HWLabs Nemesis 360 GTS X-Flow 360mm 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 from 72.5% in relative performance adding 0.5 to the awarded performance score.

The Bold Scores are based on performance comparisons of only the slim 360mm Rads. On the second line is the score which is generated against all the 360mm rads from the complete round up.

Push Only Thermal Performance

• 3.0/5 – Slim Only 360mm radiators
  
• 1.5/5 – all 360mm radiators

The Nemesis 360 GTS X-Flow’s Push Only thermal performance was weaker with low fan speeds, and average at best with medium and high speed fans against the other slim rads.

Push/Pull Thermal Performance

• 3.5/5 – Slims Only 360mm radiators
  
• 2.0/5 – all 360mm radiators.

In the Push/Pull comparisons GTS X-Flow performed best (comparatively) with low speed fans and dropped off as the fan speeds were increased.

Overall Thermal Performance

• 3.5/5 – Slims Only 360mm rads.
  
• 2.0/5 – all 360mm rads.

With the exception of one data point (which was re-tested to verify the result) the 360 GTS X-Flow had extremely even results for each rpm rate at all flow rates. This resulted in a good averaged result for the X-Flow version of the GTS and ended up in fourth place overall ~ 6% behind the winning radiators score.

Features & Quality – 4.0/5

The Nemesis 360 GTS X-Flow from HWLabs has an excellent matte black finish. Construction quality is fantastic and has a solid and weighty feel to it and the inclusion of tube protection plates is always a welcome feature.

The end tanks have a unique angled shape which should greatly assist in bleeding air from the loop in a vertical installation. With just 2 ports and no ancillary port either, we feel a little bit deprived after having just finished reviewing the SR2 MP which has 8 ports.

As the name suggests, X-Flow is the key feature of this radiator. The X-Flow coolant flow path means that tubing runs of the loop can be done with much less clutter and may even provide opportunities for hidden tubing depending on the case being used. The X-Flow design does generally mean a performance loss but HWLabs have done a great job with the tuning to keep the performance hit to a minimum.

While being a thin rad at just 30mm thick, the X-Flow end tank and port design does mean the overall length of 411mm is longer than virtually all other 360mm radiators.

Summary – 3.5/5 – Silver Award

The HWLabs Nemesis 360 GTS X-Flow is a slim radiator, which by default means it will never have outstanding thermal performance. When we break down the results and look at the thermal performance of only the slim rads, the GTS X-Flow was an average performer and placed 4th in the overall rankings.

Being super slim it will fit in most places locations that have 3 x 120mm fans spaces side by side, but the extended X-Flow tank at one end does make it slightly longer than other 360mm rads.

The build quality and finish are excellent and the X-Flow design almost makes up to the lack of any alternative ports, additionally the X-Flow design has significantly lowered the restriction level compared to that of the regular 360GTS.

HWLabs have offered the market another option with the Nemesis 360 GTS X-Flow. While it is unlikely to ever be hugely popular, it definitely has its place for those who like to keep tubing to a minimum while managing to retain respectable performance for a 30mm thick radiator.

Overall the Nemesis 360 GTS X-Flow is an excellent slim radiator. While it’s not perfect it would still be our first choice for any build where space constraints meant that a slim rad must be used and this is why it earns a Silver Award.
