Is the added heat even worth it when adding cfl side lighting in 3x3 tent with 600 watt HPS

I am currently flowering 1 plant in a 3x3 tent with a 600 watt HPS, I have tons of CFL bulbs just sitting in boxes, leftover from years ago when I first started growing. I would really like to add a few of them to the corners to get more light into the canopy. With just the 600 watt HPS the temps are perfect 76-78 degrees, I would like to add a few of the 42 watt CFL's to the corners, so that more light can get into the center of the canopy, but by adding just 4 of the 42 watters (1 in each corner) it brings the temps up to 81-82 degrees. My question is this: what is more important? keeping temps cooler in flowering, or adding 160 more watts of light?

I know this is a rather stupid question, I am probably just going to leave well enough alone and be happy with the 600 watts. I already lollipopped this plant, basically took off the bottom third of the branches and a few inside bud sites, but the center looks dark to me. I am probably overthinking the whole thing. I have the HPS hung @ 20 inches above the canopy and everything is moving right along.

I run a 600 hps and would never even consider adding supplemental cfl lighting. Save them for seedlings.

Thanks, I did take them out.
