H100i v2 too loud
H100i v2 too loud
I have a h100i v2 cpu cooler, and initially I chose quiet mode, but it was surprisingly quiet. Now after two months it’s still quiet but much louder, with idle load showing 1200 RPM fan and 1950-1980 pump RPM. It seems excessive, though I don’t want to risk overheating. The fan is set to 60% at 40°C. What should I adjust for better silence?
The CPU is fine for daily use (up to 90°C for testing). You might be exaggerating. It could be that the fans are faulty or the thermal paste wasn't applied properly. Cleaning the radiator could also assist. Also, maintain static pump speed; dynamic speed may damage it. Only adjust fan speed.
The CPU is fine at 80c for regular use (up to 90c during testing). You might be exaggerating. It could be that the fans are faulty or the thermal paste wasn't applied properly.

I'm just irritated by the noise. If it bothers:
1. Reduce the speed (I'd turn it off or keep it at 40c.)
2. Use fans that are quiet (under 20dB should be almost inaudible)
3. Wear headphones.
The fan speed on the H100i V2 is set by the coolant temperature, not the CPU temperature. This setup is actually advantageous because the fans help cool the coolant rather than the CPU.
At a coolant temperature of 40°C, the system will automatically increase its cooling performance.
The reason you might reach 40°C for your coolant temperature could be due to several factors:
1) The pump isn't receiving the correct power. It is connected via the fan header (usually CPU_FAN), and it should consistently provide full 12V. Setting this header to maximum speed helps.
2) Other system components generate heat, forcing the radiator to warm up. This is normal, especially after gaming, and often leads to higher radiator temps. Some users have reported needing adjustments for airflow.
3) The pump may be clogged or failing, causing immediate high coolant temperatures upon startup. This is frequently linked to the first point.
The built-in fans are known for being very loud, while the ML fans make a much quieter operation. If you share more about your setup—such as the case model, cooler design, and any additional fans—we can provide more targeted advice.
