I purchased a VIA EPIA M10000 Mobo 2nd hand from these forums, now if didn't come with a fan on the CPU Heatsink. I am using it for a carputer, but i have a problem where i get colour streaks across the screen. I am pretty sure it is because of heat, as it doesn't occur straight away and its only after the computer has warmed up... I have been using a 40mm fan i purchased off ebay but i don't think it must be good enough. The CPU has been running at about 50c on my bench. I am unsure what temp it runs at in my car... (it is under my seat) So I am wondering where i can source a suitable 40mm fan that will keep my CPU cool and happy.
