wouldnt it be great if Mobo makers started to suport reads from the cpu internal diode
It sure would, so many try, a few get close to correct,
I use a flat thermistor under the waterblock, just need a little measuring before assembly, I work out where the probe is to be placed, then put a small distance mark on the cable to line up with the edge of the socket, after the block is fitted I then bend the probe slightly in two places so as it's fed between the cpu and block it contacts the bottom of the block, then when the mark on the cable lines up the probe should be touching the core right where it contacts the block, reads a couple of degrees higher than being taped onto the cpu, plus no risk of crushing the probe or compromising the fit of the waterblock.
Have tested the probe with a "half speed test" similar to the one on the As3 site, and is good to within 1c, still not the true reading of the internal core temp aka intel chips but more reliable than most "on die" temps on Amd boards and given the correct amount of thermal paste should be very close to the top of the core temps.
The Digitaldoc5 has fairly accurate readings but can fluctuate with voltage changes, so for Cpu, water and rad temps I use a Senfu thermometer (battery powered) with a rotary switch selecting up to six probes.
