The ACM4B is designed to provide the thermal resistance range from 0.59°C/W to 0.39°C/W. Each module uses one(CFR4B) of OLC's world smallest series crossflow fan to achieve linear air velocity above 800ft/min flow through all fins of heatsink. ACM4B series offers "true thermal resistance" to achieve the maximum efficiency of the forced air cooling at lowest profile from 15mm to 30mm.
