I was removing the stickers from my Cooler Master Halo2 fans and noticed that this metal piece is loose there’s no glue residue at all. Does this mean the fan is held in place solely by a magnet? I also took the opportunity to turn off all the LEDs 😅 they distract me; I have ADHD.

Hello,

In a previous thread 2 years ago, someone asked if CM was going to sell the side panel separately for those wanting to have all metal panels instead of glass on the QUBE 540. Unfortunately, it looks like it’s still not available for sale. I would have to order another case just for the panel. I honestly wouldn’t know what to do with the second case with just glass side panels since prices to building PCs keep rising.

Does anyone know if it’s still in the works or being discussed to sell the side panel? Thanks, I’m going to contact CM customer service soon too but wanted to check here first

Suspicious WinRing0x64.sys <- coolermaster ring0 driver, not signed, not authenticated.

It is now blocked on my system, and should be on yours. Coolermaster software is just a virus waiting to happen. Fix your software coolermaster. I've been asking for a year now. Just fix it. Your hardware is kinda ok. Your software bites.

My HAF finally came in. Simple, Large, and in Charge. 😤

Found this new old stock V8. Just admire the look

hello please how can i buy two separated Cooler Master Mighty40 V180 fans i need put in top of HAF 2 case

Got this hyper h410r 2020 model , whether they make any trouble in long run.

HAF II 500 With NH-D15 G2 chromax.black

Its much cheaper than elsewhere online, theres barely any reviews also the logo is missing?

I've had this thing for a while now, and it's gotten pretty dusty so I wanted to clean it, but I couldn't find a way to open it up. Can somebody help? Thanks

Has there been any confirmation that Cooler Master will release either version of the Mighty40 fans? (220mm or 180mm)

They're currently at the same price and I honestly don't know which one is a better performer and quieter.

I don't care about the stock fans as I would replace them with Noctuas.

Which one should I get for my 9800X3D in a SFF build?

Are these worth it ?

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.

It doesn't display an image; only the logo appears upon startup. There is firmware available on MasterCtrl, It shows me available firmware, but the download button takes me to the website.

Jokes aside, the Mobius 120 really impresses me even though it is not new in the 120mm market.

For around 13 bucks a fan, at loads, it is virtually silent when compared to the 9 bucks P12 Max that I owned. The fans do push quite a lot of air and the only thing I can hear now is the coil whine of the GPU. No strange bearing noise at low speeds, no annoying resonance hum at moderate loads, and the build quality is extremely nice.

The switch doesnt seem want to lock on any mode physically, then the usb dongle,the wired and the bluetooh all dont work and cant connect to my laptop at all.

When i plug in my usb C and/or my usb dongle, my laptop says "USB has malfunctioned and unrecognizeable"

How do i fix this?

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!

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

Very vague details/description on that page.

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!
