Case fans for the front?

post #1 of 14
Thread Starter 
I know this gets argued all the time, and I'm reasonably sure this will just end up with people being divided.

Anyway, what fans are good for the front? Static pressure or air flow?
I've got the Corsair Air 540, there aren't any obstructions in front like HDD cages, it's clear all the way through. However it has to pull the air through the mesh at the front.
My understanding of why static pressure fans are good, is because the blades are really wide, which prevents air being pushed back through in the event of something dense being in front of it (radiator, HDD cage etc). Where as air flow fans, have gaps between the blades, which will allow air to hit the cage/radiator and force itself back through the gaps in the fans.

But, people argue that static pressure are better with mesh too, I just don't understand how/why. Because it'll be pulling the air through the mesh, but nothing will be obstructing it on the opposite end, so no air will then be pushed back through?

Anyway, I just want opinions on what you guys think are better for front fans, with mesh, but no HDD cage or anything. Also, if you can state whether your opinion is based on preference or actual facts?

Air flow/CFM more so than static for intake,however if your case has say 2 intakes you can run lower noise/less CFM fans.The amount of CFM need not be excessive for intakes,i personally would get the highest CFM fans you can find in a dB range you will be happy with and can afford.The amount of intakes usually outnumbers the outakes and so you need not worry about buying noisy and expensive fans.Try to get some Fractal Designs,noctuas or be-quiets

Just noticed your case your using.You will be fine with low noise moderate CFM fans,especially with no obstuctions.thumb.gif.

* Static Pressure is how hard fan can push air agains restriction/resistance... how many mm H2O high in the tube when the air stops moving... Static = stopped, still, not moving... not very functional in real world.
* CFM is how much air will flow with no restriction/resistance... and the rating is based on no resistance... on top of a clean bench... not very functional in the real world.
* Now say a grill and filter has 0.4mm H2O resistance.

Take a fan with 80cfm and 0.8mm H2O with a grill and filter in front of it and it flows 40cfm.
Take a fan with 60cfm and 2.0mm H2O with the same grill and filter and it will flow 45cfm.

The fan with higher Static pressure specification will flow more air when there is more resistance even though it flows less air with no resistance..

Fire some Noctuas on there, can't go wrong. You won't need the F series ultra performance radiator fans for case ventilation, the usual NF-P12's will do you just fine, or if you're not into that colour scheme, something similar. Noctua fans are the best built I've ever used though... The only non Noctua fans I run are 6 Gentle Typhoon AP-15's on my radiators. They're ugly as hell but they push air through rads like nothing else at their volume level. That's when static pressure really matters.

Yeah, that's how I understood it. However, it'll be pulling air from the mesh, not pushing it through the mesh. People seem to suggest static pressure fans for this, but I don't understand how that'd make a difference.

As much as I'd love to have the Noctuas or something in there, I simply couldn't . Ha, with the Air 540, it's got the windowed side panel. I don't think I'd be able to bear staring at those things all the time. I've gone with the Corsair fans, not the best performing, but they look awesome.

It doesn't make much difference if fan is pulling or pushing.
Static pressure rating is the difference in air pressure between air in front of fan and in back of fan.

If you have a HDD cage right behind the intake (or dense filters) then you need decent static pressure fans. The Carbide 540 is probably the opposite of that.

Someone needs to review the all-black Prolimatech Ultra Sleek Vortex (slim 15mm thick fans , 140mm frames with 120mm mounts)... it's pricey though http://www.newegg.com/Product/Product.aspx?Item=N82E16835242033

But other than that, Phanteks and Thermalright TY-147s are a good bet for color choices.

If you buy AF140s I don't think you'll see much improvement over the AF140L that is included.

If you're looking for black 140mm some okay options are:
Various fans for radiators : Phobya, Koolance, XSPC, etc
~$10 Cougar Turbine (not Hydro dynamic bearing... hyper spin bearing gimmick)
~$13 retail Rosewill Hyperborea http://www.newegg.com/Product/Product.aspx?Item=N82E16835200067
^ I have no idea about this one, Tater Tot says it is indeed a hydro dynamic bearing unlike the 120mm version which isn't even if they say it is
~$16 retail Cougar HDB http://www.newegg.com/Product/Product.aspx?Item=N82E16835553007
<-- Corsair AF140 goes here. Not a lot of static pressure as far as I know. Quality control isn't that high either.
~$20 Prolimatech Ultra Sleek Vortex
<-- (Overpriced) Noiseblockers
~$30+ (Overpriced, due to limited US distribution) Be Quiet Silent Wings 2 140mm

Black and white:
~$13-16 Thermalright TY-147 -- 120mm mounts, decent static pressure as well, can be (and is often) used on heatsinks smile.gif
~$10-13 Arctic F14 -- decent static pressure https://www.superbiiz.com/detail.php?name=CA-ACF14 , $5 OFF your order over $25 w/code:SUMMERSALE
~$13 Gelid Silent 14 , quiet but less airflow than F14s (~$11 Swiftech Helix goes here too)
~$15 Fractal Design Silent Series R2 140mm
<-- NZXT 140mm FX-140LB fans go here
<-- (Expensive) Noiseblocker eloops
Phanteks PH-F140XP (unreleased) --> meant more for rads

I know that alot of people are using the cougar vortex pwm fans, you could check those out for airflow
post #9 of 14
I see vertical plastic bars, a honeycomb grill with not too large holes, and then some choking fine mesh:

carbide-air-540-19x-1280x1024.jpg

If you are not removing any of those restrictions better get decent fans with good static pressure.
