i dont get it,

I recently changed motherboards from an ASUS A7A266 to a Gigabyte GA-7VAXP Ultra. My cpu(2400+) temps with the old mobo were 39 idle, 45 load using a thermaltake volcano 7. With the same hsf the cpu now runs at 66 idle, 76 load. I've reapplied Arctic Silver and the temps stayed high. The cpu is running at the same stock speed of 2000MHz.

different temp senors on mobos read the values differently. The only way to know for sure it to get a laser thermonitor and try to take reading from the side of your core.

Sounds about right. V7 has a very crappy hs and a terrible temp sensing fan. It's old and outdated. I dunno why Thermaltake claims it can cool up to XP2800.

My volcano 7 has served me well, but it is time to upgrade. I have been running it with a 39cfm fan at 5V and it has kept my processor at 35c idle w/ case ~28c.

Is the HS seated correctly? Not backward or anything? If not, the board probably read the temp diff.

How does it sound about right? Going from 39 idle to 66 idle sounds about right?

Aside from the heatsink not being seated quite right, the only other possibility is that the new board is reading the thermal diode on the CPU's die, but I'd expect the temp then to be in the mid 70's.

No, it sounds about right that it was always 66 idle and your old mobo was reading it too low. The V7 came out right when XPs were coming out, so I dunno why it'll support up to 2800. Have you checked the fan speed? Since the V7's fab measure system temp instead of CPU temp, it might be running slower if you improved the case cooling.

It was on backwards . Temps back to normal. I just assumed the letters on the fan would not be upside down when installing it, guess not though.
