Need help determining case fan size.

[ajsilva1973]

Hello all. I have an EMachines ET1831-05. I know it's junk compared to what 99% of the people on here have, but it's what I've got. It did not come stock with a case fan, so I would like to add one. I have searched everywhere on the internet for the size and wiring type I would need to select, but haven't found anything. Any help would be greatly appreciated.

You can add case fans at the back. Just get a ruler to measure what size you need.

Do I measure the screw holes diagonally? Also, how do I determine if I need a 2-wire or 3-wire fan?

Up and down, but why do you need a fan? It should be designed to operate fine without one if it doesn't come with one already. As long as your temps are low enough you should be okay without it.

Because I plan on upgrading the processor.

80 mm fan will work, you just plug it in to system fan plug.

I just want to say thanks to all of you for the help. The end result was that my case is compatible with either 80mm or 92mm. I ended up getting the "Antec TriCool 92mm Case Fan" off eBay for $6.29 and it's working great.
