SUNON HA40201V4-0000C-C99 40mm Case cooler
  • 40mm
  • 4700 RPM 5.5 CFM
  • 12.8 dBA

4 out of 5 eggs Such a nice little fan... 02/04/2014

This review is from: SUNON HA40201V4-0000C-C99 40mm Case cooler

Pros:

Another Cisco Catalyst 2950 install. As mentioned in another thread YOU MUST SWAP RED AND BLACK! The fan puts out -12VDC and fans run on positive voltage. Very, VERY quiet.

Cons:

Although it flows a decent 5.5 CFM, it is only at 0.08inH2O. The stock fan was 8.5 CFM at 0.303inH2O. As long as the sides of the switch stay open it shouldn't be an issue.

Other Thoughts:

When comparing fans of the same size you can have quite OR you can have high flow. In my case I probably could have done without a fan, but I wanted to put one in as a "just in case".

REMEMBER: SWAP RED AND BLACK LEADS IF INSTALLING IN A CISCO 2950 SWITCH! If you don't you risk letting the smoke out. Electronics run on smoke, and if you let it out they stop :)
