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.
