Review on 🌀 Ultra Silent Router Cooling Fan with Speed Regulation, USB 5V, Ideal for ROG GT-AC2900: Dustproof, Efficient Temperature Reduction by Leah Gomez

Received this as a cart filler and it does exactly what it says on the tin, 95% of users will never need it This type of cooling because these router chips run up to 120°C. My ac88u went from about 80c to 59-63c with a silent fan, ax88u 50-54c, but it can get very noisy and approach the max, but it will never be needed. as it causes more dust. Every week or two you will need to brush over the top. I guess I play around with it and turn on the fan when I get bored.
