To exhaust the hot air, have you considered installing a Panasonic WhipserFit ventilation fan? The CFM is high, the noise is low, and they are used in bathrooms.
You can get a smoke pen to see how the airflow is or a thermal camera to see if things could be improved on the cheap. I don;t know why I just thought of this now instead of when we talked about it last year.
@@jfkastner A smoke pen though typically gives off a really consistent thick smoke but I get that it's cheaper and might work as well with their method as well.
This is what he needs to do, because adding that big exhaust cfm would cause most of the air to just come in and go up and over the rack, and measuring temp at from of rack has no point, its just measuring intake air as it flows in front of the head sources than than the exhaust temp of said head sources. its like measuring the temp of the outside of your car thinking that its going to be cool inside but you have the heater on inside
Just wondering if you ever looked at a bathroom type exhaust fan that was high CFM that could pull hot air out of the house vs just moving into another room? The cost could be very comp to buying multi units of the fan you are buying, but not just move the hot air to another space within the house, in turn making your AC unit work harder. You would need a vent in the door still to pull cool air in from the house, but it would push the HOT air at the top outside. You may have already looked at this.
I wonder if adding some AC Infinity 120s to the top of the rack would help reduce the heat trapped inside the racks? Only other thing would be to add a small floor fan at the bottom of the closet and point it upward to mix the hot and cold air.
I am playing with the idea of doing that! Not sure if I’ll commit or not. I feel like it would help. I have a feeling in the summer I’ll end up doing that
Looks like a decent solution. I reckon if you need more the next step should be to just increase the size of the intake vent. Rather than trying to push more air in, just make it easier for the existing fans to draw air through - they're probably limited by the total area of the gap under the door plus the intake vent.
The servers have always been pretty chill in the past like 50~55C or there abouts. It’s the network stuff that gets super hot. Like 75C or more. The new switch doesn’t show the temperature
@@SPXLabs I like your idea, its good. IMO at my house i was going to run a bathroom fan in the closet, pull air out of the closet and have it plummed into the bathroom vent in the other room beside me.
@@PunmasterSTP No, I've never thought about that kind of stuff long and hard. I'm also not witty like that. But I'll attempt to humor you. Any good Linux puns?
There are a lot of issues here that are causing bad airflow. without making this a comment about this and that is wrong, lets start by understanding current issues and what airflow is needed: Reality - seams that you are trying to cool a room that houses heat generators rather than cool the generators (rack equipment) Simple first issues I see 1: your rack gear is too far back 2: having a lot of exhaust power and a clear route from your door the up and out the exhaust will bypass your rack gear. What is needed 1: Your rack gear pulls air in from the front and sends it out the back, so direct air through your rack gear 2: find a way to exhaust from back of rack - in your case, put a block mid rack and up 3: measure the temp at the back of the rack not the front, you already know the air in front is the same as what comes in In my home rack, the exhaust of all my rack gear feels mildly warm and some gear just cool. At my office the server closet has all a/c coming in from front down low, and all exhaust from back of rack line and no airflow is allow to go over the racks.
Wow! Thank you for the detailed post and suggestions and your experience. For almost a year now I have kept my servers angled towards the bottom vent so they help pull air into the room and that does help. If things become problematic in the future I’ll come back to this post and use it for future designs. Thank you
@@SPXLabs honesly, the first think I would try, measure temp at back of server rack, then place a big piece of cardboard from top of rack all the way up seperating room into two halfs, not air tight or anything, just a good mockup, dont worry about big leaks, just try to divert most of the air through rack instead of up and over
Are there any forums or such for modding rackmount cases? Finding a 3U ATX hot-swap with ATX psu is hard to come by with limited options. I've spent several hours searching Reddit, Google without luck. Discords?
Really confused. Why do you think 80°F is a problem that needs a solution? My server closet goes up to 97°F in the summer and my internal system temperatures are still acceptable. Hard drives are a little warm at 107-113°F max, but that's about it. The operating temperature ranges of IT equipment often go up to 40°C (104°F).
Temperatures around 90 make me uncomfortable. Just worried about early death of hardware due to prolonged excessive heat. I know 80 is fine but upper 90s just makes me nervous.

Nope, never heard of it. :/ too late now of course
Also if you get a smoke pen I would put a camera inside so you can close teh door to see how the smoke moves with the door closed.

