What’s your budget?

I could recommend lights all day, but ultimately the decision will be up to you. If it were me, I would ditch the HPS altogether if heat is this much of an issue and go all LED.

You must use 42.3w Sq/Ft of the very best LED Diodes to equal a 1000w HID.
Gavita 1700e 645w is a direct replacement for a 1000w Hortilux HPS in a 4 x 4 area. No way around it, though it blows the budget out of the water.
Best budget LED are HLG, and will still be more than a $500 budget. They use Samsung/Osram Diodes. Dont use any other Diode if you want as good as results as HID. But you must use 42.3w Sq/ft regardless. 1000w HID/Hortilux is 1600umol, and 62.5w Sq/Ft.
Gavita 1700e is 645w, and 1700umol
Gonna take about $800usd-$1000usd for the HLG.

Is your 1000w hps cooled ?

Nope, no need for it because we have such a large area, are in a basemaent, which is very cool, and really good ventilation. We also use a Dual Ended 1150w Gavita. We use all 3. 1000w Hortilux HPS
In many cases though you would need to cool them. I think it Takes about 8000btu to cool each 1000w Hortilux

Sell the 1000watt on craigslist and get 2 600 watt hps w/ air cooled hoods. LEDs get pretty hot too.
They do.. but not compared to hps... 2x 600 is a great option... or 3 cmh

I think mars recommends 4 of them per 4x4

No, that light draws 100W according to their website, so even 4 of them would be about 80W shy of what most people would want to run for a 4x4. OP would need 10 of them for 4x8.

I'd recommend 2 @ 630 watt CMH for a 4x8.
Cost about $1200 and would add no more heat than your 1000 watt HPS and an addition Led

Couldn't pay me to move to HPS lol! I started out at more than 1g/w, not gonna go backwards lol. To each their own, as long as you get fat sticky flowers that smell and taste good who cares right?
