Help with case fan

[Sokratz]

I have a watercooling setup and I need help placing a case fan. I'm not sure if it should be blowing In, right on the radiator or out sucking air out over the radiator. Just about all the components are actively cooled.

Here is my current setup (note, i do have a SB fan as well that I forgot to put on it), I know it's messy but my temps really arnt' that bad. It's hard to see from the picture but the radiator is actually on top of a spacer, so air does get under there pretty well. My problem is that with the case on, and my room at 90F the temps get up there. AirFlow

(1) Should I put a fan Here blowing In, our Out?

(2) or should I put it Here blow out?

If it helps at all, here are some more various thumbnailed

Thanks much!

First, I'd sleeve all those wires ... pretty bad for airflow

I don't have watercooling yet but I thought if you could duct out the heat from the radiator you may not need any more fans, maybe mount the rad on the side with a fan blowing out if there is room. Or any place it will fit. I have seen some with the rad in the back with the fan blowing/pulling out.

blow air in on to the radiator.. think of it this way if you burn your finger do you blow on it to cool it or do you try and suck the heat off of it.. ..

Ditto. You've got plenty of fans for the basic air cooling already, but that radiator probably isn't doing the greatest the way it is (but also, it doesn't look like there's much room for it elsewhere)