My neighbors always use burnt herbal plant matter to test airflow, indoors & outdoors ... they seem happy with the results

You ain't gonna hear me complain about you hosing Celsius. It was a balmy -6°C not too long ago. Very warm for this time of year.
That handywork got bytemybits quality written all over it. 😋
That’s where I learned it from!

Yeah, in the previous videos we talked about all sorts of alternatives

This is the single biggest issue in that setup is that he is not pushing cool air through the servers, but around it
I like Celsius! As for your cut job on the door.. a jigsaw may have worked better?
Works great for electronics
I'm ok with you using celsius!
Glad one of you is
The hell! Celcius is king
🤭

I think, if I continue adding too much more, I will either move things to the garage or install a rackmount ac unit
@@SPXLabs Yep, fair call! (hehe you could move the laundry into the garage instead and take over another rooom....) 😆
That’s…. Actually a really good idea 😈
I wonder what the wife would aay
69 degrees. Perfect temps to run the PNAS at.
Exactly bro
What about using ipmitool to poll CPU temps?
The servers have always been pretty chill in the past like 50~55C or there abouts. It’s the network stuff that gets super hot. Like 75C or more. The new switch doesn’t show the temperature
@@SPXLabs Time for a Noctua upgrade and voiding warranties OR ghetto bolt on fans externally over the vents to force more airflow inside the switch?
@@ShinyTechThings @SPXLabs do it!!!!!!!
I personally would have just cut 1-2" off the bottom of the door, cold air in under the door..
Like originally, instead of cutting a hole for vents?
@@SPXLabs Yep.
Oh yeah. Maybe. Idk. This is fine
@@SPXLabs I like your idea, its good. IMO at my house i was going to run a bathroom fan in the closet, pull air out of the closet and have it plummed into the bathroom vent in the other room beside me.
Well done! At some point I would test the sensors, they could be off by 1 or 2 degrees
One day. Maybe I’ll use gasoline too cool a radiator
Holy shit, you can walk straight under the door into the rooms with these massive gabs between door and floor.
That’s what happens when you short 😭
@@SPXLabs 😂
69 degrees. Nice.
The best video ever!
Try two girls one cup. It’s a classic but you won’t find it in UA-cam.
This whole video was pretty...cool 😎
This guy, so punny!
@@SPXLabs That's why I'm here! Btw, if you ever want to hear a pun on a particular topic, just leave or reply to a comment and I'll get back to you 😃
I'd prefer to be surprised by one. I think it's more fun that way.
@@SPXLabsI can respect that sentiment. Out of curiosity, was there ever any topic you thought it might be hard or impossible to make a pun out of?
@@PunmasterSTP No, I've never thought about that kind of stuff long and hard. I'm also not witty like that. But I'll attempt to humor you. Any good Linux puns?
Could you not add a hot air return and AC vent from your current central AC system?
Thats the setup I have and it works perfectly.
This is the way...
That’s what I wanted to do originally. Long story short is no. Previous videos will say why.
I am know cisco equipment and you don’t get alarms until temperature reaches 105 degrees so 80 degrees doesn’t seem too bad
Yes but this was while it was winter. Imagine the summers!
Can you tell us about the noise level of the fan?
Yes.

What if you used a disassembled leaf blower on low?
Electric or gas?

Yeah idk man. If Google isn't helping you find stuff the only option is to post on Reddit and hope that someone see's your post. Sorry :/
I don't like it when you use °F 😢. I also couldn't spell it and I'm not bothered😅
add income air and exhaust to the outside :D
One day I will either add AC or water cool with the radiators being outside
wouldn't it work better if it were PULLING the air into the other room instead of trying to push it into your walls/attic?
I am doing that. Except instead of into the wall or attic, the air is being moved into an adjacent room.
Celsius is the way to go
LOL this guy.
why black? Aren't all your other vents white?
The white doesn't look as good to me or the wife. Yes they are white.
why not use a jigsaw?
Don’t have one and too cheap to buy one
First
"Five point two thousand" immediate dislike
Okay boomer. 🤷♂️
The awkward moment you understand "mini-split" is an air-condition unit and it starts from 300 dollars with a 50 dollar installation 😅😅😅
Man I wish it was a $50 installation.
