Wow!! Waaaaaaaay to much info for this lil black duck to comprehend...
So its basically , measure both IN and OUT temps for the fans on outside of box and they should be within a degree or so of each other , if not then you need a bigger exhaust (im guessing exhaust) to displace the hotter air...
Cheers for the reply
Ive got myself couple of the 415w , so far only running one light in room ( room only a cupboard around 2f x 3f x 4-5f )
Noticed straight away on first day the amount of heat being produced and was kinda shocked , but after reading your comment re same wattage devices...

Was wondering if heat has been an issue with you in your grows with the intelligent led? If so what have you done to keep a cool room?
Thanks in advance
