190 cfm fan will never cool a 1000w HPS, let alone ventilate the room. You need a 400 cfm with all 6" ducting at a minimum.

It will always be hotter under the light than your ambient (intake) temperature. @Julius Caesar is correct, your fan is inadequate. Centrifugal blowers work best.

Really need some help on water cooling..... On my 3rd grow now and have decided to switch from a/c to water cool. I run aeroflo 60 only using 3 tubes and 15 sites, indoors with orca film on walls and floor, 8" raptor hood, 1000 watt phantom ballast, cyclone chiller for nutes, 4' can with 750 cfm fan, and with switching to a to water cooling ditching a/c and all vents. Live in socal desert so hot as hell, here. Ok so I bought a 11x10 titanium heat exchanger with copper fins used in the food industries, 1/4hp hydrofarm chiller, 55 gallon drum (res), aapw1000 active aqua pump (submersed), general hydroponics tnc 1/4hp pump, insulated 1/2" line and grozone TV2 controller. Run the pump aapw1000 in the 55 drum and out to chiller and back, the gh tnc pump is drilled into bottom of drum outside feeding the heat exchanger hooked to the raptor hood at one end and the other end has the 750 cfm fan hooked to the TV2 controller. Can't seem to keep the room in themrange im looking for 76 night and 79 - 81 daytime. I've tried this in every configuration I can think of;
1) aapw1000 to chiller to heat exchanger and back
2) aapw1000 to heat exchanger to chiller and then res
3) put two pumps as stated above
4) Adjusted fan speeds up and down
5) adjusted aapw1000's intake from max. to min.
6) Ran 3/4" pvc from the tnc pump up and over to heat exchange and then back to the 1/2" insulated line.
7) pulled instead of pushed air through the hood
Went from 25 gallons in drum upto 50 gallons (per hydro innovations technical support)
9) 1st attempt at thismwas the reason I spent $675 on the titanium copper coiled heat exchanger was so I could hook upto hood run straight down to my nute res (standard 40 gallon aeroflo 60 res) and back down to it using a secong tnc pump in the drain port ( for you guys that know gh aeroflo 60). Problem there was the 1/4hp cyclone chiller cannot keep up, with heat exchange and would raise res temps to 74-76 didmt want to risk root rot. Soooo I scraped that and bought the extra chiller and pump just for the heat exchanger.
Any help or ideas would be greatly appreciated, seems like this is definitely the way to go and there seems to be some guys on here thst really know there stuff. Respect
