Posted October 1, 2014 I have ordered the parts for a new build, but I am beginning to wonder if case pressure will be an issue. I have a 450d, which comes with two 140mm intake and one 120mm exhaust. But I am putting in the h110 (dual 140mm), and was intending for that to be also exhaust. Is this going to be an issue?

Posted October 1, 2014 LOL this is my config WITH THE SAME rad/case combo I have Front 2 140mm - intake I have bottom 120 - intake Rad fans - exhaust Rear 120 Exhaust but make sure the Pump is attached to another fan header besides CPU_FAN (it messes up sometimes with the H110) and put the rear 120 exhaust on CPU_FAN with a low speed adapter if you can. This is what I do. Are you new? Please read CoC Before posting!

Posted October 1, 2014 Nope. Difference between positive and negative pressure inside the case is that positive pressured case doesn't accumulate dust quickly compared to negative ones.

Posted October 1, 2014 So an intake at the bottom might be a good idea? (also you have good taste) I bought 2 AF120's one for rear and one for bottom. But for the bottom, WARNING, the actual fan holes for it wont work at all if you have a Power supply like the RM650. I had to screw it in using the fan grill holes already there. No issues though, and it also isolates the fan from the case a bit better. Are you new? Please read CoC Before posting!

Posted October 4, 2014 @CaffienatedBovine one thing to consider. filters tend to "limit" airflow. 2x 140 filtered intake is really 1x 140, 2x 140 is really 2x 140 exhaust. so you are already working in a "negative" scenario. adding another 120mm will reduce the negative, but minutely. honestly, the dual front and dual top as intake (roof is filtered) will improve the pressure issue, without compromise of massive dust collection. case is naturally ventilated enough not to impede any exhaust over-run.

I feel like I should be more worried about bringing all that heat directly over my components through the rad. Is case pressure really going to be a big issue? The way it's set up right now, dual 140 kinda filtered in (not very fine mesh), dual 140 filtered exhaust, and 120 exhaust at the back. Link to comment Share on other sites More sharing options...

The way it's set up right now, dual 140 kinda filtered in (not very fine mesh), dual 140 filtered exhaust, and 120 exhaust at the back. not really other than dust control. the air through the rad through the mesh and then through the filter is very restrictive on the exhaust side of the cooling. you have the case, you can find out a lot just by repositioning the fans and locations. from what i had found using the 450D was the front inlet was far superior to the 350/750D but the filtering was deemed "low restriction" but still was taking a lot from the flow rate and capacity to move air into the case. the amount of air penetrating the interior was but a whisper and was relatively a non-cooling component with the OE 140L fans. as to heat from the radiator making an issue with interior components, again a non-issue if the front fans were more of a player.
