Yep those babies are rotting. As for lowering the temps I'm not so sure, I'm currently facing temps of 78-82. I moved a portable AC unit into my room but I'm having trouble expelling the hot air generated from the AC. CoolWorks makes a thing called the IceProbe for smaller sized reservoirs that will cool your res down to 65, but its like $130. Other than that I'm at a loss.
