Giga P965-S3 mobo runs hot???

I was in the bios changing some setting for ram testing and I looked in on the temps and was surprised to see my system temp at 48 degrees with an open case. I've been worrying about cpu temps for a while with my e4400 and never noticed the mobo getting so hot. I put a 120mm fan blowing into the vidcard/SB area and temps dropped 10 degrees. Ambient temp is 27 degrees so the high system temp worries me. I have a small fan I put on the NB but the SB is very hot to the touch and the 120 fan is blowing on it. Is this a normal thing for system/mobo temps? Can't ever recall a system temp being higher than the cpu temp before, especially with an open case.
 
So... is the 48C before or after you put the fan in and the temp dropped 10 degrees? Speedfan reports my system temp at 46-50 but I'm not worried. You're correct though, my CPU temp is higher at 51-54 and so is my GPU at 68-70. 🙂 All idle temps with the case closed.
 
It was 48 before the fan. I turned on the AC in my room and the temps have dropped but the system temp is still 9 degrees hotter than the cpu.
 
I would guess the system temp sensor is in a bad location so it picks up heat from a nearby component. Every mobo I have had reports high system temp but one. My old Abit had a plug in thermo sensor you could place so it could report accurate case temp. To bad no one does this any more as far as I know.
 
By looking at the north and sounthbridge heatsinks on the board in your link compared to several other 965 boards, the ones in link look small. If you are worried about the chipset temps add a fan to the southbridge heatsink and replace the northbridge heatsink with a larger one.

I would never raise any voltage until needed to to return stability. What bus speed are you running? A friend of mine has the same board as you running 446 fsb using a E6300 and all voltages are stock except ram voltage. Voltages needed can vary board to board for a given overclock so your millage may vary.
 
Running a 300 FSB. Got a small fan on the NB and the SB heatsink is small. BTW, how is that MSI mobo? Been looking at that one for a while as a possible replacement.
 
My temps are the same way....don't sweat it. The north bridge runs at 70C if I'm priming for an hour or two......hotter than the actual CPU.

Both the northbridge and southbridge coolers on these boards are rather weak.

Boy I doubt you would need to raise any voltage. Ram voltage if you ram requires it.

I did not see your question about my P35 Neo2-FR. First you need to know I'm the most picky person you will ever find. With that out of the way. System stability is excellent. Overclocking is very easy. The heat pipe cooling rocks. The board layout is about as good as it gets and looks nice in my opinion. Some people do not like the color choices used for the memory slots etc. but I do not mind.

The quirks that bother me are. Only 2 of the 5 supplied 3 pin fan headers allow speed control and RPM reporting. The hardware monitoring chip or its programing cause my 80 mm case fans to run at less than full speed when connected to the 3 pin headers that allow speed control. I'd guess about 20% slower than full speed. The case fans seem to speed up as system load increases. I use 2 high CFM 80 mm case fans so the fan speed change is easy to hear. I checked all voltages being delivered by my PSU and the voltages are rock solid so its not a PSU problem. This is with all bios fan controls disabled. I have not found anyone complaining of this but me. Most will never complain because they use low RPM case fans that are quiet. So the change would not be audible. I called MSI and was told they would look into this but they never got back to me.

The only other thing that bugs me is the double boot or double post at bus speeds over 370 mhz. This is common on many newer motherboards and is claimed as a feature that checks stability on boot up and if ok reboots and continues with the boot process. I'm using a old Audigy sound card that has always thumped my speakers if turned on, on cold boots and the double post on a reboot causes my Audigy to thump my speakers every time I reboot. So I have to turn my speakers off to reboot which sucks. A different sound card would eliminate the thump so its my fault I did not replace my sound card years ago.

Keep in mind I have only tested this board with the hardware in my sig. No raid, no SATA optical drives etc. I did try the onboard sound just as a test and it worked and sounded great. I just wanted a hardware based solution so I used my old Audigy.
So mileage my vary depending on hardware used.

In the end if I needed to buy another board I'd buy the P35 Neo2-FR again no problem.
 
Thanks wonderwrench. That mobo is supposed to be based off the platinum one and reviews have been good. The mobo getting so hot has really surprised me and I think the heatpipe cooling is the way to go.
