I suggest checking the temperature in bios rather than using a third party prog. The motherboard temp could not be that high while the CPU is only at 35 degC. I suspect the program is incorrectly reporting your CPU temp as Motherboard.

That said it is still very high and you may need to look at cleaning more than just the fans. The CPU heatsink could be clogged up with accumulated crud. You may have a poor contact between CPU and heatsink. Remove the heatsink. Clean off old dried up thermal pad/compound. Renew thermal compound and reinstall the heatsink after cleaning out the cooling fins.

You realize the mainboard temp is basically the the same thing as the internal case temp, right? How would cleaning or replacing the heatsink & cooling fan affect that? I can all but guarantee you that your board is NOT at 79C. If it was, how could your CPU & HDD be in the 30's? 79C = 175F. If your system was truly that hot, it would be like an oven. The sides of the case would be very warm to the touch & when you removed the side panel, you'd get hit in the face with a blast of hot air. All you have is a temp reporting problem. You're trying to fix a hardware problem that doesn't exist. Try updating your BIOS.
