    Very Hot Northbridge

    I recently (yesterday) built myself a new PC, and everything seems to be working very smoothly, so I wanted to see how it would perform under load.

    The system has an ASUS P5B-e motherboard (not a deluxe, alas), an Intel E6600 with an Arctic Freezer 7 on and the case has two 120mm fans which seem to blow the air through it pretty well. To check the various system temps, I installed a monitoring program (SpeedFan), which gives me a cpu temp of about 48-50C when idling, and about 60C (with a MB temp going from 35-40) when I get both cores working flat out on Prime95. Which I think is just fine.

    But there's a third (well, 4th counting the HDD) temperature sensor shown in the readouts, which is called AUX and is reporting a temp of (at time of writing) 127C. Which seems worryingly high, so I set out to investigate. Touching my finger inside the case, I found that the Northbridge seemed to be VERY hot, so I'm wondering if it might be that.

    I've also tried googling, and a few forums have said that the sensor isn't used, and in support of this, the system seems to be stable, with no crashes or glitches that you might expect from a northbridge that is massively overheating.

    So I'm vexed.

    Any advice or clarification you can offer?

    My 975 Northbridge certainly runs hot. The 127C reading is clearly rubbish, any chip would fry quickly at that heat. If it doesn't crash, don't worry about it.

    Yeah a thread here recently, people were saying they have stupid readings from speedfan, like -4 cpu temps and stuff, so I wouldn't take it as gospel.

    I'd mostly figured 127C was impossibly hot, but sometimes it just helps to have someone else say it too. I was more concerned about the physical (touch my finger to it) Northbridge temp, but if they tend to run hot and since it's stable, I guess I wont worry.

    Thanks for the answers
