They are external ports for water cooling. They allow you to run the pipes to an exterior location, and I have never seen anyone use them ever. I would leave the rubber grommet as it generally looks nicer than the hole.

Probably for external radiotors. Outside of the case you can make them bigger and thus more silent.

Bye ,

Radiators? Nah, open loop. One end to the faucet, other end to the drain. If you’re on well water it goes right back down to where it came from.

Built a computer for a guy years ago. Dual titan X, 3 radiators in a little fucking HAF tower. He bought two exterior radiator mounts

Confused_Emus ,

Was about to ask what one does with dual Titan Xs, but the obvious answer is whatever the hell one wants.

Yeah SLI was still a thing at the time. From what I gathered he was trying for XOC records on liquid. He only came to us because he didn’t want to spend the time building it

fhqwgads ,

This is the correct answer - I know because I was there 10000 years ago and had to decide between this and buying a special case from koolance. Amusingly they still sell one for the outside.

They can also be handy if you have to do anything weird like route display cables from the GPU to the motherboard like for a thunderbolt display.

flamingo_pinyata ,

Is water cooling for PC gaming still a thing? It's been 10+ years since I followed any trends.

DarkSirrush ,

Air cooling and closed loop coolers have gotten better, and honestly no one can afford to spend $3000 to get 3° lower temps any more.

@skulblaka@sh.itjust.works avatar

Only sort of, it still exists but it's a lot more compact now. And not super common as far as I know, like the other poster said here air cooling has come a long way. I've got a water cooled GTX 1080 Ti in my rig right now, but it's basically just a couple rubber tubes coming off the GPU leading to a little square radiator that I have a fan bolted to. It all sits inside the case (or, well, it's intended to... My case isn't quite large enough for everything I've got in it so I've got the radiator and fan a little bit jury-rigged to the front of my case right now. No biggie.)

Sheldan ,

I built a PC recently, and when researching it still seemed a large chunk went with water cooling still. AIO in particular.

FireRetardant ,

Ive used mine before because the rad was too big to fit internally.

I knew someone who had the MO-RA3 through those ports and had it on the other side of the room.
He sold it to another person in the discord server we were in and he actually installed it in his basement directly below the computer on the floor above. Wild

wheeldawg ,

The rubber didn't agree well on my old case. I poked it a couple years ago trying to figure it what it might be and the little triangles has gotten stiff and snapped off on one side, so I stopped poking it.

I was today years old when I learned what they were for though. I knew it was some kind of tube or pipe or hose, but I've spent about 0.3 seconds actually thinking about it so I never figured it out.

DudeDudenson ,

They're also useful if you are doing weird stuff with your PC and you need to run a connector into or out of your pc

Duamerthrax ,

Years ago, I saw someone run a copper loop through this newly poured basement foundation just to use to cool his pc silently.

CptEnder ,

Yeah I remember that post on Reddit. Holy shit my mans literally ran like 1000ft of copper through his ceiling into his house's plumbing lmao. He also had a WILD monitor setup, was more like a pit than a desk.

Duamerthrax ,

Now that I'm home, I can find the post I'm remembering.

oh, no. It's much older then reddit. It was an old Slashdot post from 2009.

If i could show you the amount of awful 5 gallon bucket, recycled tygon and aquarium equipment "water cooling" loops i used to use for shit, you'd probably piss your pants laughing.

Duamerthrax ,

Found it.

Speaking off cooling and piss, I once saw a streamer experiment with cooling a pc with his piss. Well, I'm saying it was his piss. For ToS reasons, he made it clear he couldn't say it was his piss. It was ill-conceived and he couldn't get far enough to actually do a benchmark test.

MonkeMischief ,

Ah, it could be dubbed the Bear Grylls mod.

Nikls94 ,

I used them on my old Build! Pretty neat if it got some light up the back, but I went back to air cooling, so I’ve got then holes of glory again.

bonn2 ,

It is probably an old case design. In the early water cooling days, there would be separate watercooling units that sat outside the case. The grommets were so you could pass your tubing through.

I wouldn't really worry about the dust tbh, you will wind up having to clean it regardless.

snowsuit2654 ,
@snowsuit2654@lemmy.blahaj.zone avatar

This is it! Old water coolers

jalkasieni ,

Specifically, these are for being able to pass in the tubing when your computer overheats playing Counter-Strike 1.5 so you pull apart your 50cc moped so you can bolt the moped radiator to the side of the case since it doesn’t fit inside. At least that’s the only use I’ve actually seen in practice.

const_void ,

Not just for water cooling. It's for cables that pass in or out too.

Reddfugee42 ,

Such as?

Edit: I mean you can contrive something if you're MacGyver but there's no remotely standard use case for that.

BCsven ,

Mine has an 3 position exrernal fan switch for manual control, cable comes out those holes. Also useful for direct header usb that you run an extender cable out to another device.

TonyTonyChopper ,
@TonyTonyChopper@mander.xyz avatar

3 position? all of my fans get controlled in software from 0-100% speed, reacting based on temperature

BCsven ,

While that is an option for anyone, its not something I wanted. Mine is cube with 200mm fan. The lowest setting is fine for the thermals, but if I'm video processing I will toggle to high, but for voice over or a phone call comes in I drop it down low. The random up and down of the fan if left to its own device creates a noise I don't want to deal with.

anindefinitearticle ,

Such as sata cables for quickly hot plugging hard drives you are testing/inspecting/cataloguing and don’t want to open the whole case between each drive, or leave the case open.

DerisionConsulting ,

There were some old PCI cards that were very badly designed, and they required things plugged into them from inside the case, or they needed to plug into things on the motherboard. I had card that controlled Cold cathode tube lighting that could also connect to audio to sync to the music that worked that way

But, the actual answer is that the grommets are for old-school water-cooling.

const_void ,

Anything that doesn't have an external connector or some way to mount one. One example would be if you were using a USB Wi-Fi radio and wanted to connect it to the internal USB connectors but you'd need to pass the antenna to the outside of the case.

And they’re on the back end of the case.

Tarquinn2049 ,

Well, you got the answers you were looking for, here is a different answer. To your other implied question, how to not worry about dust getting in other holes.

Main thing is to develop positive air pressure. You want more powered intake than powered exhaust.

Use fans for all your filtered air intakes, ignore powered air exhaust, run it at lower fan speeds if you can. Air will get out fine. If you force the air in where you want it to go in, dust will only go into the easily removable filters, it won't be on your components. Any extra hole in the case will just be exhausting the already filtered air. Then just remember to actually check and clean your filters. That's the hard part. But if you clean them when they need to be cleaned, you will never have to actually clean the inside or the fans or components or anything else, just the filters.

KeepFlying ,

Dust will get in pretty much no matter what you do. I wouldn't worry about it. If you live in an already really dusty environment then get some sections of filter and attach them inside of these holes but honestly I wouldn't worry.

It's for water cooling loops if you want to mount the rad or pump or something outside of the case. I think it was more common in the early days of water cooling when things were less standardized.

OsaErisXero ,

Not less standardized so much as when the only cooling loops were custom ones and not AIO

Genghis ,

anyone know the name of this case? asking for a friend

jeeva ,

I know the Corsair 800D used to have these. This looks different, but might be in the same line.

WordBox ,

May be a fractal designs model

Zap , (edited )

Definitely an NZXT. Looks really similar to the back of my Phantom 820

Edit: Ya it's an NZXT Phantom 530

Watercooling holes. That said, I've never seen anyone use them. Mounting external rads is a bitch. They take up space. Most people just buy a watercooling compatible case.
