Cooler Master Sickleflow 140 V2 ArGB Square Frame Fan, ArGB 3-Pin Customizable Leds, Air Balance Curve Blade, Sealed Bearing,140mm Pwm Control For Computer Case & Liquid Radiator

These fans are awesome as starter fans. If you are building a PC for the first time and are looking for some low cost fans that have customizable RGB features then look no further. They are much better then any cheap knock-offs that you'd find from companies like UpHere. Don't waste your money on knock-offs, buy these instead...HOWEVER! If you are an experienced PC Builder either looking to upgrade your rig or possibly build something a bit more robust then your first build, I wouldn't purchase these fans. They don't rattle or anything, but they do have fan noise. ie, you can hear wind blowing which can be annoying for some. For some people that's not a big deal. and for most first time builders it probably wouldn't even be severely noticeable or would just seem like the nature of how PC fans work. But if you go from something like a Corsair LL series fan to these, you'll for sure notice the difference.Keep in mind that if you buy those Corsair LL fans instead of these your wallet will also notice the difference. So you are very much getting what you pay for here. You're getting decent fans that are good at cooling, don't rattle (or at least shouldn't), and have some cool ARGB effects available to them. But if you are really trying to level up your rig, then by buying these you'll have a sick looking rig with good airflow, and with nice RGB, but also more wind sound coming from it then you might want. Just depends how much that matters to you or what your goals are.

These fans are amazingly quiet. They keep my GPU/CPU so cool it is crazy quiet. I used to play 4K with a lot of noise from my 2080ti sitting at around 55c-67c. Felt like a 747 at my desk. It was very loud. I had to adjust my GPU fan curve just to keep it under 70c. Now? Hahaha. My GPU fans are on silent, I don't even hear them and i'm below 52c; majority of times i'm at 48c playing video games in 4k. What a difference! This is crazy! I have no regrets in the purchase or the pre-order. I have yet to setup the RGB as I need a few more things to get it working; cooling wise though these fans are amazing. Worth every penny I paid for them. They are Super Quiet and they will keep your case Super Cool to enjoy 4K gaming in peace.

Si bien cuentan con RGB addressable (ARGB) es decir que cada led se ilumina individualmente, pudiendo así, crear efectos interesantes y más llamativos (se nota mucho en el efecto rainbow por ejemplo), creo que la decisión de ponerlos todos en el rotor le quitan vistosidad, aunque la relación calidad - precio está presente, no hacen tanto ruido pero tampoco son los más silenciosos.

Es buen producto y cumple con los necesario. En particular lo ocupe ya qué por un incidente una de las aspas de un disipador Hyper T2 se daño y pues busque opciones ya qué hay pocas de esta medida y cumplió sin problemas. Igual qué el original.

I need 3 thing from the case fans.1st - bring the temperature down - 5 star,2nd - noise level - 4 star,3rd - Look nice - 3 starWith 6 of them in my case, they are very noisy above 1300 rpm. But they do not need to run that fast. My Ryzen CPU and RTX 3080 are stable at 67c when these fans are running around 1000 rpm. Adjust the fan speed in your bios.
