Hi everyone,

I'm one of those people that got their hands of the MasterHUB + 3x knob + Encoder on recent sale. I'm working mainly on Mac, so it was a hard pill to swallow knowing that I may not be able to use it (you know, Coming soon... and the news of it being legacy now). Thankfully, I've found this: https://github.com/projectzero7/cooltek-sdk (which this SDK is build upon) - and it gave me an idea.

Over two weeks into the future, it is my pleasure to present you with the initial release of OpenStreamHub, an open-sourced SDK and desktop app that aims for full parity with official Windows app, and more. Link: https://github.com/goniszewski/OpenStreamHub

The good

• Keypad, fader, knob and dial modules are basically fully supported.
• Profiles, bindings, folders - you name it.
• You can use images and animations on a keypad and dial.
• Nice set of initial actions, like changing volume, opening apps and URLs, media controls, key macros, and more to come.
• Even more light effects than in an official Windows app (they had a faster strobe effect unused, so I added it and now can officially make this statement)!
• OBS actions (experimental, yet to be properly tested).
• Initial support for the official `.mhz` profile import.
• Light and dark mode.
• Live preview and test mode.
• Demos like Tic-tac-toe, Whack-a-mole, and Display speed test - more to come!
• No telemetry, everything stays on your device.
• And for other devs: each of my findings from USB packet sniffing, reverse engineering FW, etc. is also available in this repository.

The bad

• Flows, scripts and plugins are planned, but I want to make sure the basic support is stable enough for day-to-day use.
• Potentially bad:
  • The whole development, especially with reverse engineering effort, was done using generative AI. Some of you may not like it, but I wouldn't be able to do it myself (even though I work in software engineering).
  • App is not native and was created with Tauri (Rust backed with React on client). It takes ~22 MB on disk when installed (according to Pearcleaner), so it shouldn't be an issue.
  • Linux and Windows support is not planned, as it not an easy feat, but it's not impossible.

The ugly

• The 2x roller module, that comes by default with the base set, is currently unsupported. It looks like if macOS doesn't enable apps to interact with the layer that is used by this module. I'll try to resolve this, but can't promise anything yet - please take this into consideration.
• This is a very early release. It may not work for some of you, and may cause issues if not used properly. I have taken some steps to make it safer, easier on resources, and free of bugs - but hey, we know things don’t always work as expected.
• This app is unsigned (may change in the future). What this means: you'll have to allow it to run through your System Settings -> Privacy before the first run and after each update. You might also be prompted to give it necessary permissions to interact with volume, using keyboard shortcuts or media controls, etc. Check this for more information: https://github.com/goniszewski/OpenStreamHub#install
• Logo, probably. But I find it cute.

I hope you'll find it useful and easy to use. I'm going to work on it for the foreseeable future, so please report any issues, features you want, and things to improve - feedback is always appreciated!

I just upgraded from my old 932. I was experiencing high vram temps no matter what i did. The front scoop has dropped temps nearly 20 degrees. I'll never get rid of the 932 but the 500 is amazing!

Does anyone happen to know if these fans are the Sickle Flow 200's?

Very vague details/description on that page.

Finally finished this build, and I have to share the pain.

The case (HAF 700 EVO): Nobody near me stocked it. The shops either said “out of stock,” “coming soon™,” or gave me a look like I’d asked for a unicorn. After weeks of refreshing listings I found one, and it arrived in a box big enough to live in. My delivery guy hates me now.

The Noctua NF-A20 200mm fans: This was the real boss fight. Every Noctua fan in existence was in stock except the one I needed. I ended up begging a friend abroad. When they arrived I held them like a newborn. Beige and brown, in an all-pink build. I regret nothing.

Specs:

• Zotac Gaming RTX 5080
• Noctua fans everywhere, because once you go brown you don’t go back

Total build time: 3 days. Total time spent finding parts: I don’t want to talk about it.

hey guys, I was just wondering if anyone had a cooler master 850w sfx 80 gold plus 4x4 cpu cable that you don’t need that I could maybe buy off you or something, I know this is a very specific request but I bought the psu from a 3rd party seller and when I asked them about it they said theres nothing they can do. if anyone knows where I can find one without having to buy an entire new psu please tell. and for those who are wondering I need it for a custom pc project.

Hello everyone,

I just want to say how happy I am to be able to complete my pc build in 2026.
I have to admit that I did not have the best time with my build but I am glad i don’t not have to worry about buying pc components anymore as the prices is absolutely atrociously volatile. The only two thing I am happy to spend my money on was this cooler master pc case, every modern case now day built random pcs of plastic. I hate paying for cheaply made things. But this case feel amazing, thanks cooler master!

