Experience: 99 Days


Very compact closed loop liquid cooler. Exhaust heat directly outside the case.
Should come with a second fan. Performance not as high as less expensive air coolers.
This product is meant for people who want a cool and quiet system. Not for overclockers.

Experience: 30 Days


cheap, quiet, water cooler
rad could be bigger
Picked up just cuz it was an amazing deal. Performs as well as any high end air cooler but at a fraction of the cost. Very quiet at idle, and not too bad on load either. Usually i'm not a fan of single rad sealed water cooling systems, but at $30, not a hard decision.

Experience: 2 Months


Self contained system
Factory applied thermal paste is pretty good
Cables on the pump unit and fan are black! (No sleeve, but who cares)
Only one fan
The rad seems a little skinny
No extra hardware included for a second fan
What do I need to say, it works.

I will list some basic temp. benchmarks, but there isn't a whole lot more I can say:
Intel 2500K
Idle: ~30 C
Full load z 4.5GHZ: ~60 C

I think it works very well for the thickness of the rad. That being said, I think the rad could stand to be a bit thicker.

Experience: 8 Months


Great product
Cheap on sale
Used this for 2 different builds, bought it beacuse it was on sale, it is comparable to a corsair H60. Get it!

Experience: 2 Years


inexpensive, quality, quiet.... Go Canada.
a mere step
I have built a lot of water cooling systems, fabricated my own blocks out of moldmax and all kinds of exotic materials. This unit boggles my mind in terms of efficiency. It is great. If you have never watercooled before this unit or other similar sealed units will make you a customer. Most of Google's servers run off water cooling but they are retarded in effiecient because they dont use a system like this. It is a classic case of success blinding the players to the fact that they have solved the wrong problem, anyway. This little unit is awesome Coolit is the premium implimentor. However, if you have custom watercooled before, this thing is upsetting, It is unachievable in the diy in terms of price per thermal drop  but the diy world is 100 times better and funner. Really I think this and similar units puts all air cooling reviews obsolete. after mounting Noctura's in many production cases. I'll take units like this everytime. I give this five and the H-100 four. This unit isn't lower temp but it is way better. Huge value, goodbye Coolit, see you on the server side when the geriatrics catch up. Make it white and call it Icool and maybe the CEO will bust into the IT closet and claim we have to water cool. ha ha ha ha

Experience: 12 Days


Fast and easy install, does a decent job of cooling for intro to liquid cooling, but I wouldnt recommend for the overclocker
I have nothing bad to say about the Eco just simply amazing !
Great cooler, it offers small taste of the potentials of water cooling without all the work and possible risk.

Experience: 9 Days


Keeping my FX-8150 at room temp.

Experience: 1 Days


looks good, too
instructions could be better
some may find the fan a bit loud (but it beats the banshee wail of the stock cooler fan)
Got this unit on sale to replace the stock cooler on my Phenom x4 9750, and what a difference right off the hop! Idling went down from 43-46 to 35, and load while gaming went down from 64-67 to 47-49...and I haven't added a 2nd fan to the radiator yet, these results are for right out of the box. Highly recommended for those (like me) who are on the fence about trying a liquid cooling solution (and the price point doesn't hurt either).

Just make sure to check the fan settings in your BIOS after installing this, to make certain all is well, and disable anything like ASUS Cool n Quiet that may be interfering with maximum fan speed.

Experience: 6 Months


easy to install
No backplate for AMD3
Rad could be bigger
This is a great product have one and I love it

Experience: 2 Months


Liquid cooler. Excellent price, even better on sale! Does a awesome job at what it's supposed to do. Excellent packaging. Very adaptable. Quiet.
Poor instruction manual.
I got this cooler on sale and what a bargain. It is very good at keeping the temperatures down. I average 19C idling and 39C after an hour running OCCT. That's with my CPU overclocked 30% from 2800MHz to 3639MHz. As a note however, I did buy a Coolermaster R4-L2R-20AC 120MM Blue LED Case Fan to install on the radiator in addition to the included fan for a push/pull configuration. This makes the stock cooler MUCH more effective. I cant tell you results with the stock cooler. But for the price of a good 120mm fan, the boost it gives this cooler is much worth it. Google will provide bench results of a single fan VS a push/pull config. It's worth it. It was easy to install, even with bad instructions. Comes with all adapters necessary for most CPU types. FYI! It does not include additional fan screws if you do try the 2 fan install. I am very happy with it so far.
