Proc heatspreaders Vs Evap Heads

[K404]

Just a quick question, kind of in regard to my paranoia...

The integrated heatspreaders on the current A64s and LGA775`s are...3cm square-ish. The contact plate on the evap head (on a Vapo PE anyway) is smaller than this, by maybe 20%. Is this anything to worry about? Is the core of an A64 or LGA775 still the same size as on Athlon Xp`s etc, so most of the heat will still be concentrated there, under the evap contact?

It is nothing to worry about, as shown on there you can get gains of temp, often with phase change this makes little difference to the overall overclock.

Have to say i dont see the point of remounting the IHS after taking it off, might as well remove the inefficient thermal transfers completely if you are going to go for it.

If you do remove the IHS do make sure that you are getting contact as the core sits lower than the IHS would, and on phase change make sure to fill any air pockets with dielectric grease so that none of the bits surrounding the core get condensation on them.

Be aware that on certain families of chips the IHS has been epoxied down and so you cannot remove the IHS without ripping off some of the core with it

im gunna do this when i re-tube my comp. If it really dopes reduce temps by 3-4°c and its free to do it. Considering we pay £40-£160 for water blocks i.e. dd tdx for £40 to £160 for cathers g5 it seams like a good idea!

LOL.... I wasnt seriously thinking of taking off the IHS... i`m not that insane! anyway.... bye-bye resale even if I dont break it...

Was just wondering about % contact seeing as pelts are (I hear) fussy bout that.

i aint joking abouttaking it off, when i get my new g5 cather block off phil and i get my proc out ill do it and see if tehre is any reduction of temps

Fair enough. "extreme" is part of the site name- thats what I thik that mod is. Ah well... R+D kudos to ya.

I personally wouldn't advise taking the IHS off, the cores are much more delicate than the old xp's but its your cpu

Gutsy move - let us know how it goes!

i will when i do it dont worry ill take my time and take pics too so i can proove it!
