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.

Original review below. As of 10/18/19, it's dead; and killed my Threadrupper CPU. ALL of these have a corrosion / scunge problem, and if yours is still working, replace it asap before you have to replace your CPU too. I wasn't so lucky. I just contacted Enermax about it, will update when I get an answer about getting it replaced. I don't expect them to replace the CPU, although it'd be nice.Note that their newer coolers come with a flow indicator, that would have been nice on this one.--The 'Enermax' logo on the pump/heatsink block lights up proportionately to how hard the pump is working, and the fans, assuming your board has PWM speed control, will rev as needed to keep things cool. Using Prime95 to hammer my 8 core Threadripper processor at 100% usage the monitoring software I was using showed that the CPU after an hour of that never got over 58 degrees. After that, it started creeping up a bit, getting to 65 over the next hour, then 70 in the half hour or so after that. Not likely that any game will hit your CPU that hard, though, Prime95 is very much a torture test. I kind of wish I'd gone for the 360mm version, with three fans, but this one is perfectly good for my 20% overclocked Ryzen 1900x.My one real complaint is that instead of a slow, steady pace when they're not working hard, it goes up and down and up and down. At the moment, I have the sides off the new computer (first for testing, never put the sides on until you're sure it works; then because once I copy everything from the old drives to the much larger new one, I want to disconnect the power from them, and now because I've been lazy...) so the noise might be a little more annoying than if it was covered, but when I'm playing a game, they stay steady and are not at all annoying. Would definitely buy it again.

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.

Dopo 3 anni e qualche mese la pompa ha smasso di funzionare. Era quasi un anno che faceva uno strano rumore ed ora non pompa più acqua. Sinceramente speravo sarebbe durato molto di più..Ho provato a smontarla e ho trovato che le alette di raffreddamento in rame interne erano piene di residui di produzione (polveri e pezzettini gelatinosi) che sfavorivano il flusso di liquido. Non sono riuscito ad arrivare alla girante della pompa centrifuga, ma se tanto mi da tanto, anche quella sarà stata intasata da questo sporco e sospetto sia proprio per quello che si sia bloccata del tutto.Infatti nonostante abbia pulito lo sporco tra le alette di rame, la pompa non ha comunque ripreso a funzionare.Di solito nei sistemi idraulici è comune norma prestare attenzione ai residui rimasti nel circuito prima di sigillarlo (sopratutto nei radiatori solitamente). Evidentemente a chi ha fatto questo sistema non importava molto. La fregatura è che i residui (se ci sono) sebbene prima o poi creano problemi, di solito lo fanno dopo molto tempo quando la garanzia è ormai terminata.Nelle foto si può vedere come il lato da dove arriva il fluido fosse in buona parte ostruito da quella polvere mista a pezzetti gelatinosi più grossi.Ricordo di averlo pagato sui 60 euro (prezzo molto economico allora) ma oggi rimpiango di non aver speso qualcosina in più.AGGIORNAMENTO: Oggi per caso vedo un video su YouTube dove parlano proprio degli aio enermax, e pare che non solo siano "famosi" per questo tipo di problemi, ma a leggere i commenti ho scoperto di essere stato anche fortunato che mi sia durato 3 anni circa. Quindi non credo il mio sia stato un caso isolato purtroppo. Per che fosse interessato il video era del canale "gamer nexus", non ricordo il titolo (enermax gunk problem, o qualcosa di simile)

Bei meiner ersten Bestellung war bei beiden Ventilatoren die LED Beleuchtung defekt. Da ich nicht ganzen Kram wieder ausbauen wollte hab ich Enermax kontaktiert und um eine einfache Lösung gebeten, leider ohne Erfolg. Schriftlich hat sich gar keiner gemeldet obwohl es dafür ein Formular auf der Webseite gibt und telefonisch wurde mir mitgeteilt das es nur für Netzteile telefonisch Support gibt.Der Support von Amazon hat mir dann schlussendlich geholfen.Bei der zweiten hat dann alles funktioniert wenn auch kompliziert und dem Gefühl unnötig Zeit verschwendet zu haben.Empfehlen kann ich das Produkt nur wenn alles funktioniert, sollte man Probleme haben steht man im Dunkeln.Edit; bei der zweiten war dann nach ein paar Wochen die Wasserpumpe defekt. Hier hat auch wieder Amazon geholfen und nicht der Hersteller.

