I've heard a lot about asus probe telling the wrong temps on this board. Is it the thermistor or is it the program. My copy seems to agree with the bios and MBM except for one time were it was 10 degrees hotter. The reason why I ask this is because I rally don't see too cool of temp readings from my board. I have used a PEP66 with many combinations of fans, I have tried making an alimunum waterjacket out of an old heat sink. Now I have a copper "cross" drilled waterblock and I still seldom see less than 42 degrees. My pep just couldn't keep it under 50 @ 1.89v. I have lapped all of the above AND my CPU. The copper one was lapped untill I had a tiny little mirror. I even used arctic silver in the final stage of sanding. I am using a THIN coat of silver. I just don't know what else I can do. I am in the process of building a bong, but I really don't have too high of hopes for much less than 40 degrees.

When I first started up with the new waterblock It said 35 degrees, but within 5 minutes of SETI running in the backgroud it broke 40 and soon went up to 43 finally stabalizing at 45. The highest I've seen from it id 46 after some gaming.

BTW I have a duron 700 @ 1000 - 7x143

Your not alone here, I gained some gray hairs dealing with my A7V133. I ran 5-6 experiments on a closed case setup and without going into detail my conclusion is that the diode sensor inside the socket seems to report temps ~7-10 degrees Celcius above actual temperature. From what I gather from most people that own this board, everyones experience is slightly different. I'd would be shocked to find someone that has this board, that the temp is actually close to correct (in the bios or Asus Probe).

I forgot to mention, that the readings seem to be more acurate when ambient room temp is below 70 deg. F.

That makes sense because it seems like the comupter is more sensitive to ambient than I am! Heh. Thanks for the reply. I feel a lot better now. It just pisses me off that I was panicing when I was over 50 with the pep

With this in mind... How can I add a temp sensor that actually works. I know that the way they test the heat sinks is to put a sensor on the die, but doesn't this cut down the real contact area of the cooler? Pluss I have a waterway that would be right there. I've also heard of people laying the across the cpu (under the cooler), but I have a shim on mine because my waterblock can double as a dumbell. Could I cut a chanell out of the shim to do this method without too much risk? Where can I get a decent (better than the asus) temp sensor to do this with (locally, I don't want to send away for a compu nurse). Any help would be great.

I have an A7V, A7V133, and 2 KT7A-R's. I have tested the same cpu and HSF on all 4 boards and the Asus reads a good 10C hotter then the Abit boards. Abit has a thermistor that you can bend up so that it touches the cpu. Asus puts their's on the bottom of the socket so what you are really reading is the air temp in the socket with some influences from the mobo temp. This is crazy and there is no way a reading from this kind of setup can be correct. Asus should do something about the way their boards read temps.

I wouldn't worry about it to much as long as your system is stable and doesn't show signs of overheating and you have the HSF installed properly you should be fine.

Thanks... But it's not about that for me. I probably spend more time making thing for my computer to make it run cooler than I do actually using it. I guess it's a hobby. I just wish I could compare more accurately with other people.
