Make sure the air flow is wide open. You can inhale as fast as you want, the faster you go the cooler the vape will get.
Another thing you can do to cool it down is leave a little gap between your lips and the drip tip so when you inhale you also get a bit of air passing through the gap. Doing this means you don't have to inhale as fast, you can control the total air flow by using a bit more or less gap.
As battery voltage drops the power level will drop and the vape will cool from that.
Try it and see, you can't hurt yourself. And don't worry about the crackling. That is normal with a new, clean head installed. It will subside as you put more juice through it.
Let us know how it goes.
