Description
The be quiet! Silent Wings Pro 4 120mm PWM is a high performance cooling fan designed for demanding desktop PC builds. It combines powerful airflow with advanced noise reduction technology, making it suitable for use as a case fan or for cooling radiators and CPU heatsinks.
The fan can reach speeds of up to 3000 RPM and delivers airflow of up to 83.9 CFM with static pressure of up to 5.31 mmH2O. A convenient three position speed switch allows you to select medium speed, high speed or ultra high speed depending on the cooling requirements of your system.
Its 6 pole motor uses a three phase design to reduce vibration and power consumption, while the Fluid Dynamic Bearing provides smooth operation and a rated lifespan of up to 300000 hours. The reduced clearance between the fan blades and frame helps maximise air pressure for demanding cooling applications.
Three different mounting options are included, allowing the fan to be installed in a PC case, radiator or heatsink. The 4 pin PWM connection enables automatic fan speed control through a compatible motherboard or fan controller.
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.
