I was looking at going with the Tek 6 bulb unit for my 75 gallon tank. I don't have a canopy and set the light over a glass cover. It doesn't look like these lights have a fan but supposedly they have cool operation. I really like the idea of no fan noise. Do they really run that cool to where they don't need a fan? I'd leave about an inch space above the glass top.
If possible remove the glass top from your tank. It blocks out the light and it also helps with gas exchange to not have one.
You will need to run fans of some kind with that fixture. They actually get pretty warm and the heat causes issues with for the bulbs and ballasts.
