Case Airflow question

Hello guys,

I have the following fans and I want to setup my case for the best airflow possible:

Corsair Carbide 400R Case

2 Corsair white LED fans (comes with the case itself 44.2 CFM)
1 Corsair Stock black fan (comes with the case itself 44.2 CFM)
4 Cooler Master 90 CFM Blue LED fans
1 Scythe Kaze Slipstream 110 CFM fan
3 Cooler master stock fans (ordinary one's 44CFM)

and a Hyper 212 plus cooler for the CPU with a single Blademaster fan. My room temps are 25 to 27 degrees. My CPU is overclocked to 4 Ghz at 1.425 volts and the idle temps vary from 37 to 40 degrees and at load do not go over 55 degrees.


Please tell me which of the above fans to place on which positions inside my case for the best airflow (intake and exhaust). The link for the case is:

You have enough fans there to cover every slot in your case... 2 90cfm in the front as intake. 2 44.2 CFM on the side panel as intake. 2 90 CFM on the top and one 110CFM on the rear as exhaust. This would give you 268.4 CFM Intake and 290 CFM Exhaust for a slight negative pressure (which is what i do and what many people here reccomend as well)

Also, you could take one of those spare fans and rig it up to do a push pull on your hyper 212 +. This might only give you 2-3c difference, but if you've got the fan laying around, i don't see why not.

ok Ill do what you told me to but I have got two more questions:

1. How about bottom fan (should I install it or leave it empty because I think it will just block the airflow coming from the two fans in front of the case)

2. You told me to do a push/pull. Well which other fan should I choose to do a push/pull on the Hyper 212 plus.

Can Some one answer these questions for me please. I am waiting for answers as I have to open up my case and start replacing the fans.

The bottom fan should blow in.

thank you but I had these questions:

2. kelthic in this thread (above) told me to do a push/pull. Well which other fan should I choose to do a push/pull on the Hyper 212 plus.

If the aim is to make the insides of the case as cool as possible then install the bottom fan, however I would be a bit concerned about the noise all of these fans will make.

Bottom fan in.

The front fans will be "used up" by cooling the hard drives.

For push/pull, match the fans, equal CFMs, and a large as will fit. One into the fins, one out of the fins. One on each side, ultimatley bowing towards the back of the case.

I only have 2 hard drives setup. so is that ok for the bottom fan and which fan to use as the bottom fan (2 fans 90 CFM for the front). is a 44.2 CFM any good for the bottom fan slot?

This is how I will be setting up:

front - 2 intakes (90 CFM each)
side panel (2 intakes 44.2 CFM each)
rear - 1 exhaust (110 CFM)
up - two fans (90 CFM each)
bottom - will a 44.2 CFM work or should I leave it empty.

sorry - had to sleep. :( 

Bottom fan as an intake - use the 40 CFM. Push pull with the last 44.2CFM fan. That will give you the best possible cooling i think.
