I moved my Dell motherboard into a new case along with some other equipment. I don't want to use the factory 3 pin female plug case fan because I am now using 5 rgb 12/5v 5 pin fans as my case fans. They run off of a controller powered by Sata and I can change speeds via remote control. The factory fan is plugged into the right 3 pins on a 4 pin plug on my motherboard. If I leave that fan unplugged, my computer will shut down in less than 8 hours because it is not getting feedback from that fan. Now I have 2 fans double stacked which I hope is short term. I also want to replace my factory cpu fan with an aftermarket cooler with a 120mm fan to match the other 5, and plug it into the rgb/fan controller. I assume my computer will also shut down to protect itself when it sees a lack of feedback from the cpu fan port. This is an old school mother board with the old school bios. I do not see an option in the bios to disable either of these fans. Is there a non complicated way to run without them, such as an adapter of some sort?
