Corsair H70: Next-Gen Self-Contained Liquid Cooling

Corsair H70: Design And Technical Data

Delivery

The Corsair H70 prefab liquid cooling system comes in a sturdy cardboard box. In addition to the already-filled, closed loop cooling system consisting of radiator, hoses, and water block with built-in pump, we find detailed installation instructions and mounting hardware for different computer platforms in the package. The Corsair H70 supports Intel's LGA 775, 1366, 1156 interfaces, along with AMD's AM2 and AM3 sockets.

Additionally, the Corsair H70 cooling system includes two fans that operate at 2000 RPM. The included adapter cables with embedded resistors (~30 ohms) can be used to bring the fans down to 1600 RPM for quieter operation. There is no thermal compound included, which most coolers usually do bundle.

Compact Water Block

Instead, Corsair opts to cover the CPU water block base with a layer of thermal compound straight from the factory. This thermal compound is protected by a solid and easily removable plastic cap that is attached to the underside of the water block, protecting it from damage during transport.

Hardcore cooling enthusiasts would likely remove the compound and replace it with a thin layer of something more expensive, but obviously this is not mandatory.

With a height of just two inches, the water block is very compact. The low profile is even more notable when you consider that the pump is integrated with the water block, driving the coolant through the closed loop system. A cable connects the pump and the motherboard, supplying the pump with 12 V power. The pump is extremely quiet; only in a completely silent environment were we able to hear a faint hum.

Rigid Tubing

The coolant travels through the cooling system via two small and relatively rigid tubes. They have an outer diameter of about 8 mm and a length of about 24 cm. The tubes are attached to the pipes in such a secure way that they can only be replaced with great effort. Except for the water block, the loop also includes the radiator. Due to the short length of the cables, you might not be able to install the radiator exactly wherever you want to if you are using a large computer case.

    where's the H50 in the charts?

    Overpriced, equal to or gets beat by air cooling in temps, and is pretty loud...Doesn't sound like a very good product ?__?

    The prolimatech and noctua offerings are much better.

    "street price of around $110, it is reasonably priced" -too high.
    "slightly elevated background noise" -understatement

    You will be better served by the h50, yes its weaker but its cheaper and quieter and performs close to the same. Do yourself a favor and avoid this product although it is quite good.

    Would it be possible to post combined charts of idle temp/noise and full load temp/noise ? IMHO that would be more informative than plain bars, as many are interested in balance of those characteristics.

    I had expected to see even the CM Hyper 212+ results...
    IMO $110 for such a cooler not worth it,...Other good option if going for a closed loop cooler would be the CoolIT SYSTEMS ECO...

    I would have also liked to have seen comparison between a push/pull exhaust, and a push/pull intake.

    For my H50, it is quite explicit that the radiator should be pulling outside air through the fins. And yet, people keep it as an exhaust and then lament of their temps.

    One of the biggest perks of a closed loop water cooling system is you dictate what air is being used. Where-as big air is always restricted to case air(unless a side is removed and a box fan is added)

    I would have also liked to of seen it as a delta above ambient, rather than a flat CPU temperature comparison. I personally process the delta better, and lend more credence to it.

    would have liked to see the temps in passive mode, with no fans, and on a more recent CPU...

    I want one for my gfx card not the cpu. Its my gfx thats noisy. I don't care about cooling temps or overclocking as long as the cooling is adequate. I just want sweet silence :).

    I guess you missed the part where it was the noisiest thing on the list with a 57.3 dB at max?

    Also considering the TDP of some of these GPUs are between 190 and 300W, you can expect the H70 to work much harder thant he sample 130W CPU. So it will most likely be loud all the time because of the higher operating temps of the GPU.

    pentium d's best performance!

    Someone explain why they are using a pentium D for the test.
    I want to see the results on 1366/1156 CPU not an old pentium d.

    Isn't the point of water cooling to not have fans to deal with?

    The reason is clearly stated in the page about the test configuration. RTFM.

    I could care less if the Pentium D is less efficient than a 1366/1156 CPU. People dont really need to know the coolers results on an old Pentium D.
    Yes, I know that more than likely if it performs good on the Pentium D then it will definitely perform good with the i7, Blah Blah Blah, show me, That is what people want to see. For someone who dont know and is looking for a good review on how the H70 performs on the i7/i5 this review is pretty much useless to them.

    It is one thing to test new components on the Core2 CPUs but an old Pentium D come on. Even an old 45nm Core2quad or C2D would be less efficient than an i7/i5, not only that more people own the C2Q/C2D.

    Perhaps I missed something but:

    - which configuration was used? push/pull
    - air from outside the case or the inside

    The orginal fans included with the H50/70 are crap. The firt thing I did, changed them for 2 Scythe fans. The temperatur is much better, the same thing for noise level.

    Want to see what this cooler is realy capable of:

    It's german but you don't have to understand the language to interprete the charts, particularly "H70 @ 2 Serienlüfter @ 1.600 1/min

    This isn't real watercooling, and H50/H70's are known to have weaknesses and flaws. H50's were prone to leaking, and on both units, the pump is INCREDIBLY underpowered. You are MUCH better using a high quality air cooler for your CPU.

    Yes, Corsair and a few of these companies making these *cough* CRAP *cough* self contained coolers also make crap GPU coolers for those of you interested.

    I'd suggest you check out the Forums > Overclocking > Coolers and Heatsinks for more discussions on Tom's (I am a regular for watercooling out there) as well as Overclock.net forums...or Xtremesystems forums. Creating an 'idiot proof' watercooling unit like this needs to be a much better performing unit if they are charging this...there are far better alternatives for beginners for watercooling.

    Have to agree with other sentiments expressed. If there are air coolers that match the performance of h70, then h70 is a failure at being much more than a gimmick.

    They should offer 240 and 360 models, 120 just doesn't dissipate enough heat.

    @kelemvor4:

    You are quite correct. For the price/performance curve, it fails against other air coolers costing more than 50% less.

    Flat performance vs. even beginner watercooling is dismal...even against the ThermalTake bigwater kits...which we all try to steer others away from.

    The radiator needs to be at least a 220 AND offer better flow rates. Their site doesn't even state what the pump flow is...but a few have done some tests and its very pathetic.

    Gimmick? Yes, very much.
