Strong quiet fans - Page 5

You mean take out ALL the expansion slot covers?

reverse airflow can actually work out pretty good, so I don't see anything wrong with keeping that rear fan as an intake so long as you have a top exhaust mounted above/left of the cpu cooler. Just keep it to a single top fan, though. I wouldnt put one on top over the rear intake.

if you mounted the cpu fan to intake from the interior, exhausting out the rear, it may get some warm air from the gpu but much of that gpu air will be carried out the back before it can get to it, and whats left over will be mixed with the cool air coming from the front intakes. Shouldnt harm cpu temps, really. Both methods can do well if tweaked right.

I would recommend a slower 140mm fan like a TY-140, Scythe Kraze Maru, or even the Noctua NF-P14. The temps of your GPU might not be as low as using a strong 120mm fan, but your overall temps might be lower. - especially that of your CPU. A strong 120mm fan is only going going to blow the hot GPU air all over your case. You just want a fan to help move a bit more cool air into the case and let your main fans concentrate the hot air out of the case.

For a shroud, all you do is take a junk 120mm fan that you don't use and cut out the inside, screw it to one side of your R4, and attach to mesh. Many a good working fan has made the shroud sacrifice for my builds.

Oh, yeah I have the same 120 sickleflow, broken, I could use that, but that would make the side panel fan come very close to the GPUs, making more noise since it would blow air RIGHT on the gpus.

the shroud would be attached to the exhaust side of the fan, not the case panel, to help focus the airflow. sometimes it helps, sometimes not.

OHH

So like this going from outside to inside:
Panel - rubber pads - actual fan - shroud - gpu - mobo - other side panel - wall - other wall - house across my street - other house - around the globe - back to my side panel...

well for that you're gonna need a much, much stronger fan.

OKAY so if I change to this setup: front intake, side intake, top intake and only back 120 exhaust, that would make it so I have positive pressure right? And I would than have my all this hot air in the case floating around.

Oh yeah lol, but that's how you meant right? at the end of the fan, not between the fan and panel.

yah. It's like an extension for the fan, to funnel the airflow. Fans usually have airflow that goes wide. Think of the current fan as a sawed off shotgun, and you want to lengthen the barrel so you can hit the target instead of blasting the entire wedding reception.

Genius!
Yeah will try after I come back from school, damn 4th grade is tough! helmetsmiley.png

anyone gave this fan
http://www.newegg.com/Product/Product.aspx?Item=N82E16835226013

says 90cfm!!!! At only 18db, but a lot are complaining that it is much louder than that. So I am stuck between the cougar, the r4, once I put in the shroud, and the new fan linked up there.

does anybody have that silenx?

ohh what about this? Any good?

quite and strong.
