Customer Ratings & Reviews

I was playing an intense graphics game when suddenly the frame speed slowed to a crawl and before the system just shut down and would not reboot. The immediate suspect was my six-month-old Corsair cpu water cooler. Cover off hand on the pump and the problem was immediately identified. The pump was very hot, the hoses leaving it, very cool. Ten minutes later when the cpu had air-cooled, my six month old computer kicked off and ran until the cpu overheated again. Same symptoms, dead in the water. I attached power to the water pump and tapped it lightly with a screwdriver. It was dead silent and would not start. I replaced it the next day with this new model. Immediately, my computer worked well and has for the last two months. The first part failed after six months. Sad. I have used corsair coolers for years with no problems except an old one which started showing the effects of anti-freeze evaporating around one of the fittings. That pump is now retired too but it lasted eight years, no problem there. This new model was a total disappointment and judging by online ratings, my problem is persistent problem. After the new cooler was installed, I hooked up power to the old part again and, holding the hoses, slapped it into my open hand. Lo and Behold, the stupid thing started working again. It spun up and works fine. Sadly, I don't trust it. I hope Corsair replaces it although it is now doubtful since it works. I never had any problems with the old design. This new design is questionable. The fans are noisy at full speed and the hoses are very stiff. I hope this new one works longer than six months. Already, the cost for this cooler is doubled. Corsair offers a good warranty but who can wait days or weeks without a computer for them to fulfill their warranty. This user can't.

Great CPU water cooler usually designated for larger cases. Make sure the size of the radiator and fans can fit into your computer!

Works great and no issues. Keeps the processor 10c degrees cooler than the stock air fan cooler. A must for overclocking the processor.

I purchased this after the one I ordered from a different company was a dud. It was very easy to install and has been working perfectly.

Bought for Ryzen 7 1700. 1700 came with a cooler but I wanted to OC so I got this cooler for reassurance. Not disappointed.

Dropped my overheating processor by 80 degrees. You'll need thermal paste though. What comes with this product isn't sufficient.

This product gets the job done for sure! I managed to overclock my processor to 4.5 GHz while maintaining a reasonable temperature.

Also it's big, really big. Make sure you got a huge case. Full Atx case. I love this item. Keeps my i7 7700k nice and cool.

CPU never overheats anymore - only thing the cables are stiff - i had to relocate a case fan to fit with my tall ram chips

Keeps CPU very cool, even for over clocking. Never gets over 35 degrees Celsius with full load. Runs around 27 on idle.

Bought this for my home PC as the default air cooler wasn't cutting it. This did the trick and was easy enough to install.

One of the best cpu coolers for an aio system that you could ask for works flawlessly in one of my gaming rigs.

an excellent cpu cooler. available corsair link keeps you posted as to temperatures of cpu, gpu, motherboard, fan speeds, etc.

I found that this keeps all CPU temperature below 30 degrees Celsius. Even under load, it stayed cool. Ive not tried overclocking, but am sure it would do a good job. Worth the buy.

over still works but had a problem with the pump. it stopped took it apart and found out it gummed up inside cleaned it again and it worked find again

This is an excellent cooler! My computer does not get warm with heavy use. I have not stress tested yet.

I got a great deal on it and it's in my new i7 build and works as advertised. I only wished they had other case in the Corsair Link app to places on the thermal points correctly.

This is a great cooler. Keep my cpu temps low and cool. I have a I7-7700k and it runs pretty cool with cooler on.

Super quiet cooler! Keeps it around 60 degrees under full load. I love it! When its on idle it doesn't make any noise.

Excellent cooler, one of the best you can buy and an excellent value purchase
