H440 Fan Placement

savagesam117 · 27 Jul 2015 at 22:03

I'm thinking about switching my fans about because 1, my H105 isn't cooling as well as it should be, I know it's never going to be great in this case.

I currently have two AF120's in the front, two SP120's on my H105 in the roof and then the standard 140mm in the rear as I can't be bothered to change it.

I have them all plugged into the 12v thing that comes in the case as again, i'm too lazy to route them to the Mobo.

So thinking of taking out one of the AF120's and putting my 240mm H105 at the front as an intake and then an AF120 at the back as an exhaust, which would create positive pressure in the case am i right?

Yeah try that but stick the two AF120s as top exhaust with one of the included fans.

Or you could try getting better intake fans as AF don't have the required static pressure to go through the front of the case.

I'd try the former first though so you won't have to spend any money if it works

Well i've also got a spare pair of sp120's i could swap out for the intake or wherever?

I would keep the aio water cooler in top as form Christ but try your best to incr see the intake air. Try the sp's at the front blowing into the case. Doesn't that case come with 3 front fans? People keep saying the vents at the front are not sufficient for airflow so some sp's would be better I imagine.

You can't have the aio water cooler as front intake as its all you have for intake. It would make the air inside the case pretty hot/warm for the rest of the components in a case with such poor airflow (if what people say about the airflow is correct).

In short;
- kelp the CPU cooler at top as exhaust.
- use some sp fans at front for intake.
- keep the exhaust at top/rear as an airflow fan.

This might get better with some better sp fans ie noctuas or vardars.

Cant you just swap the aio fans from push to pull,suck cold air from the outside through the rad and exhaust it out the back?

It doesn't bother me that much to be honest, not worth buying more fans that'll make it a little bit better. It doesn't get realllyyy and my 980Ti is reference so that throws heat out of the back.

It does yes but I got the case from the MM brand new with no fans apart from the back one, i could put another fan in the top and front.

Yeah I could do but then it would look ugly

Well it wouldn't hurt if you used the extra sp's you have in the front and add another fan to front as well what ever it is - sp or af. It would still decrease temps.
