Chassis / fan Noise

Hey sleepy peeps. My Hypno makes a weird buzzing noise that is clearly fan related. It’s like its rubbing against something in the chassis, but it only happens occasionally + persistently. Changing the orientation of the Hypno disrupts the noise but it comes back until it decides it doesn’t want to. Strange! A video is below:

Any suggestions?

We def check these to be sounding ok in factory so it sounds like some debris something fell into the fan? Please try to keep it clean & blow it out. Otherwise I can advice on a replacement fan. Or I guess you can also try poking at the metal enclosure of the fan and make sure its not in the way of the blades it is metal so its possible its deformed slightly but not sure.

(next time please just upload a private vid on YT or something; whatever this service is its very stingy w bandwidth, I got 450kb down max on your link so it took like 30 min to get)

I actually joined the forum because of this exact issue. I have had it for less than 3 days and have ran into the same issue. There is zero possibility some “debris” fell into it. My guess is it is something to do with the inset of the ethernet cable, maybe it shifts the inside of the unit, as that is about the time mine began to buzz. Reorientation corrects this.

Yeah I also kept mine quite clean so I wasn’t buying the debris thing. That having been said, it continues to happen and then quiet down to silence within 5-10 mins. Reorientation does change things, but so does just letting it buzz for a few mins. At some point I may do an internal investigation but for now I’m okay to let it ride.

I do think it has something to do with the slight force of inserting/removing the Ethernet (or other) cable/s and when it clicks into place it’s inset enough that you have to slide something just above the cable to release the lock on the port to remove the cable. I just don’t quite understand how reorienting the device stops the noise, shifting it to the left or right on a flat surface can stop the buzzing. Just an odd quirk, and one I cat make sense of. Having said all of this, the stress of such an expensive device exhibiting behavior it shouldn’t is well… it’s not nice. Were I more paranoid I would’ve likely contacted the company I purchased from. For now tho, if it isn’t a problem that leads to other problems, I am content to let it go.

I can’t speak to your ethernet port theory - I’ve never used the ethernet port! This started happening for me independent of having ever used it.

Same issue here. Batch issue? I’m in Europe but mine arrived yesterday. Haven’t used the Ethernet port either, was like this straight out of the box.

Okay it is still happening. I let it go for a bit, ported a bunch of shaders and fx, and now I’m using it regularly in a large project. I have a few more issues:

  1. It is an absolute mystery how this thing turns on and off. I know that’s odd but sometimes I have to plug and unplug it several times to get it to come on. A couple of times I’ve gotten fatal firmware errors.
  2. It always buzzes. ALWAYS. Sometimes it sounds like a small drone.

I attached an unlisted YouTube video of the noise and showing the power source:

Right after I made this post it crashed so here is an example of power issue:

Hey can you please send me an email about this to support@sleepycircuits.com, it seems like we may have a malfunctioning fan and perhaps SSD also and that would be the place to open a ticket about it so we can fix it. Likewise for anyone else experiencing similar issues.

Also from the vid it doesn’t appear like you are using the supplied PSU, please use that one for most reliable operation, the 5V5A rail Hypno 2 uses is not a very common one and its likely being underpowered if youre not using the supplied PSU which would explain the instability.

Any resolution on this fan noise issue? I received my hypno 2 a few days ago, and there is constant extremely loud fan noise. I have emailed support@sleepycircuits with link to supporting videos but have not heard back.
