What is that rubber cube that felt out of my bequiet! PSU?
Today I heard a weird noise inside my computer. Turns out my PSU fan couldn't spin up because this 8mm rubber cube blocket it. Seems like heat weakened the adhesive on that cube.
After pulling it out the PSU seems to run normally without any weird noises.
Is it some kind of vibration dampening or any crucial part of the PSU? Just want to know if my PSU is still safe to use.
Thanks!

that’s the allspark
i dunno mate
Tell me you didn’t just use flash photography around CUBE
if it’s just rubber it’s most likely meant to dampen vibrations somewhere, it’s not critical, I would not be worried running the power supply without it
Really tiny Borg Cube. You are about to be assimilated
Ignoring all the jokes, it is most likely some kind of support piece that was glued inside the PSU to either protect a component during transport/shipping or to minimize the risk of the component vibrating and making weird noises.
Either way, you should keep it somewhere just in case the PSU starts making some weird noises – in which case you could open it up and see where the piece should be glued back on. If you intend to open the PSU, take all necessary precautions for working with electricity – the capacitors must be discharged before opening the PSU.
That’s the ultracube
Forbidden sugar cube
From the PSU? I’m pretty sure that’s a flux capacitor.
It’s a cube of shit get rid of it
Its kevin the cube
Most likely a support dampener that is part of the pc case. My lianli lancool 216 has those for the psu.
wow you and PSU’s relationship must be on another level that it let you feel stuff out of it :^)
Honey I shrunk The Borg!
It looks like a cube shaped piece of plastic or rubber.

Looks like a rubber spacer or brace. It probably goes between the fan housing and the case of the psu to make it fit snugly and it’s rubber to either dampen vibration or just fit if tolerances aren’t perfect. I used to work for a company that put hard drives in special enclosures for storage servers and we had a bunch of different spacer sizes like this for different combinations of drive and enclosure. They’re super common anytime you have something that rotates quickly because they’re good at absorbing vibration while holding stuff in place
It’s a pen dude, that should have not been there in the first place.
PSU egg.
ARE YOU USERNAME LADIESMAN217?!? WHERE IS THE EBAY ITEM 21153? WHERE ARE THE GLASSES?!
A lot of hardware has rubber feet on them near parts that move to help stop the vibrations from moving into other parts. My old PSU had them when I took it apart and it will also aid in keeping separation of the electrical components and the case. There should be plastic shielding too however the designer made the one you have. One of the sides on it should look like it has or had glue on it from double-sided tape.

Don’t ask questions. Just throw it back into the psu, before it’s too late!
I have a brace for my video card. Where it makes contact with the card, it has a rubber cube just like this one, with the weakest glue holding it on the card. I’ve had to pick it up from falling and put it back. I assume you have something like that somewhere in your computer and it fell in.
Bequiet answered this questions a few months ago. It is a dampener left in place during the manufacturing process. They changed the process, and this piece doesn’t anymore. Anyway, it is non vital. You are fine
A pen fell out of your power supply

Out of curiosity how old is your PSU?
It’s probably not critical and probably part of noise dampening but you could warranty it anyway. I like to let manufacturers know when stuff like this occurs
Hard to say for certain. Can you compare it to a banana so we can see the scale of it?
Before I read the title I thought you drew that with the pen… I was very impressed.

It’s the Allspark. We must not let Megatron get his hands on it for the sake of your race and ours.
i think you’re good
