Ok im curious i camt find anywhere on the internet pr threads here so ill make o e to ask. What exactly is a bottom turbine dual coil? I ask because i have been modifying my atlantis since i got it several months ago in a trade improved airflow and rebuildable coils. And i thought well what if i can remake an arctic coil inside the atlantis. But main problem is i dont know what innards look like so to avoid buying a coil head and scraping it i thought id ask here first. I know long shot but hey never know till you try.
