Max temp for 8400 GS

Solution
You should then remove the heatsink, clean it, remove dust from the fan and heatsink, reapply new thermal paste, and put it back together. That, and improve if possible the air flow in your case. But it's a very old card (very old! 2008!), even overclocked it won't deliver much. Any modern card (the low end, $40, GT 710, for example) is way better than that.

I have the same card and i've overclocked it to 670 (667) CORE and 770 (769) MEMORY, almost max (going past makes my pc crash) and the hottest i've seen is 62 C on Afterburner.

I don't know if this is normal though, i've asked and some guy just answered "no"
