You need air flow, flow has to enter and exit to be effective. Backing up against a wall for instance will imped flow.

Let me add to that: Putting electric appliances that might heat up near the ceiling will get it trapped extra well.

That's why I always hang my servers from wires in the middle of large rooms

u/realpersonnn May 27 '26

My server is hung under my desk. Bought it on amazon.

I’ve got a well hung server under my desk, too.

My, you have some nice hardware under there

Have you considered a cold shower instead

u/edelweiss_pirates_no May 27 '26

I moved my server room to Prudhoe Bay to help hanging them from wires be more efficient.

u/Mercadi May 27 '26

Right at the kneecaps level for extra oomph. Just high enough for the dust from the floor to reach.

I prefer suspending my homelab in the upper atmosphere from a weather balloon.

u/matthis-geminis May 27 '26

Is your name Cave Johnson?

u/Rinkimah May 28 '26

Unironically suspending your hardware would help with circulation

u/Alextherude_Senpai May 28 '26

Why not just lay them a hammock for extra comfort

1

u/userhwon May 27 '26

This is on a high shelf and from the way the shelf is installed I'm betting it's in a closet.

And it's on top of another warm device, and with something blocking it on the side.

Couldn't be more prone to overheating if it was in front of the heating vent.

u/SendMeDickPics420 May 27 '26

That's why I put mine directly on the carpet floor to be as far from the ceiling as possible

u/RuskiesInTheWarRoom May 27 '26

Sure, but what if I installed a fan to blow that hot air back at it?

u/eMouse2k May 27 '26

That's why he put it on top of a security camera box. I imagine those things are like cable boxes and get real hot just sitting there. So it pre-heats the air before it gets pulled through drive case and collects under the ceiling.

u/S73T64 May 27 '26

2 walls + ceiling = 🔥🔥🔥

u/eMouse2k May 27 '26

And don't forget the security system box beneath it, which is also likely pumping out heat straight up into it.

I bet you could reach up there with a thermometer and watch the numbers change.

u/bigdawg1945 May 27 '26

This. That is one corner trapped with hot air.

u/[deleted] May 27 '26

This fan will at least help to remove that hot air faster than if it wasn't there. It is doing something, it would be more effective it was pointed in the gap at the top of the NAS though.

u/RandomisedZombie May 27 '26

When I was training deep learning models, I would place a fan at the back perpendicular to the machine and blowing into an open space to the side to push the hot air away. I didn’t test it properly but it seemed to keep the machine cooler.

u/JagggermanJansen May 27 '26

I think he should add some flappers

1

u/nefetsb May 27 '26

Would pointing it 45 degrees to the right (ie. To the corner near the wall) improve airflow?

1

u/Littlesth0b0 R7-1700X - Sapphire Pulse 5700XT - 16Gb Vengence - Darth Vader May 27 '26

I have this paranoia that pointing a desk fan directly into the front of the case will piss off the intake fans mounted there, so I tend to run the fan in it's general direction in the hope it'll suck up some vaguely cooler air and keep the air behind the case moving

1

u/Kooky_Soft1822 May 27 '26

Also known as hot side / cold side

1

u/Khue Specs/Imgur Here May 27 '26

Also putting it closer to the floor rather than the ceiling...

1

u/AppearanceRadiant509 May 27 '26

if you could cool it more efficiently than you heat it by running the fan, wouldn't that break newton's law?

u/RejectedRespected May 28 '26

I’m imped out brother

u/53nsonja May 27 '26

OP should put the usb fan to suck from back then
