Review on 🔌 Enhance Fan Control: 4Pin PWM to 3Pin Standard Fan Adapter Cable (4 Pack) by Victor Anderson

On the right is a standard 4-pin PWM socket. Left is what I got from Coolerguys. Note that the plastic tab on the right is much thinner than the left. This conforms to specification and is correct. The one on the left is out of spec and therefore will not mate with a standard 4 pin PWM connector. This is so wrong it's just ridiculous. I bet Coolerguys got a deal for a million pieces of junk from a cheap Chinese manufacturer and didn't bother to inspect them upon receipt.
