*** FAQ and Updates! *** - First of all, to all the people that are concerned about my marriage: this was a joke. My wife is incredibly supportive, but I also try to find ways to go about projects that are less bothersome for her. She's amazing and had to try very hard to even seem angry. - I've had a lot of people suggesting that I should vent into the attic. I was a bit hesitant on directly venting into the attic, and maybe that isn't something to be hesitant about. At the same time, I already have an HVAC company coming out to look at adding a return duct in that hallway. I'm considering the possibility of putting it in the closet (once I consult with them on it). I'll post an update here as to what we decide on. - I'm printing grills for the bottom fans and have plans to lock this closet once our kid is able to open doors.

From what I saw in the video I think the louvers on that door are too narrow for you to do a full return using just the closet. I'd maybe recommend doing the hallway one as planned but adding a second 6" return duct for just the closet. If they're already out doing the work and it's all in roughly the same area it shouldn't add too much to your bill. Or put the old door back on and cut a large opening in the bottom.

Don't vent into the attic. That's a big building science no-no. You want to keep your living space separated from your attic space and you'll cause major issues by actively bringing humid air into the attic, plus killing your energy bills as you are now throwing away conditioned air into the outdoors.

I used a louver door for my lab closet as well although I just used 2 cheap white box fans I mounted to the door with some simple screws, lower in and upper out. I managed to bring it down from around 100f all the way to 3-5f of where I keep my house at (70f house, and 74ish Lab) on the lowest fan setting. The fans were $21 each at Home Depot and the door was around 155 after cash back deals from my credit card keeping the whole project right around $200. Pretty happy with how it turned out and funny that you put this out as I did this only a few weeks ago with it starting to warm up. Cool little project and nice video, it should keep our hardware happier longer.

Nitpick suggestion: 9:40 - Most 2-post rack mount equipment has _all_ the weight behind the plate. This makes it pivot on the top of the mount, swinging the bottom out. If you only have 2 screws, you will almost always get a more secure mount putting them both on the bottom instead of diagonally.

Re: Home Assistant, you could at a minimum put a camera on the controller so you can see what's going on there, and smart plug to switch the whole thing off or on (not sure why you'd need that). Another route if you didn't mind all on or all off is some sort of temp sense connected to home assistant then a smart relay that turns on and off when the temp goes up and down. It would be simple to even do a high medium low setup with relays in series. Sometimes we go straight to the nerdiest solution when there is something less complex that will get us there!

My experience as a youth doing maintenance in a building server as housing for college students was priceless. I already knew spackling, sanding and painting, but hanging doors that were level and flush, and chiseling for hinges and striker plates was invaluable. Really came in handy when re-hanging a 200 lb. entrance door in the building where I live that was being pulled off the frame by its own weight. It opens and closes like a dream, but my neighbors still slam the door...

Arctic fans are good for this use case - they make TC variants of most of their fans that integrate the temperature control logic into the fan. There's a thermistor on a bit of wire attached to the fan, so you just supply 12V and the fan figures out the correct speed. Just add a 3d printed louvre if you're going down the "cut a hole in the door" route and you're set

closing all of the wood slats other than where the fans are (from the inside so its hidden) would promote better airflow, as well as having one set of fans for intake and one for exhaust. but also having a return for the hvac would be nice too. then you wouldnt have to do anything to the door/fans just make them all intakes (or remove them entirely)

I have a workshop in my garden with a (now mostly empty) 36U cabinet. 15 years ago it was kept warm in Winter by a pair of Compaq Proliant Dual Xeon servers, these are essentially space heaters that have a side hustle in data storage and handling. Great in the Winter for free heat, a nightmare in the Summer to keep cool. Electricity must've been cheap because dual 750W PSUs aren't that efficient! Today I run my web/mail server on an old Intel Atom 330 system @ 30W.

I wouldve used MDF/Plywood to replace the door cut out some fan holes then covered the entire thing in a nice fabric from the outside. But this does look very integrated to the rest of the house. Also would prefer celcius for the temps, but another great video from my fav tech channel.

One option to consider for a future upgrade is take some aluminum trim pieces from the hardware store(I think they come in like 3 foot lengths) and use those to mount some 200mm fans will move more air and be quieter.

Looks good. I'm glad I have a heated and dehumidified basement for gear. If that where my closet, I'd be tempted to cut the door an inch off the floor, then adjust (sand) the louvers at the top to allow for exhaust, probably just mounting large fans straight on the door. Those new 200mm computer fans would be slick.

For fan PWM control I'm using tasmota on an esp 8266. By default HA thinks it's a dimmable light but that's easy to change. For me this means I can control the fan speed based on the temperature in my server cabinet. As the cabinet is in my home office I can even alter the max fan speed depending on room occupancy so it speeds up if I'm not there to hear it.

This was a great idea. We have a large home and most of the bedrooms do not have an integrated air return for the air conditioning ducts. So I am actively trying to come up with a solution to vent the hot air into the corridor with the central air return. So thanks for the idea.

@HardwareHaven

Ай бұрын

Yeah I'm actually in contact with an HVAC technician about adding a return either in the hallway or possibly even inside that closet lol. We have no return on this side of the house and its very noticeable.

Yep... Once the wife is happy the temperature at home should be cool 😉. Lol

I love that your wife looks exactly that fits for you! love it!

You can use a rotary fan, such as you can find in conditioner. It's cheap, silent and power efficient.

I've been experimenting with cooling my homelab in a similar way, but my wife allowed me to cut two giant holes in my door (she didn't care was her response) i have two square grilles (don't remember the name of them) one at the top and one at the bottom, as hot air rises, I have a 12v fan mounted blowing air out of the top and one sucking air in at the bottom. but I wanted to try something like this, already added one of those pwm fan controllers to my amazon basket, just need to design something to 3D print and get more fans, currently the temp inside is about 31 degrees Celsius. Also, I use the same room to store my 3D filament as its got my boiler in and my homelab so the humidity is very low, normally its around 50% in my flat but in the cupboard its been as low as 20% great for drying filament out! Love your videos keep up the great work!

