Testing Results: Low Fan Speed

As most users don't actually need the fans of a tower cooler running at peak performance (and peak noise), let's also take a look at what kind of performance these coolers provide at lower fan speeds.

Broadly speaking, all four of the coolers that we tested for this review were capable of sustaining reasonable operating temperatures with thermal loads above 200 Watts, even with the speed of their fans greatly reduced.

Fan Speed (7 Volts)

Noise level

There are virtually no differences between these four coolers in relation to our previous test, with the Thermalright True Spirit 140 Direct again displaying the best overall thermal resistance and excellent efficiency with the handling of low thermal loads. However, the Noctua NH-U14S greatly outperforms all other coolers when it comes to the handling of very high thermal loads, suggesting that it can maintain reasonable operating temperatures on overclocked processors alongside with virtually inaudible noise levels.

Average Thermal Resistance

Once again, the Be Quiet! Shadow Rock Slim falls slightly behind the Noctua NH-U14S and the Thermalright True Spirit 140 Direct. The thermal resistance is only slightly worse but this time the Shadow Rock Slim also has no real advantage in terms of acoustics, as the difference between all four of the coolers is practically indiscernible.

Core Temperature, Constant Thermal Load (Low Fan Speed)

Finally, the Phanteks PH-TC14S displayed the lowest overall performance figures, with slightly worse thermal resistance than all of the coolers in this roundup review. Although the Phanteks PH-TC14S displays thermal performance similar to that of the other coolers at lower loads, the difference widens greatly when the thermal load is very high, suggesting that the cooler is at its limit in handling the excessive thermal energy flow.

    For online comments, there's shills, then there is everyone else. Shills which are just trying to spread around this meme that X company's products are the best thing sliced bread.

    Just buy whatever you want, regardless what anyone else thinks. Don't pay brands any particular attention, just buy the best product you can for the best price you can and pocket your savings.

    Nice, mature response, with the name calling and all. Grow up, then read the actual review. The reviewer said the same thing I did. Now, go read a few more reviews of coolers, and you'll find that virtually all of them agree with this review. Noctua is expensive, but worth it. Generally I agree with you - it doesn't pay to go by brand name - but there are exceptions, and Noctua is one of them.

    Noctua also costs a lot more than the competition. So when you're adding 35% to the price tag of any of the other products tested then you usually expect better performance (not mandatory though). So drawing the conclusion that Noctua is king of the hill in general isn't that useful.

    So... there are expensive products, then there are cheaper products :). For some people 35% markup might not be worth the extra performance.

    So? If you want the best you often have to pay more for it.

    The "best" is the best.

    If you want the "best within a price bracket" THEN you can finagle and weigh things against each other.

    Does Noctua pay you in stock, dividends, or a salary to promote their products online? If not, why do you go out of your way to promote free advertising to another company who you owe nothing to? You made your trade; your money for their product, there's no stipulation that you have to continue to sing praises for their company for other people to be more negotiable to give that same company more money for more products.

    Likewise, if you're upset about being called out on literal shilling, then it's really you that needs to grow up.

    Additionally, the performance roundup review written by E. Fylladitakis doesn't have anything in common with your post, which you attribute as stating that "(t)he reviewer said the same thing I did". Fylladitakis makes no catch-all branding statement. They evaluate the four products, they make the measurements, they compare the measurements, then make a conclusion about the products based on the measurements.

    YOU, however, are making a blanket statement about all performance CPU cooling products developed by Noctua being "superior in virtually every respects, especially quality and support."

    Those statements can't be anymore unalike in any way. The former was a controlled experiment to evaluate product performance followed by an analysis of the products, the latter (your comment) is an opinion; void of any metric of data or analysis.

    If you look at the thermal performance in this roundup, it shows that the Thermalright cooler (at $47, the cheapest of the four measured in this roundup) to have the best thermal performance at low temperature loads (where most performance PCs, the target audience of these $50 tower cooling solutions, stay outside of gaming or benchmark loads), theorized by Fylladitakis to be due to the direct contact design of the heatpipes, and a close-second (literally 16.6 vs 16.8 degrees Celsius delta over ambient, figures well within a margin of error of measurement) at 150W loads (where most overclocked mainstream CPUs will sit at full load), and still competes closely at completely unrealistic synthetic 340W loads.

    So given a $47 price for the Thermalright vs $65 price for the Noctua, given similar performance figures, it's pretty apparent which has the better value for mainstream performance PCs.

    I love a vigorous discussion, but you guys need to cool it, please. There is no place for profanity here on AnandTech.
  • mgilbert - Wednesday, May 24, 2017 - link

    Yet, my post gets deleted, but not his, despite its divisive, hateful, argumentative, obtuse, disrespectful, inappropriate nature. Sounds like four letter words aren't the only thing not allowed on Anandtech. Fairness has no place, either.
  • Ryan Smith - Wednesday, May 24, 2017 - link

    I have made my ruling. I give you guys exceptional leeway as I believe you need to be free to discuss technical matters, but I draw the line at profanity and pointless ranting. You guys are done, please move on.

    If you wish to discuss it in private please email me.

    We love you Ryan! Even when we complain, whine and moan about x, y, or z not being tested the specific way WE would do it, we love you!

    Ruh-roh, now I"m shilling for Anandtech! Don't worry, my username checks out.

    I have to agree, Noctua is the best. I do recommend the Hyper 212 for budget builds though.
