LIQTECH 240 High Quality Aluminum Water Block


LIQTECH 240 Patented Shunt-Channel-Technology (SCT)


1. With SCT design, the cold plate can eliminate the "Boundary Layer" to increase coolant flow momentum and accelerate heat transfer performance.

2. When any CPU core is in over clock mode and generates hot spot, SCT design creates the redistribution and remix of coolant flow among individual channels to effectively remove heat surge on the CPU in a extremely timely and efficient manner.

LIQTECH 240 Double-Thick Radiator with Seamless Contact Area


Enermax innovative seamless radiator offers 140% better coverage than a conventional structure.
This makes the fins to carry away more heat from the pipes and cool the coolant efficiently than traditional structures.

LIQTECH 240 Flexible Polyamide (PA) Rubber Tube


The flexible polyamide (PA) rubber tubes with non-permeable layer.
PA tubes are commonly applied in aerospace industry, provide maximum durability and effectively shield against leakage and corrosion.

LIQTECH 240 Patented APS PWM Control


Three Cooling Modes:

*Silent mode: 600 - 1300RPM
*Performance mode: 600 - 2000RPM
*OverClock mode: 600 - 2500RPM

Users can choose the most suitable mode depending on the system application without pushing fan speed up to the limit. Just gently slide the small switch at the fan hub, and an easy adjustment can be made to suit different cooling performance requirements.

5 out of 5 eggsIt's a Freakin Home Run

Go to link above and watch video, it's exactly as he described 100% It's a Freakin Home Run.
Easy installation depending on the case you choose, mounting pump was a breeze hardware worked flawlessly and manual was pretty easy to understand, comes with thermal paste that appears to be working well. I'm glad I took the time and carefully researched before I decided this product is well constructed.
My 4790k with ASROCK Extreme 6 Z97 runs rock solid at 4.7 running prime temps 74-82C fans less than 2000 rpm.
The price was was fantastic at 89.99 free shipping.
I live in Minnesota the shipping temperature was around 15 below zero and the cooler arrived unfrozen, so there must be some kind of antifreeze In this cooler.

Cons: Fan switches are in bad location for easy switching, NZXT 410 case does not have enough room to mount in one piece in top of case, making it very difficult to to install 2 of the center fan mounting screws because the mother board is to close to the fans.
Pump and Fan plugs do not give enough information making it unclear as to where they should go, especially if you have 2 CPU headeaders like my MB 1- 4pin and 1 - 3pin connector? Still not sure.

Other Thoughts: I wish there was more information in the manual about plugging in the pump and fans.

5 out of 5 eggsEnermax Liqtech 240

Pros: Built like a tank
Pump is quiet
Radiator fins don't bend with very high airflow(see other thoughts)
Keeps my Overclocked 6350 under 45c full load
Stiff tubing

Cons: Stiff tubing

Other Thoughts: I have this on my 6350 clocked at 4.5GHz and can't get my temps above 45c with prime95. Build quality is really good. Fins don't bend with my Delta AFB1212GHE-CF00 fans running at 100%.
My only major complaint was the tubing. That tubing made it hard to install in my system but at the same time, I have the peace of mind knowing that they won't break anytime soon.

5 out of 5 eggsThe Specs don't lie

Pros: 1. Radiator fins are really hard... I had no fears bending it during the installation.
2. Pump noise is seriously nonexistent
3. APS fans are great. I prefer the lowest setting to maintain a quiet system. The pressure specs are also very impressive for what the fan rpm are.
4. Brought my CPU idle temp from 32-36C to 25-29C and allowed me to overclock my i7 4790k from 4.5ghz to 4.7 at 1.3V. (I could push this past 4.8 with higher voltage but I would have to set my fans to perform at higher rpms which means louder computer. Something i didn't feel want to sacrifice.
5. The tubes are Flexible polyamide (PA) rubber tubes ensure zero permeability, compared to H100i which has "low" permeability. (take it with a grain of salt)

Cons: 1. I never installed a liquid cooler before so it felt heavy and seemed a bit difficult to install.
2. Following the direction I noticed that it was meant to be a push only configuration (fan exhaust through the radiator fins) which I didn't want. I decided to put my fans on top of my case, then used the long screws to pass through the fans and screw it into the radiator. This works but its not the prettiest thing due to the multicolored fan cables and the round screws exposed above my case. (Fractal Define R4)
3. Back plate instructions were a bit confusing as I installed it as an AMD side first. This is probably user error as I was too excited to install it.
4. Pump light not RGB but its not a big deal considering my computer has gold/white/black/green/blue

