The Black Ice GT Extreme was one of the highest performing radiators for the PC DIY enthusiast- not something easy to improve upon. But the consistent evolution of design from Hardware Labs has led to what I believe is the most impressive radiator line-up currently available. Now allow me to explain why I think so, and hopefully you will leave just as impressed by the time you are done reading this review of the Nemesis 480GTX. I must thank HardwareLabs for this sample, and also 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 courtesy of HardwareLabs:


  • 120 mm x 4 fan Xtreme form factor two-pass radiator
  • 518mm x 133mm x 54mm (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® GTX 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

The performance chart lists a heat dissipation capacity of 2200W 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.
