My latest switch, the Cisco SG300-52, isn’t all that loud in the grand scheme of things. In fact, you can read about my experience with the switch, including noise meters, here.
However, I like to keep my home office as quiet as possible because it shares space with my lab. This post will cover the steps necessary to replace the stock pair of Delta AFB0412LB fans with Scythe Mini Kaze Ultra silent fans (SY124020L).
Here’s a great DIY from Chris about reducing the noise level in your lab.
