It's gotten a little hotter here lately. Actually got up to 90F one day with about 90% humidity ( the Humidity is what matters with AC). & my Custom Shroud & 16" ebay electric fan cools it fine. Even had to sit still for a funeral procession for almost 1/2 hr with the A/C on. The biggest thing is the shroud. Mine is not your run of the mill shroud you buy from JEGS. & the switch I use to turn it on comes on at 210 & goes off at 195. So if you have good airflow on the freeway the fan isn't on. If you have the wrong temp switch & it is on when you are going down the freeway it will slow the airflow through the radiator, causing a loss of cooling. If your cooling system is working properly when going down the freeway with good air flow it shouldn't get up above 195F. So no fan should be needed. Seriously, In my professional opinion If you can't get an electric fan to cool your VX, you are missing something. If a Mechanical (fan clutch) can cool the vehicle. A properly designed electric fan setup can also. An aftermarket state of the art radiator can help, but it seems to me. if you want to loose the direct connection (fan clutch) you need to get a shroud like mine custom made for the vehicle.
