New build on 11/17/18. X470 Taichi, Ryzen 2700X stock spire CPU cooler. All working perfectly since build until yesterday. Computer won't boot. All RGB comes on ram/case fans etc. CPU cooler fan will not spin. Switched CPU fan to water pump fan connector still nothing. Switched to Chassis/water pump connect fan runs and comp boots. Case fans run when plugged into CPU header no problem. I have cleared the CMOS checked all connectors. Any ideas what my problem is? First build in 10 years so i'm not very savvy on diagnosis. Thanks for any help in advance.

You might need to breadboard the system but until then, we await your followup post.

Thank You for the Response. Apologies I was not aware of that. Here are the specs.I flashed to the latest Bios via Asrocks site. The problem still persists. As stated the 3 pin case fans will run off the CPU Fan header just fine. My 4 pin Spire cooler fan only runs on the water pump header. Obviously the CPU header has power. Any help is appreciated.
