Meh, I don't consider it to be threadjacking.  Cooler Master BladeMasters (120mm x 25mm) actually have a static pressure rating of nearly 4 mmH20.  Those H70 fans have poor pressure if I do say so myself.  The thing is, the BladeMasters won't necessarily be quieter.  They too are 2000 RPM sleeve bearing fans.  However Cooler Master should be releasing their hydrostatic bearing BladeMasters - the ones included with the V6 and V6 GT.  But where are they...

The San Ace 9G1212H4011 (120mm x 25mm) has a 40 DBA rating with a static pressure of over 6 mmH20 if you're interested.

Now we're talking. I'll have to see what Santa brings me for Christmas... if there's cash involved, this might be something I pickup!

nice info!!!
 
wish there would be slim case fans like 120mmx12mm with LEDS.  would like the scythe slim fans but they don't have LEDS or colors hehe

check the info on the sythe fans,i have 3 of them 120x38 they worked great for the first 3 months,now i am junking them.temps have risen.do not know if it is the fans or my house temps.but it was hotter in the summer.

Dust build up would be my first guess.  I have one of these coming tomorrow.  It will be used on my Thermalright Shaman.  I'm eager to hear it.  I expected my Panaflo U1 120mm to sound loud but my GTX 480's stock cooler is much louder.  That fan coming tomorrow has a similar DBA rating.

"It also has an amazing near 3:1 airflow to noise ratio."
 
best quote ever for a fan...

Useful in some scenarios yeah.  There are some new 120mm x 25mm LED fans out on the market.  Silverstone AP121s now have LEDs.

They have also released the AP141.  I'm liking the CFM rating compared to the AP121.  Static pressure is slightly lower but I have use for one... or two.

oh i love those air penetrator fans.  gonna buy those if they sell on newegg.  thanks for sharing.

boregunner,thank you for this thread.i have learned a lot from this,i thought more cfm was better before did not know about static pressure.and after reading this i have ordered 6 panaflo fans and a sunbeam controller.

Glad to help and nice choice.  Added a section on fan blade design to the OP.  I ordered that Nidec VA450DC nice and smooth.  $13.50 + $8 shipping.  Can't wait.  My first > 64 DBA fan!

Little update that might interest some of you.  Websites that offer Delta, Nidec, Sanyo Denki and other server grade fans for a lower price than you may expect.  Just remember no connectors are included.  Just the sheathed wires so you must add the connectors yourself.  

• OnlineComponents - Excellent supplier for Delta fans.
• MPJA - Variety of rare fans, best site I've found for Nidec fans.
• Newark - They have tons of Sanyo Denki fans.  To simplify and shorten your search, click here for a list of 120mm x 25mm fans, here are their 120mm x 38mm fans, here are their 140mm fans and you can find other, odd sized Sanyo Denki fans such as 150mm and 172mm.
