I just built a computer and am using the Corsair Carbide 200R for the case. I bought two extra fans with it and was wanting to know what you guys thought about where I should put them. Currently I have 1 outflow in the back and 1 intake in the front of the case. Now both fans that I have installed are 120mm and the two new ones I have are also 120mm. I have two spots on top of the case. Two on the side directly on top of the MB. Also one on the bottom next to my PSU. Any help would be appreciated. Thanks.
Remember in my opinion its always better to have positive case pressure to stop dust and dirt ingress into the system and this will also ensure alot of fresh cool air in the system which will push the hot air out of the top empty slots.
