I think a 182 with fans on low, during a summer in gaming rig will be too toasty inside. But then on medium or high though.. annoying the HD fan doesn't have the switch at the back, unlike the two upper fans.
using a 182 for my htpc, how much quieter are "very quiet" fans ie the 8db noctua, compared to the 182 rear (single one only) on low? The inner fan doesn't cause much noise, since it's inside the unit. The loudest producer of noise is the rear case fan.
