Yes. Heat Pipes are so efficient that they can remove heat from plastic at higher water temperatures. This is due to the fact that the surface of the heat pipe is almost the same temperature of the water. Chilled water is not recommended and, consequently, as a side benefit, eliminates sweating and short thermal shocks. Heat Pipes also have a high thermal mass that cools the plastic in a different manner than water cooling. This provides a plastic part that is more stress-free than a water-cooled part.
Note that for the TPL Series Heat Pipe, tower water that is usually 60-80ºF (15-27ºC) is recommended. The TPH Series Heat Pipe should be used with a water temperature of 90-110ºF (32-43 ºC), typically from a thermolator.