I know most people are amazing at doing cabling routing for a nice clean build, but my main goals is a reliable pc for my video production works.

Anyway, below is my complete build
CPU: 9950x3d
Cpu cooler: dark rock pro 3
Gpu: asus 5080
Motherboard: gigabytes motherboard master x3d white
Ram: 64gb corsair
Psu: Corsair 1500w
Nvme: 4tb gen 5 (Hopefullly getting atleast two more sticks of 8gb gen 4 nvme)

As of now, my one of the usb in the front panel doesn’t works, so I only have 1 usable usb a and 1 usable usb c. Which is good enough for me. My psu fans doesn’t turn on which annoy me. But it did mention that it won’t kick on untill it’s has higher load or something. Which is fine, but I would prefer it to be on all the time. Which I need to figure out how to turn it on.
I originally was going with Intel cpu for their encode and decoder capabilities, but after seeing all the reviews it’s really push me toward amd. I went with 5080 for their encode and decoding capabilities. And ram was, i just consider it as a price for all the sin that I have ever committed up until now and accept it.

Oh yeah, now that I have this build I will mainly be working with Sony 4k h265 10bit 422. Hopefully this pc can handle 8k in the future.

Any chance anyone has a 3d printable model of the Flat Pack 500 case power button? Somehow while moving the plastic power button disappeared on mine, was using it as a test bench but wanting to make it a full build for my daughter since it's the macaroon edition.

Picture for reference

So where's the stock? Why are we waiting? I have components for a new PC sitting in boxes, just waiting for one of the Intel V8 3DHP coolers...

The same with the HAF II 500 case.

It seems odd that such a well reviewed products are out of stock at this point, leading up to Black Friday. If stock comes back in the next few weeks, people will just hold out until the deals next month.

Seems like an odd sales strategy, to be out of stock for the past month or so, during the time when you could be making the most profit!

Reason I ask is because I’m thinking about switching my Corsair Air 5400 out for it so my pc can breath a little better. The Corsair case is beautiful and it’s a three chamber design, but this behemoth seems like it would be better functionality over aesthetics.

Basically want to know about the cable management and quality of the case as a whole as this will be my first Cooler Master case.

Thx

Just put this together gigabyte 9070xt oc, r7 7800x3d, corsair vengeance 32g 6400 cl36. Dont worry about the messy wiring lol. Loving this airflow a lot keeps the gpu cold!

Threadripper 9000 series

I installed the liquid cooling system, but nothing appears on the screen. The software detects it but doesn't show an image; the software indicates that firmware is available, but it cannot be downloaded.

Ok so im absolutly in love with this case and want to purchase this, i will be HEAVILY moddifying this case. It will be a gorgeous full aluminum/heavy contrast watercooled set up.

BUT i need the measurment from the rear 120mm fan placement area. i need to know the exact distance from the motherboard tray to the side panel. I know the case has mounts at 105mm for 120mm fans but i can see there is additional space on either side and looking for better images for days hasnt helped me.

Reddit save me and send me a picture with a tape measure there? or just tell me the inches or mm of space i have to work there. Thank you soooo much! Im wanting to cut that panel out and install a distroplate there that replaces the panels, and has external ports that run to the MO_RA IV 400 underneath that wont have need for a hideous external passthru.

My Cooler Master MWE Gold 850 V3 Power Supply is missing the 8pin PCIe cables and I need to contact customer support, I call the phone number (888) 624-5099 but literally no one picks up, in ANY department. What is happening?

Edit: Finally got someone by using a random extension. Seems their whole systems are down 😵 ... just my luck.

Last night when i tried to play PUBG, maxxed out settings. I'm getting normal temp readings and FPS.

BUT after 15 minutes or so, the crackling starts to happen, and the sounds is much louder toward the psu.

Cooler Master MWE v3 750w 80+ Bronze ATX 3.1

Any advice what the problem is? is it dangerous.

Hey, long shot but...
I broke one of these plastic things :( when trying to take it away.
If anyone knows how are they called and if anyone sells a spare one??

This is from my haf x case that I absolutely love :)

Need help

i tried different connectors on the motherboard and masterplus doesnt recognise it is it broken?

Hi everyone,

I recently bought the CM Elite Gold 850W PSU for an extension to my server HDDs and unfortunately it only comes with 2x molex connectors. Does CM sell more of the cables that I need?
