Hi all, i am having AMD 9850 black edition... but the CPU temp goes upto 65C

while playing games like NFS undercover, Left 4 dead etc other higher graphics games....
I have 8800GT graphics card and ASUS M3N## motherboard...
I think this much CPU temp is too high... and because of that only some of my games gets closed suddenly

....
Please recommend me something on system temp with my current configuration...
How can i bring down my system temperature..