Other Thoughts: I initially wanted an AIO cooler to push my i7 4790k since I also got the z97 motherboard. Why buy unlocked components and NOT overclock right?
I watched Jayztwocents review on this cooler on Youtube and seeing as how much he enjoyed it, opt to buy this product. The reason why I got this cooler was for several reasons:
It's not Corsair, (Because everyone uses an H100i and bends their fins.
The fins on the Enermax are stupid durable and Jay wasn't kidding when he said you would need a hammer to bend the fins.
And finally the Pump is virtually silent. I'm pretty sure the only way you can hear the pump is if you put your ear right up next to it.
I'm very happy that Enermax developed this cooler from the ground up instead of using Asetek models.

4 out of 5 eggsawesome minus install

Pros: Well it's a nice system, the waterblock/pump was a pain in the behind to mount onto the cpu. But overall, very quiet, boosted speed by. 2ghz. It is sweet

Cons: Mounting the waterblock/pump. They need a different bracket system because to hold in 4 screws, get the block on and than get nuts started with 2 hands is a pain in the rear.

Other Thoughts: Overall it's a beast

5 out of 5 eggsLOVE IT!!

Pros: Solid! Made of all aluminum including the pump housing.
Super quiet. Keeps my 4790k at 4.5Ghz around 55c under stress test.
Looks beautiful.
Tough! The fins wont bend unless you put lots of pressure to them.

Cons: The sleeving on the fans could've been done better.

Other Thoughts: If someone were to ask me which all in one to try, Id automatically tell them the liqtech 240, without any hesitation!

5 out of 5 eggsOverclocking

Pros: looks great, quality seems high, the fins aren't weak like other radiators, and don't fold over easily, rubber gaskets isolate vibrations. All the parts needed for almost all sockets are included. The fans don't seem loud to me even on overclock settings, they are also well constructed, feel like glass impregnated plastic, may even be a polycarbonate resin, no flash on the mold seams, no splay in the plastic.
It cools. I OC'd my old phenom II X4 940 stock 3.0 to 3.7 and ran full intelburnin test, didn't break 56c.

Cons: the AMD bolts have a flat side on the shaft to lock into the back place, I rounded out the hole in the back plate with finger tightening. Easy replacement, just opened a ticket, had new parts less than a week later, no charges no more questions, good customer service!

Other Thoughts: I would suggest a harder heat treatment on the backplate, or use a carriage bolt design with 4 flat sides, or just put a hex head on the bolt.

5 out of 5 eggsWorks like a charm!

Pros: No software needed (ahem Corsair Link!)
Heatsink on the pump (heavy block)
Rubber fan strips on the radiator
Nice radiator fins

Really love this cooler. I ditched my H80i for it and am very happy. Enermax put a lot of thought into the small details such as braided cables on the pump and the included fans, heavy heatsink on the pump, rubber vibration strips and well built radiator. The radiator has different fins than others I've seen and nice design as well.

It looks great and keeps my 4690k at 21°C on idle. I like the blue light, but some people might not have that color scheme.

Cons: None

Other Thoughts: I installed this in an Antec Lanboy Air case using 2 of the metal brackets from the optical drive bay.

Unfortunately the included fan screws were too short to attach both the Enermax fans and the brackets to my radiator. Tried to find compatible screws from the hardware store, but no luck. I just ended up using my Noiseblocker M12-P fans, which fit just fine.

4 out of 5 eggskeeps it cool

Pros: It does a very good job cooling down the desktop.

Cons: It has a long radiator so if you have a midtower or for that matter any case need to make sure it will actually fit. Also the fan speed control is on the inside of the fans which makes changing the fan speed much more difficult and a pain.

Other Thoughts: There is a few designs flaws but otherwise it does a good job. Just make sure you have a case that is meant this cooling system.

5 out of 5 eggsExcellent Cooler

Pros: Very sturdy design. Easy installation. Good looking unit. I mounted it on the top so you can't really see it. Keeps the CPU cool idle at 26-28 C (and this is a 5960 lightly overclocked to 4.2 GHz). Very impressed with the build quality of the components. Documentation very easy to read. Some have complained of the thermal compound quality. I used stock and had no issues.

Cons: None that I have experienced.

Other Thoughts: I chose this unit because of the radiator design. This is my first water cooling solution and found it very easy with no issues. Another point, be sure it will fit in your case - just some simple research will fix that. A well-planned and thought out installation should give you no problems.
