Fan's dust filter airflow problem.

[ClownWalker]

Hey guys! Here's the problem : I just bought a fan filter AND ''airflow enhencer'' and I don't know which side of the fan I'm suppose to mount/screw it.
It's the FF121 Silverstone Fan filter : http://www.newegg.ca/Product/Product.aspx?Item=N82E16811999217 . The website of the product does not give any instructions about the installation. There's only two ways of installing the product on my 120mm intake side fan :

1. On the inside of the case : http://cdn.overclock.net/8/81/600x400px-LL-811a21ba_IMG_5118.jpeg

OR

2. Outside of the case just before the air comes in : http://cdn.overclock.net/7/75/600x400px-LL-75f5d7e8_IMG_5143.jpeg

Also, this is how it works : http://t0.gstatic.com/images?q=tbn:ANd9GcRs8Y50nwxtswmw6NViENSPAj2xIKmoBeVhYM-APC9l9H69k6XR0wBTdZMv5g

So what do you guys think, as it's an intake fan, should I put the filter at the outside of the case so the dust, hairs and particles won't go through the casing? Or should I put it inside?

it would be preference. outside or inside the filter will work the same. and for most fans looking at them the NON moter side is generally the intake. the question is do your want to see it? and do you want it easy access for cleaning.

if you dont care to see it and want it easy access then put it on the outside.

if you do care to see it but dont mind about the easy access to clean it throw it on the inside.

for me it would depend on the case... if it was an awesome looking case the filter would be inside....

Well, I don't really care if it's outside since my case is the Antec Three Hundred Two : http://images.thoughtsmedia.com/resizer/thumbs/size/600/wpt/auto/1327469163.usr117680.jpg

I only care about the performance of the filtering and the airflow focusing.
