Montech AX140 PWM Fan Review

The Montech AX140 PWM costs 15 dollars, making it one of the most affordable 140mm ARGB fans. According to its maker, it is suitable for chassis or cooling system use, meaning that its airflow and static pressure are high enough to cover both usage scenarios. This is something that I will confirm (or not) in this review. 

The Montech AX140 PWM costs 15 dollars, so it is one of the most affordable 140mm fans that you will find in today’s market. Its 120mm sibling, the AX120 PWM, is currently sold at 13 dollars, which is also a highly affordable price for a 120mm RGB fan. The main features of the AX140PWM include a rifle bearing (Montech claims to be an HDB one), a 4-pin PWM header for easier control of the fan’s speed, and a three-year warranty. You should not be extra picky at this price range, but throughout the review, you will find out if this fan is worth even the 15-dollar price tag or if you better pay a bit more to get a better product.
