There is a review of the Fractal Design Prisma AL-12 PWM posted today at Vortez. Every time I link a fan review I want to use the ol' "does it suck or blow" line like a thirteen years old.
Today we look at Fractal Design’s brand new Prisma AL-12/AL-14 PWM fan, available in both 120mm and 140mm formats and with or without PWM support. They feature six individually addressable hub-mounted RGB LEDs.
