I replace only the fans, in the future I will replace the whole system with this bran which even offers refill conector to the coolers. LED light are not so bright or cool but who care I preffer solid build quality instead. This double the weight of my olds ones. I think that is related to the better quality. It has a ARGB box which leave you to conect more light from your pc, I'd like if that was extended to the fans because it does not have daisy chain to conect one to the next one and the last one to the mother board. You will need to conect each one direct to your mother board and maybe need an aditional extension cable. This is a good product. Review: Fantastic PC Fans! - These fans are awesome!! I had a faulty board, so I haven't had the opportunity to use the PC extensively yet. However, the installation was straightforward, the RGB controller was easy to mount (using 2-sided sticky tape on the HDD side of the case), and the fans are of excellent quality. Upon initial power, they ran perfectly and were very quiet. I previously had a lower quality pre-built, and those fans were 2-3 times louder than these. The RGB lights are fantastic, not too bright or crazy, just a reasonable amount. I highly recommend this set! ## Features - ARGB lighting on front and rear - Multiple colors and modes for an individual look thanks to 20 LEDs - Nine silence-optimized fan blades for high pressure and low noise-generating turbulences - Remarkable performance-to-noise ratio with 31dB(A) at 2,200rpm - Long life rifle-bearing gives an operating lifetime of 60,000 hours ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KMF9H1Z | | Air Flow Capacity | 71.7 Cubic Feet Per Minute | | Best Sellers Rank | #69 in Computer Case Fans | | Brand Name | be quiet! | | Compatible Devices | Desktop | | Cooling Method | Fan | | Customer Reviews | 4.6 4.6 out of 5 stars (500) | | Global Trade Identification Number | 04260052188798 | | Included Components | Fan | | Item Dimensions L x W x H | 5.51"L x 5.51"W x 0.98"H | | Item Weight | 100 Grams | | Manufacturer | be quiet! | | Material Type | Copper | | Maximum Rotational Speed | 2200 RPM | | Noise Level | 31 Decibels | | Power Connector Type | 4-Pin | | Unit Count | 1.0 Count | | Voltage | 12 Volts | | Warranty Description | 1 year | | Wattage | 4.7 watts | ## Product Details - **Brand:** be quiet! - **Compatible Devices:** Desktop - **Cooling Method:** Fan - **Material:** Copper - **Maximum Rotational Speed:** 2200 RPM - **Noise Level:** 31 Decibels - **Power Connector Type:** 4-Pin - **Product Dimensions:** 5.51"L x 5.51"W x 0.98"H - **Voltage:** 12 Volts - **Wattage:** 4.7 watts ## Images ![be quiet!
