This we as we continue our AMD Threadripper cooling reviews, we have the Phanteks Glacier C399A waterblock on the test bench. Previously we have reviewed the XSPC Raystorm NEO, the Bykski, and the EK EVO waterblocks for Threadripper. And we have also taken a look at a couple of AIO TR4 coolers from Enermax.

While the Glacier C399A lacks a sexy naming scheme, it is pretty damn sexy when it comes to looks. The C399A is selling for $100 at Newegg. Here is what Phanteks has to say about it.

The Glacier C399a waterblock from Phanteks is custom-designed for the TR4-socket from the ground up. Crafted to push AMD's high-end CPU's (RYZEN Threadripper) to its limit with a massive copper base and fin surface area. The Glacier C399a is made from premium materials, featuring integrated RGB lighting and VITON sealing from the Automotive and Aerospace Industries to deliver the best quality possible from Phanteks.
