I bought this and found out a standard 1 inch thick fan was too thick, had to use a slim fan instead. This fan has not been installed or used. I have two of these installed on my 240 radiator and they really work great. Love the high static pressure and extra air flow.

The EK-Vardar EVO 120ER D-RGB - White is a white-framed version of the high-static pressure computer cooling fan, designed and built primarily for highest-performance computer liquid cooling systems. Besides the addressable D-RGB lighting that can be daisy-chained, the new fan also packs the Extended Range (ER) of the PWM operation feature and the special Start-Stop function which brings a true 0dB experience for the absolute silent fan operation. EK-Vardar EVO 120ER D-RGB is simply the best choice of addressable RGB fan for computer radiator cooling as it provides unmatched performance throughout the entire operating range.

The perfectly balanced milky colored 7-blade impeller design is optimized for light dispersion and high-pressure operation while maintaining the low noise profile throughout the whole operation range of the fan. Under the motor hub, there is a total of 9 LEDs making this one of the brightest D-RGB fans on the market, ensuring perfect light diffusion at broad daylight as well.
