Woh... seems very low for an overclocked CPU, and would even be low for a unclocked CPU!!! Those temps can't be right...
You must be using some kind of water cooling like ZoomTm said, but I'd expect your mate to notice that and tell you then that it is normal.
It is possible though for the bios to be giving you a fake readout. All windows programs will read from this too.
