Finished Looks
The Valkyrie Vind SL125 certainly stands out once installed with it's all black design with red accents really adding a nice visual flair if that is your preferred color scheme. You also have a choice of top plates for the heatsink, one is more subdued being black with a gold logo while the other shown here is more flamboyant to say the least. Regardless of the route you take, the Vind SL125 will be right at home in any red and black themed build.
Concerning memory and graphics card clearance, the Valkyrie offering has perfect clearance for both.
Concerning ARGB lighting, its very subtle, however anything other than red will likely clash with the coolers color scheme, most of the other colors don't fit all that well. That said, I should also mention that bright spots are obvious due to the design but become less noticeable if you opt for a slightly lower brightness.
