Watercooling...dilemma

post #1 of 7
Thread Starter 
I've modded my 500r to have a 280 radiator in the top, a 140 rad in the back along with a 240mm rad in the floor.

The 280 and 140 are currently being used a exhaust, but seem to be pulling enough air to create some negative pressure and dust. I thought about turning one around, but I feel like the exhaust from that one will feed into the other and cause higher temps. Flipping both seems a little foolish because of the lack of exhaust. Any suggestions? Anyone else with a similar radiator setup? How is yours setup?

In general, cases are not very air tight. So having two of your rads as intake and one as outlet is a pretty good arrangement. That is how I have always done mine anyways...

What about one of the rads intaking the exhaust from the other?

There is not a great deal of heat exchange in a single pass of air over the rads. You will see a lot of people "stacking" radiators to get more cooling capacity and it works fine.

Do what keeps temps lowest in the box and keeps the dust out. Any other considerations, such as the one you mentioned, while worth looking at, aren't going to make a considerable difference in overall temps.

You could always get the magnetic dust covers for the bottom and back rad and make those the intakes with the top rad the exhaust
