Best fan to use with Hydros Controller

[SteveMM62Reef]

I've used this fan for 10 years and never had an issue with it breaking, plus its more powerful and cools down tank very quick. Wont work with the port but reliability IMO is more important

I have one of those, sets on the floor behind my Aquarium. It’s positioned so it blows into the cabinet and across the back glass. Effective for cooling the Aquarium, when I’m in between Cooling and Heating and the Dehumidifier is running.

Very timely - it's hot this week in SoCal and my tank is currently at 82F. What do you guys recommend for a 450g? I do have a 3/4 chiller but don't want to drill a hole thru stucco.

How do you connect these to drive ports?

Am I missing something here, because it looks like the W-4 is physically larger, but moves less air?

I need something to blow air out of my canopy and I want to sue the Hydro to run it.
