Well, there is hardly any difference in complexity when it comes to mods .. One mod can fire 80 watts .. the other can fire up to 160 watts. The end user has to just press the switch, hardly any complexity in that. But when it comes to TC (Temperature Control), there is definitely some complexity.
Right now, all the complexity spins around the atty (RDA) you have on your hands. Kanger is a dick company, I have always felt that. But looking at that build, it only testifies that they are dickheads
Koi aise coil build karta hai yaar? Talking about Kanger .. They stuffed both the coils in between the posts, far away from airflow holes. You've got to keep them closer to the airflow holes instead. The coils should be stretched out above the airflow holes. No wonder the atty heats up like crazy since the air wont fall directly on the coils. Unless the coils constantly cool down, the heat issues will not be resolved.
For example, put the proc fan away from the processor on a computer and see what happens .. The processor is gonna heat up so much, it will heat up the mobo too. It is that simple, the logic is clear.
