Squinty BT

I love this case my only gripe is it’s super heavy

I'm getting higher Idle Temperature on my Coolermaster Masterliquid iON 360 coupled with AMD Ryzen 7 9700X. I'm getting 55-57°C at idle condition with zero load, all startup apps are disabled.

Repasted with Noctua thermalpaste and reseated not going beyond 85°C at load but this 55°C is at least 8°C more than I was getting earlier (45-47°C).

Hi everyone,

I’m writing this as a warning to anyone considering the Cooler Master SK620. I’ve been using mine since October 2025, and it has officially become a paperweight.

The issues started after just a few months:

The most alarming part: I spoke with the retailer where I bought it, and they told me that nearly every single SK620 they sold was returned for RMA within 3 to 4 months. This isn't just a "bad unit"—it's a fundamentally flawed product.

To make matters worse, trying to get actual support from Cooler Master for this specific model is a nightmare. There is almost zero official help for these issues, and the firmware updates don't fix what is clearly a hardware/PCB failure.

Verdict: Save your money and your nerves. Stay far away from this model and perhaps Cooler Master peripherals in general if this is their standard for "quality." If you need a reliable board for work, look elsewhere.

Got hold of a coolermaster vertical gpu kit v3 gen 5. Was a breeze to install and fits the O11 evo rgb like a glove. Gpu positioning inside the case is fully adjustable also which gives the user a lot of freedom for placement. I installed it initially at the bottom slots then realized later that I can actually move it up to give more clearance between the bottom fans and the kit.

Spent $50 on a cheap external monitor, a couple bucks on filament, and a bit of time modelling so I could make this custom LCD side panel for my NR200P Max. It protrudes about 4mm and give basically the same clearance as the tempered glass side panel, so temps are virtually unchanged. Prints on three separate plates and glue together. Snaps right into the side panel snaps(which CoolerMaster provided files to print extra).

Hello everyone,
I was wondering if these covers of the Atmos II were really included in any model you buy ? (VRAM/pixel/LCD)
This will help me to determine if I will buy it for my T1 build.
Thanks for your help!
