I just got a new mobo and is the chipset supposed to be this hot? The sensor says my mobo is 40C-50C but I can barely touch both the north and south bridges for more then 5 secs. They're sooooo hot. Is this normal? Here's a pic of my mobo- http://img.xcomputer.cz/ImgW.asp?cd=AC306e&fd=f3. The north bridge is cooled with that silver heatsink and the southbridge doesn't have anything. Would http://www.ncix.com/products/index.php?sku=18623&vpn=ZM-NBF47&manufacture=ZALMAN TECH work for both of them?
