Joe's comment on TCs vs. thermisters is correct - but does not go far enough
(I not referring to the Asus board reference, thats a different (bad) deal by itself)

do a spot of work with the manufacturers of these devices:
you want to know the devices' and instruments' "stated accuracy"
(for a type T TC it is +/- 0.5°C or 0.4%, whichever is greater, thermisters run arount 1.5^C, and much greater - to 3^C)
THEN, to this you must add the effect of the meter's "stated accuracy" (these are calculations, not sums)
and the numbers will render damned near moot your measurements

I just had a BIG conversation with Omega's engn dept about 1 tenth degree variations, and they laughed at me

so do appreciate that the VERY BEST POSSIBLE temps you might read are +/- 1^C

valid readings of greater accuracy are possible, but ever more difficult
+/- 0.1^C will cost ~ $500 (with USED equip, RTDs only)
+/- 0.01^C will cost ~ $1500 (with USED equip, $2500 is more probable)
[I am now using sub-minature custom made - and calibrated - 4-wire RTDs,
and a calibrated meter with 0.001^C resolution; to get 0.01^C accuracy]

so EVERY TIME you see "34.6^C" think Bull Shit
the real number might be between 32 and 37
