LIQMAX 120S 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.

LIQMAX 120S 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 speeds 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.

3 out of 5 eggsWord of warning

Pros: Looks very appealing, blue led on pump is nice. Everything seems good quality, and the variable range switch on the fan is a nice touch.

Cons: The fan can get pretty loud, and the pump is very noisy and doesnt seem to be able to vary speed. I have tried both the cpu fan and the cpu opt fan header on the motherboard, dc and pwm control, and the 3 and 4 pin headers forr the cpu opt fan. None of these configurations allowed me to reduce the speed of the pump to quite it down at all.

Other Thoughts: I have two issues with this. Long story short i was having strange issues with my pc. At first i thought the pump was putting too much pressure on the cpu as the bolt / spring design they have puts alot of pressure on the cpu.

The second issue is that it shorted out my asus z-97 pro motherboard. Enermax sent me some washers to isolate the standoffs from the board and that seemed to solve the issue. So im not sure exactly what the problem was since maybe the added space from the washers relieved enough pressure off the cpu but this cooler was definitely causing a problem.

1 out of 5 eggsShorted out 775 socket board

Pros: Runs stock chip settings at ambient

Cons: Shorted 775 socket board out (Bolts that mount the backplate aren't plastic covered which took forever to figure out why the machine wouldn't post) I just took some rubber and plastic washers and used them and it works.

4 out of 5 eggsFantastic cooler with a pathetically loud pump

Pros: - Cools really great, better than 120M by CM
-The whole product feels well built.
-Installation was one of easiest.
-Fan has built in speed setter.

Cons: -The pump is pathetically loud, I am actually shocked by how loud it is . Lowering RMP to min doesnt do that much to quite it down. On the other hand this means its great pump.

-Fan on there could be better, its decent...

Other Thoughts: - Overall I am impressed. I know this isnt supposed to be a budget cooler like 120V but i got it for 22 dollars after rebate. It performs significantly better than that.

The pump is strong that is why its loud, I just wished it would respond to lower RPM instead of being just about same from 25% to 70%.

Great little unit, if you can deal with the noise ( will be masked by fan anyway when things are heating up) I'd recommend it. Much better than antec's offerings much cheaper than corsair.

- I am using it to cool my g3258 OC to 4.6Ghz @ 1.35V no problem. will report back when I get 4970k in future.

5 out of 5 eggsHappy so far

Pros: I bought this with the intention of buying a processor that I've seen many people say needs liquid cooling for gaming because the Stock Heatsink just sucks, and so far I am very happy with it, I am unsure though if the radiators tubes are supposed to be on the bottom of it or the top, everything I've seen shows them on the bottom, but it won't fit in my case the other way, this is not the manufacturers fault, this is the case manufacturers fault, anyway, I think I may know how to fix the problem, I just need to hope I have the right length of screws to make it work, but yes I love this product, it keeps my CPU much cooler than the stock one, I haven't even needed to turn my other case fans on high since I got it.

Cons: None as of now.

3 out of 5 eggsWorked well for 5 months

Pros: Does its job. Kept cpu at 29-33C idle and never saw it go above 45C at load.

Cons: Hoses are slightly stiff and too short in my opinion. Kind of a pain to install.

Other Thoughts: I bought this back in May and the pump has started this horrible vibrating if it is over the 40% rpm mark tuning software. The higher the RPM the worse the vibration. I can feel it through my desk. I will be trying to RMA... I am sure the pump is failing.

4 out of 5 eggsNice Unit!!!

Pros: Easy install and good cooling

Cons: Standoffs can short motherboard.

Other Thoughts: Install was very simple. Most work is putting on the back plate. What I did was removed my video and sound cards and then removed all the MB screws. Then I just lifted up the end of the MB and slid the back plate under the MB and into it's holes. Then lower the MB back into place and secured it back down. The rest was very easy. I removed the rear 120mm fan that came with the case (Antec 900) then installed the standoff to the back plate. I then attached the 120mm HP fan to the radiator and mounted it where the rear fan was. Then applied thermal paste to cpu and mounted the water block and plugged in the power for the block and fan and was done, or so I thought. Went to fire up the system but it would not post. It just got stuck in a shutdown reboot loop. The most common cause is a short somewhere on the MB. Found that 2 standoffs which are quite large in diameter were shorting a trace when they were tightened down. So I put a nylon washer between the MB and each standoff (did all 4) which did the trick and my computer has been running fine since. I have a QX6800 and running prime 95 cores 0 and 1 don't go above 46C and cores 2 and 3 don't go above 44C!!! That is amazing for a QX6800! Oh and all 4 cores run about 32-33C at idle. Not bad for a basic AIO!
