Review on 🌬️ upHere 140mm RGB LED PC Cooling Fan 5-Pack - Ultra Quiet High Airflow for PC Cases with Remote Control - RGB143-5 by Duke Ballard

I have 2 of these case fans working in a phanteks enthoo pro 2 build, one for the intake (front bottom) and one for the exhaust (rear top) combined with 2 CORSAIR 140mm Radiators as front intake fan and 6 120mm case fans as intake (bottom) and exhaust (top). These 140mm fans replaced the 2 120mm fans I had in the same places, so I can only speak of a performance difference when 2 large fans are installed instead of 120mm fans. Pros: • Constant fan power at 1000 RPM, which is fairly quiet • Max CFM is about 10% lower than more expensive Corsair products at a fraction of the cost ($9 per fan vs $45 for Corsair - 500% price difference for 10 % performance difference RGB colors are vibrant and have many different settings and configurations, hundreds more than Corsair software controlled fans Poor • Overall build quality compared to the Corsir fans I have is slightly cheaper (Corsairs are bulkier and use thicker plastic for their case) • You can't control fan speed and have to use the included Uphere controller for RGB • Product support is lackluster if one breaks (no guarantees other than Amazon's return policy) Bottom line: Like someone with a case , which has enough room for airflow, these fans look great when finished and cost a fraction of the price it of their competitors. Each person will need to look at their personal build to see if these fans are right for them as someone may want to control the fan speed or use them to cool the AIO. However, for the price, they do the job of a passive fan and look pretty decent doing it!
