Enermax LIQMAX II 240mm High Performance Intel/AMD Liquid CPU Cooler, ELC-LMR240-BS,Black

Bought this for my 1950X on the good reviews that it got from the press. But nobody took the time to test it longer term to see about the quality of this unit, I'll admit I was a bit worried about the quality for the price and knowing Enermax's AIO reputation for failure. Well, either I am unlucky, or all of that is totally true. I've never had an AIO fail before and I have owned a LOT of them, but this one didn't even last me 2 months.At first it was great, like totally great, I installed it using Arctic MX-4 Thermal Compound because I am sure the included stuff sucks, I then checked my temps and I was in the 35C range on my 1950X, load temps rarely hit 60C even in synthetic loads, all was well. I used Noctua NF-F12's with this to keep it as cool and quiet as possible as the included fans while nice, are a bit loud.Suddenly, about a month and a half later I noticed my idle temps were A LOT hotter than normal, and I mean sure my ambient temps were about 5C hotter, but were talking idle temps of around 62C which was really really odd. Do keep in mind I run a ton of background stuff, so it is normal for my idle temps to be a little hotter than other people's, but nothing like this, those are almost load temps. I then decided to run a stress test to see how things go and it was hitting the 68C thermal limit almost instantly and my 1950X was throttling back down to around 2.8GHz which is horrible, especially considering I generally was always in the 3.7GHz all core boost range when doing most tasks. I was at stock settings for this, and I did overclock previously to 4.1GHhz at 1.35 vcore just for the fun of it and this cooler generally kept me under 80C (still hotter than I would like on a production machine, this is why it was just for fun, but I was definitely impressed with what the cooler could do).I decide to touch the radiator to see if it was warm or not during the stress test, as it should be if it's working right. And to my interest only the first inch of the rad out of the tube inlets was hot, the tubes themselves were also hot, the rest of the rad though was totally room temperature, which is not normal for this cooler as the entire thing used to get hot.So I decided I would take everything apart, install my Noctua NH-U14S TR4 air cooler and see how the temps are then to verify it's not a bad CPU or bad board or something like that. I also speculated my thermal compound application could have been bad, but when taking the block off it was totally fine, not too thick not too thin and it covered the entire IHS. I also noticed when taking this off that the water block/pump unit was super super hot, I mean almost too hot to pick up. I mean I know those can get warm at times, but I have never had an AIO that was this hot to the touch around the block area. What this does mean, however, is that my thermal compound application was fine as the heat was obviously getting into the block. Keep in mind this was like 10 minutes after turning off the machine and it was still this hot.Finally, to the "final" part of this long review, my Noctua NH-U14S is installed again and idle temps are around 42C sometimes a bit lower depending on ambient. I know this is higher than most people with the 1950X but I am in a fairly warm room, with lots of background stuff running so idle isn't really idle for me, and I am in a really hot case with low airflow, the Phanteks Enthoo Evolv ATX TG with dual 1080tis so things get pretty warm, plus my Noctua NF-A15 fans dont' cover the entire heatsink since my RAM is so tall. Now for a stress test, under load I am hitting around 65C for the most part, could maybe be lower with some fan curve tuning. If I stress the GPUs and the 1950X both with synthetic loads I can produce enough heat to hit thermal throttle on the 1950X (66C is throttle but only by the boost clock, 68C will throttle a little harder but not much) sometimes hitting 3.3 or 3.2Ghz momentarily. But this isn't a workload any desktop would normally see, and of course I could crank the fan speeds up and avoid this but I like things as quiet as possible.All in all, one star, I don't recommend this cooler to anyone, or any of Enermax's stuff anyway. And I do not recommend using this on a production machine that cannot afford to be down for a given period of time. If it's just your gaming machine that you have (idk why you are using a 1950X for a gaming only machine, but I digress) then it would be fine. Oh and I am sure I am going to get contacted by the "customer support" on here about replacing it. Thing is, I don't think I even want a replacement, I have no use for it now and probably just want my money back.

I installed this for my recent build for Ryzen 1950. Of course it works perfect and the CPU always runs really cool. My case fans don't come on that much which tells me that this water cooler is doing a really good job, and I do play a few graphic intensive games. It was a breeze to install, other than I had to drill a couple holes in my case since the holes didn't quite line up perfectly, but no fault to the cooler. My case is the monster size Cosmos II, and this cooler fit pretty tight inside-top, but it did fit like a glove. Of course check your case dimensions prior to purchasing this. Highly recommended for anyone with a Ryzen Threadripper, that wants water-cooling and complete coverage of the CPU, while keeping it simple and inexpensive.UPDATE: Well, today is 6/26/19 and the pump and the cooler has failed. So, it lasted about 1.25 years. It worked good while it lasted. My machine kept shutting down for no apparent reason and would not boot back up or POST. I noticed that the top of the pump was rather warm and the sides of it were hot to the touch. That's when I suspected inadequate cooling to the CPU. This was my first ever CPU water cooling. Today I replaced the Enermax water cooler with a Fryzen fan cooler. Back up and running at a very cool 37°C, which is about what I was getting from the Enermax when it was new and in top working order. I think I'm going to stick to fan cooled unless absolutely necessary to go water. I don't particularly like the noise of a fan running all the time but at least my machine is up and running and no worries of a pump failure. Much better reliability with a fan. If/when I go back to water cooling, it will be a custom built loop and not one of the AIO coolers.

Purchased this product to cool the 1950x as recommended by numerous youtube personalities. My initial idle temps were 50C and full load at 70C which was surprising. After a year of gaming and work load I noticed the idle temp creeping up to 60C with high temps hitting 80C. The high temps affected performance in both gaming and work so I decided to remove the block to see if the thermal paste was the issue. After removing the block I noticed burn marks in the copper around the edges. I also noticed a smell emanating from these spots which was concerning. After removing the thermal paste I didn't see any issues so I reapplied thermal paste and tried to test idle and high temps. It now sits at 55C idle and 75C underload. Not entirely sure why I keep experiencing these high temps and youtube videos seems to confirm my installation is correct. Considering moving to a different product since the burns on the copper block are a concern.**UPDATE**I watched the Gamer Nexus video on how faulty this product is. It is a product wide issue for version 1 where there are dissimilar metals, poor liquid and degraded rubber gaskets that clog the pump from operating. After the 12 month of continual operation I was noticing a slowly climbing idle temp from 34C from date of install to 58C at the first week of October. I was outside of Amazon Warranty and I didn't realize I was outside of Enermax's warranty. I took a chance and RMA'ed the product to see if they would honor the expired warranty noting the similar symptoms I had from Gamer Nexus' investigation. After providing the necessary information (do not dismantle this product) I was able to get the RMA approved. Enermax will be shipping me the version 2 of their liqtech product but I have concerns since that product seems to be having issues.
