Help with raising ambient and cold side temp?

[GiddyGoat]

I have a Che 100 w with a dimmer and it still ran way to hot. I had to take it out completely. I might use it again as the weather gets cooler. I also use a 20l glass tank.

I have a 36x18x18, which is pretty much a 40 Gal. Do you still think 100W will be too much for that?

No 100w should be great for a 40.
