Here is the good news: It was in this post (link
) that by Mrlie found there were 5-pin to 4-pin fan cables for sale on eBay (link
) and we didn't have to cut/splice anything like PigLover's method requires. I bought a set also and it arrived at my house. Soon after, PigLover pointed out that they wouldn't work, and Mrlie agreed, and that was the last we heard about it.
Well, I finally opened the package yesterday and started playing around. I realized that it could DEFINITELY work. It's just that two wires were backwards at the 5-pin end! So I swapped them, and the fans spun up with no issues!
The cable on the RIGHT is original as I received it. It is Blue/Black/Red/Yellow
The cable in the center is in the process of being fixed. I used a paperclip to push down the tabs, and pulled out the Black and Yellow cables
The cable on the LEFT (tagged with tape) after re-inserting the wires correctly, it is now Blue/YELLOW/Red/BLACK
And there you have it
