Hydro Series H70 CORE builds on the award-winning legacy of CORSAIR’s original H70 cooler, with one key difference: you supply your own fans. If you've already built a high-performance PC system (or three), you probably have a few extra 120mm fans lying around. Or, you might just want to choose your own fans. Either way, the H70 CORE gives you the freedom to fully customize your cooling performance.

  • newegg 38mm Double-thick Radiator The physics are simple: larger radiators have more surface area, and more surface area means more efficient heat transfer. The H70 CORE radiator is twice as thick as the standard radiator to provide excellent cooling potential.
  • newegg Easy Installation, Zero Maintenance You no longer need to invest into complex modular watercooling systems with half a dozen components to get serious CPU cooling performance. Each Hydro Series Liquid CPU Cooler is a sealed, closed-loop system that comes pre-filled and never needs refilling. Tubing is constructed from low-evaporation FEP for a long lifespan. Even the thermal compound is pre-applied. You'll be up and running in minutes.

5 out of 5 eggsBeast Cooler

Pros: Put some high power fans on this and you will be surprised. I have gotten better temps than a friend with an h100 and stock fans. My 3770k has been at 4.6 for a long time now, and the highest I've hit ever was about 75C when not in an extremely hot area.

Cons: None.

Other Thoughts: You cant get any better for the price.

Other Thoughts: none

5 out of 5 eggspassable to oc my 3770k

Pros: effective cooling for my 3770k only one fan in pull config @ 1500 rpm idles 31-32 no oc/ 40-41 @ 4.7
getting a stable 4.7 from my 3770k
under load gets close to 80

Cons: with the extra thickness push pull would block my ram.
still gets 5 eggs

Other Thoughts: still worthy cooling but i'm thinking of switching to a 240 rad like the asetek lclc 240
and getting a second fan to push push perhaps this will drop some temps and quieten down the noise

5 out of 5 eggsworks great at ~140watts

Pros: works great upto about 140watts

Cons: limitation seems to be in the pump or water block so going with some SUPER HUGE 250+CFM fans prob wont do much good.

Other Thoughts: I've used high end water cooling setups in the past that cost 6x as much as this and im very satisfied with the performance of this one. I'm using 2x120mm fans (push/pull) that are each rated for ~130CFM.
At ~140watts running BOINC it's holding 53c at about 50% pump flow, fan flow with ambient temps at 25C/77F. with prime-95 (same setup) it maxes at 64c on 100% pump/fan flow.

4 out of 5 eggsIdle temps 5 degrees above ambient. Need I say more?

Pros: Yes, yes I need say more...

This is an upgrade from my H50 which has served me well for the last 4 years, and it uses the same mounting hardware so I didn't even need to swap the bracket...just removed the H50 and dropped the H70 in its place (after some cleanup of course). The old unit had survived a few processors so I was using Arctic Silver 5 on that pump...this unit dropped my CPU temps by almost 10 degrees over the (aging) H50, needless to say I am quite pleased to see my 16% OC'd Phenom II running at 28 degrees C as I am writing this, and mid-high 30's under load. I stuck with the stock thermal compound and it seems to be doing a great job.

There's so much to love, it's low profile preserving airflow, and the tubes are more flexible (see cons) than the H50 allowing easier placement and slightly tighter corners. I prefer the round pump head to the square ones on other Corsair water coolers. Easy to install (from my perspective anyway, I've seen complaints).

I love the rotating connectors on the pump head, they allow perfect placement of the tubes and nice clean lines. I could even lay them out 180 degrees apart and run the tubes around my memory if I wanted.

Cons: The tubes are more flexible (and shorter than the H50), but are prone to kinking if you bend them too far, and the placement on the right side of the pump (as opposed to the bottom on the H50) means that putting them on the front of your case requires a 180 degree turn on the tubes, pushing their limits...if my case was any shorter, they'd probably end up pinched. The tubing arrangement forced me into only one possible mounting orientation for the radiator in the front of my case, and one in the back. Mounting in the back forces you to run the tubes back over the pump, hiding it...which would be a shame, but I prefer fresh air for the radiator so no worries there. I'd really prefer the tubes were mounted on the bottom.

The wires on the pump do not have mesh wraps...I was very disappointed to see this, so I covered them up myself. The H50 had them, I just feel it gives an impression of quality. The fan connectors might be nice for some, but I don't need them and see it as an extra wire to deal with...I was tempted to cut it off completely.

The unit arrived with several bent fins on the radiator. I saw this in one other comment...these fins are DEFINITELY thinner/weaker than those on the H50, another disappointment, as I was always impressed with how rugged the H50 radiator was...this one won't take any abuse so handle with care and try not to touch the fins.

Other Thoughts: The radiator is bigger, and harder to accommodate inside the case, but this is the price you pay for those low temps, and this is certainly easier to place than a 120x240 radiator.

The label on the bottom of the radiator is facing my case window really bothers me...but I'm just a little OCD so I didn't put this in the cons.

All in all, very happy with this unit...It was tough to take away an egg but it just feels like a step down in quality from the H50 and I am now concerned about longevity of the actual pump...Got the H50 stowed away just in case it's needed.

If I listen very closely, I think I can hear my CPU's teeth chattering.

4 out of 5 eggsNot for an novice builder

Pros: Intel Core i7 3.6GHZ. Idling, it averages 30 C. Running a Prime95 stress test I maxed out at 63 C, which is great. With my previous PC using a Fan+Heatsink I'd hit the high 70's. It runs pretty quiet. It also has decently sleek look, although clear tubes would have been nice. It also comes with thermal compound pre-applied to the copper cold plate.

Cons: The Instructions are HORRIBLE! ABSOLUTELY HORRIBLE! I don't know who wrote them, but they lack all discernible communication skills.

They don't correctly explain how to attach the retention ring to the MoBo; and when following the pictures, the CPU plate did not fit into the bracket. I had to remove a few plastic spacers, put the CPU plate into the retention ring, and then screw the whole thing to the MoBo.

The hoses are a little stiff. With the ridiculous installation method above, they only made it that much more difficult.

Finally, no fan controlling. It's pretty quiet, so it's not that big of a deal.

Other Thoughts: If you've built a few computers in your day, you'll be able to figure out how to install this. Once you do install it, it works great. At the end of the day I WOULD buy this again and I WOULD recommend it to a friend.

MoBo: ASUS P9X79 Pro
CPU: Intel Core i7-3820 Sandy Bridge-E 3.6GHz
Graphics: EVGA 2Gb GeForce GTX 680
Ram: 2x8Gb G.Skill Ripjaw DDR3 1600

4 out of 5 eggsCouple of issues, but pretty cool

Pros: Dropped the temperature on my Sandy Bridge E by over 10C. Despite the bad installation instructions, once you figure it out, it is pretty easy to install.

Cons: Bad instructions is the first thing to notice, i.e. plastic knobs go on the screw holes on the bracket before you install it.

I am removing an egg because this unit comes with only a two pin connector. Effectively, this means that the fan will be blasting at full speed all the time, make sure to pick a quiet fan.

Other Thoughts: I am getting high 60s temperature on 6 core SBE at full load in a relatively warm room (maybe 77F). When I mean full load, I mean MATLAB with 12 threads working at 100%, this is a lot more than the regular games would do.

The radiator may not fit in all boxes, mine is pretty big, but you should read and measure for your box.
