LIQMAX 120S Reliable FEP Tube


LIQMAX 120S Luminous LED Logo for Power-On Indication


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.

1 out of 5 eggsMy latest Enermax Experience

Pros: None that I can see.

Cons: Difficult to install. Mounting plate is a bear with AMD CPUs

Other Thoughts: I just received my second replacement from Enermax, and they sent me the newest model this time, Liqumax II 120S. It lasted a little more than a week and now it is overheating, so they are sending me a 3rd replacement, 4 units in all. Nobody will accept blame and issue me a refund. I am now out $80 for nothng.

4 out of 5 eggsFairly good, i like it

Pros: Only had it for one day but it seems like a nice cooler, it does what its supposed to. Its a fairly simple install. Should fit
most case's that take 120 . Not as loud as i thought it would be after reading some of the professional reviews.
Everything i needed was included. Fan was barely over 500rpm until i turned it up. I'm a in a P/Pull though to be fair.
On AMD FX9590, MSI990GDA, Rosewill Redbone case i didn't have to take the board out. This unit is going to end
up as a customer build at a customers house so no matter how loud it gets i wont hear it from my living room.

Cons: It took so much pressure to get that thing down all i could think during the process was "My boards gonna break,
My boards gonna break, My boards gonna break" Heatsink was in terrible shape but that's about normal for any new heatsink not just this unit.
I wouldn't use them short case to radiator screws, but maybe that's just me. One of my HS brackets didnt appear
to be cut or filed down completely. It was about 1/16" too long and didnt line up with the CPU bracket and pushed
the heatsink bracket on the other side out when i pushed it on. Took about 30 seconds with my dremmel to fix.
Not at all a deterrent for me. I did need to add a another case fan as i expected. With no big beige & brown air
cooler in there pushing air all over the place the rest of my heatsinks and components got warmer.

Newegg lost the 1 star not the product, i ordered 3 day & expedited order process on sunday night monday morning and it took untill friday night at 750pm for ups to show up with it. --It happens.

Other Thoughts: New heatsink or not, the same old rules apply. Heatsink definitely needs to be lapped first. Was actually pretty bad, i did a test install to check for that first.
But that is a normal chore for any new heatsink installations not just this unit.
So take 10 minutes and do it correctly, worst thing that can happen is it lowers your temps and don't warp pr damage your CPU or board.
For AMD, if your only going to use 1 fan. When you remove your old CPU bracket & plate off the back of the board- KEEP THE SCREWS CLOSE.
You should re-use them to attach the radiator to the back of the case, the screws supplied are way way to short.
I need more than 2/3 turns off a screw to know its tight. My case specs were wrong. SO,-IF you get forced into
a P/Pull install like i did, the stronger fan is the PUSH until you get the correct parts. The pump is only
3 wires on a 4 pin connector,so no speed adjustment on that. Over all i am pretty happy with it. I cant really
give you accurate temperature readings as my dungeon is always about 60f so everything runs cool regardless. I needed
to add an extra case fan to cool everything else off after removing the old CPU and air cooler.

I would recommend this and probably will buy another, if this one lasts.

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.
