now this is only after 3.5 months of use in a push pull setup. (my grandpappy's holding the rad, and I'm snapping the pic). so me grandpappy is saying well WTF - those top fans are probably creating weird air currents seeing as how that dust is in a layer on top of the rad...maybe try to get rid of the top 2 fans? see how it goes. good thing too cuz I broke 1 fan's blade. expensive $^&#er. but I digress.
I disconected (did not yet remove) the top 2 fans, with only the bottom 2 pulling air thru the rad. as far as the temps go I haven't really noticed a difference to be honest. I don't right know if that's a good thing or not.
the advice I am seeking is - should I remove the 2 top fans so I'm left with a PULL setup or get a replacement fan for the one I broke and go back to the old ways?
