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

This is a great cooler! I've always had air coolers so when i got this i wasn't sure what to expect but now i'm just happy. got this with the Fractal R3 case combo. keeps my i5 2500k at 4.3ghz at 60 in prime. But the best part is the installation! It was so easy!! hand screws to tighten it, back plate just sticks on, and selecting your socket size takes a couple of seconds.. very well designed!. For no noise at all at full rpm's tho you might want to switch the rad fan to a noctura fan, but the one it comes with is pretty good.

Got this for my 1090t which is clocked at 4.2ghz atm and WOW! stock heatsink would keep the cpu around 55c idle and 85c+ gaming. With this guy here I get ~35c idle and 50c while gaming or rendering. It is a bit loud but i think its the pump and not the fan... but i could be wrong. Installation was a pain in the ass the first time because i tried to get it into an old p4 case on my pentium 4and the mATX mobo gave me a very hard time installing it, specially the pump itself. But on the 1090t it was a breeze, took around 1min to screw everything in/on and BAAAM! done.Ive heard that some ppl are having problems with the am3 socket but I've asked all my friends that have this cooler on the phenom 2 x6s and noone has a problem; so ignore those intel fanboy's rumors

I was buying an MSI 790FX-GD70 / CPU bundle ~10 days ago now and upon adding it to my cart, NCIX prompted me that this Coolit ECO was a 'Surprise sale!' or something to that effect.. for another ~$70..I was aiming to make this box as quiet as I can, easily, so thought Id give it a try.While my memory is still backordered, I started putting this all together the other night and immediately had problems getting the Coolit cpu block to mount..The screws simply arent long enough to go through the motherboard and meet the nuts on the backplate.. I googled for info and on Coolits support forums I find several other people with the same issues.. as far back as at least 9+ months ago..Coolits response was basically, "try harder, its the MOBO manufacturers fault for changing the backplate.. but you can make it work"With a fair bit of force and a screwdriver I managed to get all 4 posts screwed into the motherboard.. but then picked up the mobo and looked at it and the board is bending, badly.If they've known of this issue for at least 9 months.. why havent they changed production to include longer screws?Packing it back up and I'll be asking for a refund shortly.. not going to damage my board trying to get this to mount. Not impressed I'll have to suck up shipping costs for a poor design.

Bought this because my new i7 processor was burning up when I was gaming + recording my gameplay at the same time while it was oc'd.The installation was ridiculously simple and easy, the only snag was the backplate but because I have a LANBOY case I just took the backside off and theres an opening in the plate that the mobo is adjusted to for such things I suppose.It is very quiet, I don't hear it at all even when I'm not listening to music/gaming.. the idle temp went from 22-26 degrees to 16-19 degrees, which is a great improvement in my opinion, also when Im pushing its limits it is no longer pushing 70 degrees its down in the 50's now, overall I am very satisfied and impressed.

Glad I purchased this over an air cooler. Didn't want to break the bank on a more expensive, non maintenance free lc setup.

Comment:
I don't play game. using it on my HTPC, so far so good.

Comment:
Installed this no problem. Using this on my P8P67 Pro with 2500k OC'd at 4.5GHz. Runs really quite and keeps my temps at 35 and 65 under load.

Comment:
Keeps my overclocked 1055T 3.3ghz, at temps of 38C while at 100 percent load. Idles in the low 20s.... what more could you ask for for 59.00..... superior to air cooling. No 2 pound air cooler stressing the board.

Comment:
Have this on my new systemvery quiet and effective,keepsmy system idle at 29-32c andunder load 39-43cWorks great...

At first I wasn't sure if buying this would be a good idea. After using it for a month, I'm very impressed. My CPU temperatures are very low (always between 20 to 30 degrees max). It is extremely quite compared to my old Zalman CNPS9500 heatsink. I couldn't believe the difference. I ended up taking off the stock fan & replacing it with a Thermaltake AF0032 w/blue LED. I like it much better & it does a good job cooling as well. I definitely recommend this if you don't want to get into a full blown water cooling system.

I'm impressed with the quality. Looks cool. Saves a lot of space compared to the huge noctua coolers. I have an 1156 i7 875k cpu. Stock settings it runs idle at 32 degrees, load is 50ish. I OC'd to 3.8Ghz & load was pushing near 90 degrees. I do't need a huge oc, so it suits my needs fine.

Comment:
Well I would really recommend this if you don't plan to use a lot of fans. I don't know how this compares to the corsair but I read that this is really good too.

