Both models support the most modern CPU socket types, including LGA1150, LGA2011, AM3+ and FM2+. Users can select the model based on their need.

LIQMAX II features a new cooling block with advanced impellers, ENERMAX patented Shunt Channel Technoloty (S.C.T) and the 2nd generation batwing fans with patented APS (Adjustable Peak Speed) triple RPM range setting function. It also offers the elastic and impermeable rubber tube, the LED logo on the cooling block to indicate power status, pressure adjustment spring screws to ensure a perfect contact force between the cooling block and CPU without damaging the CPU and the highly recommended: Dow Corning TC-5121 thermal conductivity grease.

Such a great product at a great price!!

Pros: Temps on a i5 3570k OC 4.8ghz. Was using a Hyper Evo 212 "Great air cooler btw" and at idle temps 35c and at full oc temps where 78. With the Enermax 240 temps are at 27c idle and full oc temps never exceeded past 67c. Now I also changed out my thermal paste as well from a Artic-MX4 to a Gelid Extreme. Now the main reason I picked Ivybridge is they run EXTREMELY hot!!
That is a -8 differnce on idle and a -11c on the overclock. WOW!! Now either the MX-4 was a bad thermal paste to use on overclocking and the Gelid is magical or the Enermax is on steroids!! Love the sturdiness and materials the 240 rad is made out off, It's a tank for sure. Not a lot of English installing guides on youtube but check out JaysTwoCents and he explains most of what this monster does. The case fans are nice and have some weight to them. They come with 3 preset switches on them.
I paid $69.99 and with a mail in rebate of $20.00 for a total of 49.99...for a $50.00 240 rad!?!?! Even at full price I would still buy it with these numbers. This is a none RGB but does have some lighting but its white so it will go with any build configuration. I highly recommend this RAD at this price ,it's perfect for a Ryzen budget gaming build to keep those temps down since thats the trend right now. It does come with the Ryzen back plate for the Thread-Ripper and AM4 as well. Its pre package for intel straight out of the box. Hope this helps you decide whether or not to purchase this RAD.

Cons: Installing the Block to the cpu is a pain in the rear. You have to hold the back of the motherboard and then with your other hand screw it into the cpu housing. Man I was so mad!!! HAHA.

Other Thoughts: Now I used Gelid as a thermal paste and I recommend heating it up before applying because it's thick. The rad fans have 3 preset switches on them ,low, med and high and I recommend placing the switches so you have easy access to them.
If anything negative happens in the next year I will do a follow up. But for now I give this product 4.8 out of 5 stars....dumb back plate...HAHA

Great performance, PITA installation

Pros: Performs really well. My 2600 doesn't go higher than 55 C on stress tests and I'm really happy with that. Idle is around mid 35 C.

Cons: The installation is a PIA. If you were planning on getting this cooler, I would recommend you install it outside the case. If you don't feel like taking it out, I would enlist the help of your sister, which was what I did. The led on the heatsink is really dim so don't expect it to pop out. The stock fans that come with it are REALLY loud so I would recommend replacing those if you dont have headphones.

Other Thoughts: After the frustrating installation, it was well worth the temps it gives me. If it wasn't for the $20 rebate, I would've skipped this and got a EVGA CLC 240 for another $15 more. Overall, great value AIO for the $45 price

not bad if you get a deal on it

Pros: works awesome for my ryzen cpu . i dont get temps going past 35c at full loard so im happy

Cons: this was difficult as hell to put on a ryzen cpu , the instructions are janky .... its easy for intel users cause it comes right out of the box for intel. but man, you wanna drop kick the thing for amd. super difficult to install amd side, i had to youtube it and it was still frustrating. and dont plug it in your motherboard or you will get overheat issues connect it directly to you power supply

Pump failed after 9 months

Pros: Cheap entry level AIO cooler, runs pretty quiet, easy to install.

Cons: the pump failed inside my system while it was on after only 9 months of use, the RMA staff was helpful and they tested all my parts that were wet from the pump failure.

Other Thoughts: Stay with AIR cooling if you don't want the hassle of sending in your wet parts to get RMA

Nice upgrade from the LIQMAX II 120S

Pros: - Big bang for your buck
- Adjustable Peak Speed fans are awesome
- Enough cooler to run my 3770K @ 5GHz+ no problem

Cons: - Fans are out of +/- 10% spec speeds(+40% on the low end, +17% on the high end)
- Pump is right on the limit of +/- 10% spec speed(almost exactly -10%)

Other Thoughts: I'm not really complaining. Because the product still performs great as a whole(and I still feel it deserves 5 eggs). But I do expect the stated specifications to be reliable. The fans on my LIQMAX II 120s(which are supposed to be exactly the same as these) run between 300-2340 rpm(50%-100%). The fans that came with this cooler run between 700-2340 rpm(50%-100%). All 4 fans are out of spec speeds on the low and high ends. What's annoying is I can't get these fans to run as slow/quiet as the fans from my LIQMAX II 120S(which I'm currently using for a push/pull config on this cooler). 50% is the slowest speed I can set with the fan control software for my motherboard. 50% @ 300 rpm vs. 50% @ 700 rpm is a HUGE difference noise wise(700 rpm is audible, 300 rpm is dead silent). Also...the pump on my LIQMAX II 120S runs @ 2730 rpm(well within specs). The pump on this cooler runs @ 2450 rpm(just barely within specs @ -9.26%). 2430 rpm is exactly -10% of 2700 rpm. Neither pump can be heard running(which is good). But I can't help but think the cooling performance is at least slightly negatively impacted with the slower pump.

Not the best AIO, but will get the job for most users

Pros: It's a 240mm AIO. Throw it on your gaming CPU and you'll be good to go, and even be able to get modest overclocks.
Super easy to install.

Cons: Fans aren't PWM. They are loud and their fin shape causes air to bounce back.
Not the best cooler. My delidded 7700k still stayed in the 60's and low 70's in a room that stays ~66-68Fahrenheit.

Other Thoughts: If you're not planning on trying to push your CPU to 5+Ghz at high voltages, then this cooler is more than enough. It's priced nicely. I do wish it came with better designed fans and were pwm, but oh well. If your PC is a gaming PC, slap this bad boy on it and you'll game smoothly. Can even handle some work loads like streaming.

I did try to do some converting of media files on a delidding 7700k @ 5.1ghz (1.4v) and it did not keep up in terms of cooling. My temps were hitting the high 80's. But assuming you aren't putting intense workloads like that on it, and it's just your gaming pc... this will keep your cpu at a nice comfortable temp.

Been going strong for 3 years

Pros: I have not had any issues with this for 3 years. Was kinda overkill, but kept my AMD Athlon X4 860K generally between 13-42C, depending on room temp and load. Used IC diamond paste for the best effect.

Cons: No way to tell if it should be replace, other than if temps were to start getting higher.
