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

Comment:
I picked this up a couple of months ago and finally put it in my new rig. It was hard to mount the first time, but pulling out my RAM and GPU could have helped... Anyway, it took me a few more mounting attempts to get the temperatures down right. Im running an i7 875k (stock) at 29C, 52C on Prime95 load. Pretty reasonable for a 'faux' water-cooling setup. I remember reading that the i7 870 runs at 40C at idle with the stock cooler... so no complaints. I scrapped off the pre-applied paste and put down some arctic silver for good measure.It's fairly quiet, and not that noticeable when the fan does creep up in the RPM's. Looks great, matches my EVGA FTW 200 and the rest of my black parts inside.My one concern is that more and more higher-end board's are having some resistors being built closer and closer towards the mounting bracket. I know these are extremely close on mine, and I wonder if this cooler/pump sits low enough where it could be in contact and become and issue in the future.

Ok guys here are the numbers.I have a QuadCore Intel Core i7 920, 2785 MHz (21 x 133)Stock but have OC to QuadCore Intel Core i7 920, 4200 MHz (21 x 200). RAM DDR 3 runing at 1600MHzo 8/8/8/24. I was looking for something to replace my Freezer Extreme air cooler. I review many air coolers and the Corsair H50. I was impressed with the design of the H50 but didn't like 2 things. 1) The recommended airflow is to bring air from outside to the inside of the case. That would mean I would have to change the other case fans. 2) I didn't like the look of the mounting hardware. I am sure itâ¬"s ok but the Coolit ECO A.L.C. looked like it would do a better job. So with my old Freezer Extreme and the system OC, I recorded the following with air temperature at 22°C At idle 40°C and full load 85°CWith the Coolit ECO A.L.C. in a push pull config. Second fan is a Antec Tricool Blue LED fan running at ~2000rpm and with air temperature at 22°C At idle 34°C and full load 69°C.Note I lower the RPM on the second fan to 1300 and there was a 2°C increase in temperature. My next step is to get a Cooler Master Haf X Full Tower EATX Case and mount the rad at the top to see if it improves air flow. Please note that my windows 7 coreparking is turn off so none of my cores are shut down to save power.

If you don't want to spend $300+ on a full water cooling setup this is the perfect solution. I bought this many weeks ago and installed it on my overclocked Q9550 c 4.0 GHZ with 1.360 vcore. LinX temps max out at 75C in realtemp with ambient of 22C so that is really good considering how much more power it pulls in LinX versus Prime95 or an actual application or game.The base of the copper is slightly convex so it will work well with chips with one silicon core in the middle such as a Core 2 Duo or i7 (regardless of how many cores it has) but with Core 2 Quads which are basically 2 dual core silicon cores they are spaced roughly 4-5mm apart from eachother so heat is not generated exactly from the center but rather from half way between the center of the IHS and the side of the IHS on both sides. Regardless, it still cools the chip well. I might lap it to see if it a makes a difference. Overall, a good buy.

Ok first of all despite the fact Cool IT states installation is easy its not. Yeah steps 1,2,3 are straigthforward but very vague, especially the part regarding screwing it in its place. When you attach it to the CPU use a screwdriver not hands! You need to rotate until screws reach the middle otherwise it wont work proplerly.Using PRIME 95 CPU reaches 80C in 5 minutes but good thing is it stays there. On idle I get approx 50-55 which is OKTook some time to install ( reinstalled two times)p.s. Maybe its just me but I think instruction should be more clear precise

I have an amd 965 black edition overclocked to 3.8Ghz (stock 3.4Ghz). With the stock cooler it was 44 C idle, 64 C full load. With the Coolit ECO installed it is 30 C idle, 48 C full load which is awesome! Sturdy product and extremely quiet.

As I said it leave a very small footprint,so it can go in any case.its efficient,and looks very nice.Very silent.Does exactly as advertise.

The reason I brought this product is to replace my old ZALMAN CNPS 9500 AM2 heatsink and use it on my other computer, and the price are quite cheap for a watercooler, so if your looking for a great cooling fan or watercooler that will dramatically drop  the temp of your cpu then this is not the heatsink for you!! if just 3 or 4c that your concern about/would like to try water cooling on cpu, then this is the product for you!!

I got this to replace my stock intel HSF on my i7 930, that was too noisy and and "stock" performance.I haven't OC'ed yet, but the stock and load temps dropped between 5 - 10 degrees. Performance is good.Word of warning, do not over-tighten the screws. When I used a screwdriver and really tightened it down, my motherboard would not recognize all 6GB of my RAM (it only saw 4GB). It saw all 6GB with my stock HSF. I loosened the retaining bolts a bit and viola, the 6GB were back.This and the fact that it was a little finicky to thread the retaining bolts is why I don't give it 5 stars.Coolit should add backplate retaining nuts to their design inbetween the back plate and the heatsink, instead of relying on double sided tape to keep the backplate on, and dexterous fingers to get the bolts to thread without damaging the motherboard.

Great cpu cooler kit. works alot better than my old giant metal heatsink that was way to big and impossible to install.keeps my stock amd phenom II x4 940 at 37c idle - 53c playing bc2 using the provided TIM. not needing high rpm fan has also dropped noises level, the pump is whisper quiet.Installation while tricky (installing the rad/fan then cpu block) is a lot easier than my previous air heatsink.On the Fractal Design R2 case I had to remove one of back top fans (140mm) for the radiator to fit.(120mm might but I never tried)Great product, can't wait for the next.

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
