Corsair ML140 PRO RGB vs Thermalright TL-B12: Comparison
Corsair ML140 PRO RGB vs Thermalright TL-B12 static pressure compared
Static pressure is where these two genuinely part company, Corsair ML140 PRO RGB 1.27 mmH2O against Thermalright TL-B12 2.87 mmH2O, a 56% lead for Thermalright TL-B12. Airflow runs the same way, 55.4 CFM on the Corsair ML140 PRO RGB versus 69 CFM on the Thermalright TL-B12, another win for Thermalright TL-B12. Add max speed to that, 1200 RPM on the Corsair ML140 PRO RGB versus 2150 RPM on the Thermalright TL-B12, and the pattern holds. Lighting is not the same on both, RGB on the Corsair ML140 PRO RGB versus No RGB on the Thermalright TL-B12. There is a split on fan thickness as well, 25 mm on the Corsair ML140 PRO RGB versus 25.6 mm on the Thermalright TL-B12.
Which should you buy, Corsair ML140 PRO RGB or Thermalright TL-B12?
The Corsair ML140 PRO RGB is the one to take for quiet RGB case airflow and builders who dislike loud RGB fans, though it is not built for thick radiator duty (insufficient static pressure) and Maximum-CFM case airflow. Buy the Thermalright TL-B12 for budget builds that specifically want no RGB and filtered intake or radiator duty on a budget, though it is the wrong buy for showcase builds wanting lighting and ultra-quiet-first priorities. Our rating of the Corsair ML140 PRO RGB (8/10): A quiet, glowing 140mm fan best suited to case airflow rather than radiator duty. Our rating of the Thermalright TL-B12 (8/10): excellent value for a non-RGB static-pressure fan, undercutting pricier options with little real performance loss.
