Fan selection

post #1 of 10
Thread Starter 
So I have a case with the option for 4x80mm or 1x120mm in the lower front, and 2x80mm or 1x120mm in the center of the back of the case. Would I be better off with 80mm's or 120? And what would your fan recommendations be?

The 80mm's would be too noisy IMO.
If you can find 120mm NorthQ fans - those have epic 80CFM airflow and are quite silent

Hi ronnin

Im always curious at checking out new fans, the ones at northq are all 38cfm, but the ones that are with the cpu cooler are 80cfm, just having trouble trying to find the model no. of the 80cfm. Could you point me in the right direction of model or link where they sell them mate

So those 2 120's would be better than a total 6 80mm? Even at 30CFM the 80's would be putting out the same airflow, and with a positive pressure?

@30 CFM maybe not. But 6x80mm fans will sound like an airport in rush hour.
Tigerpaws, I am also unable to find them separately Will keep searching.

Hmm, ok, I suppose the 120mm would be better for futureproofing too, if I do get a CM690II or something... Yeah, let me know if you find a link for the 120mm fans, otherwise I could go with some GT's when they hit the US.

I think the 1 120mm exhaust would be a good idea, I'm still trying to decide if I should go with just a sole 120 INTAKE or 4x80mm... the 80's just seem like they would pull SO much more air in the case, and I'm wondering how it would play with temps.

also, REALLY interested in fan links... no idea what to purchase.
post #9 of 10
One advice - always place the fans so that the grill is facing the top-side of the blades. Otherwise air bumps and reflects back, + resistance to the fan is heavier => lower RPM.

EDIT: Not sure if I'm express myself correctly here, what I mean is if the fan is exhaust, it pulls more air if it's placed outside the case, so nothing stands in front of the airflow. The reverse for intake.

4x80mm fans WOULD push more air, if you are not concerned with noise, that is the point most people here are trying to make i think, if you don't mind having a relatively loud case then go for the 6x80mm and you could always put them on a fan controller, but if you are noise conscious then go for the 120mm
