Intel i5 650 CPU sensor understanding help

post #1 of 4
Thread Starter 
Hello everyone,
Well, I got this new mobo and its pretty sick . I also have AIDA 64 Extreme Edition (which is from the same folks that made EVEREST Ultimate Edition) to view all my specs and everything but Im kinda at a lost. This is the Temperature readings at idle:

Motherboard 59 °C(138 °F) [is that too hot I have a lot of fans in it]
CPU 7 °C (45 °F)
CPU #1 / Core #1 20 °C (68 °F)
CPU #1 / Core #2 19 °C (66 °F)
GMCH 51 °C (124 °F)
GPU Diode39 °C (102 °F)
Aux25 °C (77 °F)
GPU Diode38 °C (100 °F)
Hitachi HDS721010CLA33229 °C (84 °F)
Seagate ST31000528AS27 °C (81 °F)

My understanding is that the i5 650 is a dual core with 4 threads. But under my sensors info, why does the CPU 7 °C (45 °F) show up? Im not sure why it is there? Can you explain it to me?

-Thanks

There is two temps provided when it comes to the processor. The first one is the CPU temp wich is really the boards socket temp, it tells you the external heat given by the cpu and is always lower than the core temp. The second temp is the core temp which is taken directly from the cpu core. You will have one core temp for every cpu core on your processor that means one core temp for single core cpus, two core temps for dual core cpus and so on.

In most cases the core temp is the most important one for users. However the cpu temp is usefull for watercooling or L2N cooling as it shows how far the cpu is away from ambient

Thanks

Also, how cold is your i7 at idle? And +1 for you

My i7 idle temps depend alot on the ambient, on a 20*C day though the cpu temp sits roughly on 22*C and the cores sit between 27*C to 33*C idle. But with water cooling the loaded temps are were it shows, at 4.5ghz with HT on i load out at roughly 66-70*C across all cores, not bad for a processor running 1.7ghz above stock.
