This follows up on the review of the Thermalright TY-141A SQ earlier this month. I had mentioned coverage of the faster TY-143, now in square frame mode too, and here it is. So without more delay, let’s thank Thermalright again for the review sample and get right at it.

Let’s take a look at the specs from the product page:

  • Fan Dimension : L140 mm x H140 mm x W25 mm
  • Fan Weight : 190 g
  • Fan Speed : 600 – 2500 RPM (PWM)
  • Sound Level : 22 – 48 dBA
  • Airflow : 29.54 – 123.05 CFM

Also, because it is an apt comparison to be made, let us also take a look at the specs of the round frame TY-143:

  • Fan Dimension : L152 mm x H140 mm x W26.5 mm
  • Fan Weight : 170 g
  • Fan Speed : 600 – 2500 rpm (PWM)
  • Sound Level : 21 – 45 dB(A)
  • Airflow : 31.4 – 130 CFM

Once again, we see that the square frame version occupies a smaller footprint and yet weighs more due to the large amount of frame here. As with the slower TY-147A, the round frame version seems to have better airflow at lower noise levels. They both use the same PWM controlled motor, and rotor with their so-called Enhanced Hyper-Flow Bearing (EHFB) which could just be a long life sleeve bearing for all I know as no other details are provided. The TY-143 SQ carries a 2 year warranty which does not inspire confidence in longevity but for what it is worth I have not heard of the round frame version going bad easily either.

Community member Doyll comes through yet again with another detailed technical drawing of the TY-143 SQ (and also the TY-147A SQ) as well as demonstrating the physical differences between the round and square frame versions:

As you can see, it’s a bit more than simply swapping out frames and there are several subtle changes as well. Let’s take a better look at the fan now on the next page.
