Case cooling

[Dawelio]

Heya lads,

So I have a bit of an concern here... I've recently purchased the Corsair 350D and I also got 2 x 140's Fractal Design Venturi HP PWM's fans.

Now, my idea here is to have these 2 in the front as intakes... 2 x SP 120's on the H100i in the roof as exhaust and one 120 AF in the back as exhaust.

Considering my 980Ti is an reference, blower style cooler, it's also an exhaust.

So then this leaves me with 3 x 120's as exhaust and 2 x 140's as intakes... my concern is that this might be too negative pressure?.
As I'd like to have the rear as exhaust, due to the graphics card pumping out hot air at the back and then if the rear is an intake, then it will most likely suck all that hot air from the GPU into the case again.

PSU will be upside down, fan facing into the case. Although, it hardly ever spins.

Any help, ideas, recommendation here is highly welcome!

Regards,
Chrazey

The HP fans are meant for static pressure, the HF fans are the air fans. You should be fine though. I'd run everything on 7v tbh and you won't hear a thing.

Yah I know that, but considering the front part of the 350D is pretty much a plastic plate, the cooling is restricted. Hence static pressure fans for the best possible cooling.

Not sure how much 7v is on those, as I run all my fans off my Corsair Commander Mini for software controlling.
Thanks for the tip though NBD!

I don't see anything to be concerned about, negative pressure will not cause the world to end. Worst case situation it will probably be slightly dustier but i'm sure you clean your PC anyway.

Using SP or AF optimized fans won't make much of a difference in the front of the case, the cases really aren't that restrictive. Just because the air doesn't move directly perpendicular to the fan intake doesn't make it a problem. Having said that most SP fans have decent airflow anyway so the difference is going to be negligible.

Just throw it all in a rig and stop worrying. 350D's are one of the prettiest Corsair cases IMO. I wouldn't recommend using the floor mounted fans, they seem to make things a lot louder.

I'd say you could even remove the rear exhaust fan entirely and then you would essentially have a positive static pressure due to the 2 x 140mm in front, and the 2x120mm in top. This does of course require that the intake fans push in more air, then being pulled out in the top.

Test it out and see what suits you best.

Edit: You could use that left-over fan as an intake at the bottom, if there's room for it.
