Direct die cooling helps overclock

post #1 of 7
Thread Starter 
Hi guys, I did a test about direct die cooling. The thread is here:
http://www.overclock.net/t/1406604/direct-die-cooling-water-block/0_50

It shows the core temps are lowed quite a bit. Since IB and Haswell is so much temperature limited for overclock. Any improvement on temps is good. Check the details and feel free to comment:D

But how do we know that how tight to fit the sink before crushing it?

I had always though every one who de lidded when direct to die, then realised they ere keeping the IHS and using two applications of better thermal past, if i had an Intel machine like that i wouldn't even waste my time i'd mod it for direct to die. then again that's me.

Plus with haswell its more riskier due to those caps on the PCB. A good chance of short circuiting stuff quite easily.

There is no clear gauge on how much torque you should apply. I would say about 10-15lbs each spring/screw. The springs included in commercial waterblocks gives about 15-20lb max each when completely compressed. This much force is no where near crushing the silicon if the pressure is even on die surface. However the threshold of cracking becomes much less when mounting is not flat, when one corner of the silicon die takes all the forces. It only takes a few lbs to crush a corner.

Rule of thumb for mounting direct die:
1. Try to mount the heatsink as flat as possible and always use "figure 8" method to tighten screws/springs and only tighten quarter/half turn each time.
2. Never fully compress the springs. The mounting force will increase enormously after springs are fully compressed.
3. Too little pressure is also bad, which may cause poor pin contact in the socket. Normally I tighten the springs to 2/3 or 3/4 of the amount of full compression.
4. Use electrical tape to protect the CPU PCB surface from short circuiting. But never build tape higher than the die (for example don't put tape over the surface mount caps on Haswell cpu).
5. Center your heatsink/waterblock with respect to the die/mounting holes. Off-center mounting will cause tilting of the heatsink.

Even with this procedure I think this is still chance of damage since we are human. Think about the risk and gain before you practice biggrin.gif

You are right. Those caps are almost as high as the die. Even with a slight tilt the heatsink will short them out. It is very crucial to center the sink on the die so it wont tilt during tightening.

I think I'll just stick to the IHS as it wont be a worlds difference when using CLU.
