The discomfort around intake fans on carpet is hilarious. You're right, the carpet would, if anything, act as a filter for dust with most of it getting stuck on the carpet ready to be vacuumed. Do people think dust is magically created within the carpet itself?!
@klaernie Жыл бұрын
technically, the dust mites, that actually create some part of the mixture we call "dust", have more space to live on in carpet, since the surface area is greater. So one might argue that carpet is a better breeding ground for dust. But honestly I think most people on the internet confuse "PC getting dusty" with "air intake starved of air" - since PC feet usually sink into carpet, and if your carpet is a high pile carpet the carpet might block the intake. So just a regular case of people getting mad on the internet, having understood only half of it ;)

AC Infinity is very handy, I've used them for quite some time now and I have a 2U (4 fan) temperature controlled unit. Looks similar to what you have in the controller, but just 2U and with 2 sets of 2 fans to the side of the one you've got. The option you've got works very well if you have your fans installed in the rack. I may switch out the fans they came with for some Noctua ones. It is a great option, bit pricy, and their power bricks are particularly cr*p - I've had to replace multiple of them over time. The thing I like about the more recent models, is that they have the ability to turn off the display, plus the quality of the metal is good.

I've been a fire alarm engineer for 20 years so I've a fair idea about how much of a difference a 9dB drop in sound pressures can be and it really is massive. One way to maybe demonstrate it is that 65dB is considered the minimum for a fire alarm sounder. However, in areas of high background noise, the fire alarm needs to sound at a minimum of 5dB above the background noise. Ie, a 5dB increase above other noises is considered sufficient to make that noise distinguishable from every other noise in the background. Another way of putting it is that you'll generally lose about 5dB going through a standard hollow door, or 10 dB going through a 60 minute fire door.

It's not got a controller on it just a simple USB power supply but the switch is mounted at the front so I can slow it down a bit in Winter if I'm on the site, and there's another site with one of those PoE splitter units giving 12v to a case fan that I can turn off with SNMP by turning off the PoE port on the switch.

Interesting that there's products sold for that kind of cooling! 5 or so years ago I wanted some temperature based cooling for my TV stand to keep the video game consoles cool. I searched around a bit for a product that might do that, but ended up just assuming that's not something there's a consumer market for. So instead I made my own basic circuit to run PWM PC fans with an Arduino. It was an interesting project and the end result did do what it needed to but I spent a long time tweaking the temperature response and attempting to get a quiet acceleration but eventually just left it at good enough. It would have been nice if I had run across the AC Infinity at the time. Would have saved a lot of time that I put in for the small benefits gained from adding the cooling fans.

If the foam is too big for the cabinet, take one of the scraps and see how difficult it is to set fire to it.

That is possible even if it does not catch fire, it may still release bad chemicals when heated to an extreme.

@camerongray1515 Жыл бұрын
I'm definitely not an expert, but the way I understand it is that while a 3dB change does represent a halving/doubling of sound energy and a 6dB change represents a halving/doubling of sound pressure, human perception also works somewhat logarithmically so many people see 10dB as a doubling/halving of how "loud" a person will experience a sound as being.

I think that racks like this have a VERY limited cooling power capacity. If you put a bigger, more powerful server in there than what you have, then it will easily and quickly overwhelm the "cooling" capacity of the new fans to be able to draw in enough cooler, ambient air, to cool the rack, which will reduce it's ability to cool the rack. I have I think it's like a 23U networking rack and it has fans as well, but when I had my 8 Xeons running at 100% load in the server rack, it got REALLY got inside said server rack.

Yeah, a rack like this is never designed to run a large amount of high power equipment. For running a lot of servers you're going to need an open mesh rack in an air conditioned room. Racks like mine are designed for running a small amount of equipment where the rack is sitting out on show and needs to look decent. In my situation, it's almost certain that I'd end up limiting what I'm running from a power cost perspective long before I hit the thermal limits of this rack. I would be unreasonably expensive to run anything more than a couple of low power, single CPU servers.

This does have the ability to adjust the fan speed based on the temperature so it's more than a simple thermostat (which is all you could build by using a relay). Sure, the overall cost of materials to build something like this is nowhere near the cost of the finished product, but you also need to factor in that it comes in a nice rackmount case with connectors for the fans and a user interface to allow monitoring and controlling of it. I'll gladly pay extra for that over having an Arduino and a bunch of associated components bodged somewhere into the rack. And sure, I could buy a rack case, display and some buttons and build this myself for cheaper, but it would only be cheaper if I don't put a value on my time which I'd have to spend a lot of to build it vs this completely plug and play solution.

Instead of acoustic foam, you might explore some noise cancellation ideas where you would use a speaker and microphone to play the inverse of the fan noise similar to a noise cancelling headphone. That might work better and wouldn’t add heat to the cabinet.
@camerongray15158 ай бұрын
That wouldn't be possible unfortunately. Noise cancelling headphones work by picking up the sound exactly where it enters your ears and then plays the inverse directly into your ear. When it comes to a whole room you have to deal with sound travelling in all directions, reflecting off surfaces.etc - Sure you could pick up the sound in one location with a microphone and play an inverse from a speaker at that location, but that won't do anything to stop sound that has reflected off of other surfaces.
@BrentLeVasseur8 ай бұрын

@camerongray15158 ай бұрын
Do you have any information showing this actually working in practice, I simply can't see how this could be possible - sound will be emitted from all sides of every single piece of equipment in the rack and then be reflected around inside the rack. The servers will also vibrate and therefore cause everything in the rack to also emit some level of noise. I can't see how some sort of speaker emitting the inverse of the sound picked up at a single location is going to do anything to reduce the overall noise in the room. A similar scenario would be where you have a pair of speakers wired out of phase with each other. Sure, one speaker will be playing the inverse of the other, but it doesn't mean you don't hear anything - the sound level will change as you move throughout the room with some areas being loud, and others being almost silent. Noise cancelling headphones work because your ears are always going to be in the same position relative to the speaker, but this isn't the case when talking about a whole room. The noise cancellation feature on the 3D printer you mentioned does seem to work, but this looks like it's using a microphone to listen to the sound produced and then tunes the motor driver to actually stop the motor from emitting certain frequencies - A clever idea for sure, but not the sort of thing that can be retrofitted to any noise source.
