Hi Guys

We are proud to announce for pre order and due to land any day now, the superb new eLoop fans from Noiseblocker.

Noiseblocker is one of the most premium and advanced PC fan manufacturers in the world and their research goes leaps and bounds above the competition in the quest for a silent PC.

I use Noiseblocker Blacksilent fans in my own system and if they are anything to go by, then the eLOOP range is looking set to take the PC cooling world by storm!

RANGE HERE

Are you sure the noise levels of 20-35 dBA are correct? That's louder than Noctua's, and substantially different from the 7.83 dB (A) for the Noiseblocker NB-eLoop Fan B12-1 - 120mm.
 
A bit of googling brings up these specs, dunno how reliable they are tho -

B12-1 : 800rpm, 7.83 dBA, 57.3 m³/h
B12-2 : 1300 rpm, 16.7 dBA, 86.9 m³/h
B12-3 : 1900 rpm, 26.5 dBA, 121.2 m³/h
B12-4 : 2400 rpm, 34.3 dBA, 150.3 m³/h
B12-PS : 400-1500 rpm, <21.2 dBA, 98.7 m³/h
B12-P : 800-2000 rpm, <28.4 dBA, 132.4 m³/h

20 - 30 dB(A) is a hell of a lot for a fan. Bearing in mind the dB(A) figure is a daily average
 
That's why there is a range of speeds.

No 2000+ rpm fan is going to be whisper quiet.

These are designed to be used for multiple applications.

You want to a quiet fan? Go for the 800/1300rpm models
You want performance and airflow? Go for the 1900/2400rpm models

For cpu coolers and everything requiring motherboard control, there are pwm enabled units with a superb speed range to allow maximum user adjustment

Or you could always do what I have personally always done and get fast fans and put them on a controller.

For example, our most popular fan for Watercooling is the 1850 Gentle Typhoons, this isn't because they are quiet but because they are fast and push daft amounts of air at full pelt. Put them on a controller and they will happily run at 400rpm and make no noise at all whilst still pushing the more air than most other fans.

As for a 140mm eLOOP, "nothing has been announced yet but I will contact noiseblocker a d see what they say.

Well put. We could do with a guide to what the best fan options are.
 
Those look very different whats on the market IMO, tempted by them, especially as I've had Noiseblockers in the past, do like them!
 
looks like they have licenced the 'Bionic Loop Propeller' design.

AP-14 , 1850 rpm , 26.? dBA , 98.5 m³/h , 2.0574 mmH2O
B12-3 , 1900 rpm , 26.5 dBA , 121.2 m³/h , 1.997 mmH2O

AP-15 , 2150 rpm , 30.? dBA , 117.2 m³/h , 2.8702 mmH2O
B12-4 , 2400 rpm , 34.3 dBA , 150.3 m³/h , 2.741 mmH2O

from here and here

dBA was measured at a meter away

So in summery
GT's give slightly more static pressure
e-loops give more (unrestricted) airflow

Low FPI rad / Heatsink - the e-loops 'should' be significanly better (but a bit louder at high rpm)
High FPI rad / Heatsink - slightly better, but needs testing

Also the GT's have a woosh noise - which is easy to ignore (so you think it's silent)
No idea what the e-loops noise signature is as yet

Measured results on a rad, dBA next to fan - martin's liquid lab (link above)
AP-15@12v , 1780 rpm , 41.7 dBA , 112.8 m³/h
(datasheet) , 2150 rpm , 30.? dBA , 117.2 m³/h

M12-S2@12v , 1290 rpm , 41.1 dBA , 72.8 m³/h
(datasheet) , 1250 rpm , 19 dBA , 87 m³/h

LOL, probably a mistake?
