Scythe Kaze Flex 120 RGB PWM Fan Review 2

Scythe Kaze Flex 120 RGB PWM Fan Review

Packaging & Accessories »


The Scythe brand has been known to TechPowerUp readers for a while now, especially if they have read our excellent CPU cooler reviews where Scythe tends to offer good products with bang-for-your-buck value. My first interaction with the brand was via their co-branded Gentle Typhoon fans: made by Nidec-Servo and licensed to be sold by Scythe around the world until it was not. It led to other resellers coming up with options to replace what was then regarded the best static pressure optimized fan for PC watercooling, be it in the form of their own Gentle Typhoon fans or making new fans altogether. This was a while back, however, and Scythe has been working on their own fans since. Today, we take a look at one of them, the Kaze Flex 120 RGB that aims to follow their cooler product philosophy as well. Thanks to them for providing review samples to TechPowerUp!

As the name suggests, this is an update on their Kaze Flex fans with an RGB implementation for customers wanting it. There are three models under this name: the SU1225FD12LR-RDP, SU1225FD12MR-RHP, and SU1225FD12HR-RNP. They are differentiated by their rated speed (800, 1200, and 1800 RPM respectively). I was sent the 1200 RPM fans, which in hindsight was something I should have checked for to request the 1800 RPM fans instead, but this does tell us what the manufacturer believes is the popular fan/product more often than not. As with the Alphacool Eiszyklon Aurora LT RGB fan we saw earlier, the Scythe Kaze Flex 120 RGB fan (1200 RPM model) appears to target a similar audience prioritizing noise over pure performance, and with some RGB lighting to boot. The European market is particular about this relative to most of the Americas and Asia, so it will be interesting to see how these two fans go up against each other as well.
