roasted!

My heat output is erm, rather a lot. I just got the patcom, and i was taking it out for a spin, after loading it up, and i got loads of “critical heat” messages. Clearly the answer is heatsinks, but which is the best? i currently have a gamma-sink, and a closed sink – which is better, and out of all of them, which is best?

Oh, yeah, and how/where do i fit such things as reactor auto-repair, and there was something else, but i can’t remember what it was.
