💪 Efficient 3pin Power to 4pin Molex Adapter: Enhance Connectivity and Versatility Review

I was skeptical about purchasing this as it's so hard to find a very good product. It really works with my fan controller! I bought a PCI fan to plug into the vertical slots next to my CPU, but it always ran at full power since it ran Molex. I connected it to my fan controller and now I can actually switch it to different speeds! No more whining if you want.

Many of us PC builders prefer to connect case fans to the motherboard headers rather than directly to the PSU Molex connectors. The problem is that many case fans only come with 2-wire Molex connectors. This adapter lets you do just that. While the 2-wire fan doesn't allow for RPM tracking due to the lack of a tach wire, it allows the BIOS to control fan speed through voltage regulation if the BIOS is designed for it. I always have a few on hand.

One of these was delivered in great condition so arrived quickly. The adapter was exactly as shown in the picture (2 wires with a 4-pin molex socket and a 3-pin fan socket) - the cable length was 11 inches, so there was no routing problem in my case. I recently bought a new case with an integrated fan control box that uses a 3-pin fan. Connectors - I had a 200mm case fan with a Molex connector that I wanted to install on the side panel. Didn't want to connect the fan directly to the PSU (didn't
