Experience: 11 Months


-Pretty good craftsmanship
-A few dents, scratches and paint chips here and there
-Included fans are noisey
-AM3 Bracket cracked (Uses bad back-side motherboard mounting system w/ sticky stuff). VERY hard to remove!
-Good performance wise biggest cons are the included fan noise & bad mounting system for the backside of the motherboard using REALLY sticky material. This makes it almost impossible to remove the bracket without it breaking!

Experience: 1 Weeks


- Great Cooling Performance
- Push/Pull Configuration allows for use of two silent fans rather than a single strong one.
- Easy to Install
- Works on LGA1155 though not specified (well LGA 1156 coolers usually work on 1155).
- Tubing is not very flexible.
- Closed Ended Loop: Cannot add other devices to the loops.
I bought this as part of a whole new system for my cousin. I got to piece the whole thing together.

Easily handles an Intel 2500K oc'ed to 4.5GHz. Not only that I replaced the fans with Enermax 900RPM Twister Silent fans in a rather small NZXT Cube case. Still keeps the CPU cool.

Rather impressed with this product.

Very efficient
Easy to install
The cables for the fans are a bit short.
This unit is very efficient, I'm currently running my i5-2500k y 4.5 GHz and the temps doesn't exceed 40° under load. The installation is easy except for the part of screwing the pump in place, you might need help.

Experience: 3 Weeks


-good performance
-thick rad
-loud fans
-crappy mounting system
this is a pretty high performance liquid cooler and its work it,

- Keep CPU cool, really cool
- Very silent
- Hard to bend tubing in place
- Use too much motherboard "fan connections"
Very pleased with this buy, kinda hard to install when you're alone, but manageable, tip, use someone to hold the radiator while you're screwing the first screw, the first one is hard to align.

Very very worth the buy, push heat directly out of the case if you don't follow the instructions, my Q8200 2.33GHz is now running at room temperature, and 2 degrees over room temp. when overclocked at 2.8GHz, it's a difference of 10 degrees when I used my old Thermaltake silent tower, and even more when overclocked.

Would definitely suggest it to a friend.

looks cool, works good
bit big, fans it comes with kinda loud
I bought this because my noctua cooler didn't come with 1155 brackets.

the back bracket this has for the intel motherboards has these little liners for the screws you need to insert  into little holes depending on your socket, took me a couple minutes to get them in right, other than that easy install.

i have an antec 900 case, it BARELY fits, i had to cut off one of the clips for the lid fan to get it to fit,

i didn't use the fans it came with i used a noctua fan and kept the blue LED antec 3-speed.

i use a i7 2600k, my case maintains an ambient temp of 27c and prime95 with hyperthreading on it pegs at 63c, idles at 34c

so really good :D

Tricky to install yourself
What an amazing product, this keeps my CPU really cool, well worth the $$$ and you wont be disappointed, I paid the extra money and had NCIX install it. You will be glad you did

works very well looks ok
on air filter I think if you are taking air from out side of your case it shoud be filtered in
I have this mounted in a antec df35 l looks ok will alow me to up grade motherboard to eny thing out thare and some say it's loud not to me 25c cpu 25c on ram 35c gpu 1/3 loud not bad for
a q8200 asus p5p43td 4 gb ddr3 1333 ram gtx260 core 216 I like and on my bilds I am going to sugest it.

Good performance cooler.

Very good performance nice and quite, still wondering do I need such big cooler for my first build computer. without the heavey use such as gaming. my CPU temp. barely go over 40. don't know because of it or other reason.

My i7 2600k temperature under load is only ~50C. Haven't overclocked yet but 50C is pretty impressive even for stock speed. Its also very quiet. Pretty flexible and reasonable price.
Had issues mounting the radiator to my case. This was honestly the hardest thing to do about building my system.
The H70 is a great cooling solution. My only issue was the installation part of it but otherwise I would recommend it for anyone looking into liquid cooling.

Comment: If you are looking for an all in one water cooling solution, look no further; Corsair has just what you need right here.
Posted by: BernardP @02/22/11
Comment: The Corsair H70 is a strong improvement over the H50. This is not just a re-skin with a larger radiator.
Posted by: BernardP @02/04/11
Comment: If you are using a Core i5 or AMD processor and want to overclock, rest assured your temperatures will be much lower with the H70
Posted by: BernardP @02/03/11
Comment: Ahhh bigger. We like bigger. No matter what it is, when it comes to PC hardware, bigger is nearly universally better. Bigger hard-drives give more space. Bigger RAM gives improved application performance. Bigger heatsinks gives better cooling. The same is true of radiators. A bigger radiator in y

Comment: After reviewing several CPU air coolers, it is time we to test the top-shelf liquid cooling solution from Corsair: the H70. It is a complete sealed system, with easy installation and no maintenance. Let's see if it is really worthwhile picking this system over high-end air coolers.
Posted by: Andrew_S @01/18/11
Comment: A review of the H70 and its real life useage for both overclocking fans and day to day users.
Posted by: Ken_C @01/11/11
Comment: Like the H50, Corsair's H70 is a turnkey system that requires no assembly or maintenance, it is relatively easy to install, has very good cooling performance and is priced only slightly more than higher-end air coolers. The design is thoughtful and the materials and workmanship seem to be quite
Posted by: Andrew_S @12/06/10
Comment: Cools better than the single fan Vantage ALC for a few dollars less, but not as well as a Noctua NH-D14 nor is it as quiet.
Posted by: FirewireX @10/25/10
Comment: Legit Bottom Line: Corsair Hydro Series has come a long way and the Hydro Series H70 CWCH70 is the new king of the kit water coolers; and at $103 it’s a little more than high-end air, but nowhere near as bad (cost) as a full-on custom water cooling loop.
Posted by: IC9 @09/03/10
Comment: solid performance, 'tad' loud on full fan speed.
