Cooling experts out there, some help please

[alvin at Mail.Linux-Consulting.com]

hi Kevin

I know of some heatsink and fan vendors....
( dont have any finite element apps to show cooling

the intel i810 based chipsets does support i2c to be able
to read the cpu temperature, voltages and fan speed
( motherboard health monitoring )
	- we did quite a few experiments with it
	-
	- turned out that the smaller the heatsink, the
	- better the cooling was .. a small fan can only
	- cool so much metal of the heatsink

the Electronics Cooling magazine is a good starting point
of heatsink/fan info ...

if you're not restricted to1U systems... the generic
heatsink that comes with the intel CPU should work fine

if you're trying to fit Intels P3-866Mhz or p4-1.4GHz
machines into the 1U cases.... we have problems with
cooling the P4 and all 1U vendors have to customize
the chassis for the P4 and AMD motherboards
 
thanx
