Review on 7CM Adjustable Speed Ultra Silent Router Cooling Fan for RT-AX86U - Dustproof with Temperature Reduction by Robert Dabney

If you have an RT-AX86U and it is in a place without good ventilation or AC power like mine, I definitely recommend buying this product. Thanks to the ventilation at the back of the RT-AX86U, these fans face towards the Wi-Fi chips, since the area where the CPU is located is behind the solid area where the serial number label is located. However, along with the Wi-Fi chips, the CPU gets cooler. I understand there's some debate about CPUs being able to handle a lot of heat, but the difference of over 40 degrees Fahrenheit is huge and will likely go a long way in extending lifespan. Almost $300 after-tax device, especially since most of us use the router non-stop until it dies or we update it. If dust is a problem, find a dust filter with adhesive and place it in front of the fan in the router). My area has been over 80 degrees Fahrenheit for the past few weeks, and the room where the router is located is at its hottest around 6pm. Below are examples of CPU temperatures at the time, guess when I installed the fans ;) 60 - 1397/14/2021 - 65 - 1487/15/2021 - 64 - 148
