Live OR Die,
I couldn't agree more, with your post. I've been using my Coolit ECO for a month now and it so far meets or exceeds Coolit systems claims for it. Mine is mounted on an AMD 955BE/C3 in a GigaByte MA790X-UD4P motherboard, in a Cooler Master 534+ Centurion case. I originally used a Freezer 64 Pro from my original build, before the 955 was installed. Summer temperatures in my part of Southern California generally reach 110F/43C and higher, and the house I live in is post WW II, with no insulation in the walls at all. My room has SW exposure, so the heat starts in the early morning and continues to have direct sunlight until late afternoon, so it's a difficult room to cool. It takes a 9000 BTU window unit to maintain a room temperature in the low 80s. I know that sounds high, but it is dry here, so it is quite comfortable.
My 955 is overclocked to 3.9GHz, and I have no problem maintaining idle temps in the high 20Cs to the low 30Cs. Fully stressed with Prime95, 4 cores, I have yet to exceed 48C, although that may change as the summer get's hotter. I still don't expect it to crack 50C. Here's my temps at an ambient temp of 80F/23C.
Here's the temps fully stressed with Prime95, 4 cores.
Despite being fully stressed, I find the heatsink/pump, lines, and outsides of the radiator remain cool to the touch. I've tried many combination's of fans, and so far the best yet is a Scythe Slipstream 1200 rpm, 68 cfm fan pulling air out of the back of the radiator, with the stock 1800 rpm, 63 cfm fan pushing air into the front of the radiator, running at full speed.
Scythe SY1225SL12M 120mm "Slipstream" Case Fan
Surprisingly quiet, and it does cool very well. Louder than the stock single fan, but not annoying at all. The only problem I did encounter was high motherboard temps, caused by not enough airflow over the NorthBridge chip. Here the ECO pump was a blessing in disguise. I removed the 70mm fan from a Propus 630 stock cooler, and slipped it in between the pump housing and the plastic thumb screws. It fits snug enough without having to mount it, but I will be adding a long Zip Tie to go around the mount and the outside of the fan, just to be sure the fan doesn't move. The 70mm fan blows air right at the back of the video card, and does an excellent job of cooling the chipset and VRM's at the back of the motherboard. It dropped the motherboard temp from 53C to 36-37C running at 3200 rpm, and is extremely quiet doing it. The only complaint I have with it is the packaging. Mine arrived with some slight bending of the fins in a couple of places on the radiator, which I fixed with a small hemostat. Coolit needs to find a better way to protect the fins during shipping.
To those that complain about the stiffness of the tubings, be aware that what you call the tubing's is actually the protective housing for the tubing's. The lines are inside them, and are 1/8" ID. using a little common sense when moving them around, and the swivel connectors on the pump, no one should have any difficulty in installing one. Don't be afraid of it, you won't hurt the tubings bending them. Check out this video, and you will see what I mean.

The guy in the video whips the rad and fan around by the pump. While I wouldn't do that myself, I do know someone on another Forum that actually did it with his, before he installed it. No leaks or ill effects at all! The one thing it does better than any air cooler is there is no hot air blowing around inside the case. The heat is effectively "exiled" to the rad, where the fans efficiently remove it. When I stress test it at 47C, the instant I stop the stress testing, the temp drops from 47C to 36C, in a fraction of a second. If you blink you will miss it! It's an excellent product that's well made, tough as nails, and performs as advertised. Used in a case like mine, which isn't wide enough to install a V-10, TRU 120, or any other tall air cooler, without removing the side fans, it's a blessing!
