      The fan might be sound tbh but you don't wanna use that controller buy an str step controller and wire it in where the dimmer switch is now.   I'd tape that join in the casing too as it looks like it's had a few knocks so might not be airtight anymore.   It's gonna sound loud as it is, any fan without a filter attached will sound like Concorde taking off.  The controller on there will be creating an extra buzz too.  But stick a filter on it and turn it down to setting 1 or 2 on an STR and it will be quieter than the 4inch your running now and shift 4 x the amount of air.   2p

      Forever Purge.  Decent rip, dont do cinema that much, was good. Could've done with a bit more gore but overall 8/10
