Review on Super Silent Blue LED 120mm PC Case Fans 💙 - High Airflow Cooling for Desktops by CONISY (3 Pcs) by Nico Ramdeen

Bought 4 pieces for my wife's computer; which we use 24/7 for bitcoin mining (with 2 GPUs). She wanted it to look beautiful while it was being dismantled. Their system's total power consumption increased by 15 watts with these fans at full power (where I live it costs 2 cents a day at full power 24/7), cheap for how good they look! Fans blow air in the right direction. Some reviews said they blow in the wrong direction. Even if it is "true", turn the fan around the ding-dong, screw holes on both sides in the same place. When mining 2 GPUs with 4 fans installed, my CPU liquid cooler temperature dropped by 2.5 degrees Celsius. The temperature of the processor dropped by 5 degrees. Both GPUs dropped 5 degrees. My motherboard's temperature also dropped 10 degrees and my hard drives each dropped 10 degrees. These fans do their job really well and I can barely hear them. My CPU liquid cooling fans are louder, as are the GPU fans. The only negative review I read that made sense was the guy/girl/helicopter who said that if you overtighten the bolts the bolt holes will break. That's right. The first one I tried to screw in broke. But it doesn't matter, the screw is still there, like the other three, so the fan will certainly not stir. I didn't try to drive the rest of the screws with Superman; so I didn't break any after the first one. These fans rule. I recommend anyone who has 2-3 cents a day to run it on their PC.
