cm 90cfm/19dba label is just a marketing bulls***....
its noisy (heck its cheap though)..
imagine if u put 3 fans inside your case...
sure the sound like screaming hell...
even with 1 fan... i couldn't even stand it. arghh!

You guys have sensitive ears

I have 4 fans in my casing now..not really noisy lol..
Most probably coz I on my speakers loud and the surroundings isn't quiet..

im using 3 of the fans now.all as intake fans.the noise is acceptable for me.the stock fans included with my CM690 are louder.so,im quite satisfied.plus, the air flow is great for me also.

but i wish i can have delta fans.wahaha =x

Hmmm, last year I use 2 of this fan, but now got 1 "cabut" .... Don't know why like can't turn, although clean those dust... It look like old time fan turn very very slow....
And 1 more thing is... this fan can't add oil in bearing there... because of all is close by the plastic.

Same thing happened to me..I've already sent it for warranty lol

i have 3 of these as intake and 1 of these as exhaust, another 2 standard fan that came with my cm-690. just dont put these babies on the upper grills.

actually these fans are quite good and silent, i have 2 on my TRUE and 1 as an exhaust with another 2 type of other fan on my top, i could sleep pretty well without hearing any sound problems =), push a lot of air too

these are with load temps, Prime 95 small ffts =) with ambient 25-27C..

second one are from intel burn test =X

The code number at label for 90cfm and 69.90cfm is exactly the same..

Nope..

Check it yourself...
90CFM
69.69CFM

but still the same 2000RPM, 0.35A, 4.2 W ± 10% and even the same shape and design....but magically it got 90 cfm!?, how come, tell me now....the LED somehow produce 20CFM?....lol

I use 5 of these fans in my CM590 (with window) casing (2x top exhaust, 1x rear exhaust, 1x side panel intake, 1x HD cage intake). Fan speed controlled automatically by mobo (temp controlled) and Aerocool fan controller. 5 fans running at the same time is quite loud. Not the high-pitched whine common with high-speed Delta fans, but just a general loudness. Luckily for me that rig sits in a spare room with another rig (which is very silent due to silent fans + sound proofing materials). So I am rarely in that room. The rigs run 24/7 (folding@home, and DVD ripping from time to time).

Due to the high volume from many fans, I've decided to only use 1 or 2 of them (for intake) in my 2nd CM590 casing. Will use the CM140mm fans as exhaust, along with CM's UV reactive 120mm fan (the casing will have extensive UV lighting scheme), and a 120mm Panaflo (more CFM than this CM "90CFM" fan, based on unscientific personal "hand feeling" test), plus CM's 120mm silent fans for the rest.

On their own, I would say they are relatively quiet. It's just that once you have many of them together, plus 2 other rigs in the same room with multiple fans each, every little bit of sound adds up and the result can be loud.

if you want a cheap fan...this izzit, for RM25 such a coolooking fan is kinda ok.... but surely its not a very quiet fan and definitely not 90cfm like they claim....so your choice really...like they always say here...if you want a high cfm fan go find yateloon or silverstone on panaflo etc etc....

so its safe to say here its a FAKE

hmm yateloon is my choice. but if cant find it, i'd prefer xlf's over coolermaster

if you think about it, since the yateloon its hard to find, the silverstone price just to high and the panaflo, delta is not coolooking enuff...this fake 90cfm fan is still kinda good cuz the alternative to it was XLF and Vizo starlet and hmm and tats about it i think, other brand its hard to find, at least in lowyatPlaza....

Both of tat fans above only produce 62 cfm while this fake 90cfm produce near to 70...i do handtest between XLF and this fake90fan and clearly this fake fan pushing more air...so dow its fake its still kinda good...its cheap somemore...

I thought YL fans are make much noise compared to this 90CFM fan..no?
How much is a good YL fan and usually how much dB is considered quiet?

PM bryanyeo87,he can obtain yate loon from low speed to high speed
I have my high speed from him
Well use as intake is loud but good

if u really want a 90CFM at low dBa rates liao.. imo theres a fan called Ixtrema 120mmx38mm 90CFM 18dba fan liao.. it spins at 1.4k rpm and cools very effiecently..

never heard of this brand and how is the price and wher can i buy it?