You should also look into improving your overall home ventilation since your aranet (which I'm glad to see you have) is showing some high CO2 levels at 1200 ppm and you want to keep those below 800. That might be the next home upgrade you do for your families health to add in an ERV system into your house and you could make a video on integrating it into home assistant with additional CO2 sensors for demand control ventilation.

this was awesome I have the same problem. my fuse box room ( I cal it server room with breakers ) is hot its around 24c so im taking some kind of the same ideas you got thanks ! can't wait on the nas videos. I recently go a Micro server gen 10 for cheap at 125 euro, ( the firmware of the Broadcom controller got updated so it can do HBA) put 12tb HGST rectified drives in it as a backup server. and called it a day!

You can set up an SNMP server and monitor all your devices there and have accurate readings for each one. PS. I have a closed rack and I found that putting a fan directly above the equipment it cools the hole rack of 3 network eq and 2 RPIs.

If you want to cool down the top you could add some sort of cooling piping to cool down the hot air at the top and have that air sent back down

I need to setup a thingiverse or something, but yeah this would be specific to that exact door sadly

This is a super interesting video. My network closet in the office/bedroom 3. This makes the office very warm. I thought about installing an exhaust fan similar to what you see in a bathroom right above my network rack. Also my wife uses a 1500 watt space heater in the bathroom. The network closet is on the same wall as the bathroom. I was thinking I could duct over to the bathroom. And push that hot air down in front of the shower curtain. That way when you open the shower curtain you don't get that gust of cold air. I just have to convince my wife to let me cut a hole in the ceiling... Well two holes in the ceiling.

Love your closet setup!

Great stuff! Keep it up!

Very cool idea! Maybe you can dampen the sound by adding sound dampening material (thick felt) where there are no fans, and possibly lining the ducts. I would probaly also try to duct the hottest machine(s) directly to the door, for even better temps and acoustics.

It feels like the bottom intake is more important than the exhaust on the top. I'd suggest to try going with intake-only for a few days, maybe you can do without the upper part altogether and save a bit on noise and power to run fans. Or as others said make an attic exhaust instead, where it will truly make a difference.

easy way to intergrate it into homeassistant would be use a smart plug, and a seperate thermostat which reports it back, can cut the power to the fans maybe even monitor power draw from higher RPM's

Painter's Tape is a better plan. I suggest another row of fans blowing the other direction and adding dust filters.

Lol. Loved the wife aggro mentions! The struggle is real.

Maybe you should have the bottom fans pointing down or horizontally to enhance natural airflow

It’s looks very nice 👌

You said that you didn't notice a big drop adding the intake fans. I wonder if that isn't an airflow pattern issue as you have the intake fans on the bottom (in other words, could the cooler air be getting exhasted?). Maybe try printing a divider to deflect the input?

I wonder if it'd be more effective to use two big-ass fans, like a 280mm or larger. One at the very bottom to draw cold air in and shoot it towards the rack, and one at the top to blow it out. Maybe even add some dust filters to prevent anything from clogging it up?

Using a microcontroller you can spin this up and down based on CPU temps instead of room temps if that would be preferred.

I went with Bambu Lab because one of their big "selling points" is that they automatically handle bed leveling, calibration, etc. I've basically done no maintenance other than lubricating the rails which there's a video walkthrough on when you set it up. Other than that, it's mostly just getting filament and finding or creating models.

The new door is an excellent idea. I do want to ask, was venting to the attic not an option?

Same thing I said. Just keep stuff on a rack/shelf.

Any thoughts on plywood flat mounting instead of rack mounting?

On that slat door I would have put a sheet of mdf/wood on the top half and mount the fans on that so air could not get in thru the slats so close to fans. I think it will give better circulation but the downside is no 3d printer usage.

What is above the closet? Second story or attic? If attic, I would have thought about venting through the ceiling. See the temperature difference with just the louvered doors and natural updraft. Then intake fans at the bottom of the louvers. Then an exhaust fan in the attic.

Any chance to get the STL for those vent adapters? My "IT" closet has a similar door and I could use a little airflow.

you might want to try a blower fan instead of axial fan for better air pressure through those slots. Best solution is still one of thsoe AV closet fans above the door exhausting

New window units or portable units that utilize inverter or dual inverter tech are a lot more efficient compared to older units. I purchased 3 units for my home they draw so much less power it shocks me how much it cost for the summer months.

Those air ducts are pretty sweet, really making we want a 3D printer lol

Happy Wife = Happy Life Colten, My buddy you may have cracked the code to live life

What if you put intake fan up and exhaust fan down. As cold air is heavy it will naturally fall down over your system? I would like to know if that makes any chances in temperature in there and your thoughts on this 🤔 Really like your videos, working on my own nas after watching your videos.

I saw on reddit somewhere similar solution but that guy cut 10 mm of bottom part of the doors and 20 on the top. Made similar funnel air duct to move air under and on top of the doors :) that can be even better solution becouse you suck coldest air and exhaust the warmest air :)

FYI - expelling hot air always exceeds pumping cooler air in.

Thought most Americans have HVAC, why not just connect it to that? The slats slow the airflow so much, just cut a hole the same size as the fans.

Have you considered placing thin foam spacers between the fans and the ducts?

Do you have any videos on running windows on a remote or seperate computer (maybe even one without a hardrive) through a docker or something like that?

Look at using Gaffers tape instead of Duct tape. Comes in white which should blend in much more cleanly.
