I use the sensors on my Asus A7V motherboard to monitor the temperature, and speed of the heatsink fan.

Under normal load my CPU temperature is about 42° with the case being around 28°. The CPU is cooled by a ThermalTake Volcano 6Cu+, using a 60mm to 80mm fan adapter with a 80mm Papst fan.

I use the followering CFLAGS/CXXFLAGS:

NOTE! Adapt the settings to your system/CPU!

CFLAGS="-march=athlon-tbird -O3 -pipe -fomit-frame-pointer -ffast-math 
-fforce-addr -maccumulate-outgoing-args -ftracer"
CXXFLAGS="${CFLAGS}"

I use the sensors on the Asus CUSL2 motherboard to monitor the temperature, and speed of the heatsink fan.

Under normal load my CPU temperature is about 30° with the case being around 30°. Under heavy and longtime load, the CPU temperature raises to 42°. The CPU is cooled by a Zalman CNPS 6000CU, with a 92mm Zalman fan

Under normal load (And using Cool'N'Quiet) my CPU temperature is about 25° @ 1GHz (it can reach 46° @ 2.2GHz under longtime heavy load) with the case being around 32°. The CPU is cooled by a ThermalTake Big Typhoon with a 120mm Thermaltake fan. The fan's speed is controlled by the BIOS of the Abit AN8 SLI motherboard

CHOST="x86_64-pc-linux-gnu"

This produces 64bit code.
