Water cooling is typically seen for an enthusiast, requiring pumps, reservoirs, tubing, know-how, and a cautious mind not to spill water all over your precious components.  The benefits of water cooling are obvious to many – having your system run cooler, better stability at higher overclocks, and aesthetics.  Lower down the order of water cooling, manufacturers like CoolerMaster, Corsair and Coolit have over the years come to the market with all-in-one solutions, requiring little knowledge to reap water cooling benefits.  These early models were readily slated in reviews, for being more expensive than high-end air cooling, yet performing worse.  It wasn’t until the Corsair H50 and H50-1 models came along that these all-in-one water coolers were taken seriously, because here was a product that performed as good as a high end air cooler, in certain situations quieter, could easily fit in many cases, and only for a small premium.  So now Corsair is due to release the next model in their line – the Corsair H70.

The new cooler itself has been redesigned to almost half height, yet the principle is still the same – get excess heat away from the processor.  The radiator is now double the thickness (to 50mm) compared to the H50, and bundled with two dual-speed 120mm fans (1600 to 2000RPM, 31.5 dBA) for a push-pull configuration.  The coolant channels are now redesigned in the cooling block, allowing for quicker heat transfer from the CPU.

If the H70 performs better than the H50, as Corsair claims, the unit could be well placed between the high-end air coolers and full blown water cooling setups.  However, two major platforms stand in the way of this product.  The double thickness radiator will reduce the compatibility of the H70 in smaller cases – the H50 radiator is already quite thick, so double that and add a couple of fans, and it will hopefully fit in most ATX cases.  Next, is the price: pre-orders currently range in the $110-$115 (or £75-£85 in the UK), representing a $30 premium over the older H50-1.  This makes the H70 rather expensive for a CPU cooler, so in order to match this price, it should perform better than any air cooler available.

The Corsair H70 will feature brackets for Sockets 1366, 1156, 775, AM2 and AM3, and is expected to start shipping next week.

    Personally i don't like water cooling solutions. The technology should go in the way of developing better and better air cooling solutions. Air cooling also cools other components on the mobo. What's the point in having a cool CPU when other components nearby are cooking?

    Air is possibly one of the worst mediums for thermal conductivity. Much better is water running over your components in a water cooling system. Even better heat sinks would be gold, copper, silver, diamond, or graphene. But any of those in mass quantity would be prohibitively expensive for heat sinks. Water is by far the most economical and best performing solution (not counting some industrial oil solutions that are better) for whisking away heat.

    I agree with Nin.

    Personally, I like water cooling solutions. This technology when used properly is far better for cooling than air can ever be. Other components on the board can be cooled easily with a fan - if you are not capable of thinking ahead and doing that, you should not be near a PC in the first place. To top it off, I cannot think of any one air solution for CPUs that also cools an overclocked motherboard to the extent where nearby heat sinks are kept "cool" solely by its radiated air - at least not without a LOT of noise generation.

    As we move further towards platform integration there will be less outboard cooling to do anyway.

    Obviously you don't know much about cooling solutions eh mate?
    I suggest you don't come near a computer.

    Show me a decent CPU heat sink that cools all surrounding heat areas when the system is overclocked to the extent where an extra fan is not required.

    Be my guest. Check this out:

    Here is another one:

    I owned one of these once. Lowered the CPU and NB temps by 50% from around 65c to 30-35c under load

    Look at the size of it. I would rather have a radiator of that size for my CPU and put a couple of small fans near the NB and RAM.

    Now that would be stupid. Why would you do that for triple cost when you can have better results with this set?
  • dia - Friday, August 6, 2010 - link

    I'd get myself a PA120.2 and a decent water block and it would have more capacity than this.
