Hi...I am trying to overclock my CPU. I am wondering what temperature probe to use...the one built-in, or the one from my fan master fan controller? I stuck the probe inside the heatsink, it's touching a big copper piece which is touching the CPU core (it's about 3/4 of an inch tall). The fan master says 27.6 right now, and the built-in one says 32. (My processor is actually underclocked at the moment from 1.8 to 1.4)
