Default Re: Swiftech Apoggee review by Robotech systemcooling

"Seems that everyone with a die should chuck it out the window."
I'll second the motion, . . . .
none that I know of have an established relationship to any CPU
IF I ever make another die it will be along the lines of Incoherent's, (and it too will have no correlation)
or a simple slug with no temp at all (temp not necessary to input heat into a system)

ms
read the Swiftech stuff carefully
Swiftech's are now device C/Ws, previously the C/Ws were case-to-air/water and included the TIM joint
Swiftech data is comparable if on the same graph, not so between graphs (different bench in almost all cases, I know for I did it)
with offsets you can daisy-chain, but with errors probably

no, that temp system is crap – agreed
but its equally crappy for all wbs, no ?
ah, the Apogee is presumed to be cooling the edges of the IHS better than the Storm ?
and it is able to do this while leaving the silicon hotter than does the Storm ?

I accept the concept of localized cooling, and understand the effect of a 'better' cooling solution on the entire cascade of temps through the system. A wb with a lower C/W will have a lower bp temp, and so forth. With a high-end bench it can be seen that the heater resistance changes with temp and this can be used to confirm the temps indicated. ANY deviation in the power/temp relationship is quite apparent and would render such a device as worthless for testing. I cannot speak for the Apogee numbers, but in testing the MCW55 similar ‘performance’ was seen – leading to the Apogee. A large number of devices were tested with the same TTV, and another for confirmation, and no anomalous behavior/results were seen.

That the Swiftech bp design is producing conflicting test bench results is clear. And so what is new ?
Why are we in a pissing contest over testing when real world anecdotal results can soon be had in all their splendid variety ?

in any case seems a pr fiasco with factual basis, not industry leadership by any means

yes Scott, such could be the case
but Lee and others seem to be saying that the 2 are similar in performance ??
so the test results are peculiar ?
I agree, but include the MCW55 with its thick bp in the evaluation of what and why
