I understand what you're saying nikhsub1, but my question is: how fast would that difference show up on the CPU?
If it takes say, 60 seconds for the CPU temp to drop by 0.5 deg C, just like the coolant, then as long as my cooling solution doesn't vary by more than 0.5 deg C per minute, I won't see a difference, and I have that parameter for the cooling solution.
I just used the Cascade as an example, because if it's the best performing block, then it's more than likely to allow that temp change over the shortest period of time. This is where direct die cooling comes in handy, because it can give us some pretty interesting data, even if the application isn't practical.
On the other hand, if we use a heat die, and it's made of copper, then that fluctuation may be more dramatic.
But again, I have no test data.:shrug:
(BTW, congrats on the silver Cascade
