Here's our tear-down video. More info in text below, though the tear-down process and components are also shown in the video.
The Cooler Master CLC uses a different design than what we commonly find, seeing as both EVGA and Corsair/MSI use Asetek-designed coolers. CM's pump block is larger, uses a wide copper plate that connects directly with the VRAM plate (custom design), and then uses a protruded and isolated copper coldplate for direct GPU cooling. Isolating the protrusion assists in lowering GPU temperatures measured by the diode. This is a challenge that EVGA faced with its VRAM cooling plate, as the shared usage of a CLC will increase the measured GPU diode temperature due to saturation of the cooling solution.
We believe the barb closest to the right-side VRAM is the out valve, as this would be the hottest location on the solution (closest to VRAM & VRM). The VRM is sinked by a copper plate and thermal pads, including the inductors, and transfers its heat to a small copper heatpipe. That heatpipe connects to the right-side VRAM plate, which connects to the CLC coldplate directly.
After testing – which will soon be published in the review – we believe that the Cooler Master block is running a higher RPM pump and may be doing some strategic liquid routing to improve GPU temperatures. Unfortunately, because this card is loaned by a reader/viewer (thanks, Sean), we can't take apart the Cooler Master CLC for further analysis.
GTX 1080 Xtreme Water Force PCB photos are enclosed as well, but we'll forge ahead with a separate PCB analysis for more on that.
More content on this card in the coming days.
