Safe temperature for 24 port SD-Switch

Hi everyone,

I swapped out the included fans on the 24 port SD-Switch as the ones it came with were extremely loud with a loud whine to them, so changed them for Noctua ones and now it’s virtually silent. Unfortunately I forgot to check and see what the average temps were before swapping them and would rather not have to go back and put the old ones in just to see. Just wondering what the safe or normal range should be for the SD-Switch so that I can ensure the new fans are working properly. It’s running around 101F right now, and the Balance 305 we have is showing 131F which has the stock fans in it. Thanks!

I’m just about to get a unit. Which model of Noctua fan did you use?

Noctua NF-A4x20 PWM, Premium Quiet Fan, 4-Pin (40x20mm, Brown)

I never got any response regarding safe operating temperatures but I’ve been running it with three of these since posting and I’ve had no issues. The difference in sound is insane. It goes from jet engine to basically idle desktop PC.


Thanks @liammonroe fans ordered, i’ll get them in asap… I’ll share the results, but i’m sure they’ll be as yours.

Peplink, please use quiet fans in new produced switches and routers. I just ordered a 24-port Rugged to replace my roaring AC switch. Many small business companies do not install the devices in seperate noice cancelling rooms. Increase the price but not the sound :wink:
