OK, my system is too hot.(150f, this registered on every motherboard monitor i got, and in bios!) I have a global win h/f on my pc, and 2 add. fans in the case. Should I buy a better motherboard heat sink, with a fan on it? And also, do you think my voodoo 3 needs to be cooled anymore? Someone suggested that those 3 things need to be ffixed with better coolers. I'm not overclocking, I'm just playing games on my k7 900mhz. thanks!
