Thought this was interesting enough to start a thread ;)

"Above temperatures of 150 degrees Celsius, chips break down faster and the results they produce become unreliable. At 200 degrees Celsius, they cease to function."

Gawd, we thought we had seen some extreme temps with overclocking...but THAT is too much...150 Celsius???
OUCH...:eek:

Thanks for the link, SSS...interesting article...

Pretty interesting, but if you read carefully, they mention that the liquid spraying method only removes 20 watts of heat. I don't think that will come close to the methods we use to cool our oced cpu's. But who knows how far they'll be able to push it. Now we'll have to think of a new way of insulating the mobo :D

is this like what they use to cool heavy psi turbos , sides an intercooler

when you go over 100c i imagine using water sprayed on the chips gets a lot more effective...

hmm.. too bad cpu's don't work that high, you could have phase change cooling with water instead of some refrigants..

For example, Brown said, in a 60-watt radio frequency power amplifier, spray-cooling disburses about 20 watts of heat.

Oooh, I think they need to visit us!! I wish my XP2100+ were only 60 watts, and it would survive if I only removed 20 of 'em...I could watercool with 1/4" lines and a thumb-sized pump...wouldn't that clean up the case some!

It is neat tech, Sam. Thanks for the link. But to me, it takes thousands of dollars in (our) grant money for some government/college schmo to get within 25% of what we do everytime we fire up the computer (and then pat themselves on the back for being so darned intelligent). Think I could get a grant too, and blow them away? I think a Cooljag and some AS adhesive could do 20 watts on an IGBT too, without custom machined nozzles too. Prolly save about 80% of the budget.
