I have a "mainboard" temp not NB specific. My mobo is MATX and from the research I've done no-one has specifically located the sensor,,,, I can tell you with a fair degree of confidence it ain't the NB. PC probe reads 19 idle and 25 load on the cpu and 35and 40 C on the MB. I use PC wizard for temps other than CPU, because PC probe is such a joke for temps. My quad idles around 30 and loads at 40 I've been tempted to go over the mobo with a fine jet of compressed air ti find the area it reads, but I'm too lazy.😀 Actually I've got too much on my plate at the moment, one of these days.:roll:
