I am looking to replace the stock fans that came with my Lian Li A70 case, which are fairly noisy and don't seem particularly effective. These are 120 mm fans. Does anyone have any suggestions? There are four in the front and one in the back. The back one can be more noisy and have more airflow, however the four in the front should be fairly quiet while moving a good amount of air.

I was looking at http://www.newegg.com/Product/Prod [...] 835185060. It is the highest powered Scythe Slipstream, planning maybe to buy a fan controller with the fans.

Anyone else have any thoughts?

I was leaning towards the Scythe S-flax series http://www.newegg.com/Product/Prod [...] 6835185006

If you buy a fan controller, let us know which one and how you like it.

Late Yoon are supposed to be good too, i was going to get the Scythe S-FLEX's for mine but they are rather expensive over here (AUS) so ended up with Arctic Cooling ones that seem to do the job well.

Are the AC fans a lot more silent and more CFM or just somewhat? Do you happen to know the db level and CFM of the Lian Li stock fans?

Yeh its about the same but im happy with the ones in the case anywho.

Appreciate the info.

I'd get this fan controller here: http://www.jab-tech.com/Sunbeam-5- [...] -2530.html (There's also a silver one)

Then buy these fans: http://www.jab-tech.com/YATE-LOON- [...] -3771.html

Also a good idea to buy some 3pin Y adapter and extenders found in the same site.

If you want something that pushes alot of air get a Scythe Kaze

noctua seem to have come out top in most new reviews gennerally against the S flex. they look kind of funky and they can be expensive but if you want the best...

failing that i would go wiht scythe, if you look on your motherboard to see whether it has a 4 pin fan connecter like that for the CPU cooler, if it does then it support PWM (pulse width modulation) which mean that your motherbaord can control the fan, hotter it gets, faster it spins. i know the scythe do a PWM version of the s flex but i cant rember its name, but i would get one of those if you have the connector

Zalman 120mm Quiet Fan
Model #: ZMN ZMF3

Cost 8.99 on Circuit City site and very quite. I have 12 of these in my case. Free shipping on all order $24 or more. Circuit City has a max 3 order on these.

these fans seem really really promising, no LED's, but they seem to be getting some good feedback... i've been looking at these for quite a while, and i most likely will fill all my cm stacker slots with these by the end of the year

they seem to have better specs than the s-flex

Hmm, those Enermax ones seem interesting. Right now I've been leaning towards 4 S Flexes for the intakes and 1 Ultra Kaze for the exhaust. However, those certainly are in contention.

My buddy just picked up 4 of these for his Cosmos S case, they are absolutely stunning! http://www.newegg.com/Product/Prod [...] 6835214001
They are completely silent even at max speed and move TONS of air! They arent the best looking IMO or the cheapest but these are top notch fans. Buy em and love em!

Edit: I wouldnt suggest a super fast RPM fan because they are really noisy no matter what brand or model and increase your room temp by a few degrees. Stick with the ones I linked they will keep the most demanding system cool (oc'ing to a good degree as well!)

Where did you find this information? I'm looking for the stock fan info for the a05b.

Haha you wanna know how, i bought the case and the model of the fan is written on them, type into google and voila! This info was brought together from a few different places but.

My suggestion would be to either look at ALOT of reviews of the a05b and see if they give you a close enough shot of a fan to read the model number or sometimes they will state it in the review.

EDIT: however, it seems it comes with 2x120mm fans so i wouldnt be suprised if they were the same ones or similar
