P4 Xeon operational temperature range

P4 Xeon operational temperature range

[Andrew Walrond]

Does anybody know off the top of their head the max tempature at which I 
can expect a P4 Xeon to operate ?

TIA Andrew

For example
	http://www.intel.com/design/xeon/datashts/290740.htm
page 89 lists ranges of 75-78 depending on core freq.

I only found one chip that went above 78C (81C) but didn't delve into 
which it was.

Intel website has crappy navigation, but at least the info is there. :)

depends on the PIV version,

latest 0.13 micron has a maximum temperature of 69 degrees, but if you are going
under full load over the 50/55 start to be worried.

Luigi

p.s.
For AThlon AMD talks about 95 degrees, but
you should ttry not to go over the 60...

Hmmm. This is a dual xeon 2.6 blade in a very tight cluster and seems to 
hovering around 55C. I had a couple strange crashes and wonder if this 
might be the cause I'm unwilling to blame 2.5 ;)

Can anybody recommend a good 1u cooler assembly for socket 603 ?

Re: P4 Xeon operational temperature range

[venom]

which 1u case are you using?

as important as the CPU coolers are the fan used for fresh air circulation.

Its a bunch of 10u custom cases each containing 10 dual xeon m/b's 
mounted vertically. Air is ducted between the blades and over the heat 
sinks, but I think a thin (hence 1u) heatsink fan combo might help.
