Eeek I’ve left this too long. Got no time now my exams are starting a week odd and works pilling up. Feel kinda guilty if im not at it 12 hours a day.

I was thinking while washing the dishes that all this vacuum stuff is a little excessive and will melt things. Surely you can do it with a standard waterblock and some thermometers.

We know the heat going to the water block (dT across it, strictly there is some heat from restriction but this can be found out using pressure drop data). We know that there is some heat going through the mobo. Ie

Qcpu = Q water block + Q mobo.

There are some implications that could be made off that.

We know wb performance on a heat die so should be able to calculate Qcpu from that using scaling calculations and its temperature as well (bare die, know interface stuff thanks to bill, know water block). Un sure need to think about this abit more.

We also know that heat is going through the mobo. If water block performance varies (vary radiator fan speed to make water inlet hotter or lower pump I’m not sure yet) we would expect more heat to via the mobo than the waterblock. We can measure this difference by using dT across the block.

VRM and heating stuff on mobo is a problem. Was thinking that we can just go linear superposition to get rid of that but my heat transfer is a little rusty.

Bit of heat transfer voodoo magic and it all should be illuminated.

(it’s a vague idea hence the vagueness of this post)
