AC Infinity MULTIFAN S2, Quiet 120mm USB Blower Fan with Speed Control, for Receiver DVR Xbox Modem AV Cabinet Cooling

I recently picked up a 3D printer and decided to see if I could get my SG-3100 running a bit cooler. It's stuffed in a cabinet at the moment so I was originally just planning on adding some ventilation to the cabinet itself. But now that I have the option to print any custom design I decided to order a small USB powered blower fan and see if I could lower it's average temp down a bit more.

The design still isn't finalized since I'm still waiting on the fan to arrive, bit I figured I'd share to see if there was interest in something like this (I can upload the design if anyone else wants to try printing it as well).

I was also toying with the idea of raising the router up a bit and started on a small stand that would elevate it a bit, giving it a bit more breathing room. Here's what that looks like so far: https://imgur.com/nMvced6

Once I get a chance to print both of these to confirm the dimensions are accurate and fitment is good I can share the 3D models with anyone that's interested. I'd also be curious to know is anyone has seen either of these solutions accomplished a different way. I tried to do a bit of searching for parts like this but wasn't able to find anything other than one other simple stand on thingiverse.com.

I use AC Infinity system. They have a couple different styles of fans to use and thermal controller.

I went with these because I didn't want to put holes in the cabinet and more importantly I don't have enough room for the fan depth due to my equipment takes up almost all the width of the cabinet. I placed two on the top of my receiver and have them blow out the back of the cabinet.

I also bought the thermal controller so I could turn the fans on and off by a set temp.

IMO it's cutting it pretty close. For $15-$20 you can get an AC Infinity fan to put on top. Worth it for the piece of mind alone.

I use this one if anyone is looking after reading this. With this to automatically turn on and off.

They have the same drives inside (all of them are SMR). In addition to the USB ports mentioned, the Backup Plus also has a 2 year warranty compared to the Expansions 1 year. Yea they both get hot, all external drives get hot. They're sitting in a plastic box with no active airflow, of course they'll get hot. Get something like this for it if you ever want to run it hard:

https://www.amazon.com/AC-Infinity-MULTIFAN-Control-Receiver/dp/B012CL2V3I/ There's not enough ventilation area for a regular fan, so a loud blower is really the only effective solution. Just switch it off when temps reach normal levels.

They'll be fine powered on all the time in normal situations, the temperature only becomes worrisome if they're transferring at full speed for a prolonged amount of time. They stay under 45c otherwise, which is warm but acceptable.

Had a similar issue. This:

Is great since the squirrel cage exhausts the air at a right angle, pulling air from the top or side of the AVR and sending it out the back. Just one sitting next to the AVR is all I needed in a tight space.

Sure!

Just adding, my TV will be mounted and free-standing, so the console was really to hide components, consoles, power strips, networking, maybe a NAS.

Also considering buying AC Infinity fans on the cheap with temp sensor to kick in. They're affordable, quiet and will keep the whole console pretty cool even with a receiver or closed doors etc.

1 small fan was the difference between my receiver being too hot to touch during movies and ice cool. They even make ones that sit on top of the receiver horizontally and blow air out the back (this one).

I keep it on low all the time and you cant even hear it when everything is off, so i didn't bother with the temperature sensor. Cheaper to just replace the fan if it dies after a few years lol.

I had the same issue. A fan helped 100%. Specifically this fan:

My wineador had no fluctuation between top and bottom when the top and bottom rows are relatively clear. Since then i stacked it with boxes and its not perfect, but a WHOLE lot better than just the internal fan.

I also noticed that the amount of humidity leaving the fridge due to condensation has decreased, I think because this is blowing right across where it condenses, putting it back into the air.

The header is a small port where the connector at the end of the fan’s wires connects to. That’s what I unfortunately broke off.

It’s serendipitous you posted that link because as I was looking for something last night, I came upon a similar possible solution and it’s the same company and almost the same thing. Only instead of a fan, it’s a blower.

My thought was that I would just remove the fan from the Mac mini, put the cover back on, and then set this blower behind it to where the air discharge is blown straight into the vent at the rear of the Mac mini. Hopefully. I can even butt them together. What do you think?

I found some good fan solutions for media cabinets by AC Infinity on Amazon. Just got one of these for my receiver and I love it. It is currently unavailable due to one of their shipments having some issue with a noise, but I have no issue. Hopefully it will be back in stock soon so I can get another one. They've got some interesting products...link.

For V2 I am planning to test an air filtration system using large blowers and both kinds of filters you mention, in a setup similar to this. We'll see how it goes.

Do you have a lot of space above and around the amp? I have very little space above my Marantz receiver, and since it can get pretty toasty, I got two of these to put on top:

It turns out that I just needed one, and it keeps it cool to the touch all the time. I can faintly hear it when everything is completely silent, but it's not an issue otherwise.

They make them either top or side vented. They also make fancier fans with thermostat controls that will go over the top of the entire receiver, but I couldn't even fit that into my shelf.

Haha me too, I added a turbo to this case to exhaust air out of my motherboard chamber.

Looks ghetto but it works.
