Overcharging my A/C?

I was thinking back to when I was really into computers. There was a high end form of cooling called phase change - which was basically an air conditioning unit, but the evaporator was a heatsink that was attached to the CPU. With that, one could tweak with how much refrigerant was in the system - slightly less refrigerant would yield a lower 'bottom' temperature at idle, but would have the ability to carry away less heat. Slightly more would mean the idle temperature would be higher, but it would rise less under load. So to get maximum performance meant tweaking with that and dialing it in to find what would yield the lowest temperature under maximum load.

I was wondering if the same thing applied to a car's cooling system? So I could get the system working most effeciently at 100% load?

Edit: I ask not because my air conditioning has a problem. But because the tinkerer in my has been running rampant today lol

Well they have came out with a variable orifice tube. It limits the size at idle opens it at higher rpms. You get up to 12 degrees cooler at idle while still remaining the same temp at higher speeds.
