Need advice on overheating

[tedgeizen]

Hi,

I have an Antec SP-500 power supply that supposedly only turns on the
secondary fan when neccessary. Yesterday my monitor went black, I felt
the case and it felt quite hot. I rebooted and installed SpedFan to
check.

I got the following

HD0 29C
HD1 28C
Temp3 70C (this fluctatues between 68 and 70) !!!
Temp2 28C
Temp1 35C

Fan Speed
Fan1 0 RPM
Fan2 2813 RPM
Fan3 0 RPM

I am wondering why, if Temp 3 (not even sure where that is) is so
high, why have none of the other fans kicked in? I had the computer
off all night and just turned it on in a 19C room. By the time it
booted up and I could run speeed fan, temp3 was back to 69C even
though the case felt cold.

I tried opening the case and running a desk fan on high as a test but
Temp 3 never went below 68 (all the others dropped quite a bit though)

Could this be a false reading?
I am concerned that something is going to fry.
Thanks for your thoughts in advance.

Thanks so much for that very thorough reply. Some of that may be
beyond my capabilities but I will go through as much of that as I am
comfortable with to see what I can do.
Very much appreciated Kony!

You have no guarantee what Speedfan is reading.

Agreed. My out-of-the-box Speedfan beta 4.34 simply had Temp1, Temp2,
Temp3, Temp4.

Comparing the temp value in "PC Health" in the Phoenix BIOS and the Everest
"computer>sensor" readings and the SF reading, I determined that Temp2 was
the CPU. (They matched within a coupla degrees).

Then with F2 on the "configure>temperatures" I changed the name of Temp2 to
"CPU core".

(The beta is now the 'production' version on the Almico site)
