OCIA.net takes a look at the Zalman Reserator 1 Plus in their latest review. Below is a direct quote from the review:

"Zalman went back and redesigned their water block, designating the new unit the ZM-WB3. While dimensionally it's much shorter and wider, and weighs nearly half as much, as to what changes were made inside the block we can only guess. It has been included in their revamped water cooling kit, and with the addition of the ZM-GWB2 GPU cooler has been rebundled as the Reserator 1 Plus. Does the Plus designation indicate an improvement to cooling performance, or merely an excuse to add a few more $$$ onto the cost? Being as this was my first experience with water cooling a PC, I was both anxious and apprehensive to find out."
