Great to see someone actually call a spade a spade with the USG. It gets hot, so it's a good idea to cool it. I'm using a dust filter over the intake of the fan as active cooling will speed up dust infiltration. I'd also use a clamp or two instead around a drill press. A kid in my shop class almost lost a thumb using a similar technique shown.

Of course you can filter the fan intake. I typically install the USG inside a rack that is already supplied will filtered air.

Placing the USG vertical helps allot due to better passive cooling

I've done similar action with my USG. Maybe will be usefull for you my findings: - Ive used external fan from intel, but still it was too laud. Therefore I decided to add two resistor in line (2 in order to have gears). connected the fan to rack itself + radiator on top. Fan blowing on the way to USG. But there is one important risk (also in your case). Air flow causes electrostatics - USG HAVE TO be connected to ground. I've destructed in such way (circut) the first one...

nice video!

This is a great video and I’m going to do just this for my USG. Surprising how hot they get. One thing I may change is to have the fan pull the air through the unit, instead of pushing it through. I think this is typically how small equipment with fans is designed. Any thoughts you have about air flow direction appreciated. I’m sure it will cool off the unit either way.

Hi David, sorry I didn't see your comment until now. As far as air flow direction, I think the fan blowing towards the PCB is the way to go. And here's why: the directivity of the stream of air is the difference. Imagine the flow of air hitting the PCB and then flowing over and outward across thew PCB towards the chassis sides, taking a little heat (directly from the shell of the ICs and other components) away with it. Now, if you flip the direction of flow, you lose the benefit of directivity. The air source will be originating from any and all points inside the USG. Furthermore, the rising heated air around the PCB components is the only heat you'll be able to remove. The little 40mm fan isn't like a vacuum on its inlet side, it's not very directional. So, I'd stick with an active, direct stream of air on the PCB. Thanks for watching!

I disagree, only in that negative pressure will promote the ingress of dust through any gap in the unit. Though this is really only a consideration if you were initially going to use a dust filter on the intake side.

Will this also work for the gateway max USG?

Hi, sorry I missed your comment. For some reason I didn't get a notification. It doesn't look like the gateway Max has that same top panel. So you won't be able to use this fan mount. I would definitely put some thick feet underneath the gateway Max, similar to how I did it in my video. And then put a fan near it, and in a manner such that the air flow will envelop the entire device, top and bottom. The gateway Max looks like it has solid plastic panels all the way around, top and bottom, so modify at your own risk! Thank you so much for watching and commenting.

Video is well put together dude. Good job and nice 3d modeling. If you think there is demand I could plasma cut some of those or i've got a guy who can laser cut.

You saved the stupid Ubiquiti

Well.. tbh its kinda strange to make a 10 minutes video for "fan installation" and its actually just a long tour on cutting a big hole.. never use the part .. and put a something else on it .. the end result kinda looks ugly (my opinion)..
