Hey Steev, nice to see you :), because of heat, I record in shorter takes, and if someone likes to sing none stop, between their records I ask them to take a short break and I keep its door open to refresh the air and it also becomes cool with the AC that I have in this room. and also I usually pre cool the room before records. K240 was new for me as I always used closed back headphones, but I am getting used to it now, it has a great quality.
