to Athlons, so they are cooler.

The heatspreader is, in some ways, a good idea, as it reduces the chance of damaging the core when a heatsink is put on the processor. The heat increase isn't that much, since it runs cool anyway.
Feel free to correct me.

AMD person I presume?

I'm sure someone has a link to an article on how to do it but from what I've seen the best way is to freeze it to brittle up the thermal epoxy a bit and then work a razor blade around the edges of the chip very slowly until it pops loose. I'm looking to get a 2.53 or a 2.4 in the next week or so and I think after I get it I'll try to remove the IHS from my 1.6a and see what I come up with.
 
thats called a heatspreader

As I had the P4M1.4 in my hand yesterday I think I can safely say its big in comparison to the t'bred. The squareness of the die helps for stability as well which is a factor when mounting a heatsink correctly.
