New means hotter?

Upon upgrading my M/B from an ECS K735A (SiS735 Chipset) to an Chaintech Zenith 7NJS (nForce2 Chipset), I kept all the other harware.My CPU is an AMD1700+ and i had a cooler from Spire (all copper base and 6000 rpm cooler). My old system used to run o.k. for about 9 months at temps 42-46c.
When I installed the new M/B and moved my other stuff to it, the cpu temp went up to 62-68c, and windows XP couldn't run with stability, unless I reduced th Vcore from 1,750 to 1,675 from BIOS.
SO i was forced to by a Volcano 9. The temp now is 58-62c.
When i move back the hardware to the old M/B but with the new cooler, the temp drops to 38-43c.
Do you believe that is something wrong with the new M/B?
I use exactly the same hardware, the same box, and the same greese, apart from the M/B.
 
A couple of possible explanations:
1. The mobo is overvolting the CPU... you have to check on which real voltage it runs.
2. Your mobo doesn't read the correct temps... all motherboards have their own temp values which can't be compared.

My dual-PSU PC is so powerfull that the neighbourhood dimms when I turn it on 😱
