The Corsair Hydro Series H70 is the best choice for high performance CPU cooling. A worthy big brother to the already excellent Hydro Series H50, the H70 improves upon the design in every way.

A low profile pump and improved cold plate allow for even easier mounting to your CPU. Compatibility with all modern AMD and Intel desktop CPU sockets is included in the box. A higher-performance radiator with nearly twice the surface provides even more room for liquid to get cool before it returns to the cold plate.

If that isn't enough, the Hydro Series H70 comes with twin high-performance 120mm fans, optimized for a push-pull configuration, to allow maximum airflow through the radiator. The Corsair Hydro Series H70 is the best choice for a high performance CPU cooler on the market, bar none.

  • newegg Self-Contained Closed-loop System The Corsair Cooling Hydro Series H70 features a pre-filled closed-loop design with integrated pump and reservoir for zero maintenance and easy installation.
  • newegg Exceptional Cooling Performance The Corsair Cooling Hydro Series H70 employs a copper base, a large, double-thick 120mm radiator for outstanding heat dissipation and twin 120mm high-performance fans for outrageous airflow in push-pull configuration, delivering superior cooling for higher overclocking performance and greater system stability.
  • newegg Fan Speed Adjustable The included step-down adapters let you customize your fan speed for low noise or high performance.
  • newegg Universal Socket Compatibility The Corsair Cooling Hydro Series H70 features broad compatibility with Intel Socket LGA775, 1156 and LGA1366, as well as AMD Socket AM2 and AM3.

5 out of 5 eggsKeeps CPUs cool

Pros: Keeps my CPU cool at 4.2 GHz.
(4.4 GHz still cool, but I can't get it stable with voltages I'm comfortable with.)

Doesn't have space issues with RAM close to CPU like a normal heatsink.

Easier to maintain than custom water cooling.

Looks very nice in an Antec 1200 case.

Cons: The mounting brackets are terrible. Very flimsy and barely able to secure as well as it needs to. I know the H80i brackets are much better, shame that wasn't out when I built my system.

With using both push and pull fans it is hard to fit alongside a side mounted fan. Had to cut unneeded plastic edge off the side fan.

Other Thoughts: Bought this 5 years ago and still running strong.

5 out of 5 eggs

4 out of 5 eggs

Pros: This keeps an overclocked AMD 1090T (4.1GHz) very happy and cool. It is very quiet and totally trouble free in operation. Under max load the CPU temp rarely gets above 47ºC.

Cons: My only complaint is that the tubing is pretty stiff compared to the tubing available from the custom cooling system suppliers.

Other Thoughts: My next build for a friend will be using the H100 cooler top mounted in his case and it looks like there will not be the need to bend the tubing so it should be easier to install.

5 out of 5 eggsSilent as the Grave

Pros: An outstanding cooling system that is as silent as the grave. No big wizzing sounds as it starts up, no big wizzing sounds as I put my 1090T through its paces.

Cons: Not as easy to install as some others out there, but if you watch the install video once or twice you can get it done with a minimum of fuss.

Other Thoughts: I have never heard a peep out of this thing, even when I am stressing my processor pretty hard. Temps have never gotten above 55C, I wish they made something for our Northbridge chips like this.

5 out of 5 eggsTl;dr Quick summary

Pros: The liquid cooling allows cool air to blow through the system, this type of technology allows for not only a quiet fan but also cool air, this computer hasn't heated my room at all, even the plastic on my casing is cool. The fan works wonderfully and Im using it at standard manufacture settings.

Cons: It was a bit odd finding out how to properly install the fans and the liquid cooling system together without damaging it but it was well worth the patience.

Other Thoughts: Great cooling system, wouldn't recommend any other.

4 out of 5 eggsPower User Standard

Pros: Keeps my high-end, dual-boot Hackintosh running exceptionally cool.

Cons: Noisy, Big Fan, Not transparent (not really an issue though)

Other Thoughts: I wish they could license Dyson technology to make the fan smaller and silent.

4 out of 5 eggsH70 is noisy, but really good

Pros: Good performance. Keeps the i7 2600k@4.5 around 28C idle (at 20C ambient). At load, it rarely hits above 45C

Fairly easy to install and no clearance issues.

Cons: Fan noise level is too loud. Replaced both fans with two Logisys SF120 ultra-quiet 120mm rubber fans. Makes a HUGE difference.

Radiator is large. Fans on both end makes it very large. Mounted one of the fans outside the case.

Other Thoughts: Be aware that this thing is loud. I wish Corsair would rethink the fans. For me, a major prerequisite for a water cooling system should be how quiet it is.

Radiator seems to work best when pulling air from the outside and using the top case fan (Coolermaster Sniper) to exhaust hot air (it's rising anyhow).

5 out of 5 eggsHappy with this CPU cooling

Pros: Easy to install, perfect fit, does a great job of keeping my 1100T OC'd to 4.0Ghz very cool. So cool in fact that I forget it's OC'd, I have a 3.2 Ghz processor running at 4.0 as it's full time working configuration and the highest temp it's logged is 48.8C under full load for a period of hours. I had to push more juice to the CPU than I like so though I could get more clock out of the CPU I'm comfortable with the balance I've got now regarding processor life. I have Arctic 5 and other high end pastes but I didn't use them, I just slapped this on the board, mounted it, then mounted the board. I'm glad I didn't muck about with thermal paste, turns out there was no need. There is nothing wrong with this design or hardware. If you're getting less than excellent results you either have a defective unit or PEBKAC.

Cons: Doesn't do laundry or wash my truck.

Dickweeds that expect hardware to perform magic tricks.

Other Thoughts: I have this in a Cooler Master HAF 940 case, there are 2 double slot video cards, one single slot video card, a TV tuner, and a PCI USB card on an MSI 890FXA0-GD70, no more room for add-on cards and lots of heat. My H70 is pulling cool air from outside the back of the case, which is then pulled out the top of the case by a 240mm fan. I had to mod mount another 140mm fan blowing on my video cards to move the heat out from between them and the rest of the cards.

All of these fans and the pump are controlled by MB fan headers and an NZXT external fan controller (and the video cards fans by EVGA Precision), I can fine tune airflow however I like. Noise isn't an issue.

You can't pull hot air from inside a case over a radiator and expect it to cool your CPU. The real advantage of this unit is that you can place it to run cool ambient air from outside the case over it. You need a case that can dump that heat or else this won't work any better than air. It's thermodynamics, not mag
