You are within the specs of the adapter so it's fine, and it's not that unusual that they put out heat like that when you're drawing nearly 3 amps from it. This is when you add a 3rd fan, something a little smaller, just to blow on the adapter to keep it cool.

Or replace the adapter for one that doesn't get so hot at 3 amps.

I would go a/c the only reason to do all this is if you already have the stuff around or at least most of it.

yeah i know i had 4 pc fans in my case and had a 12v 5 amp adater but that im thinking about i think i wired it wrong...the adater had 3 wires 1blk 1red and 1 yello... i twisted the yellow and blk together as one ground maybe that yelow wire is the problem
