FK23 High-Performance Cooling Fan Kit - 160 CFM Quiet PC Case Fan for Gaming, Workstation & Home Office Use

I have asked for a replacement. It started out very noisy. I had to turn the TV up to hear it. I only had 4-5 fires in my fireplace and then it started squeaking loudly and wasn't blowing out any air at all, like it was barely turning. I had to turn it off and on several time to get it to run and then the loud noise again.The vendor should not state that this is a "factory replacement" for this unit the motor and bearings must be very cheaply made.Not satisfied at all with this. Maybe it is just a defective unit. I hope they will replace it and see what happens.
