Coolit Systems Eco CPU Water Cooling System AUTO-REGULATED & Maintenance Free LGA1366/1156/775/AM3

Comment:
Installed onto an aging overclocked LGA775/Q6600 platform as the summer heat was becoming too much for my old Arctic Freezer 7 Pro. Installation is simple but care must be taken to align the screws correctly, it would be very easy to scratch/damage the motherboard otherwise. I removed the preapplied paste immediately and used some Arctic Silver 5. I'm not sure if it makes any difference.Also, on my motherboard layout the power cable for the pump BARELY reached the fan connector it requires; it could really stand to be a few inches longer.I only got this cooler to bring down my load temps, which it does very well. At idle, temps were roughly the same as my Artic Freezer but under load the ECO really shines and gave me 15-18 degree drop  at 100% load! (60 vs 75-78 on a q6600 running prime95 cpu stress)Noise is decently quiet letting the BIOS control the fan through PWM. Turning off this feature will net you a couple of degrees colder but the noise increase is significant.I'm happy with my purchase and reocmmend to people in my situation of replacing the cooler on their aging systems that still have plenty of life left with proper cooling.

In the past I would never consider anything like this. After reading the reviews, I decided to take a chance and give it a go. After the very simple installation, you can see that this looks good in the case. No issues with clearance and everything fits nicely. O/Ced my CPU and have very reasonable temps. This seems to be a great addition, and is sleek and quite.

Replace the stock fan with a Scythe Ultra Kaze 120MM and you will be AMAZED with how well it works, I think it voids the warranty but you should know within a day or two if there is going to be any problems with it (Leaks etc)

Well the first one I got was not good and I RMA'd it. Got the replacement and I am very impressed. These temps are just a little bit better than I expected. I have my 945 OC'd to 3.8Ghz and this is keeping my chip nice and cool. Very happy, would recommend to anyone who is too lazy to build their own loop

Using this on an overclocked AMD Phenom II X4 810 and love it. Piece of cake to install and very quiet.

Easy to install and keeps my computer really cool. I had the H50 before but kept getting inconsistent performance from it, even after reinstalling it. So far the ECO is cooling better and running great. Much less hassle. The pump is silent too.

This is my second CPU only watercooling loop. First one was a swiftech H20-120. This unit is easier to use and cools better (it is a little better than a OCZ Vendette II). The only issue I had was during installation the mounting screws were hard to line up with the mounting holes. The screws stick out and they will scratch your motherboard if you are not carefull. The fan on low is wisper quiet (just as quiet as a noctua) but when at full speed it is audible over the other fans in my case (which is very quiet). If it came with a quieter fan and the screws were recessed during install I would give this 5 stars.

This cooler is awesome! Took a few tries, as it would not initially make contact with my i7 920 CPU on my Gigabyte EX58-UD5 motherboard, but I eventually got it to sit properly. Once I did.... WOW. The chip idles at 36C and doesn't go above 55C at full load. This is in a warmer than usual room, with a pair of GTX 295 video cards running SETIxHome. Simply amazing. I've already installed one on every computer I own, and I will be picking up a few spares to include them in the computers I build for friends.

I was skeptical that such a simple, sealed unit could make a major difference over a decent air cooling solution, but boy was I pleasantly surprised. I dropped about 10 degrees Celsius at idle, but better than that, I can't hear the PC anymore unless I get right down next to it. SO much quieter. It even made a big difference in my vid card (5870) temps. Playing Bad Company 2 (at 1920x1200 all settings maxed), the vid card fan would go to 100% within a few minutes of playing (very loud). Since installing this cooler on the CPU, the vid card fan never exceeds 40% now. Guess not having a giant CPU heatsink right next to the card helps. Even after an hour of playing BC2, my comp is only as loud as it used to be at idle with air cooling. As far as temps go, I idle at about 45-47 degrees C, and under full load it hits about 55 degrees C. In comparison, with air cooling it idled at 57 degrees C, so ya, absolutely great product.

I was somewhat disappointed... so I reinstalled my H50. I found my H50 ran a couple degrees cooler than this unit. But this was my results... and may vary from your results.

I think this is better than H50
