I just recently got this box, it runs kinda warm... could be the RDA though, I am waiting for my dotRDA to come in :-\. What top piece do you guys run with your mod? I just got the all black one,
The higher wattage you run it at the warmer it will get.
And many attys get quite hot especially if you run honkin big coils in them. Much of that hear will transfer down thru the 510 and any top mod contact into the mod.
