Hello again everybody I've been posting a lot lately I have tons of questions that google can't seem to answer. Anyways my water cooling parts are getting here tomorrow finally!! (RX360+tubing and fittings) Now here's the thing Based on my case (cosmos S) which would be better and why?? I'll mount the RX360 up on top and use a Push/Pull fan configuration. I tried to do a 3d model of it but I'm not really good at that at the moment so i settled down with paint biggrin.gif here's how it would be like. BTW currently I'm using 3 fans as intake in the front 1 in the bottom and the back and top 3 are exhaust.

I'd say intake...warm air goes where you push it (credit goes to ehume)...it's been working for me with my M2 and CM690II...

1 front intake (140mm), 1 top intake (140mm), 1 bottom intake (120mm) , 1 rear exhaust (120mm) and 1 side exhaust (140mm)...

With this config I was able to drop my CPU from 35*C to 33*C idle and from 41*C to 37*C on load.

I used to have the top exhaust but now it's running a lot cooler by a few degrees. But that's just my setup and my experience.

The second one for sure. You want the coldest possibe air goin through your radiator. The exaust in a water cooled system isnt as important as it is in air cooled systems. So having just one exaust fan would be fine. Also having more intake fans would create positive case pressure which is also a good thing to a point.

I guess It will be as intake then So i should keep the 3 fans in the front pushing fresh air as well? let's say blowing that and the exhaust from the rad towards the back of the computer right?

Intake is the way to go.

Yeah, keep you front intake as is. The rear exhaust will do its job just fine.

Meh, Alot of it is going to based on personal experience... like everything else.

When you get your system set up, if you want to experiment, try both methods and adopt what works for you.

Alot of us have done this and gone with what gives us the best temps.

In theory, intake should work better because its drawing in cooler air through the rad. Having said that, ambient room temps will play a big part of your results.

Intake, as long as you put dust filters on there.

Last thing you need is a cloud of dust in your case because you're missing filters.

Also, a nice advantage of an intake general system [positive pressure] is less dust. Since all your cool air is going through the filters and you essentially have more air in the case than gets exhausted, air seeps / rushes out of any available slit, hole, vent possible, which prevents dust from sliding in there. In a mostly exhaust orientation [negative pressure] air rushes in, and with it dust. smile.gif

And I'll admit, ever since I got my FT01, I became a fanboy of positive pressure. It's a wonderful thing wheee.gif

Yeah I guess I'll have to play around with the fan setup for a bit, intake really makes sense now that i think about it (pictures an intercooler getting fresh air from the front) BTW my room temps are usually around 21C (no AC) I think that's good right?
