Watercool is one of the smaller companies in this hobby of PC DIY watercooling, however no one can deny they have a certain craftmanship that helps elevate their products in the eyes of many people. In particular, the Heatkiller IV Pro CPU block proved to be a big success (relatively anyway in scale) and their GPU blocks are also selling extremely well this year- more on this soon. With a slow revamp/upgrade of all their products ongoing, today we get to take a look at their new reservoirs. It is 2016, so borosilicate glass and built-in lighting support seems to be a must have in high end reservoirs and the Heatkiller Tube promises all this and more. Thanks to Jacob, we get to examine one in more detail.

Let’s begin by taking a look at the specs from the product page:

I requested the 200 D5 version in the default black color configuration, and by this I mean getting the reservoir with a 200 mm long tube with an integrated D5 top to also test for Watercool’s D5 top performance. This is a fully modular reservoir in that all parts are removable and Watercool has individual parts to swap out- a different length of the borosilicate glass tube perhaps? Check out the dimensions of the reservoir as a whole- this thing is MASSIVE, and weighs a lot too. But to be honest, with items such as reservoirs it is best to talk with pictures as well so let’s go along now to the next page for an unboxing and overview.
