Hi all,
I would like some advice. I run a Intel core daul 8500 I have no problems with over heating errors but I did notice something that may be a concern.
In the bios it shows the CPU temp as running between 33C and 40C. But when i run SIW or Speed fan results it shows two CPU temps:


As you can see the temputures on the top are normal but below that they are running at 70C Is this a concern or nothing to worry about?
I have updated the bios, all fans a running ok, no dust ect. Well ventilated area.

If you don't notice any problems, I wouldn't worry too much about it. My processor (a Core 2 Duo E4400) use to get up around 70C while under loads, and once I overclocked it too far, I got it up to 80C! This caused the system to have frequent lock ups, and eventually BSOD's.

Also, you can't be sure of how accurate the program and the cpu/motherboard sensors are.

If you do want to reduce temperatures, it is a good idea to get some arctic silver 5 thermal compound. If you're using the thermal paste that came with the cpu, it's usually not very good.

Hi Sterling, thanks for the advice. The other PC also runs Intel, 5500 daul core but only sits at 34C so I was a bit concerned. I agree if no problems don't worry to much. My system is stock no over clocking.

Hi, can someone tell me why the CPU temps read two different readings? As I stated the bios shows the first line, why is the second line reading 70C?

I think the top temperature, the cooler one, is for the whole processor. This may be more of the outside of the processor too. The core's of course, are the two cores inside the processor, which are going to run hotter than the whole processor.
