Air Flow in PC CPU

[aaaflyer]

Carbide Air 540
3 intake at the front,
2 exhaust at the top,
1 fan set to push for h60 rad.

Simple... positive airflow.

Just wondering if it is possible to put 2 fans at the bottom where the hdd and ssd are? though there are no mounting holes on the air 540 itself.

the question is for 2x290 crossfire to increase air intake. the bottom fan can blow air directly into the gpu.

so 3 intake front, 2 exhaust top, 1 exhaust top, 2 intake bottom

No, the trays are on the bottom panel itself. There is no allowance to put fans under them. Also, there are no holes for the air to go in.

Your front most bottom fan should be able to feed air into your gpu. The middle fron fan also can help. best to get high CFM fans for your front case lor.

Wah please do not use that fan.

It is not that silent as you think. lol

It is damn audible. Even with silencer.

Jetflo isnt strong... AF120 should be better..

Your top is occupied by 2 fans. Presume your h60 is intake of air as push?

Depends whether u wan make it exhaust or intake. But your rear mus be opposite of your top.

Lol, they had silencer???

They had. And yet still noisy at 1650rpm.

Jus watched youtube for it... Similar to noctua ULNA and LNA...

Jetflo 90 plus cfm.... Af120 only 60 plus leh haha. Or am i wrong....

Anyway i dont have that aio.... I use nh d14. So i not sure if there is a need for top exhaust. Will it help much?

Jetflow sia... Means blow like a jet ma. Silencer is not applicable here lol.

Anyway getting it because i thought it will still be silent compared to 290 crossfire?

Since u uding D14, best to set top as intake and rear as exhaust. Reason is that for your D14, air is flowing from right to left. By making youe top as exhaust, it is taking away the air meant for your cooler. Also if your rear is intake, and your D14 is pushing air into the rear, there is a conflict.

FOr your case, set rear to exhaust out the hot air frm your D14. Set top to intake. It will give more air for your D14.

I see! Much clearer now thank you!

So is af120 better than jetflo? Or u meant like overall performance af120 is better taking the noise into consideration?

AF120/140 is good for airflow in unrestricted areas such as the open area in your 540. No hdd cages blocking the airflow.

Dun just look at specs nia, some brands may overspec it.

Just nice af120 amazon is at lowest 13 dollars!

Singapore can get for $30 for two AF120 LEDs. Look around the buy/sell section.

i agree that they are noisy.. i use the 1200rpm adapter for it..

It is better to have a higher positive pressure instead negative pressure, dust will tend to find tiny holes and get trap inside the case when there is negative pressure.

To find out the pressure, you just have to add the CFM intake and subtract the CFM outtake of the fans. If you are having identical fans, than you should have one more intake fan to generate a slight positive pressure.

 

[MevolutionX]

I feel a need for static pressure, the front of the air540 is obstructed by fan filter & the vented cover.

Most of the time the fans are running at the slowest possible speed anyway except the h60 pump which is at full speed. I have a fan controller now. No noise at all

Take note though, each channel support 12W or 1A only... So dun overload each channel.
