Kingwin Thermal Center CT-02S Review - Removing the Alarm
(Page 5 of 6 )

Critical temperature alarm
I decided to remove the alarm from my controller. My main reason for doing this is that I want my system to remain silent when it is idle. I also want the system to automatically increase the fans' speeds when the system becomes warmer, such as playing games, or encoding video files. I had noticed that the alarm's speaker was a two piece design, and should be easy to remove. I used a pair of pliers, gently held onto the speaker, being sure to not make contact with the board of the controller, and gently pulled the speaker off. If you are not careful you will end up removing the base of the speaker, and will never be able to reinstall it as I did the second time.

My modified controller with the alarm speaker removed.
After removing the speaker, I hooked my controller back up, and set my system to idle. When I saw my idle temperature, I knew I would need to set my critical temperature a few degrees warmer. I set my critical temperatures 8C higher than my idle temperature so that I can run a few applications without having my fans kick in all at once. The fan speed will still increase at the appropriate scale until it reaches my set temperature, then run at 100 percent to keep the system working at its normal temperatures before I installed the controller.
