Homelab – Mikrotik CCR1009-8G-1S-1S+ Noctua Fan Replacement

I bought a Mikrotik CCR1009-8G-1S-1S+ several years ago and use as my main router at home. It was relatively quiet with lower load when put on a shelf, but after I move to the new apartment and put it into a network cabinet, the noise was much higher especially in hot summer. So I decided to replace the factory fan with something quilter.
