Bill I think he is under the (misguided) impression that you are affiliated with ProCooling.

Kinda funny considering the past between you and Joe (Kelly).

Since I know you are reading this Steve, DO check that SMSC pdf. It is from a reputable mfger and discusses the many problems with getting reliable numbers from a diode. Look at this one too:

http://pdfserv.maxim-ic.com/arpdf/MAX6657-MAX6659.pdf (page4 remote temperature error vs. remote-diode temperature).

Note that the temperature range of interest affects the error involved.

Consider the precautions ic mfgrs suggest taking to avoid serious problems in the numbers produced. Now consider that motherboard mfgrs do NOT take such precautions.

Nevin at Arctic Silver has some comments of relevance:

More info on diodes can be found here from AMD and Intel:

http://www.amd.com/us-en/assets/cont...docs/24309.pdf

http://www.intel.com/technology/itj/.../pdf/art_4.pdf

I mentioned my articles because I am one of a very few people on the web with any history of studying the linearity, utility, and accuracy of internal diodes. Not only that you are the one demanding people's references (that one kinda blew up on you at the Hardforums when BillA stepped up tho eh?). The Procooling article was written to hopefully save others from making mistakes in testing; it was obviously not devoured as intended.

Consider that YOU are the only person that is claiming that the diode is a perfectly accurate measurement device. Amd and Intel just use it as a failsafe at best. The IC mfgrs all point out errors and problems in making the circuits. But your setup has no such issues. And you come to ME for proof? Typically the burden of proof is on the person making outrageous claims not the other way around.

I could write an article on uncertainty calculations and what is needed to properly separate waterblock performance. It would likely also fall on deaf ears.

Regarding Procooling's ability to put together a waterblock roundup:
Unfortunately (for you) there is no law that says I can't comment on the quality of a review without doing one myself. I am not an artist either, but if one who was took a crap on a paper plate and called it sculpture I would decline to buy it. Regardless of whether this "art authority" claimed that it was a masterpiece. A position of authority isn't everything; common sense and experience counts for something.
