I wanted to know if someone could help me out, i was running my aftershock today (without the body) and about 15 minutes into it i went to run a temp check on the cooling head, when i took the temperature at the TOP of the cooling head it was about 180 degrees F when i moved the temp gun down near the bottom of the head it flashed 285 and then i moved it to other spots(also at the bottom) and the temp read about 255-270

I just wanted to know if that high of a temp near the bottom of the cooling head is normal or if i need to make some tuning adjustments. In the owners manual it says it should be running at 200-230 at the top of the cooling head. Just dont want to mess anything up...

Thanks
