Northern Radiator Fan Shrouds?

Thank you all! I just have trouble at idle at long traffic lights, it is hot in the summer in Texas. Just seems to me that at idle it doesn't have enough air flow coming through the radiator. I installed a160 thermostat and that helped a lot, it still climbs up to 180 or so at a long light, not a big deal I guess. I also have a trans cooler in front of the condenser both affect the air flow.
