Supports AMD® Socket : AM4/ AM3+ / AM3

The stock fan that comes with AMD box processor either does not come with any lighting feature or require a motherboard that comes with RGB control function. HIGH POWER® RadiantAM4 has an on-board RGB controller which continuously changes LED light show color on its own.  All you need to do is to plug in the 4pin PWM cable to motherboard's fan connector header and you are in business.  It works even when you plug into a legacy 3pin fan connector. Set your BIOS to silent mode will enable the fan to start spinning at around 500 RPM when it would be amazingly quiet.   Noise level remains to be acceptably low during normal system operation.
