You mentioned that the pressure is 110 when the system is off. That is about right. That is the pressure at which the the low side and high side equalize at. 110 is fine. Your cooling fan turns on when the system is turned on, which is fine.
If both the low side and high side stay at 125 - 130 then you have a restriction in the line somewhere. Low side should be 30 to 40 psi for good cooling. Most common restriction point is at either the expansion valve or where you have the orifice tube at.
Most common place is at either the expansion valve or where you have the orifice tube at. Both of those tend to get mucked up after a while and cause the system feel warm.
I don't know if your system uses an expansion valve or orifice tube, but this is what I would check first.
So, what I would do is check the expansion valve or orifice tube. If they are mucky or have a any deposits on them replace them. Then, blow out all the lines before switching out the orifice tube or exp valve.
Vacuum down for about 30 min and recharge again.
