Dial the Drivers down and efficacy will help with the excessive heating during the warmer temps. Some LED fixtures have drivers that are removable and they are best remotely placed outside of the room just like the ballast with the hid lights.
I don't think that there's many hacks, but blowers and fans are a good thing to utilize. I keep my QB Bank aligned with a blower and the ventilation keeps the temps a couple degrees by simply venting out of the room.
One thing I can say that I have observed throughout a couple years of using only LED is that the plants do much better in the heat under LED then when growing under the hid lights.
