I used this to overclock an Intel 4770K. Running like a dream now and staying cool.

Keeps my overclocked 4790k nice and cool in the summer.

Keeps the cpu cool and runs quiet, great for overclocking! Only ran into a problem when I tried to plug in the Corsai Link cable but that was my motherboard manufacturers issue not Corsairs. It still runs fine without it so don't sweat it if you can't plug it in.

It fits in my tower, cools my components, and doesn't leak, so I'm pretty happy with it.

Worth the money great fit for custom builds. A little bulky but manageable

Hardware wise, everything works perfectly and at very low noise. Corsair Link was a pain to get to work properly but I did get it in the end.

So far so good! I always custom build my rigs and recently I renewed half the parts in my current PC (replaced the case, motherboard, gfx card, power supply and now CPU heatsink) and have had no issues yet. I play a variety of games on my machine and multitask, I've never seen CPU temps so low. Best part is the noise, there is none. The fans are silent, the pump is silent and I am satisfied.

This is the second unit i purchased (the first one was from a different store) with the same issue! The unit works great when it works. This is the second one I purchased, and the pump went out on it! If there was a way to fix, or replace it, that would be awesome. It does keep your CPU nice and cool, and can even do it quietly when the software is set to quiet. I really wish the pump was better on these because they're an excellent choice for watercooling on a budget. Super easy to install so anyone should be able to install in about 30 minutes. Personally, I'm looking into going custom so I can cool my CPU and GPU.

One of the best you can get at this price range. It's the newer version of the h100i and it fixed all the little bugs and issues the original version had. I'm extremely happy. Running i7-4790k overclocked to 4.5ghz and my computer idles around mid 30c.

Cpu is now at a sweet 20C. Easy install and overall nice build quality

I have had no problems with keeping everything cool. Even though its a closed system

i paird this with my I7-8700k and a MSI z390 mobo thats one click overclocked. <gameboost> in all games, and even movie encoding it has yet to go over 142 degrees F. its great! super easy setup. no issues what so ever.

So all the reviews said this was good and greatly reduced temps but I couldn't find numbers, here are mine Intel i5 4690K @3.5ghz under full load BEFORE cooler, 85C* Intel i5 4690K @4.4ghz under full load AFTER cooler around ~60C* For the price, and ease of install, this thing really REALLY improved my temps.

Very quick and easy to get setup, all powered direct from the motherboard, excellent aesthetics if your case has a window, with subtle lighting. keeps my old 4770K down at 30 degrees Celsius with minimum noise. Top marks for Corsairs gear.

Great liquid cooler for all purposes, minimized sound, excellent cooling ability

This thing works and works great. A bit pricey in my opinion but to suppress the heat that the new CPUs are putting out, it's needed.

Worked great as expected. (It does a great job of cooling the CPU).

Just what I need for my pc build and to kee everything running cool

Was able to overclock my core i7 from 4ghz to 4.4 with no issues.

This is a very nice piece and very quiet ! I would buy it again in the future
