Corsair H70: Next-Gen Self-Contained Liquid Cooling

Features

Liquid cooling still has the image of being expensive and complicated. Corsair, in cooperation with the cooling specialists at Asetek, now offers the H70 that aims to simplify the step up from air cooling. Can it beat less expensive premium heatsinks?

Comparison Table: Temperatures

Note: Heat sinks that ship without any included fans were equipped with a standard fan from the 3RSystem Iceage Prima Boss. It has performs similar to a NoiseBlocker Multiframe M12PS.

The Corsair H70 liquid cooling system scores a low 38° C with the fans set to high, about the same temperature as the air CPU coolers Prolimatech Megahalems (Rev. B), or the Zalman CNPS 10X Extreme, and is thus placed pretty high up on the chart.

In our preferred configuration with two fans and automatic motherboard fan control, the Corsair H70 is at about the same level as a Noctua NH-D14--at least in terms of cooling performance. In this chart, the all-in-one liquid cooling system is definitely up there at the top. However, looking at the noise level chart at the next page, things get a bit complicated.

    "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.

    I think its stupid, just look @ the Prolimatech's...

    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.

    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.
