At idle the difference in my temps is about 2c under load its about 6c (ish). Your reading may be inaccurate. If so then assuming that things run fine now, regardless of the improper temps reported, so long as those improper temps remain "improperly" the same you shouldn't be too concerned.
However this is OVERCLOCKERS.COM so I suggest you round your cables, put a seperat sink and fan on EVERY chip, "swiss cheese"ify you case, load up on fans and pelts and run the thing inside a walk in refrigerator in the arctic circle. (it can't hurt)
I have no idea. The program is Asus Probe and the board is an AsusA7M266/1.2Ghz.
I'm using a GlobalWinWBK92(55.1cfm)AS2 and there's a chipset fan running as well.
My case temp is <1C from ambient.
Anyone know where it may be taking the mb temp?
