After doing some testing and studying some more I totally agree with you.
Here is something I posted in another forum, I don't have the time to rewrite it so I will just paste it as it is:
I will make 2 tops available for the block, one for the mobo holes, wich will be compatible with AMD socket A processors (T-Bird, Duron and XP), intel 423, 478 (P4), 603 (XEON) and probably 604. The other top will be using the socket lugs and so far it's only compatible with socket A processors but I'm still working on it. Both tops are going to be "hard mounting", where you tighten stuff yourself, that was my idea in the beginning and I think it will be better for me to stick with it, if you are afraid of breaking your processor you should know it's not very easy to break a processor's core (I did a lot of testing on this using a XP processor that was not working, the core didn't get "crushed" until I screwed the bolt with *a lot* of force using pliers, I really think no one is capable of applying this kind of pressure on a bolt by hand. Also the contact boint between the block and the bolt will be larger than the bolt itself, maybe it will have a thin hard rubber sheet to prevent the block from sliding, it will also be right on top of the core. Some people told me that springs would help on distributing even pressure but thinking about it, springs may decrease pressure, as they probably can't put as much pressure as a large bolt, making the heat exchange a lot worst.
about the bios thing, that's the kind of smart and simple thing we usually don't think about
really good idea
Thanks
