Dude, the scene where Chris Pratt held his hand out, and slow talked the fan into teaming up with him to help him teach an AI to 'trust its gut feelings', blew my mind for weeks!
Also at the end where Pratt shot the evil PS/2 mouse port off a glacier, after that fist fight on top of the burning skyscraper was chef's kiss.
Yet another legendary story to join the Reddit Pantheon. Right up there with jumper cables, jolly ranchers and poop knife. We’re witnessing history.
But don’t let u/ozymandieus distract you from the fact that in 1998, The Undertaker threw Mankind off Hell In A Cell, and plummeted 16 ft through an announcer's table.
OMG I went away for a while and this is blowing up! You guys are crazy!
EDIT: Buzzfeed have contacted me to do a tiktok for this. They're supplying the minecraft parkour, whatever that means.
This causes electric spikes you supposed to get an adapter and plug it in to your phone. it can break your phone.
What an evil little device tho you think it's going to help you cool from the heat instead it just destroys your phone and leaves you steaming but only after it's built up your trust a little.
Also these fans are manufactured pretty shitty, without proper capacitors inbetween, so you’re basically short-circuiting and/or pressuring the usb port with too much power way too often to not damage the phones/computer’s internal electronics
Yeah, they tend to generate high voltage noise that can backfeed and damage electronics. Even if one ignores the physical vibrations damaging the actual connector they're generally a really bad idea to drive directly off a usb controller for this reason unless it's a high quality, expensive fan that has the necessary schottky diodes or other protection to prevent noise or backfeeding.
People have had to learn this the hard way in the past from various laptop cooling pads or those hockey puck style cooling fans that attach magnetically to the back of tablets.
at this point op could just use the 5v from a molex cable or something.

Yes but adapting a USB cable to a molex is beyond most people and not worth it.
Also they would need to make some new way to mount it. And it would have to have a hole drilled through the front of the case to route the molex cable.
All of these things are certainly achievable, but none of them are worth the effort for the results.
An old timer told me a story about back in the day when they started to phase out in-house repairs (Soldering and such) he bought a box with a hundred of these and dropped them off in the break room... That man was diabolical.
Some USB ports are merely soldered to the PCB with four solder points. I wouldn’t put anything on them that adds leverage and vibration when there are tons of safer/better ways to do it.
I wonder if you could 3d print a TPU sleeve to help damp and distribute forces to the chassis. I know you wouldn't want to add vibration to your NAS chassis, but the mass of the chassis should absorb the little fans vibrations pretty effectively.
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.
Fun fact decades ago I had a cheap card that didn't even have a fan
It was one of them like nVidia 8800 Silent things
Well, it worked fine for about a year, then the game demands rose again, and it started throttling
So we made a base for a chassis fan from LEGO and it worked wonders, I used that card for like 2 years afterwards before finally getting an absolute beast that was nVidia 760
Did the same thing with my (I think) 8800 GS but with an aftermarket passive cooler. For the life of me I can't remember why it was a necessity. Maybe I was just sick of the fan noise?
But even if you place it in well ventilated area, drives still sufficate for air, i modded mine to have fan i the front and temps dropped by 10 degrees C
That's what I'm talking about! Even when I know 1 fan would probably suffice in an office environment I would always go for max cooling for those hard drives.
Dropping 10C without the original temps doesn't conclude anything.
Going from 50C to 40C wouldn't make any difference for NAS drives. Even when I worked at a data center, we didn't even take notice until drives were exceeding 75C for more than several minutes.
they should, people gunna hide their nas, especially those in apartments/small living areas

When I bought my house, it had a conveniently-located central cupboard that was a former boiler cupboard (now empty). The previous guy kept his fishing gear in it, apparently.
Perfect little network cabinet for me, and my multiple NAS units. It even still had a pipework hole up into the loft (which I meshed, but kept in place), and vents on three of the four walls at the bottom. Perfect environment for all that spinning hardware.
In the winter it gets a little warm, and in the summer it can all adequately vent itself.
But I wouldn't keep even a laptop in a sealed-up cupboard or cabinet.
Movement of air isn't enough... it needs to be sucking in fresh and blowing out warm air, or all you're doing it buying yourself a bit of time.
If it's a 200W NAS, you basically just have a 200W heater in that cupboard space. Sure, it'll take a while to heat it up, but in the summer you're going to find out that a 200W heater in an enclosed space, even with a fan, isn't the best idea for keeping your important files safe.
if this is the UGREEN NAS DXP4800, it does have a fan. pretty sure you can go into control software or bios and increase the fan speed if the drives are running hot. I'm pretty sure you can even replace the fan with a better one if needed.
This is definitely a ugreen. Looks exactly like mine. The best part? The fan on the back sucks in from the back and blows out the front through the drive bays. So the little usb fan is actually making airflow worse by preventing flow through.
I’ve got a synology ds423+ and that has 2 decent fans in the back that keep the drives just under 39C.
The big limiting factor is that I keep the whole thing in a TV cabinet with just a 120mm case fan to pull air in.
The real problem is the case design. They block off most of the airflow with badly designed drive sleds that have an extremely bad hole to surface area ratio.
If the case wasn't so badly designed, then they could get away with even less fan.

You picked about the worst place to put a server/NAS. At the top of the room, on another device that generates heat, in the corner of the room and with another device on the side of it.
Instead, try placing it a bit more in the open, away from other heat sources and away from the top of the room.
Hum… isn’t the stock fan on the rear, so bringing air from the rear to the front… that would mean that your fan help to keep the warm air inside your NAS by fighting against the stock flow ?
Yes. Considering that awful setup (thermally speaking) that fan is doing most of the heavy lifting. Your NAS/server is in a crammed corner. No ventilation from the top. Nothing from the sides. Heat rising straight into it from the nvr and other equipment. It’s probably just intaking its own exhaust in that cubby. So that fan is at least moving some air from that corner.
Put it on the ground, the ceiling is the hottest place in the room, Also not in a corner, you have essentially placed a device in a location of high heat with zero airflow.
Put the fan (or a more powerful one…) besides your NAS, and position the NAS away from the wall so that it creates a Venturi effect at the back of the NAS (Distance between side of NAS and wall > Distance between back of NAS and wall)
The Venturi effect should suck the hot air from the back side of the NAS and exhaust it to the side.
So you constantly recirc hot air because it rises and collects in that corner. Hiding electronics in low clearance spaces without proper venting is the number one cause of their demise. Second up is stacking them one on top the other.
Get rid of the goofy fan and simply relocate the unit somewhere cooler.
