Cascade and K8 ?

[EluSiOn]

How well Cascade will perform on K8 CPU?

I remember Cathar said something about P4 IHS will serve as an obstacle preventing the heat quickly tranfer from cpu die to the waterblock. So with IHS on, Cascade will perform just like WW, and nikhsub1 said if IHS is removed, the temp probably will drop 4c, is that also true for K8?

in addition, has anyone succeed removing K8's IHS?

i dont think that any waterblock would do much better than another when operating with a heatspreader. and you should be able to remove the IHS unless its like the prescott and soldered on.

couldn't find anything on people removing the IHS on K8.. read a little in proforums and .. i donno.. maybe this will help you

drill through IHS

i think that thread is too much for me....

my basic question is still remain... am I better off to remove the IHS on K8 using Cascade? if so... how do I procceed removing a K8 IHS?

 

[Korndog]

i'd try it the same way as a p4 IHS

but keep in mind that amd might have soldered their core/ihs together like recent P4s...

Any waterblock works better to cool a CPU without the IHS. The Cascade should give great temperatures either way. If you remove the IHS, it's not specifically because the Cascade requires you to, it's because the IHS "adds" about 4-6C to the CPU's temperature, and this is true for many cooling solutions, and not specific to the Cascade.

ok... i guess... intel and amd is being a dumbass buy putting on those IHS.....

Would I be able to use the current cascade mounting holes for a K8, or would I need an adapter?

You need the adapter. Cathar has them, they are aluminum top plates that will suit a P4 and a K8.

No, they are making it harder to crack the core, which reduces the amount o fRMA's they get.

It's a smart move. The heat of a P4/A64 is still concentrated in the middle of the heatspreader, so the cascade/WW still cools the right spot.

exactly, the reason you get lesser performance is because of the added TIM joint (though maybe this is less of an issue now that there is apparently a better joint, but we have little information on this as of yet, and it is still a TIM joint), and the fact that the added 1.5mm copper thickness defeats much of the design of the cascade/WW/RBX/thin-base-blocks.

As a matter of fact, the IHS, despite its name, has nothing to do with "spreading heat". It is to protect the core, and that is all. There is an overclockers article that illustrates the point that all the heat from a P4 core is still concentrated on the area of the die.

here it is
