How are you checking your temps??? Do you have a temp gun?? If not, I would suggest getting one - they are such an important tool in this hobby.

Also, you may already know but the correct temp range should be 80 cool side 90 hot side.

Some tend to stay on the cool side more often but be sure to check your hot side temps with a temp gun to make sure it is not too hot on that side. Without a temp gun you will not get an accurate reading on the temps.
