Watercooling & C/W ratio

...the lonely world of a engineering geek .

ANYONE HERE DOES ANY MATHS?

Ha ha don't take that to heart -you fellas don't need to mess with that unless you want super-accurate temperatures (but what for?) and the conclusion is: Just let it run; if your CPU does melt or hang up, then the C/W is low enough already. Only god knows whether you should have spend that extra pocketmoney on a Glaciator rather than on DIY stuff to cobble together a mist puffer.

I meant 'doesn't melt or hang up'.... typos, sheesh! What is the world coming to?

To measure basic the C/W of a water cooled setup three points on interest must measured. CPU temp, intake water temp to the CPU's HS and exhaust of the CPU's HS. These three points will allow you to figure the effeciency (C/W) of the whole system and that of the water cooler system itself.

Exhaust water temp and cpu temp to calculate the C/W of the whole and intake and exhaust temps to calculate the water cooler system itself.

Adding more, like previously stated will allow you to measure specific areas of interest, but to anyone other than a thermal dynamicist it's not worth going to the trouble of.

You only need two temps for any component: one for the heat source and the other for the heat sink -not a HSF! And it's the fresh water or fresh air, a place where the waste heat gets dumped. You don't need to measure the temp of the exhaust anywhere unless it is the intake of another component (another heat source) of interest.

Ah, common sense escapes my brain... you DO need to measure the exhaust fluid temp if you do not know the heat being thrown away by the heat source (q). Normally one can find it out from Radiate and that amount of heat is the same throughout a WC rig at steady state temperatures. So, again, deltaT/q=C/W.

eYup
