I have a corasir h55 in my computer and it is very very loud. When my pc is idle the stock cooler is quieter, but under load the h55 is quieter. In Speedfan it always shows the h55 running at 99%
How can i make it quieter?

How did you plug in the parts.

The pump should be plugged into a header that is NOT controlling the fan speed or even the power supply if you have the adapter to do so.

Now the fan may not be pwm(unless they made changes, it has 3 pins). Please check the bios to see if you have fan control options for Voltage control instead of PWM. If not, you may be able to use other fan headers in the system if they work with voltage control.

If all else fails, getting a 120mm fan with PWM will bring back control for sure.

I plugged the pump into the cpu fan header and the fan into the system fan header

k, does the bios allow you to set voltage control for the fan. Without it, the fan will run full speed all the time.

The manual would indicate that your board does not control the speed of 3 pin fans. This is why it is always loud.

Your options are to.

A. get a fan controller(would allow you to adjust the speed to whatever you want) or fan speed adjustment cable(most give you at least an option to run the fan at 5 volts[much slower and some fans do not start on 5 volts, but will always ruin that speed]) Some even give you 7 volts as an option. Placing a 50 ohm resistor in line with the fans power would also slow it down to about 1200-1400 for most fans of that speed.
B. Get a PWM fan(like the NF F12, SP120 or even CoolerMaster Blade Master 120) OR get a quieter fan that you can stand to hear at full speed.
C. Build a PWM to Voltage converter. This is a DIY Project and only recommended if you like DIY stuff.

Link1 A high gain transistor or 2 in a Darlington configuration is required (the plans withe Zener Diode on page 2 do not need high gain transistors)
Link2 This guy makes and sells adapters, no clue what the shipping would cost. He also has the plans showing. A higher gain transistor never hurts with this plan as well
