I would like to add some fans to the Artic Liquid Freezer II 420 for a push pull configuration. However I do not know what type of screws I need. I keep calling Artic customer support but I don't get through. I know they are obviously long screws since the regular small screws that you typically use won't reach. Can someone help me out here?
Take an existing screw, to a hardware store, to find the right thread size, and length. At least that is what I have done in the past. Take a fan with you, also, so you can be sure to get one long enough.
