ASUS A7N8X at 70C!! Please advise

Hello, this is an old system, asus a7n8x motherboard. I had been having some crashing and random problems with this setup, so i ran memtest and found the ram was bad. replaced it with a gig of kingston pc3200, seemed to be ok. checked the motherboard temp, around 70C!! seems very high to me! when hot like this, playing movies with winamp have glitches / lags sometimes.

what is an accurate monitor for motherboard and cpu temps? perhaps i need to do a new layer of thermal paste on the chip? thanks

My pc crashed a couple of years ago when being stressed in-game.
I wasn't sure what the problem was so I took everything apart, cleaned up the CPU and added some new thermal paste. Everything was fine since then and the CPU has ran about 8-10 degress cooler at idle. I expect reseating your CPU and paste could do the same thing as you yourself have suggested. Doesn't do any harm to clean up inside the case some more and try to make wiring even better for airflow. Good Luck.