I was looking for a cooler for my build that was ultra-quiet without sacrificing cooling ability. I've never used this type of closed-system liquid cooling before, so I was a little skeptical. Plus I was concerned with how loud the pump would be. I'm happy to report that this unit runs virtually silent - I can barely hear the pump with the case opened. I had to touch it to make sure it was working. It keeps my i5 760 (t 3.8Ghz) at 35C at idle and around 55C under load. Couldn't be happier - was exactly what I was hoping for.

Comment:
Out of the box it seems pretty simple. The big problem with all liquid cooling is leaks. Are the sealed joints good? I don't know - the video of the manufacturer swinging one round his head seems impressive at first but it is a short time swinging and then it isn't test for leaks afterward so it 's kind of meaningless.There isn't much documentation either with the unit or on the website. It seems easier to install with the MB out of the box but then if it fails or the cpu does it will be a pain doing a replacement.I can't remember the actual MTBF in hours but it came out to something like 8 months if you run 24/7... pretty short.I guess time will tell. I will up date after running it for some extended time.

Got this on special (and part of what sold me was free shipping for my entire order) and don't regret it. Keeps things nice and cool, can barely hear it. The rad does collect dust, but so does everything else, not a big deal. The stiff tubing made things a little awkward to install, but nothing crazy. Great product.

Comment:
I replaced my passive cooler with the coolit. The install was so easy, I did it in 30 min which includes removing my MB. Very pleased - 4 degrees lower and 50% quieter. Will replace in 3 years just in case after warrenty.

using this on p67 , oc to 4.5 ghz with 2600k40 temp / 55 load prime 2 hours max reach temp 70what better do you need? this is the cheapest best watercooling in town!

Comment:
Price is great for a wanabe water cooling setup, and it cools pretty good too. Idle temps are ok with one fan, but load temps are great. Only thing is the pump... I can here it, but only when the case is open. I'm not sure if this is normal but it might need more breaking in.

Comment:
Install was quite easy! Looks cool, and keep my stock intel Q6600 at about 28 degrees C at full load! Lots of people seem to be getting decent overclock using this. Would have liked to see longer tubing but I understand it't because it doesn't have a hardcore water pump in it! In most builds it would be just fine though. Very solid tubing, and no toping up coolant!!! Zero problems so far... I would definately buy this again!

I love this cooler, keeps my temps extremely cool, 30c idol and 49c load. The radiator was a little big for my case, got in the way of the removable panel but a little bending and it fit anyway, just tight. Overall I will be getting another one for my other PC's.

Bought this to try on my sons I760 gamer build.clocked f4.02ghz easily with 1.28v, this cooler allows cpu to run f34-36 deg idle and a max60deg ffull load intel burn test after 15mins...normal use its great as c stepping and eist are still enabled and so cores clock and volt down .fans ok with fan control enabled, nocturna going in soon.I have it in a single push exhaust setup, with great case airflow.looks pretty cool sitting with Msi military spec labels and msi board colors , this cooler allows room for a antec spot fan on the msi boards HOT Power mossfets, the extra room around the center of the motherboard is nice.I cant hear the pump .I had to modify the backing plate which is made of durable plastic/resin material. the msi p55 board has two cpu retention bolt heads which do not allow the backing plate to sit flush , may not be a big issue as is but?, I just filed clearance with a chainsaw file, semi circle cut was all it took ,looks like it was made that way now.kinda ruins warrenty though .only $50-60 on sale , good deal , tried it and like it so far.

Fan is loud (I recommend replacing it with 2x noctua NF-P12s). No detailed best installation method or guide. Just watch youtube videos and ur set. Replaced the pre-applied thermal compound with Arctic silver 5. The back mounting plate does not fit perfectly for Asus P8P67 Pro 1155 motherboard. This is because of the screws for the backplate of the cpu mount onto the motherboard are kinda in the way of the mounting plate of the coolit eco alc. (if that makes sense) It still works though.Very similar to H50Performance wise, Its average. If you want instant maintenance free watercooling get this.

This heatsink is really efficient and really good looking with my G.Skill RAM and blue fans. The radiator collects a lot of dust but so does the rest of the computer so it's no big deal.It took myself and 2 other friends to tighten it down onto the board, so when you're installing it make sure you've got something firm and clean to press against the back for stability. The tubes that connect the radiator to the part that attaches to the CPU are SOOO inflexible I can't even close my computer case. Apart from that it's completely self contained so just plug it in and turn everything on. Oh yeah, and make sure you read the instructions so you don't break it or your build. I strongly recommend this to a friend provided their case is big enough. Would definitely buy again.