Choosing a watercooler is a tough business because there are so many of them and i don't want to confuse anyone further but i couldn't give a glowing review (very much like the wonderful lighting on here)PROSLOOKSYes, it does look wicked (im old school) , i guess folks today would say "it looks sick!" - It is attractive!The colour can be changed to pretty much anything - i use the mystic light app for this and I made sure i used the rainbow connection on my motherboard which is 5 Volts ONLY and meant to be for internal L.E.D. strips according to my manual (MSI Pro Carbon) . Use a more common 12 volt connector and it will blow the light on the cpu pump!! I saw a reviewer online and had done just that. I found that amusing but only because i hadn't done it myself +) That would be annoying to the point of sending it back, I didn’t.COOLINGIT COOLS alright! The cpu at this moment is 51c , I have Ultimate General civil war on pause and a Youtube paused, word doc, amazon, google and various other things open. On boost It will not go over 70c even on high load!THE PUMPNo messing with this out of the box and no bubbles, hardly any audible noise, spare solution should I need it which I doubt. ~Hmm wonder what it tastes like?The CONSFAN NOISE db – as follows45db on top of the pc (the noisiest possible position)43db on the side of the pc41.7db next to the pc (about a foot away next to my desk)35db while writing this review on my sofa (around 4 meters away)Some online reviews suggest it is 30db which I cannot fathom as the cpu wasn’t being stressed - Ryzen 7 & 1080ti .I don’t have figures at full load but its LOUD and not comfortable, I can live with 40 ish db but its not fun at night when I want quiet.Prior to buying I looked up all sorts of charts online to check out noise variants of other water cooled products which only made matters worse and this was not the noisiest by far on paper . However it’s a bloody minefield on youtube and online , just try to google “which is the quietest water cooler” loads of results . Like I said the reviews say it runs around 30db but not my experience im afriad.#The quietist pc build ive made had a NOCTUA NF-P14 which was bliss, big but just soo very quiet it was amazing. but they don’t do water coolers !INSTALLThe Radiator didn’t fit well , I could only line up 1 screw! This worries me – there is enough room for the rad to fit in the case but no way to line up more screws – its meant to have 6 screws fitted.. Again this was very hard to look up on line to establish whether the rad will fit in BUT my case is quite rare - I recommend getting a well known brand of case purely in order to research this . Mine is quite rare but has really lush smoked, reflective glass and 4 RGB case fans included which is the Kolink Observatory mid tower. They sell it on Amazon UK but there are no instructions to download to check that I could find at the time.Other than that it wasn’t too hard to install and I'm glad I bought it. It’s quieter than the RGB cooler that comes with RYZEN 2700x, cools a lot better and is safe (apart from my ruddy radiator).I'm sorry it's such a long interview and I really hope it helps.

Ich verwende die Wakü für einen i9-9900K Prozessor (ist bekannt für recht hohe Temperaturen).Diese sind meiner Meinung nach aber absolut in Ordnung (40-50°) idle/gaming.Anstatt der beiliegenden Wärmeleitpaste habe ich Flüssigmetall WLP verwendet (allerdings ohne die CPU zu köpfen).Die Pumpe ist zwar hörbar aber nicht störend.Optik absolut genial!Bei höherer CPU Auslastung ist die Wakü durchaus hörbar, aber für mich nicht weiter störend.Klare Kaufempfehlung!- Update 6. Mai 2019Leider muss ich meine Bewertung radikal von 5 auf 1 Stern abändern und die Kaufempfehlung zurückziehen (leider auch allgemein für Enermax Lüfter).Ich habe die Wakü jetzt seit ca. 5 Monaten im Einsatz.Nach ca. 3 Wochen hat einer der beiden Lüfter angefangen zu klackern, daraufhin habe ich den Enermax Support kontaktiert. Dieser war sehr kompetent und hat mir innerhalb von ein paar Tagen einen kostenlosen Ersatz geschickt. Erst mal ein dickes Lob an dieser Stelle!Nach weiteren 2 Wochen hat der andere Lüfter angefangen zu klackern... Daraufhin habe ich mir noch mal einige Bewertungen zu der Wakü durchgelesen und auch zu den Enermax Gehäuselüftern (sind im Grunde die selben).Nach sehr kurzer Recherche habe ich gemerkt, dass diese Lüfter bei sehr vielen Leuten nach ein paar Wochen bis Monaten anfangen zu klackern.Also kurzerhand die Lüfter für die Wakü durch höherwertige Silent Wings 3 von be quiet! ersetzt (nebenbei hatte ich dadurch auch direkt bessere Temperaturen).So viel zu den Lüftern, jetzt zur Pumpe:Nach den Problemen mit den Lüftern wurde die Pumpe mit der Zeit etwas lauter und da ich einen möglichst leisen PC möchte stört mich das ziemlich. Vor allem, weil die Pumpe nun seit ca. 4 Tagen noch lauter geworden ist und "seltsame" asynchrone Geräusche von sich gibt, was absolut nervtötend ist.Ich werde das nun reklamieren und mir definitiv eine Wakü von Alphacool holen. Vor allem weil die Radiatoren bei Alphacool immer aus Kupfer sind und nicht aus günstigem Aluminium, wie bei sehr vielen Herstellern.Und es ist mir noch etwas aufgefallen, was anscheinend noch niemandem sonst aufgefallen ist (laut damaliger Recherche):Die RAIJINTEK Orcus RGB Wakü ist 1:1 die selbe wie diese hier von Enermax!Diese hatte ich nämlich davor. Und direkt beim auspacken dieser hier von Enermax ist mir aufgefallen, dass lediglich das Design geändert wurde. Selbst die Pumpe ist an genau der selben Stelle platziert und sieht genau gleich aus, nur das eben ein anderes Logo drauf geklebt wurde.

First off, this was relatively easy to install, just remember if your mobo only has a 12v RGB Connector, USE the included controller, only use the mobo to control the lighting if you have a 5V ARGB connector.The pdf instructions state you can 'lock in' a colour by holding the up button for 3 secs on the controller...you cannot, this doesn't work, at least on mine it doesn't, so if you want just 1 colour, you only have the choice of red/green/or blue.The cooler is quite quiet, cools ok, never had any problems, it looks nice, and it now matches the other 7 fans in my case.
