The Modultra Conductor heatsink is CNC machined from billet 6061 aluminum for thermal conductivity. The heatsink is then Cerakoted for corrosion resistance. The heatsink does not come in contact with loop coolant so there is no chance of loop contamination. All Modultra heatsinks have a total of 112 convection holes drilled on its 4 sides. This is not a cheap feature to add, however it is one of the reasons for its thermal performance. The Conductor heatsink can be used with any Laing DDC or Laing DDC pump clone. During testing we measured a 17-20 degree pump temperature reduction when used with any acrylic or acetal plastic pump housing. When used with the LOBO brass pump housing we saw a 45 degree C reduction in pump temperatures.
