"Cool Running" Processors ?

Thinking about getting a new MB and because the fans in the old one
drive me nuts, I'm trying to find a cool running processor; Crusoe
doesn't make MBs yet (at least none that are in a reasonable price
range), and I'm not quite geeky enough to get a PPC/Atari setup.

Is there a modern Intel offering which requires a passive heatsink only?


Can a P4 be underclocked?
and if so how far do you have to go to lose the propeller.

Can the 'M' series be shoehorned into a standard desktop motherboard ?
and is say a 1ghz equivalent to a 1ghz p4.


Thanks

It is not necessary to use the noisy heatsink fan *but* a
heatsink must be installed along with an adequate ventilation
system to force cooling air over the heatsink fins. It is the
volume of [cooling] air that is important and some very quiet
systems are built around a massive heatsink and a high-volume,
low-rpm fan directing air through noise-baffling ducting.

Also, IIRC, the "M" series do not mount into a standard ATX
desktop motherboard.

Trying to avoid fans, period. (last resort I do have a very nice 120mm
I'll install sometime on something)

sorta figured that... adapter?

Nope. Completely different architecture. However, there are in fact a
couple of companies that are making Mini-ITX boards for the Pentium M,
if that helps. Check out www.mini-itx.com for more info, e.g.:

Thanks for all your help; I still haven't decided yet, but you've given
me alot of good options, here.

Modern CPU's, AMD or Intel, are hot and need a fan.

Try googling "fanless pc" for more.

They also have some non-Intel x86 systems which might be useful. I'm
planning to use one of theirs for my next firewall.

Someone makes (used to make?) Peltier junction heatsinks for P4,
although you would be better off with P-III I would think. There were
som on Ebay this winter.

Also, you can get pizoelectric fans which move the fan noice into the
50kHz range even your bat can't hear. Try pizoelectric products Co, I
bought fans from them about 15 years ago, they may still be available.

I recently bought a pair of VIA Mini-ITX systems (one CL6000, one
ME6000, both using the Morex 2699 case) from www.logicsupply.com, and
I'm very happy with them. Much quieter than anything I've had
previously, nice and compact, not exactly supercomputer material but
hey, you can't have everything.
