NEXT WAVE OF DAISY CHAINS Outfitted with an easy-to-manage 8-pin cable that can be chained to each of the FD fans, this greatly reduces the mess of fan wires that need to be managed. SECURE CONNECTION The 8-pin connectors in the fan frames have been greatly improved to utilize a block-shaped connection rather than the straight line found with the FC series. Quick, secure, and simple. COOLING YOU CAN TRUST Equipped with a long-life hydraulic bearing. The FD12 PWM fans boast exceptional cooling specs while remaining relatively quiet. ENHANCED MATERIALS By utilizing an enhanced composite material based on PBT for the frames and polycarbonate for the fan blades, the entire fan assembly is extremely consistent and has a quieter overall sound profile. REDUCED VIBRATIONS Full-coverage rubber pads at each corner guarantee minimal fan vibration and ensure that noises resulting from uneven mounting pressure are minimized. FANS YOU CAN DEPEND ON The quality of these fans will last quite some time, but if anything arises, fear not, as all FD series fans are backed by DeepCool's limited warranty for three full years.
