Nine Big Air Coolers For Intel's Haswell CPUs, Reviewed

By

Intel's Haswell-based CPUs have a unique cooling problem that leaves many overclockers in a quandary. Today, we're rounding up nine different sink and fan combinations to see if any can contend with the fourth-gen Core processor's copious heat.

Ashura Installation

As with most coolers that employ standoffs, the Ashura uses insulated washers to prevent motherboard scratches and shorts. Those washers aren’t attached to the standoffs, however, and must be positioned over the holes first (bottom-left of photo below).

The standoffs (bottom-right of photo above) screw into corresponding holes in the under-motherboard support plate and are topped with mounting brackets (top of photo). Screws (top-right) hold the mounting bracket in place.

A cross brace installs over the Ashura’s base, screwing to the mounting brackets to hold the base tightly against the CPU.

The fan can be clipped onto the heat sink at various heights above the motherboard, providing either added DIMM clearance or added airflow under the fins, which can reduce a motheboard’s voltage regulator temperature.

    No NH D14?

    The CM H212 Evo has been a crowd favorite for quite some time now. :) I wonder how that might have performed. :D

    Water cooling is the best way forward: less noise, energy efficient and low maintenance.

    I hate to say it but all this article demonstrated to me is that Haswell is in no way better than Ivy Bridge. Even Ivy Bridge used 25% less energy with a 10% boost when compared to Sandy Bridge, and I can still get IB to 4.8 GHz on air.

    Haswell= 10% more power for 10% more energy and 10% less headroom. Oh and it costs more...

    Man I hope AMD can whip them back into shape with Steam Roller...

    I can't even fathom why one would spend this much time to write an article like this and still leave the NH-D14 out.

    It's funny how some of you guys still think Intel made Haswell with desktops in mind. This is a CPU architecture made for mobile. It's quite sufficient for desktops in every regard. Yes, it might not outperform IB by much, and it might run a bit hotter, but in a laptop, there is nothing that compares to Haswell.

    Noctua picked the NH-U14S instead of the D14. Please feel free to ask them why.

    Since Noctua chose not to feature the NH-D14 this time, you might want to look at its closest competitor. The article links a comparison of Phanteks TCP14E and NH-D14. Since Phanteks chose to keep its big cooler in the running but Noctua chose otherwise, this was the closest "frame of reference" available.

    I can't even fathom why you would repeat the first post without regard to any response. And speaking of a response, please read above.

    Really disappointed that there was no be quiet! and Cooler Master representatives. I would enjoy seeing how a Dark Rock Pro 2 or a V8 GTS/V6 GT.

    The comments are correct concerning the omission of the NH-D14 from this testing. It really doesn't matter a damn what "Noctua picked," that is not the issue. The FACT is the D14 is legendary for its cooling and to leave it out of any major test is just plain stupid. Don't forget that it won your last competition for best cooler.

    To say compare it's performance with the Plantek's performance is lame. Use some common sense when you do these reviews.
