ENERMAX LIQTECH TR4 280 AIO Liquid CPU Cooler Review

ENERMAX has been the most aggressive company when it comes to cooling AMD's Threadripper CPU with an easy to use and affordable All-In-One system. Today we are reviewing its THIRD socket TR4-specific AIO. It's previous offerings have been extremely solid and we think that Enermax has stayed on point.


ENERMAX LIQTECH TR4 Assembly & Installation

Fan Assembly

On the assembly side of things, all the user needs to do is install the fans to his liking. Fan installation is the only true issue I had with the LiqTech hardware previously. As mentioned on page 1, fan installation was a breeze this time. Last year we found that the holes were not properly spaced and the vibration dampening material got caught in the threads. Enermax has addressed both these issues and getting our fans attached did not require manhandling the screwdriver.

Enermax includes two pigtails for your fans and connecting those to the motherboard power, or directly to your PSU via a Molex connector. The daisy chain connector for the fans worked out well and is well constructed using wrap as well as shrinkwrap. The Molex adapter is sort of cheap in that it is simply a very fragile run of two-strand wire. Given these are PWM controlled fans, you will likely want to plug these fans into your motherboard anyway. We will touch more on that later in the review.

Retention Hardware

The bracket that locates and fixes the waterblock and pump combo down onto our Threadripper simply slides into a slot around the base of the block. There is a small detent pin that you will feel as you insert the bracket, simply push with a little force and it snaps into place, should you wish to remove it. Remember that the Threadripper mounting points are asymmetric so you can only attach the bracket in one position. If you flip the bracket over, it allows you to reposition your block's tubes at either end of the TR4 socket. This gives you a bit of flexibility in how you want to route the tubing to be in the smoothes possible configuration.

The mounting system on the Liqtech pump/waterblock combination is simple, sturdy, and easy to work with. We have four hold-down posts that screw into the TR4 socket. These have large knurled knobs that allow you to do this by hand.

For actually mounting the block you will need a phillips head screwdriver to tighten down the spring assemblies. These will only screw down so far before running out of threads so it is "impossible" to overtighten the block hold-downs.

The Liqtech waterblock leaves plenty of room for populating all of the DIMM slots on our ASUS ROG STRIX X399-E GAMING motherboard (On sale this week for $321 after $35 MIR!!!). Our eagle-eyed readers will notice that the block is mounted with the protective plastic covering still on. Rest assured we did remove this for testing.

Radiator Mounting

As mentioned earlier, and worth mentioning again is that I highly suggest you mount the fans to the radiator before you install the radiator into your case (which you would likely do anyway). The tubing on the Liqtech is fairly forgiving and about 14 inches / 35.5 centimeters in length.

Enermax Installation Video

Enermax has been kind enough to put together a video of the full installation procedure, and it is actually quite detailed and done very well.

The overall mounting procedure for the Liqtech could not be much simpler and you likely will not have to break out the instruction manual at all.
