Assuming that you are using supported hardware:
To be honest, the temperatures that you said in the notes dont seem to be quite a lot for the CPU. Because 65 degrees seem okay for pentium/d family, and the 135f = 57.3 degrees celcius which is still okay.
The best thing to do is to check on the website below:
Get the SL number of the CPU and check the thermal specs from:-
Make sure to have the latest bios for the board.
Install the Software Intel Desktop Utilities to see if it points any voltage errors.
Now regarding the burnt smell, this can be something bad, it can be an issue with the board and power supply, so it is best to identify it asap and get it replaced before something wrong happen with the CPU as well.
High temperatures can due to:
a) bad integration
b) PSU not ATXv2.2
c) Chassis is not TAC (Thermally Advantage Chassis)
d) BIOS Issues.
Steps to try:
Re-integrate the cpu with new clean thermal paste.
Update the BIOS of the board.
If not, fixed, try the system out of the chassis as a test.
Make sure that you have a good PSU as well.
All the best,
Thanks for the reply, and the information about those temperatures. I was afraid to act, not knowing if the temperatures were excessive, and needed the encouragement.
After a careful inspection, I popped in a 630W power supply, it seems to have solved the problem. No more smells. Thankfully, everything is working, and there is no apparent damage.
The motherboard is now cooler, current temps are:
Zone 1: 100F
Zone 2: 88F
The burned smell was from a melted plastic connector and one of the current limiting resistors in the Ultra power supply. It may have been over amped, but it was probably just a defective all along. I didn't catch it because the voltages were all stable, and still are under test.
I also noticed that the UPS kept beeping when devices that were not attached to it, but were on the same breaker, were turned on, now it is not. I don't know if that means anything, just thought it was worth mentioning.
