Possible EWP PWM Controller
The thread on the EWP took a tangential bend about PWM control of the pump to help better handle higher loads and temps....
This product from Spal may well be suitable as well as easily adaptable to improve cooling with a Mezier EWP.

The SPAL FAN-PWM fan controller can be connected to the factory (OEM) temperature sensor or an aftermarket electric guage sensor. This eliminates the need for an additional sensor. (The unit is designed to use the OEM factory type sensor on fuel-injected vehicles. Some older style sensors will not work.)
Controls up to 25 amps of fan current
-The SPAL electric fan controller (FAN-PWM) will Pulse Width Modulate a single electric fan allowing the unit to vary the fan speed based on engine temperature. A second fan can be added with the use of an additional fan relay harness (FRH). The second fan will not be PWM controlled; it will be ON/OFF only.
Utilizes Factory (OEM) sensor or optional SPAL sensor
-Smart software that automatically recognizes the OEM sensors calibration as it is being programmed
-Great for use in modern computer controlled vehicles
-Preset for plug and play application when in use with the optional SPAL sensor (FAN-PWM-TS / Low setting: 160 degrees, High setting: 200 degrees)
-Detailed wiring instructions for single fan/dual fan and vehicles with A/C included.
Air Conditioning Input
-Activates both fans when A/C is turned on

I would definately buy one. I think it would bridge the gap between EWP's and traditional setups.
