Results: Cooling And Fan Speed

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

The most noticeable feature of our temperature charts is the narrow range of approximately 12° between highest and lowest CPU core temperatures. Dismantled Core i7-4770s suggest that this is due to the interface material Intel uses. At best, this shows that huge improvements in cooling technology are needed to create relatively small drops in temperature.

The results are also the average of all four highest temperatures, and some cores run hotter than others.

Scythe’s Ashura is the hottest cooler to stay under the processor’s 100° limit at a room temperature of 23°. Zalman’s CNPS10X Optima failed the test at just over 21° room temperature, and hours of extra A/C were required to get the room cold enough to finish Argon AR01 and Night Hawk Frostbourne measurements.

We might have blamed Xigmatek’s white paint for the cooler’s inability to cope with a Haswell-based CPU at a mere 1.25 V, if not for the audible cues to fan speed. The slower speed likely corresponds to less airflow, though fin design is also a potential factor.

    I don't understand why would you use Silverstone AR01 (which is the cheapest version and entry level cooler) when you have the much better AR03?!

    Like the looks of the assassin, especially with its MF DOOM box art!

    why test the inferior NH-U14S ? They should have tested the NH-D14. Everyone knows this is the best cooler on the planet.

    Also why wasn't the BeQuiet Dark Rock Pro 2 tested ?

    Aren't they largely a UK/Europe-centric company?

    (I know that the articles are mostly written in USA, but) looking at the TLD of this website, I see this as a further reason to include it.
