I have a 65 gallon tank. I am thinking about upgrading to a 6 bulb 216watt T5HO system, would this cause my water temperature to rise significantly?

The exact system is a Nova Extreme Pro T5HO 36" 6 bulb 216watt.
 
No. Not with T5's. You will hardly see a raise in temperature, and if you do at all, it will be negligible. Maybe a degree or a degree and a half.. if even that. I wouldn't worry about it at all.

I had the 48" Nova Extreme Pro over my 55G and i didn't see any temperature changes at all actually. It was always at a constant 79*. I did not have fans running over the tank or anything like that either. T5's do not put out much heat at all.
 
Deep blue t5he 2 bulbs is my current setup. I want to keep an anemone so I want to upgrade my lighting.
 
Go for it. That's enough light and the T5's are great at running cool./

I upgraded my lights with a retro DIY using 4x80 t5's from VHO's that came with the tank. Now, VHO's run hot and there was one fan, I installed two with the new lights. Initially had a problem keeping temp up! On a warm day at that. Big difference. I honestly question if I need both fans at all.
