Testing Results: Maximum Fan Speed

To start things off, let's take a look at the peak cooling performance of our four tower coolers. We should note that the Phanteks PH-TC14S is once again the oddity of this review, with its fan reaching 1520 RPM. The specifications of the PH-F140HP fan state a very broad maximum speed range of 1300 ± 250 RPM, so our reading is within the fan’s specifications, yet this is the first time that we have encountered a fan spinning that much faster than its rated speed.

Fan Speed (12 Volts)

Noise level

With their fans running at their maximum speed, the best overall thermal performance comes from Thermalright’s True Spirit 140 Direct. Noctua’s NH-U14S handles high loads a little better, but Thermalright’s offering has a very strong advantage at lower loads, suggesting more efficient heat transfer due to its direct contact design. 

Average Thermal Resistance

The Be Quiet! Shadow Rock Slim falls a little behind in terms of thermal performance but only by a couple of degrees, which is acceptable considering that it had the lowest noise reading of this review. Considering the overall design of the cooler and that it has a smaller number of heatpipes in comparison to every other cooler in this review, its top speed performance is surprisingly good.

Core Temperature, Constant Thermal Load (Max Fan Speed)

Although its thermal performance is satisfactory, the Phanteks PH-TC14S falls behind the other three coolers of this review. It is both slightly louder and less efficient, especially when it has to deal with very high thermal loads. The difference however is small and a more carefully designed revision can easily turn the tables.

    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.
