Ive purchased this fan in hopes of it being a decent fan.. its loud right out the gate i gave it a fair chance because i was having nice negative pressure after a few months this fans so dam loud its starting to heat up the main bearing causing it to become louder and possibly a fire hazard.. when i contacted mars about the issue it took them nearly 3 weeks after they said they would replace it under warranty but never did and issued me 30 dollar refund. Updated.... they contacted me to reconsider their offer and willing to change/replace the defective fan i have so i say thank you for the customer service
