The WEP capacitor is a cooling system
The cooling system is your power plant, not your wep capacitor. Heat is on the left side of the UI, not the right.
No, 777Driver is right. The WEP capacitor actually reflects cooling. When there is no "charge" left in the capacitor, look at what it says when you try to fire - in place of ammo, it says "overheat." This suggests that dropping a heatsink might enable you to fire again.
WEP, like the other 2, provide power to their designated system. More PIPs into WEP provides faster recharge of the capacitor ( This is probably why people confuse it with cooling..since the recharge works continuously, and not only when you are not firing a weapon ). As far as testing has gone..its the only one of the 3 that is only used for power charge and doesn't have a secondary effect ( damage reduction for shields / ship speed for engines ).
You can "technically" say that WEP capacitor functions as a 'cooling' device, like you can say any battery functions as a 'cooling' device; it's part of their primary function to hold and transfer energy with minimal heat buildup. The logistical expression of a capacitor though...is controlling energy flow / storing energy temporarily. For all intent and purpose..a capacitor is just an electrical magazine.
As for ED gameplay mechanics, you can't continue firing a weapon by dropping a heatsink while at 0 capacity. That would be like saying you can power your computer by just dropping dry ice on top of it. Why would you need a power supply at all? Or electrical wiring.
Forget the potato clock....icecubes is the way to go. Ha. ( Jokes )
I also don't remember my UI saying "overheat" when out of capacitor power.
No. Since Horizons, with a fully A-rated Python with 2 large beam turrets, 1 large gimballed beam and 2 medium multicannons, during combat I frequently get "Warning: Temperature critical" and sometimes "Taking heat damage", even when I haven't used any SCB's and there is still energy in the weapons capacitor.
This has nothing to do with WEP or cooling in general provided by system parts. This has to do with changes to how heat is built up with 1.5 / 2.0. All things that generate heat now provide higher quantities of it ( or at the very least, they just changed the values on weapons / scbs. Engines / Boosting "seem" to be unchanged. )
So before, when you could run beam weapons "indefinitely" in a lot of cases...now build up heat a *lot* faster since the patch. However many pips you have into WEP has no effect on that outcome, and I have seen no tests / indications / evidence to suggest that remaining capacitor power has any effect on heat buildup either. Heat is handled by your power supply, and it's heat rating ( oddly enough ). *IF* it has been changed with 1.5 / 2.0, it went undocumented / unnoticed.
Goemon is a moderator, not an FD employee that works on the game / dev ( As far as I reasonably know ), hence his/her title of "Moderator" and nothing more.
It's also of note that in the same vague comment on WEP "cooling" they indicate not knowing how different interdiction modules affect its function. So not exactly a prime example of someone who knows the gist of things.
I wouldn't take what was said as any actual indication of how the WEP mechanic functions or its relationship to heat build up. It's like reading a statement of " ____ is good " as in indication of how something works.
( No offense to Goemon )
