Enermax brings to us the first All-in-One coolers that are purpose-built for AMD's Ryzen Threadripper CPUs. We review both the Liqtech TR4 240 and the Liqtech TR4 360 using our overclocked 1950X Threadripper system and compare these to our XSPC RayStorm custom cooling loop. Yes, we are setting the bar high.


Enermax is a well known name among computer enthusiasts. It has been in business since 1990 and is best known for its high quality power supplies. We have been reviewing its PSUs for over 10 years, and it simply builds some of the best PSUs in the business. Like many companies have done over the last decade, Enermax has diversified its product lines far beyond PSUs. We have been reviewing its CPU coolers for 5 years. Recently we have reviewed the Enermax Liqmax II 240 AIO and it took home our Gold Editor's Choice award. So assuredly Enermax does have some pedigree in the AIO arena, albeit short. Today we are focusing on its Liqtech line of CPU liquid coolers.

The Enermax Liqtech TR4 240 and Liqtech TR4 360 are the first AIO CPU coolers that are built specifically for AMD's new Threadripper CPU. That is great, because as of typing this, AIOs built for Threadripper are far and few between. Even at launch we saw coolers paired with Threadripper review kits, that were simply not suitable for those of us wanting to overclock our Threadripper CPUs.

The Liqtech TR4 AIOs we are reviewing today are "identical" in specs (240 / 360) outside of the radiator size and fan count. Our AIOs share copper cold plates, variable speed (500 - 2,300 RPM) twister bearing PWM fans, 3,000 RPM ceramic bearing pumps, and very durable polyamide braided rubber tubing. The 240 model of course has two fans and a 274mm long radiator, and the 360 model has three fans and a 394mm long radiator. These Liqtech AIOs also support Socket SP3 (EPYC CPUs) as well.

In our review today we are going to specifically find out what level of stable overclocking these new Enermax Liqtech AIOs support.

What's in the Box

Both units come in identical packaging outside of the model number. These boxes are actually very large and keep the AIOs very well protected during shipping. The parts of the AIOs are contained inside closed cell foam within. The packaging is extremely well done and protects the unit extremely well.

As mentioned the radiator length is our biggest variable between the two Liqtech models.

The included fans look and feel to be quality built. These all are cushioned on all mounting points to halt sound caused by vibration. And if you want at some point to use your own fans, Enermax has also laid vibrational dampening strips down the entire length of the radiator as well. Enermax installed a trim piece down the length of the radiator in order to give it a better appearance and I think it works, but obviously that is 100% subjective.

Of course the "claim to fame" for these new AIOs is that the coldplate fully covers the Threaripper's Integrated Heat Spreader. The coldplate is mostly flat, but it does curve up a bit towards the edges which you can see a bit in the following pictures of mates. Enermax does also refer to its coldplate having "Patented Shunt-Channel-Technology (SCT)," which pertains to how exactly the coolant flows through the fins on the coldplate. I have seen a more than a few coldplates in my time and honestly there does not seem to be some big secret at work here. Of course the proof will be in the cooling.
