When it doesnt have the middle pin it is called a torx screw. When it has the middle pin it is called a security screw (that's what we call them in the shop anyways, oftentimes air flow sensors use these types of screws, another name for them are tamper proof screws). I actually have a bit set that's like torx bits, but with a hole in the middle, made specifically for this. Shouldnt be an issue taking it all apart. I will try to post before and after pics of the system/controller cleanings when the console arrives....
