High Temp question

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...

I don't think so. My chipset temp is 30* (not sure if that's North or South). My CPU fan is 3-pin and the MoBo is 4-pin, but my previous two boards were the same way.

It got so bad earlier that I had to take a small personal fan, take of the case siding and turn the fan on high to cool off stuff.

Larger board means more circuits over a larger surface. If you look at the second temp in SpeedFan that's usually the board's temp even with a dual or quad cpu installed. Temps between the high 20s and 40C after running for several hours are still in the normal range while not ideal. Different makes and models of boards will also see various temps due to the amount features on them and what is active.
 
Sorry for the delay with a response. p5n32, yes, I'm a pro with thermal paste and will often spend upwards of five minutes making sure it's perfectly applied (while my wife watches me and shaking her head) (I'm OCD like that) :P

PC eye, I suppose that makes sense. I've always labeled it as 'Chipset' on my SpeedFan and right now it's holding perfectly at 29*C (would go up and down a 2-3 degrees on previous Boards). Really, everything is fine temp-wise except the CPU as it now Idles higher with this Board than it did under load with the other.

I went and ordered the Intel D945GTPL from TigerDirect yesterday so it should arrive Monday or Tuesday. It's a Micro-ATX. I still have my ECS (also Micro-ATX) from my previous RMA so I think a little bit of testing is in order to compare the results. Would posting the results of identical systems using ATX/Micro-ATX be worth it to you or anyone else reading this thread or has that been done before?

Ouch! Larger board generally see a wider power distribution since they offer more features, more dimm slots, maybe 3 instead of 2 pci slots, and more sata ports depending on the make and model. With the newer full sized boards seeing these things you generally need improved air flow.

One good example was what I mentioned earlier about upgrading the old Socket A case here and seeing high board as well as cpu temps until moving everything into a better cooled case which then saw great improvements overall. As far as posting results being seen between temps on micro atx and full sized boards it would be an object lesson on how keeping board temps low will also help keeps other temps down in the long run. You won't see any objection here.
 
I couldn't comment on the looks but the pair of front and rear 120s are supllimented by seeing one or two additional fans on the side cover. That can be a big help getting air moving around video and sound cards at times. Steel not aluminum is also a plus for the low price of only $30-.

The one thing that saw a big difference when even the Zalman 9500 was still stock hsf type temps was getting some air flow going and drawing cooler room air to flush out the heated air otherwise trapped inside the old case here. Take the board you are seeing the highest temps with and try that to see the difference then.
 
I've finished collecting all my data and will have the results either later tonight or at some point tomorrow.

I'm not sure why I still don't fully understand this, but what do board temps have to do with CPU temps? Same exact CPU with same exact heatsink/fan. If anything, wouldn't the chipset temps be hire and the CPU stay at-or-near constant?

Anyway, the results may be a bit surprising when I post them!
 
Ok, this is a screenshot I just took showing the same numbers from two programs (SpeedFan and PC Wizard) but with different labels as to what those temps are:



In SpeedFan, I labeled my CPU after opening multiple programs and seeing what number jumped up the quickest. How does PC Wizard determine it?
 
PC Wizard shows 26C for the cpu temp there. With the latest SpeedFan you now see cpu, chipset, ambient, hard drive unlike all previous version where the cpu and board temps weren't identified. In PC wizard you simply look down lower at the processor temperature. For a 3rd opnion or to simply compare the reading with a 3rd tool against what is seen in the bios the SIW tool displays readings when choosing the sensors item. http://www.gtopala.com/siw_on_pc_world.html
