[Help] Fan placement for best cooling

[Rakie]

I just ordered a nice little 110 CFM fan, and I'm wondering where the best place to put it is for maximum impact on temperature.

Display -- or -- Sump.

I'm also assuming best to be pointed directly at the water, just not sure which area will have a greater impact. Reef hit 83.3 today, so I'd like to get this down.

I have a similar fan and I installed it to point at the surface of my DT at an angle to cool the water since that is where the most water volume is contained. It works for me. With your temp hitting 83.3, you may need something a little more effective. Either it is very warm where you are or your tank is surrounded by people

So Cal heat wave. And my house is OLD, and holds temperature... When it's hot like this, the house doesn't even have a chance to cool before the next hot day starts.

I had an idea you were on the West Coast. Although it is hot there, I envy the weather
Hopefully the fan works. Temp here has cooled a little so my heater is active now. Hopefully the fan works for you!
