WebCooling a CCD/CMOS sensor largely reduces the dark current. However, the effects of dark current are purely a function of exposure time, so it only really helps with long exposures. High-ISO exposure noise is as much or more of a function of the CCD/CMOS sensor read noise then the dark-current noise of the sensor.
