Below link is basic guide to how airflow works and how to optimize case airflow. Setup case fan speed curves to cycle with cooler fans they are supplying air to so the air temp going into coolers is only a few degrees warmer than room, especially when components are working hard / near 100% load. It's nice to have some extra airflow available even if it's rarely used and of course louder if needed.Ģx 140mm in front and 1x 140mm in bottom with all openings not covered by fans blocked of so air they push into case has to move through and out back, not leak around and be sucked into fans. I say the high speed (1600rpm max) because the other option tops out at 1000rpm, which is enough for 99% of our uses, but gives us no additional airflow for extremely hot weather, dirty filters, etc. If price does not make any difference the best fans I know of are be quiet! Silent Wings 3 140mm PWM High Speed. Neither is a way we use our fans, so specs are not really the best way to determine a good fan. Noise level rating is usually only a pressure rating in dB, so does not take into account if sound is good or bad to our ears.
When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.Static pressure rating is how much pressure in mmH2O fan at full speed can make pushing air into a sealed container.
Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.Īnother avenue to explore is the possibility of using a bay-mounted fan controller. The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection.
The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. Screw hole spacings and fan sizes 32mm between screw holes:Įlectrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally. If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. If you have any questions about which fan you should order, please don’t hesitate to get in touch. All our fans are 25mm thick unless otherwise stated. This isn’t really dictated by customer preference, but more by recent designs of PC cases.Īs for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. It strikes the perfect balance between cooling and silence with a maximum of 16.4db(A) and meets all the requirements to be a perfect choice for heat sinks, PC cases and radiators. The SilentWings 3 120mm PWM model combines all of the above best-in-class features. This results in very low vibration and silent operation with less energy consumption. The six poles of the motor produce a smoother transition between the magnetic poles. They feature a smooth-running 6-pole motor, an advanced fluid-dynamic bearing, a unique airflow-optimised fan blade design and a fan frame with funnel-shaped air inlets.
The third generation of this award-winning fan series offers unrivalled and uncompromising performance with a broad range of meticulous optimisations. Removable anti-vibration mountings minimise the transmission of vibrationsīe quiet! SilentWings fans stand for state-of-the-art technology, virtually inaudible operation and superior cooling.The rubberised fan frame producing extremely high air pressure.
Seven fan blades with optimised surface structures ensure excellent airflow.Advanced fluid-dynamic bearing (FDB) enables a long fan life.6-pole fan motor with three phases giving less vibration.Virtually inaudible operation at 16.4 dB(A) PWM fan.
