HWLabs Nemesis 140 GTS Radiator Review

Thermal Performance

Thermal Performance scores are derived from the relevant Performance Factor scores. We set this scale with 72.5% and below as the 0 mark, with each 2.5% increase in relative performance adding 0.5 to the awarded performance score.

Push Only Thermal Performance

•  2.5/5
  

The Nemesis 140 GTS’ Push Only APF result of 87.4% translated into a thermal performance score of 2.5/5. It’s thin core core produced good results at all fan speeds in Push Only but it’s high 17 FPI count meant it was not quite as efficient at low rpms. It was the weakest performer of the test group but it was also the thinnest.  So do not be put off by the ranking if you are considering this radiator, particularly if you are in the market for a slim 140mm radiator.

Push/Pull Thermal Performance

• 2/5
  

The Push/Pull Performance results were dominated by the Nemesis 140 GTX which is the GTS’ bigger brother. Taking into consideration the thickness of the competition the GTS still had a good score.  Besides we feel that a push/pull set up is not best suited for the Nemesis 140 GTS, or any other slim radiator.

Overall Thermal Performance

• 3/5
  

The Master Performance score of 85.6 generates a respectable overall performance score of 3/5.  This is a good result given how dominant the winning radiator was. The competition tested here had much more cooling potential because of the extra thickness of their cores.

Features & Quality – 4/5

Like all HWLabs radiators, the Nemesis 140 GTS has excellent packaging, but is lacking bubble wrap protection that we wish they had. Screws are provided for installation and mounting of a single 25mm thick fan in certain scenarios. The screw lengths do restrict the installation options without the end user purchasing additional screws.

The build quality of the Nemesis 140 GTS is excellent as is the Black Carbon finish of the review sample. There are only two primary ports and there is no auxillary bleeder/fill port fitted. Tube protection plates are included to protect the core, which on our sample had a reasonably high 17 FPI.  Given this, some dedicated cleaning time should be set aside to keep performance at peak levels. The GTS has a high restriction level for a small radiator.  Consideration of pump power and expected flow rate is advised.  This is especially true if considering using multiple Nemesis GTS series radiators in a loop.

Summary – Silver Award 3.5/5

The Nemesis 140 GTS proved to be a good all round thermal performer although we believe it is best suited for a Push Only fan installation. It was most efficient in Push Only at 1300 RPM. The build quality is excellent, as was the Black Carbon finish on the review sample. It has just the one set of ports and there is no auxiliary port fitted.

At just 30mm thick the Nemesis 140 GTS can be defined as a slim or “stealth” radiator”. The slimness is perhaps the most important feature of this radiator as it can fit into places where the competition cannot.  This makes it particularly useful for auxiliary cooling capacity such as a floor mounted intake or as the primary cooler in a low power SFF build.

So while the comparative thermal performance results may be weak (in a somewhat unfair comparison) and it lacks some features of other radiators tested, we would still highly recommend the Nemesis 140 GTS.
