Does this mean a fanless heat sink?
Chrispy_ wrote:'tis a trick of the perspective. The tips of the fans (where most of the airflow actually is) overhangs the heatsink by quite a long way, IIRC.

Made with more than double the process node of the CPU, temps at 70 C is no problem. On my 900-series motherboards, the NB heatsinks are always to hot to touch. In this system, the thermistor for the NB reports 35 C at idle, and my IR thermometer reports 60 C on the heatsink. Under prime95 load the sensor reports about 50 C and the metal is over 70 C. According to Gigabyte, the NB max temp is about 80 C on my 990FXA-UD3 rev 1.0. I've never been close to that IIRC.

just brew it! wrote:Your thermistor must be mis-calibrated then. Or it is measuring something other than NB temp.

TMPIN0 = Sytem (Motherboard) Temp
TMPIN1 = CPU Temp
TMPIN2 = Northbridge Temp
