Sorry for the late post, but I have a quick fix. You just need a dremel like tool and some scissors. There are 4 connectors on the adapter but only 2 are required. I just cut it in half to get rid of that. After you’re left with 2 connectors, use a dremil on the open side where the connectors are. Just make a small enough incision to give breathing room for second connector (black wire in my case). After that the connectors should be a tight squeeze but just push it on the bottom row of pins(right 2 pin, not the left) on the HDD. My fans have been running at a quiet speed for the last hour. See the attached photos and feel free to ask any questions. Instructions are a bit confusing but photos should help show what I did. Side note: Grey wire should be on the top once the drive is installed.
