Hello masters! This is the diagram from my motherboard's PWM Controller (Richtek RT3606BC). I experience overheating flags on VRMs, even if it is not literally overheating. There are two NTC Thermistors in my motherboard, on the top side, I measured it with 68k Ohms on ambient temperature, as I put heat on it, its resistance goes down. On the bottom side, there is also an NTC Thermistor with that diagram (above). However, when I measured it, it is constant 12.09k Ohms, regardless of heat. So I suspected that I have a faulty thermistor, so I replace it with a resistor (98k Ohms), but still it shows 12.57k Ohms, so I replaced the R1 with 0.5M Ohms, and I get a constant 67k Ohms on the NTC Thermistor (Resistor) part. Am I doing this right? Hehe. Just experimenting and no advanced knowledge with this. Hehe.
