Where to get foam air filter? Installing side fan(and hole)

boe · Post by **boe** » Mon Oct 01, 2007 8:15 am

Hello,

I have built a system with four SAS cards and a video card - the sas cards run very warm. The case does not have a side hole for cards - I want to install one. I figure I should use a foam air filter over the hole as the area is usually dusty. I have no idea where to get thin form for filtering.

Depending on the size of fan you want to drill a hole for, you can get pre-made 80/92/120mm fan filters + holders for next to nothing. E.G. :

You can also obtain metal mesh filters which work fairly well for larger particles like hair:

Thanks so much! Now onto the search for the most powerful 120mm fan

That's easy.....Here it is. Just be careful your foam filter doesn't get sucked in.......or your dog.

Dang! That is impressive - not sure I have 76mm of clearance above the cards though - I'll have to measure as soon as I get a chance.

And only 59db! That's what I call silent.

Hmm... it claims to have an unbeatable CFM/dB ratio. Has anyone tried undervolting this thing?

22cm fans typically have 100CFM/20dB. So 200CFM/60dB is not unbeatable, especially considering that 20dB is wayyyyy more than 3 times quieter than 60dB. Someone else could probably expound on undervolting (I don't know the equations that apply)-- I'm guessing that it's not worthwhile.
