So I just installed my new MoBo this morning (Abit IL9 Pro) and my after getting everything up and running, my CPU temp at Idle is about 10*C higher than it was with the ECS and Abit IP-95 before it. I have the same amount of fans in the same locations, and exact same hardware layout as before. SpeedFan shows an Idle between 40* and 43*C.
My first thought was EIST, and looking in BIOS, I could not see a setting for it, but CPU-Z shows a multiplier variation between 12 and 16, so I know the CPU is cutting back when not needed.
I triple checked to make sure everything was 100% hardware-wise, and reapplied thermal paste twice now. The CPU Heatsink is installed and secured.
Am I missing something? Anyone have any ideas? Gods, if I have to RMA another MoBo, I'm gonna be peeved. Thanks for any suggestions.
Stock or 3rd party cpu cooling? Front intake fan? Side fan? Front or side vents at least? The one thing that see cpu temps brought down is actually keeping the board temps down too. With a Zalman 9500 on an older build the case itself was the big issue and was soon replaced to see board temps drop 17C and the cpu's drop 11-13C overall. It didn't matter that the Zalman had a large array of copper fins and heat tubes. It did matter that the new case then saw a 140mm front intake fan getting some cooler air in and moving air around better.

Masscool CPU heatsink/fan. 80 mm front intake (1/3 blocked by a HDD, but was like that before too), no side fan, and no vents.
Current temps right now: Chipset - 30, CPU - 42, HDD1 - 39, HDD2 - 37, GPU, 49. Ouch! Previously, my chipset was around 27-28, CPU only saw 40+ under load, both HDD's averaged around 35, and not sure what the GPU was - I think maybe 45 or so.
When you say 'board temps' what do you mean exactly? I've built several systems before, so I admit I feel a bit naive by asking this, but this is my first experience with an ATX board (all previous have been Micro-ATX) so could that make a difference? Honestly, everything is in the *exact* same spot as with the previous two boards. I was actually able to tuck some wires away in a corner thinking it would help airflow, but apparently not.

Since everything is the same other than the board. Sometimes Different boards temps. monitoring can vary a few degrees, plus after it runs a few days and the compound sets it should drop a few degrees

Hmm. Well, I have another 29 days for it to work itself out or else it gets an RMA. IIRC, my IP-95 and ECS 945GZT-M gave me right right temp from the get-go with fresh thermal paste. Can different boards really be off by 12 degrees C?
I'm very concerned about this problem since the CPU already had to self-shutdown once while it was under load, and it was set to do so at 60*C. I've since upped it to 65*C, but that makes me nervous.
At least Ubuntu works with this one. Silver lining...

No, it would be a flaw if it was off by that much. Since you changed out the processor before I suppose you did the compound right. Do you have the CPU fan control set to auto in the bios, in other word is the fan speed kicking up when the temp rise. I had a Foxconn board once that said every CPU I had in it ran at 70C at Idle and under load

I'm a pro with thermal paste
BIOS fan control is on, but the CPU fan never goes above 2700 RPM according to SpeedFan.

What a re you using for a compound there? When going to upgrade from an old Socket A board to a 939 the lack of any front intake fan and no vents see a 46-48C idle temp for the board and 44-46C for the cpu. Once in the better case the board then saw 31C with the cpu at33C.
That made a workd of difference temp wise by seeing the increase of cooler room air brought into the case. A micro atx model board actually sees lower temps since it has less surface space that needs cooling. Now that you havce a full sized board in you should calculate the additional cooling to see the temps lowered there.

Well, I just added a spare 80mm fan to the front to help bring cooler air inside. Really, it just looks like it's helping the HDD's. I really don't want to spend the money on a new case right now.
I never knew temps took MoBo form factor into account. I've had systems that ran hot, but the Board was always super cool to the touch. Is there really that much difference between ATX and Micro-ATX when it comes to this?

Could northbridge temperature heating up the case/heatsink? Try hotglueing an 80mm fan to it temporarily, and turn it to it's max. Check temps again. Also make sure you mobo has an 4pin slot if you cooler is 4 pin, and if you mobo is 3pin and you have an 4pin fan...
