Hello, I've just transferred my previous setup into a new NZXT N1 (the smaller model). The CPU fan is spinning erratically, ranging from 1200 to 1500 RPM at idle with a "silent" setting (temperatures between 45 and 55°C), reaching up to 1800 RPM when the CPU load is around 20% (up to 60°C). The speed curve seems unstable, and the fan noise is fluctuating up and down. It's powered by the NZXT C650 SFXL case, which includes a 140 all-in-one CPU cooler and the motherboard with AORUS B450i Wi-Fi. My motherboard only has one CPU fan header and a system fan header, so I've connected the CPU fan to CPU_FAN and the pump to SYS_FAN1. I've also lost the original backplate and screws, so I'm using four random screws for support. I'm curious if my temperatures and fan behavior are within normal ranges and what might be causing these issues, along with possible fixes. Thanks in advance.
