The 140mm (14cm) version of the Aerocool DS Dead Silence fan ships in a clear plastic packet with the product clearly visible from the front. This red coloured version looks great, and Aerocool highlight the other colours underneath the window.
The rear of the packet highlights the specifications of the unit.
Inside the packet is a 3 pin to 4 pin adapter, a 7V voltage reduction 3 pin adapter, 4 screws and 4 rubber rivots.
The Aerocool DS Dead Silence fan in red is beautiful looking and nicely finished, comprised of 9 fan blades. This would look great in a red chassis from the likes of Lian Li or NZXT.
The fan measures 140mm x 140mm x 25mm and weighs 190g.
This Fluid Dynamic Bearing (FDB) fan is rated at 12V, with a starting voltage of >3.0 V. It is rated to demand 2.4 watts of power (same as the 120mm version on the previous page). The voltage reduction cable is included, which steps down the demand to 7V. The rear side of the fan blades incorporates a ‘fish eye' design to help reduce turbulence, lowering noise levels.
The construction quality of the fan is very high, and it is immediately noticeable all of the fine attention to detail, even on the corners of the unit.
The blades of the fan are made from a combination of rubber and plastic which is aimed to reduce turbulence and noise.
On the exhaust side of the fan, Aerocool have sculpted the plastic to help concentrate and direct the airflow.
The Diagram above explains how the air is concentrated and forced through, using the concentrated airflow principle.

Aerocool have incorporated a lot of noise damping design into the fan. Each corner has a ‘Silencer' which can absorb and reduce the noise of the air passing between the blades. This anti vibration pad is also designed to reduce vibration caused by the spinning blades.
The image above shows how the Silencer operates, taking the air and interrupting the flow to reduce noise.
The Aerocool DS Dead Silence fans are fully sealed to stop the lubricant from leaking.
Fluid Dynamic Fans by nature are more robust than traditional Sleeve bearing, or Ball Bearing units. They are fully lubricating, with high anti shock characteristics and have a life span in excess of 100,000 hours. A standard sleeve bearing fan by comparison would be rated between 30,000 and 50,000 hours maximum. The oil way in the center area of the shaft keeps it lubricated. Lower friction also helps reduce noise and temperature, enhancing life span.
Very pretty fans, I like them. I can’t find them anywhere to buy – like a lot of stuff you guys reviews 🙁
Try CCL, they have stock 🙂
Ordering 4 for my NZXT chassis. dont like the standard fans in it.
Going to order a bunch at the weekend – PAYDAY!!!! good looking fans too, look wicked. awesome.
We will have some stock available later today…

Price is quite good at CCL, will be picking a few up for some ‘trials’ will share my findings over on the Kitguru Facebook page in a few weeks, all being well.
Shame I didnt get some good high res pics of the blue fans. im in the middle of a mod on my corsair case which I shared on Facebook , those blue and black fans would work a treat. Also, congrats to Aerocool on adopting FLUID DYNAMIC BEARINGS, I used to own some of these fans and they lasted for years and outlived my system. fantastic.
ordered a red and a white. will post my feedback later. seem high tech and I never rated aerocool that highly, although I like their dead silence case a lot.
Are they better than BeQuiet Silent Wings 2?
I’ve been interested in upgrading my 140mm fan, but have been divided between beQuiet and Noctua. However with the designs on these I would like to know how they all compare especially since I’ve been told Noctua is the top but have a horribly ugly colour scheme.
Hello. It is unfortunately difficult to compare fans such as Noctua v BeQuiet! v Aerocool. as the limit of our noise monitoring equipment is 28 dBa (which is basically ‘silent’ in the real world). Most of these fans are rated below 20dBa and we just can’t accurately produce noise graphs for these without highly specialised equipment. Rest assured, any of these leading fans will produce fantastic results in a variety of situations and a lot of the buying decision will probably be made on appearance. Noctua obviously have a massive following even though many people class them as ugly looking.
We could try and follow up with a cooling performance article comparing the leading fans, but time right now is very tight in regards to overall review demands.
Great looking fans! I am going to replace my noisy H60 with one of those. One question: My H60 fan is connected to the 4pin CPU fan socket. I understand the Aerocool DS fans only have a 3 pin, meaning there is no RPM control from the system. Does it matter? (As this is my only CPU fan)
Get a 4-pin Y splitter socket.
Thanks! I run it on full speed @1200 for now. It is much quieter than the H60 and gives me more flow, as the H60 was regulated to around 1100 by PWM.
Just installed 2 of these fans in my computer and amazing. My temperature has even dropped a little.
Mine did not last 6 months mounted horizontally, of the 6 purchased 4 rattle noisily at mid rpm, and one even developed a low frequency vibration that I could hear/feel throughout my entire house.
All reviewers mention that you should not use the horizontally. If you use them on an AIO radiator, set it up in front of your case as intake. Horizontal setup will destroy these fans. I guess all the noise reduction engineering has its flaws.
