Our first review of the Enermax LiqTech TR4 cooler was great, and in fact, I highly recommended it as a great option for Threadripper systems. However, shortly before I began this review, some news reached me of premature failures and even leaks, along with an online statement from Enermax.
“We are fully aware of the leaking issue and have stopped selling our 1st gen TR4 cooler as well as the first batch TR4 II. The revised TR4 II coolers have fixed the problem and are arriving to our warehouse bi-weekly by air shipments since early September. We have reserved some units just for RMA so if you are still having problems with the 1st gen Liqtech TR4 or the early production of Liqtech TR4 II, we are more than happy to replace it with the newest version. It can be done by filing an RMA request on our website, https://www.enermaxusa.com/support.php Feel free to PM or reply to this post for any questions. We are here to help :)” – Enermax USA Support Team
Unfortunately, this changes the tone of our review dramatically, as these failures are not something we would normally catch in our review process. We can no longer recommend the first generation LiqTech AIOs, and are leaning that direction with the new variant.
It’s an unfortunate miss for Enermax. The bulk of the hardware is very impressive, even if their claim of 500W thermal dissipation is a bit boisterous on a 240mm AIO cooler. Any time you mix metals in a cooling system, there is a risk of corrosion, and that seems to be what’s going on here. Don’t get me wrong, there are a number of coolers on the market with mixed metals like this, and sometimes, using aluminum radiators winds up hurting the product in the long run.
Thanks for watching the review and teardown of the Enermax LiqTech II 240mm TR4. It’s always fun to disassemble things like this and get a perspective not many get to see. As always, make sure to like this video and subscribe to Modders-Inc on YouTube for the latest in how-tos and hardware reviews.
