Description
The be quiet! Silent Wings 4 140mm PWM High Speed is a premium PC cooling fan designed for high performance gaming computers workstations and enthusiast PC builds. It combines strong airflow and high static pressure with the quiet operation that be quiet! fans are known for making it suitable for demanding cooling applications.
The 140mm fan features specially optimised fan blades and a reduced blade to frame clearance to generate high air pressure. This makes it suitable for use as a case fan as well as on compatible radiators and heatsinks where efficient airflow and strong cooling performance are important.
A 6 pole fan motor with three phase technology provides smooth operation with reduced vibration and low power consumption. The fluid dynamic bearing further contributes to smooth and reliable operation while offering a rated lifespan of up to 300,000 hours.
The Silent Wings 4 High Speed model can reach a maximum noise level of 29.3 dB(A), allowing it to deliver high cooling performance without excessive operating noise. The fan also uses a 4 pin PWM connection, allowing compatible motherboards and fan controllers to automatically adjust the fan speed according to system temperatures.
Two mounting solutions are included, giving you flexibility when installing the fan. The pre-installed anti-vibration mounting helps minimise vibration when used as a case fan, while the alternative plastic mounting solution is suitable for radiators and heatsinks. The all-black design also provides a clean appearance for modern gaming and performance PC builds.
I was nervous about ordering a phone from here as I hadn't heard of them before, but it was a fantastic price so took the risk, and completely worth it. Phone is fantastic, brand new in sealed box, and arrived fast after ordering.
Great value headphones, haven't set them up yet, they are a present for my mum. However the transaction was easy, the website easy to navigate and a fast delivery. Grateful thanks
I bought a Fitbit which was cheaper than Argos. It arrived on time by Royal Mail and is working fine.
I hadn’t used this company before but I did check their reviews. I would use them again.
Website was easy to use I had some questions which were answered quickly and efficiently. I can't comment on the product as it's a Xmas gift for somebody
Item exactly as described. Posted quickly and well packaged. Great communication. I was sceptical as the price was so good but took a chance. Delighted with my purchases of Kodak blindbox key chain.
1st time purchase from A1 so was a little apprehensive having fallen foul of a spoof website recently. No need to worry though, purchased a Samsung S25fe for the best price in could find on the web at that time. Good communication via emails and delivery within a couple of days. All good.
