Hi!
I've got a Core2Duo 2.4Ghz since a year back or so. I've always struggled with temperature "problems". It's average temperature has been above 50degrees Celsius (idle temperature, even more during workload). My pal has a similar setup with the same CPU and his temperature is about 30 degrees Celsius.

So, I've got a Asus P5b motherboard and tried:
* 2 different chassis (current one with 2 chassi-fans)
* 3 different CPU-fans (Incl one Zalman-expensive one)
* Different BIOS settings (silent/normal/performance) mode but with the same result.

So what could be wrong here? Can the CPU be faulty? First I've thought that I've done something wrong with the cooling-paste but after so many tries, I seriously doubt that anymore.

What are measuring the temperature with? I remember when they first came out people were getting temps all over because of the different formulas.

It may be a faulty sensor, what are both your cores and Tcase temps at idle and load?

I'm measuring with ASUS AI SUITE:
Cpu temperature now (idle): 57degrees C
System: 38degrees C
CPU fan: 948rpm
Chassis 1: 733 rpm
Chassis 2: 792 rpm

Intels TAT's displays: 50-52 degrees C per Core.

Asus AI suite or the sensor is clearly wrong then, since your cores are 7º lower than Tcase!!

Try Everest or speedfan or something.

30 Celsius for a C2D sounds impossible with air cooling.

50C is already quite low, mine runs at 80C load (though its a laptop).

Well I think 30ºc is just about possible in a cold room for Tcase. TAT (despite being from Intel) is actually a little high, so I'd say your cores are actually 48-50ºc, which is a bit high, but very easily within safe operating limits. On the stock fan I had 55+ load, approaching 70 load and had no issues. However with a good fan you should get lower, I replace mine with a Zalman CNPS9700.

This is my current temp, with TV on (10-12%) CPU, heating on, case fans off or low and CPU fan low:

With my aerogate 3 reporting case air at 27.8ºc

In summary, 50ºc is higher than it could be, but in no way dangerous.

My Q6600 runs at 50°C with "average" CPU load. Using the simple boxed cooler. Original clock speed.
While the "CPU Temperature" is at ~50°C, the single cores are at ~70°C ...
