SpeedFan 4.31

post #1 of 27
Thread Starter 
I use SpeedFan to monitor my system temperatures while under load from two Prime95 torture tests. I recently downloaded TAT, only to see that the temperatures listed by both were 14 degrees C off, with TAT being higher. Does SpeedFan not like my motherboard and processor?

SpeedFan reads from a different location and is not an accurate reading of CPU temperature. TAT and CoreTemp are correct CPU temp readers.

Correct. Specifically, Speedfan reads it from the mobo sensor. TAT and CoreTemp reads the temp directly off the CPU. In other words, TAT and CoreTemp are more accurate.

Yes, as Speedfan reads it's temperatures from heat sensors and monitors on the socket, whilst CoreTemp and TAT read the temperatures directly from the CPU die, which is the main source of heat and the part which will get damaged by extreme heat. The socket won't, however, have this problem as the reading will always be way lower.

IcedEarth got it, it's a Core 2 Duo feature at the moment.

That can happen. It depends not only on what motherboard you have but what sensor ship that motherboard has on it as to how accurate your Speedfan reading would be.

I would recommend that only TAT be used for monitoring any C2D simply as it is a great tool. I did testing to find that on my system PC Probe reads only 1 degree off TAT, so I can that as it looks nicer and takes up less space on my screen.....
