From: tedgeizen on 7 May 2008 08:07 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.

You have no guarantee what Speedfan is reading. Check all other fans for proper operation and that they're free of excessive dust buildup. Check the bios hardware health/monitor page to see if it has temp reports there. Temps may slowly increase from thermal compound degradation but this seems more sudden, since the monitor goes out I would tend to suspect the video card first, although bad power or bad motherboard might cause it. You might examine motherboard for failed capacitors and use a multimeter to check PSU voltages (and/or check bios hardware reporting page), swapping in another PSU if no other fault can be found and the same goes for video card. If you can determine the CPU is overheating, take the heatsink off, examine the interface, clean it off and apply fresh thin layer of thermal compound. If it uses the original thermal interface material you may need rubbing alcohol or a petroleum solvent to cut through the material, dissolve it to more easily wipe it off. The temp could be a false reading. Since you hadn't ran speedfan previously to have a baseline figure for these temps, they might not be an accurate indication of anything and you may have another cause of the problem - whether it be something overheating or not.
From: tedgeizen on 7 May 2008 11:53 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!
