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 eggsNice Cooler

Pros: Solid build quality, fan speed switch built in.

Cons: Benchmarks say its 1 or 2 degrees warmer than some of its competitors. I don't care the build quality is that much better! Way better! Seriously! The only thing I didn't like was the oddly stiff and greasy thermal paste, still worked fine. Why should I complain? Liquid cooling units often don't even come with paste so thanks Enermax. The Liqtech name is creepy there found something bad.

Other Thoughts: Best Build Quality!

4 out of 5 eggsMuch better than the Corsair

Pros: Solid build. All hardware included. Easy to install. Quiet. I like the pump bracket, very solid, just put on the CPU, tight down the four screws evenly, all the way down, no guess work that how far, how tight the screws should be tighten. There are thin rubber strips run along the length of the radiator, where fans are mounted. This will reduce the vibration from the running fans. Thanks to a well-thought design.
Previously, I bought a similar cooler, similar price range, made by Corsair. The fans are so noisy. I have to ditch them and replaced with Cougar fan, cost me additional $35.

Cons: Can't think of any.

Other Thoughts: Many, many times I remind myself that never pay attention to the rebate. I told myself "If you can afford the item without the rebate, buy it. Do not count the rebate into the final price." So, I bought the cooler without counting on the rebate. Yet, silly me sit down, go online, register the rebate, print out the form, cut the bar code, pack into the envelope, stamp it, and send out. I dropped the rebate envelope in a mail box along with this year CA tax returns (myself and my wife). After two weeks, I got the state tax refund. While the rebate document has not received by the company that processes the rebate. Silly me or USPS? Rebate document always has a better chance to be lost in the mail, more than any important document that we dropped in the mail box. It's a big mystery to me. Probably this is my last opportunity to become a wise person: never count on the rebate and don't bother to waste my time. If I can not afford the item without the rebate, don't buy it.

5 out of 5 eggsEnermax Liqtech 240 is excellent.

Pros: High quality is found throughout. It mounts perfectly at the top of my Nanoxia Deep Silence 1.

Cons: I had to take it to my machinist neighbor to get the screws loose to switch from Intel to AMD. (Not enough to take an egg.)

Other Thoughts: I am doing my initial burn-in with no overclocking of the FX-9590, so temps are fine. If anything goes awry when I overclock, I'll come back to let you know.

5 out of 5 eggsRugged Cooler

Pros: When you take it out of the box YOU know it will do the trick! Nice box and nicer cooler! With or without rebate as good as the rest of the best but more rugged and refined than any other! 3770k @ 4.6Mhz running at 30-31C! PRICE POINT CAN'T BE BEAT!!

Cons: Blue LED on pump w/red sys. Made it work for what it was!

5 out of 5 eggsGreat AIO Water cooler for My Rig

Pros: This thing is built to last a long time. I was able to fit this in my Corsair 450D case with no problems on the top part of the case. This All in one cooler is keeping my Cpu at a constant 29-31C temperature and my case only has 2 case fans plus the 2 fans on the radiator. I'm extremely happy with this purchase and I'm glad it fits in my 450D case.

Cons: one thing I didn't like is the instructions were a little vague but installation wasn't difficult at all. Also the led on the cpu block only glows blue for anyone that does color themes inside their case. This wasn't an issue for me since I was going with a black and blue theme inside my build.

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
