Fan Placement

Okay so i have a Thermaltake Overseer full tower case with the Corsair H100i mounted up top. My fan on the back failed a while back and i need to make sure i get it cooled correctly. The front of my case has room for 2, 200mm fans and the back of my case has room for 1, 120mm fan. What fans would you guys recommend because it's looks like the 2 front 200mm fans would be pushing air in and 120mm exhaust out of the back.
 
Far as I can tell there's only room for one 200mm on the front.

How is the H100i set up - is it intake or exhaust?
 
i think lehtv is correct... it only takes 1 200mm in the front... 2 up top.

I don't know why i thought there were 2 up front damn, well not sure where to put the other one i bought because i can't up top because of my H100I
 
Nah ill keep it im sure it will come in handy sooner or later i have coming 2 of the Cooler Master megaflow 200 and a Noctua nf s12. I'm not sure 1 front 200mm intake will give me enough air but i know the Noctua will do fine as exhaust just hoping intake will be okay.
 
Ahh okay maybe it will be enough


I7 4790K
H100i cooler
GTX 970 on it's way
8 gig RAM
250 SSD
2TB storage hard drive
 
Technically that setup doesn't need more than one 120mm intake... The H100i can be your exhaust. GTX 970 doesn't dissipate all that much heat, and much of its heat is blown out the back anyway. In other words, 200mm front + 120mm back + h100i top is more than enough even if you run the case fans at minimum RPM.
 
no the top should be intakes..

have the radiator pull air from outside down into the case.

Also AIO's in horizontal mounting positions aren't that great... reason is because most are not properly bleed.
Horizontal laying allows a air bubble to be spread across the entire radiator which can hinder performance.

Yeah but wouldn't that pull hot air off the rad into the case?

With the H100 mounted in the top I assume you have fans on it? If so, then the top case fans are probably not needed I suggest removing all unused PCIe slot covers from the back with use 2x 200mm front intakes and the 120mm back exhaust.
Here is a link to a bunch of info on airflow and cooling. 1st is index, click on topic to see it.

It was brought to my attention i only have 1 200mm front i had thought it was 2 for some reason but turns out to not be the case. Yeah i have fans on the HI00i

Best way to bring cool air to top half of case is a 140mm fan in 3x of the 5.25" front bays.

I have very limited experience with 180mm & 200mm fans, but what I have seen is they are not as good as 140mm fans. My Enthoo Luxe came with a 180 front intake .. now has 2x 140mm intakes being much quieter with much better airflow. To date I have not seen any CLCs and only AIO that is good is Swiftech H140-X, H220-X & H240-X are good, but they are not CLC. They are basically component kits which can be expanded, individually replaced, coolant changes or topped off, etc. All CLC are AIO, but not all AIO are CLC.
