HWLabs Nemesis 360 GTS X-Flow 360mm Radiator Review

Welcome to another Extreme Rigs radiator review. This time we’ll be taking a close look at the Nemesis 360 GTS X-Flow from HWLabs which was released back in 2014.

We reviewed the regular Nemesis 360 GTS for the Extreme Rigs Rad Round Up 2015, and we have also featured it’s data in some reviews which are the start of our Slims Only version of the Round Up, but we really wanted to see some comparisons between the “regular” Nemesis GTS and the X-Flow variant, and so the testing commenced.  The X-Flow variant is essentially the same core as the GTS but with input and output ports at the opposite ends of the radiator rather than at the same end.  This can help some builds simplify tube routing.

We’ll show the test results compared to another 5 slim 360mm rads which we have completed testing on, and the occasional comparison to the full suite of 29 360’s that we have tested.

The reviews and data we publish could never be achieved without the continued support of our many sponsors. Even though review comments or test data may not favor them every time, they keep stepping up to the plate so we can pass the info along to you, our loyal readers.

So before we delve in, a well-deserved Thank You to HWLabs for providing the review sample of the Nemesis 360 GTS X-Flow!

What’s in the Box?

The Nemesis 360 GTS X-Flow sample from HWLabs arrived in full retail packaging.

The front of the retail sleeve has the now standard Nemesis design and likewise on the back where we find some technical drawings and list of features.

Just to clarify: when using the supplied mounting hardware there is no risk of causing damage to the radiator.

HWL N GTS XF Lr B&W-9We noted in our unboxing of the regular 360GTS that the inner box design has potential to cause damage to the radiator because of the flaps which were pressing down on the core.  The old box is shown below:

Nemesis 360GTS (26)We are very pleased to see that the packaging has been redesigned since then and the potential cause for damage has been removed from the GTS X-Flow boxing (and other Nemesis models we’ve received recently):

I really like the HWLabs style of boxing as the compartment at one end keeps the provided accessories away from the core. It would be nice to see a bubble wrap sleeve over the rad, but otherwise the GTS X-Flow has great packaging that should ensure safe arrival to the end user.

Extent of Delivery:

• 1 x Nemesis 360 GTS X-Flow Radiator
• 12 x M4 x 28mm screw s for mounting fans.
• 12 x M4 x 5mm screws for attaching the radiator to the case.

Under the flap on the right hand side, we found 2 bags with the supplied mounting hardware:

Note that the 28mm screws are only just long enough to mount fans directly to the radiator. If using a mounting bracket, or placing fans between the chassis and rad, you will need to provide your own M4 screws of suitable length. In most instances M4 x 30 screws will be suitable.

  1. Thank you (again) for doing such a great review. I love these data driven reviews that you guys do.

    I recently bought a Black Ice Nemesis 360 GTS U-Flow and Black Ice Nemesis 240 GTS U-Flow. There are in a single loop together with an EK Supremacy EVO X99 and two EK Titan X waterblocks (the GPUs in parallel). So a fairly medium / high flow restriction loop. I also have a dual D5 pump, but as I am currently in the process of tuning my rig I only have 1 pump running. The Flow rate with one D5 on maximum is absolutely fine. The D5 on maximum is also very quiet, so I am lucky there. When I get both pumps up and running I will be able to run the D5s at maybe 40% power each, I imagine, and get satisfactory flow with this set up.

    Point being: given this setup I am glad that I have the extra performance of the U-Flow compared to the XFlow. As these radiators are super thin, I am less convinced at the usefulness of push/pull. If you have space for push/pull you could have gone for a 60mm thick rad surely. Also the extra length of the XFlow – as you point out – could cause problems.

    Overall I think Hardware Labs radiators are terrific products. Only complaint is the 28mm screw length: I had to buy and then wait for 30mm M4 screws to be delivered to me which held up the whole build.
