Pentium 4 Gets A New Socket. Continued
Below you find a picture of Intel's reference Socket478 motherboard with i850 chipset.
You can see the new cooler retention mechanism which unfortunately requires new coolers as well.
This might be a nuisance for current P4-owners who are looking into an upgrade, but it shows how serious Intel is taking the job of providing a sensible cooling solution for Pentium 4 with a safe and easy retention mechanism.
I wish AMD would take an example and come up with a better solution for their processors.
