AC problems - need help!

[humvee]

Along with the V8 swap, I purchased a new compressor, and new AC lines.
I retained the old condenser and clutch fan, I also have a Spal fan in front of the radiator.

While cruising around 30-50mph, the AC is blowing cold air.
While idle, it becomes warm and unbearable.

I first concluded it was either the old clutch fan, or that I only have 1 small e-fan up in front of the rad.
But after noticing that it also gets warmer while accelerating from a cruising speed of 30mph. And also when cruising at higher speeds. Breakdown below:

Idle: WARM
20-50 mph: Cold
50-70 mph: Less cold
Engine temperature: 105 degrees C


Should it be getting less cool at higher speeds if its just a fan issue?
What do you guys think?

Condenser bad or do you have a leak when you changed everything?

No leaks found, I see water dripping down from the evaporator core area so that seems fine.
Condenser spent 6 months on the garage floor, 3-4 sand storms later I'm sure its built up some debris inside.

I'll take it off and clean it before I try replacing the clutch fan.

Refrigerant may be low. Check the pressures on the low and high side of the compressor.

Did you pull a good vacuum? You may have air and none condensable gas in the system. R134a is cheep,I would reclaim the gas,pull a good vacuum,and charge it again. Put a big fan in front of the truck if it's warm out. You can also run water over the condenser to simulate highway speed.

It could also be over-filled. Reclaim it...pull a vacuum on it...measure the correct amount of refrigerant when you refill it. I've heard too much refrigerant will make it go goofy.
