As with the Black Ice Nemesis 480GTX reviewed here, the Nemesis GTS line-up is an evolution of the Black Ice GT Stealth from HardwareLabs. Is this another 30 FPI, stealth radiator that necessitated high speed, noisy fans? Well, thanks to HardwareLabs, we can now take a look and find out for ourselves. I should also thank Performance PCs, EKWB, XSPC, MayhemsAquatuning, and Alphacool for providing the other radiators in the test. Finally, a big thanks to Blacknoise Technologies for providing the fans used in this (and all other radiator) test.

Let’s take a look at the listed information for the radiator (the U-flow model, not the X-Flow one) courtesy of HardwareLabs:


  •  120 mm x 4 fan slim form factor two-pass radiator
  • 518mm x 133mm x 29.6mm (L x W x H)
  • 16 FPI 25 Micron Copper Fins
  • Now optimized for sub-800 rpm ultra-stealth fans
  • Supercruise optimizations for scalable performance with higher speed fans
  • 15% more tubing area in the same Black Ice® GTS 480 form factor
  • Increased internal coolant flow rates
  • Standard G 1/4″ inlet/outlet fittings
  • Standard M4 mounting threads
  • Custom Dark Matter high quality finish
  • Fully ROHS Compliant
  • 100% Made from conflict-free materials
  • Industry standard Black Ice® quality
  • Lifetime warranty against manufacturing defects

Straightaway we see that the Nemesis GTS radiators come in at 16 FPI (fins per inch) as opposed to the 30 FPI in the earlier GT Stealth radiators. The performance chart lists a heat dissipation capacity of 1500W and suggest this for a quad GPU configuration. But as explained in the SR2 review, this may not necessarily be a blanket statement that appeases everyone. As always- what is a “good” component temperature is something you need to decide for yourself.
