Also if you dont mind burning spare coolant cells this design:
might be for you it will burn 4 of the coolant cells away each cycle in return for little required cooldown time after each (as long as you replace them)
good if you have spare tin and an extractor but want less hassle
After 2000 ticks those 4 coolants get destroyed, and there are 2 cells on the side that have 4000 heat in them. You'll have to wait, or let them cool down. So you generate energy for 2000 ticks, and cool down for at least 4000 ticks. (50*2000 / 6000) = 16 EU/t, of course you could always just remove those overburdened coolant cells and make new ones.
The OP seemed to want to just leave it there and run, how ever, and your design is a Mark IV (About 20% of a full cycle,) meaning it will need to be maintained at least once, because there are broken components. As soon as those 4 cells are destroyed, massive heat is fed through the system.
