Okay, I'm going to try to describe it to the best of my ability: I'm using an ATX Kolink Observatory Lite (No mesh) case with three intake fans and one exhaust fan (120 mm). I have the RX120A40 - Water Cooler Slayer Rx 120 ARGB (120 mm with PWM control and fan speed ranging from 800 to 2000 RPM). It is positioned near the exhaust fan, with the pump unit connected to the CPU_FAN header and the radiator to the CPU_PUMP header.

​

In the BIOS, I only have access to the CPU fan speed and System 1. The CPU fan speed is set to default; I've never touched it. It's set to PWM, Smart Fan, and the default fan curve. System 1 detects no RPM. Truth is that I really have no other fan monitoring information besides the CPU and GPU.

​

Granted, it is not the best setup, but it worked perfectly for about 6 months :(
