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.
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.
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.

I wish there was also a passive test. So we can actually see how that heatsinks on their own performance to gauge the efficiency and quality of the designs themselves. The fans add another variable. Maybe even have a case fan for some airflow. I'd like to see how the heatsink itself does because there can be situations where maybe there is a superior heatsink design here but the company has a poor fan compared to another competitor. The competitors fan could just be superior, thus brute forcing the better temps. How would you really tell? There's no passive test.bug77 - Thursday, May 25, 2017 - link
Hm, why doesn't the article list the weight of these coolers? When they're so large they tend to add quite some torque to the motherboard, so weight should be an important criterion when choosing between these.doyll - Thursday, May 25, 2017 - link
Great testing! TRUE Spirit 140 Direct did exceptionally well for an economy cooler. Would be interesting to see how the TRUE Spirit 140 Power, Archon IB-E X2 and some of the other Thermalright coolers. The PH-TC14S definitely is not a great cooler.fanofanand - Thursday, May 25, 2017 - link
The fact you threw in the Wraith cooler makes me sooooo happy! I was hemming and hawing between 1600 and 1600x with the free cooler thrown in being a nice boost for the 1600. Seeing that the better coolers show a pronounced improvement in most cases tells me that free cooler shouldn't be the decider.Peichen - Thursday, May 25, 2017 - link
Thermalright is like Cooler Master, simple design that reduce cost but performs well. People that have been OCing for the last 20 years know Thermalright's design is usually test provenLeyawiin - Thursday, May 25, 2017 - link
I own two of the original (smooth surface) Thermalright True Spirit 140. Its a very good cooler in many respects save for the fan mounting system. They have the most weak, fiddly wire fan mounts I've ever seen. Plus the rubber anti-vibration pads they were using back then simply won't stay on. I decided with later builds to use Noctua in subsequent builds and even though they're about a quarter to a third more expensive its worth it just for their great mounting system. Plus they regularly send me emails to remind me that all my coolers from them are eligible for free mounting hardware for new sockets. No other company that I know of does that.azrael- - Monday, May 29, 2017 - link
I think that one important aspect of any cooler review should be the *weight* of the cooler.Considering that in most system configurations the motherboard is mounted vertically and coolers are hanging off the motherboard, you really don't want them to be too heavy. Even though the cooler may be securely attached to the motherboard the heavier it is the more stress it exerts on the motherboard. Preferably, I don't want mine to weigh much in excess of 500g.

Quote - Nevertheless, the thermal performance of the NH-U14S is significantly superior as well, especially when the cooler needs to handle a high thermal load.Yes, I realize this thread is three years old, however, having come across it I couldn't let that blatantly wrong observation from the review go uncontested when the reviews own results CLEARLY show the Thermalright True Spirit Direct 140 having a lower overall rise over ambient than any of the other three coolers.
How do you figure the Noctua has better performance if your own results show that the Thermalright does? Why did NOBODY notice that, and comment on it?
If Crashman or Garrett over at TH had done that, they'd have been ripped to pieces.

I just read TH’s Best Coolers for 2022 article and the first one in the list is a Cooler Master that fails against the competition in every metric, according to the data in the site’s own reviews.
