Much more relatable than the mac repair videos for me. I was more than half expecting you to find out that the old fan wire colour coding didn't match the new fan wire colour coding.
It would have been fitting if I found out the industrial fan was something stupid like yellow is positive red is ground and black is tachometer... Glad it wasn't that messed up.
@@A2000MHz Yes, with so much of the stuff that is coming out of China these days, the color of the wire often means absolutely nothing. People should always verify the pin-out of the wires, and not just assume the color is correct. While with some things getting the wires backwards won't hurt anything, other things could be damaged by assuming the color of the wire means something.

Great to see you back with us Paul. Seems like a million years ago we were just some randoms on Rossmann live-chat. The proper solution for reducing your fan noise was to just disconnect them and ensure you keep the office/home airconditioner down to about 0'C - perfect :D Looking forward to seeing more from your channel.
But if i just disconnect the fans then I would have to build up a 555 timer to provide the tachometer signal to keep the fan fault light off. Might be a fun project...
Hi Paul, it is a pleasure to see that you are still making videos and on this occasion, you got FAN-SPIN but for rather better reasons. Nice to watch other content than MacBooks :D Cheers.
Great video, I have of of these as my home switch and man it is loud. Great product, but it dwalfs my fridge in volume. Best part is i searched for the fans Paul has used, and they are in stock at my local computer shop. Ill be playing along from home rewatching this repair next weekend! Thanks for this video Paul, it is fantastic. I am a big fan of recycling and keeping electronic equipment running, and channels like this allow novice repair folks like me to give it a go.
Great to see you! I actually unsubscribed Rossmann as I always liked it for its technical content and that is no more. Very glad to see this, I love electronics, fixing and exploring how things work and see people with great skills sharing their knowledge.
Good to see you back, always good content! I miss those late night streams of rocket league haha. Oh boy those fans sounded worse than a pair of high RPM Delta fans.
hihi and I have changed to turbo golf racing, I'm getting pretty good at it to, top 200 world rankings. We keep saying we should stream again. I might start streaming on my twitch channel again with it.
I don't live near EWR anymore and I can hear EWR over the screens. damn those fans are loud. Judging by broken button, dent marks near where button is (front panel, diagonally shaped), along with another dent near the fans, I feel like someone smashed this right into a wall or something and damaged the buttons and possibly fan bearings as well. two fan bearings kaputing at same time would be unlikely so I guess those fans were intentionally put in there to have maximum airflow into the POE switch.
I love that little "solder pen holder" attachment you have for the Flux syringe. I scoured Hakko site and other avenues for buying crap and found nuthn... figures.
That was 3d printed by a fan of my previous job. It works really well. I should get into printing and make some more. I really want one that holds the 30cc and a 10cc. The one I have now is for 2 30cc
That's way more up my alley than MacBooks since I'm an IT enthusiast and do IT for small businesses. I just cannot believe one thing: that those Noctuas have all the CFM and airflow needed to push enough air thru the box. The original ones are pretty much turbines for a reason: have you noticed a puny little radiator inside and no compartmentalization? So just wanted to ask: have you looked at the thermals under heavy load (like, lots of higher current PoE devices) and did you compare the datasheets for the fans? It's just I've had the same problem - a server rack of quiet equipment and just one loud PoE switch, and I decided not to modify it for stability and longevity...
Started out easy enough until the mosfets had to be removed. I might have looked to connect directly to the rails and leave the transistors, but the way you did it was very clean. Very professional repair. The only thing about the Noctua fans seems to be that they come in excessive packaging.
The box for those fans were extremely excessive! The fans were not very expensive but I wonder how much of my money bought the box, with its double velcro flaps full color information panels, soft touch antimicrobial like finish, print foil badge, and vacuum formed insert. We all know their name and know they make a good product. I still would have paid the 15$ a fan if they came in a white box with their name on it. Even better if it was 10$.
Happy new year Paul. All my D-Link (smart) switches break eventually, so not using that brand anymore. Granted, it where not enterprise devices. My TP-Link switches seem to still work after 4 years without issues.
I have a good mix of switches now but my very first switch in 1996 was a D-Link 10/100 switch. It still works, just useless for today. I like the Mikrotik I have in the rack so much I got another smaller one to run the stuff im my garage. I have some TP-Link stuff, I like them, especially the kasa smart home stuff.
The mosfet maybe there for variable fan speed (max speed only when the switch is too hot...). As there is a lot of different version for the NF-A4x20 (5V, 12V, PWM (4wires) or 3 wires) you could have explain your choice as many time for network equipment the fans are 5V models. Also you did not compare the Airflow/Static pressure or the original fan vs the noctua. Noctua is very good at making low noise fan but there's no magic: for effective cooling you need to move a lot of air and it makes a lot of noise... If you don't use the switch at max capacity it shouldn't be a problem but if you use the POE at max power you should monitor the temp via the admin. Just saying because every video on YT about reducing noise using these fans don't mention the Airflow/Static pressure. The manufacturer choose the fan specifications depending on the cooling need, not the noise they make... Of course they can use 4 quieter fans instead of 2 for the same airflow but it's not really the same price (the noctua fan is $15) It's just my 2 cents, just want to add some informations 😀
I know, I really do. But my fiancée is allergic. We are looking into getting a Russian blue, they are supposed to have much less of the stuff you are allergic to. I do have turtles, I can work them into some videos.
Glad to see you again Paul! Hoping to see more content on your channel
Paul S is #1
I'm so glad you are uploading more!
Hi Paul! Good luck with your new business! Nothing beats being your own boss

Thank you! As long as the customers can find me this is gonna be great!
Glad to see you back and best wishes for your new business.
Happy New Year Paul , and hoping that your business goes well which I am sure it will
Great video dude. The way you explained things, the editing, the presentation.
Can't wait to see more. 🤜🤛
Hi Paul,
As Pedro said, happy new year, best wishes to you, your family and your business.

Wonderful to see you posting stuff again . Best of luck in your new ventures. 🙂
I was hearing some fan noise and that yes I can hear some fans. And then when you plugged it in I was like "Oh..." lol
Happy New Year Paul.
great start paul wish you all the best for the future

Is there anyway to use a LM317T or something similar to control the stock fans as a cheap alternative for light load applications?
Best wishes in your new endeavor!
Thank you!

Nice work, not even Paul Daniels could do that.
don't fans spin the opposite way in Australia?

Ya know, your name here is what used to come up on the rossmann group phones when I called in from my cell.
The mosfet maybe there for variable fan speed (max speed only when the switch is too hot...).

It was a long time since I saw a milipaul of flux!
Paul!
Tim!
Might have a Wii for repair 👀
Paul queue is RANDOM
You need to correct the lack of cats in your videos if you want to be taken seriously in electronics repair.
I know, I really do. But my fiancée is allergic. We are looking into getting a Russian blue, they are supposed to have much less of the stuff you are allergic to.
I do have turtles, I can work them into some videos.
Paul is a turtle guy :)
Industrial equipment schemes way to impossible to find, that's true.
Hello. I need a help. Cnn you help me
Fan buy link pls

What?! A button replacement?! Oh F it! I'd rather drink a bottle of vodka and play civ. (the first one, from 1992.)
but the button replacement was the easy part, changing the fans... wtf...
@@A2000MHz OK, tomorrow, after 1st coffee, I'll watch what you did.
Hornet cafe
Noctua makes really much garbage.
No more cat poop scooping for the NYC defector? Nah just joking. No right to repair = more money with cat videos?
Only turtle poop scraping for me now.
