For those of you who have wondered how you could do video card waterblock testing, I have found a way. Atleast a way for the X800, although the same sort of idea should work with any video card that has an ondie diode for reading temps.

This idea came to me when i was looking through EVEREST and found that it was reading the temp through a chip called the National Semiconductor LM63. So i googled it and found the PDF file on it. I then noticed that it read diode temps MUCH like the way that is done on Athlon XP's. So i looked through the PDF a little more and found where the hook ups fo the anode and cathode are on the chip.

So all that needs to be done is to solder two leads to the chip on the x800 (or whatever board and chip you happen to have) and then use a higher quality diode reader. Myself, I will be using the same maxim eval board that pH uses which is very good as it has multiple hook up points so i can get accurat readings from both the cpu and gpu.

Here is a picture of the chip and the hook up points for it on the x800
