I have just purchased an Asus Rampage Formula Motherboard with an E8600 not overclocked at this point and running an Blue Orb 2 fan in a Thermetake Armour Case, I have the below temperatures and a bit concerned about the MB temp as my last board the P5K premium the MB never went over 35-40 yet the below temps are idle temps
CPU 37 C (happy with that even under load does not break a sweat)
MB 55 C idle
NB 47 C idle
SB 51 C idle
If i take the side of the case off MB drops to 48 as does the south bridge so around about 7-8 c cooler with the case side off, not sure what that means.
I know the x48 chipset runs hot and not too worried about the northbridge and southbridge temps but not used to 55 on an MB sitting at idle, I have a 8800 GTX Ultra OC and that generates a lot of heat so maybe it has something to do with the location f the MB sensor being affected by the GPU heat. There is no real apparent heat in the case and I am operating from an air conditioned room, thanks to any one who can offer any advice as I would like to see the MB temp around 40 at idle
Your temperatures are fine. A little on the high side. You could add fans to the case. The computer will be noisier though.
Not sure how dependable those temperatures are. The software may be incorrect.
I have the same problem... my MB temp is around 52degrees(@idle)... My friend has the same MB and his one reads normally(around 28 degrees). He has a crappier case and I have a nice high airflow CoolerMaster Storm Scout, which is designed for gr8 airflow. I'm beginning to wonder if my sensor might be funky...
