ThermalRight TY-143 SQ – Test and Review

Back in the days I had the chance to test and review one of most powerful 140mm fans worldwide – the TY-143 offered by Thermalright. A fan which was used as dual setup in one of the most massive and productive coolers on the market – Silver Arrow IB-E Extreme. The fan demonstrated serious cooling capabilities and for that reason I am pretty excited to check what its square version TY-143 SQ has to offer.

For this test and review I received the square Thermalright TY-143 SQ version, which was provided to me in the typical for the series pretty simple carton package made entirely of recycled paper with the company logo accompanied by the model name, the revolutions per minute range and a see through cut, through which we can see the propeller colour on the front panel.

On the back side of the package there is a glimpse of information regarding the technologies used so this fan can be created, the warranty period, information regarding the additional accessories and the major operational details.

So, let’s put the package aside and check the structure of the fan.


Thermalright TY-143 SQ STRUCTURE

And this is a view of the fan outside of its package.

Thermalright TY-143 SQ is equipped with a pretty solid and at the same time very simple looking square plastic frame, entirely in dark red colour with dimensions of 140 x 140 x 25mm featuring 4 mounting holes on each side to be used when installing the fan on a 125 x 125mm screw hole pattern case fan slot, CPU cooler heat sink or water cooling radiators. The frame itself does not feature any noise dampening material to block any noise generated from vibrations.

The propeller of Thermalright TY-143 SQ is produced with seven very wide and at the same time not very sharply angled, bright orange blades designed according to the Thermalright’s silent torpedo blades technology. According to the company, this technology should provide the most quiet operation and efficient airflow level.

And last but not least, the connection between the frame and the propeller is done by two ball bearings, which should guarantee consistent and stable revolutions per minute and longer life span of up to 50.000 hours. The motor of the fan is PWM powered and regulated by not very long, sleeved in black mesh 4 pin cable and connector for optimal automatic control of the performance/silence balance when connected to 4pin PWM fan header on any motherboard.

With this motor, the fan itself is capable to operate at 600 – 2.500 revolutions per minute, delivering airflow level range of 54 – 221 m³/h with noise level range of 21 – 45dBA.

The quality and the origin of the product, like every product in Thermalright portfolio, is guaranteed by a company sticker on the back of the stater.



According to the information described on the back of the package there should be 4 metal screws, 4 anti-vibration mounts and 1 4pin Molex adapter. Unfortunately this test sample arrived to me with absolutely no additional accessories. Not that they are the most important thing in the world but still they will definitely be needed and I really wonder what happened with mine.

I believe the time to check how Thermalright TY-143 performs has arrived.


Thermalright TY-143 SQ TESTS

The tests will be conducted in my standard way. I will install the fan and test it at 5V/7V/9V/12V and my goal will be to check the performance of the product in real conditions. It will be tested under close-to-perfect conditions, not taking into account any external factors. The results achieved during the tests can in no way be the same if the models are mounted on a cooler or on the case fan slot of any modern computer case. I will measure the amount of air going through the fan for one hour and its speed. For this I use a fan controller, a voltage meter, an anemometer and a stand made specifically for this purpose.

And this is what the fan looks like installed on my test stand:

The test results are shown in the following charts:

Airflow through the fan at 5V, 7V, 9V, 12V

Propeller rpm during the tests at 5V, 7V, 9V, 12V.

The anemometer showed the following air speed passing through the propeller:

After mounting the fan onto the stand, and leaving it to run for about 60 minutes at full speed, it was time for the tests to begin.

As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and Thermalright TY-143 SQ made at least one full revolution at about 3V. To do the first test I had to increase the operating voltage to 5V.

Through the first test conducted at exactly 5V:

  1. TY-143 SQ was rotating at stable 1230 revolutions per minute, providing airflow level of 100.32 cubic meters per hour

At this test the fan was just a bit noisy

At the second test conducted at exactly 7V,

  1. The fan was rotating at 1725 revolutions per minute, delivering stable airflow of 138.24 cubic meters per hour

At this test the product became really noisy.

At the third test conducted at 9V, 

  1. TY-143 SQ was rotating at 2160 revolutions per minute, delivering stable airflow of 179.52 cubic meters per hour

At these revolutions per minute the fan was really loud.

At the last test conducted at 12V, the fan reached its maximum performance:

  1. TY-143 SQ was rotating at 2595 revolutions per minute, delivering stable airflow of 216.96 cubic meters per hour

At this test I was able to hear the fan working from the next room. It was a hell of a loud.


Thermalright TY-143 SQ Conclusions

1. Thermalright TY-143 SQ Performance:

Before I express my opinion regarding the square version of TY-143, I would like to mention that the original model is one of my favorite fans on the market since I am a big fan of fast, loud and very potent fans. Models, which I can use during the cold days at very low speed and at the same time use them during hot days at higher speeds. In both cases these fans will definitely do the job and will keep my rig cool and stable. Of course, throughout the hotter days the noise level will be higher but my PC will feel comfortable and I will feel safe without the need to find other ways to keep my machine cool.

Anyway, TY-143 SQ is a model which entirely fits in my idea about a good fan and for that reason I find it a very appealing product.

The fan is made to work at wider revolutions per minute range, which according to ThermalRight is meant to fit both as a case fan or as a CPU cooling unit inside every modern and compatible with 140mm fans case but still I wouldn’t really say it is the perfect choice for a case fan. This model is made for brutal cooling performance and specifically to keep high grade processors working stable, cool and reliable at overclocked or even extremely overclocked frequencies, while being cooled by a massive twin tower CPU heat sink or water cooling setup.

This fan is definitely a performer. Yes, a pretty loud one, but still when performance is demanded, the noise level could be sacrificed. And since this is a fast pace product, the noise level is significant. At low revolutions per minute it is, let’s say, decent if you are not a silence junky, but at high revolutions per minute the noise level is really serious. This fan is definitely not an option if someone decides to use it inside his HTPC rig, while watching movies on the big screen or browsing the web. But if someone decided to chase a high FPS in games or overclocking results – hell, yeah! ThermalRight TY-143 or TY-143 SQ will be the best choice.


2. Thermalright TY-143 SQ Appearance:

Thermalright TY-143 SQ offers very attractive colour scheme featuring dark red square frame combined with bright orange propeller. Colour scheme, which I find really appealing and is definitely an eye catcher if the fan is inside an entirely in black case. And since these days most of the hardware companies are focused on RGB features the fan can definitely be a nice addition to cases with black/red or orange background.

I think Thermalright TY-143 SQ deserves the following reward:



Thermalright TY-143 SQ has been added to the 140mm catalogue.

Official price (MSRP): Thermalright TY-143 SQ  – unknown

Warranty: 24 months

I thank Thermalright for the test sample.
