EK-Vardar is simply the best choice for computer radiator cooling as it provides unmatched performance throughout entire operating range. The key characteristics of EK-Vardar fans are: High-static pressure / low noise profile - unlike other general-purpose computer cooling fans, the EK-Vardar family of fans is built specifically for computer liquid cooling systems, namely radiator cooling. The 7-fin fan blade design is optimized for high pressure operation while maintaining the low noise profile throughout the whole operation range of the fan. Vardar's design and construction is also very suitable for high-performance heat-pipe air coolers. High-quality motor and bearing assembly - Proven electrical design, actively cooled motor windings and Double Ball bearing with 50.000 hours lifespan (MTBF) ensures uninterrupted operation for years to come. Phase-width modulation (PWM) fan speed allows performance on demand. Sealed-edge fan casing - The classic, yet effective square shape of the fan casing ensures optimal performance in either pull- (suction) or push (pressure) regime without hydraulic losses thus ensuring optimal cooling capacity of your liquid cooling radiators. Timeless design - the EK-Vardar fan fits subtly into any liquid cooling computer without drawing too much attention. Single- and two-tone colour design with monochrome fan sticker. Less is more. Mechanical and electrical specifications: - Speed: 1850 rpm (+/- 10%) - Rated Voltage: 12V DC - Power Draw: 1.44W - PWM Duty Cycle: 50-100% - Connector: 4-pin PWM header - Shaft bearing: Double-ball bearing - Bearing durability: 50.000 hrs @ 40°C (MTBF) - Dimensions: 120 x 120 x 25 mm Performance characteristics: - Max Air Flow: 63 CFM = 107 m³/h - Static Pressure: 2.24mm H2O = 22 Pa - Sleeved cable length: 300 mm - Noise Level: 29.5 dBA

Silent Fans (Seriously)
I decided to take a gamble and purchase these fans after watching the JayzTwoCents review and and am very glad that I did. I replaced the two stock SP120 fans on my Corsair H100i. Even though these fans only have a max speed of 1800RPMs they are able to maintain better overall temperatures compared to the stock fans which run up to 2500RPMs. By default they sit around 1100RPMs and are are almost silent. Even at maximum speed these are some of the quietest fans I have ever used. Good purchase and will definitely be getting more in the future (Will go with the F5-120s for the higher speed when overclocking since they are so darn quiet).

Nice fan quiet and good design the box they package ...
Nice fan quiet and good design the box they package it in needs to be redesigned it tore up getting fan out of it. it comes with the standard case mounting screws that confused me a bit as I thought this was for mounting on water blocks and would need longer screws. I just used my old ones i had from other fan. I thought there might be a bit of a improvement in cooling but it was only a degree or 2. I ordered someCoollaboratory Liquid Ultra Thermal Paste that is supposed to make a big difference in heat transfer. I hope it can get cpu down 10 or more degrees. Check my feedback on the past in week or so to see what improvement i got. will try to post on it next weekend.

Perfect for multiple uses.
I bought these fans as intake for a restricted case (NZXT H440) to improve airflow. The static pressure improved the interior temps by a solid 9 degrees C over the stock intakes. These are not just for radiators, they are a vast improvement in any situation where airflow can be restrictive; and good static pressure like this is the solution. Even getting up into the higher RPMs these were relatively quiet (especially in comparison to the stock fans) and unless I'm stressing my system quite a bit, I never hear them.

Just what I need for my watercooled rig
The FAN IS SO SILENT! Best fan I ever purchased

Will buy it again
Super quite as advertised.

Less is more.
I returned several other fans I bought so I could buy a few of these - and they are indeed silent and wonderful. Love how quiet they are. Even when I crank up the RPM's in the BIOS, they remain fairly quiet. About to water-cool the crap out of the computer and looking forward to these being the primary fans on the RAD.

good fans.
good fans... the best! buy them for your Radiators...... not your everyday air cooling....(you will be wasting money) trust me!

Great mid-speed fan
These fans are only half the volume of the stock fans that came with my radiator. Great mid-speed fan.

Highly rated!
Fitted two of these to a Corsair H100i v2, and it has made a massive difference to the sound - can run these at 100% rpm and they're quieter than the stock corsair fans at 20%... definitely recommended!

EKs excellent quality shines with their fans too!
Nice and quiet, good airflow, great look, excellent quality, what more can I say!

Good quality
Very quiet for a cpu fan but has good performance. I would go for a higher rpm though since these are very quiet why not have some more performance.

Excellent fans swapped out from Corsair SP120'S on my 240mm radiator I can't even hear them :) temps are good on a i5 [email protected] ghz

great, had to replace a old fan, this is quite with good air flow
