Phanteks T30-140 PH-F140T30_BG 140mm Case Fan, 30mm Thick, 139.6 CFM Advanced Mode, 3-Mode PWM, Black/Gray

This is a good deal on a highly-regarded 140mm PC case fan. The Phanteks T30 is known for its excellent performance and quiet operation, and a 25% discount brings it down to a competitive price point. While not an all-time low, it's a solid saving for a premium fan.
