I have about 5 switches which are noisy. I actually removed the fans from some and let the rack fans do the job by aiming them right across the case.

So it’s just noisy because of old fan bearings worn ? I.e new fans would be much quieter ??

Yes, the fans are I think like 40mm, they are small, spin pretty fast and just wear out. Chances are it sat in a data-rack in an office for the last 10 years. I know I'd feel kinna rough if I was made to work flat out for 10 years! You can get them for a few pounds. Edited February 7, 2020 by Carrerahill 1
joth Posted February 7, 2020 Posted February 7, 2020 I got some of these to quieten down my ubiquiti switch & router https://www.amazon.co.uk/dp/B071J8CZP9/ Be sure to get the deepest ones that fit (e.g. 40x20mm not x10mm for the above size) as they'll move more air per rev hence can be run slower The switch likely won't have speed control either but you can get little PWM controllers to put in line with them to set at a low speed. Iirc PoE switches can run a fair bit warmer so check again after everything is hooked up. 1

Probably the biggest energy saving device available.
Jeremy Harris Posted February 7, 2020 Posted February 7, 2020 I deliberately hunted around and found both a 16 port switch and a router than don't have fans. I've two PCs here that don't have fans either. I even get annoyed by the fan in my laptop, and its replacement is going to be a fanless model.

Pocster Posted February 7, 2020 Author Posted February 7, 2020 I used a tool less keystone for the 1st time - did cuss a bit . I think it should be faster than crimping .....
Pocster Posted February 13, 2020 Author Posted February 13, 2020 Almost half the cat5 cable in . Pretty colours help ! 1
ProDave Posted February 13, 2020 Posted February 13, 2020 Okay I will bite. Why the termination strip and patch leads? I would have just crimped an RJ45 onto the end of each cable and plugged them straight into the switch. That's all I have done with the few I have in use.

Some cables are crimped as stranded cat5 ; some or keystones as solid core cable . I prefer the patch board as it means the cables won’t hopefully get moved - so any unplugging etc . Done by patch cables ( pre bought ! Didn’t fancy making them )

I like the patch panels as they tidy all the cables away. I have mine flush with the plasterboard. You can adapt to phone and poe where needed. 1

This cupboard does not need SWMBO approval !! ???

Ideally the solid cores then will never have to be touched or moved again and can last decades. Analogous to why in a lighting circuit you have a ceiling rose rather than drop T&E to the pendant, say 1
