I followed a written build guide to connect all my case fans, but one just wouldn't spin no matter what. After freaking out and almost returning the fan, I noticed the guide's picture showed the cable plugged into a different header on the board. I had it in the pump header instead of the fan slot! Switching it over made everything work perfectly.
I go to the PC build class at the library. They always show guides with expensive parts. Think that's a bad fit for here. Most people in my area have limited cash. For example, my friend needed a basic setup. I used a guide for a budget build under $600. It runs all his programs fine. The class should include more affordable options.
Honestly, trying to route those stiff IDE cables around the case was a huge pain. Modern builds with thin SATA cables are cleaner, but that old struggle taught me to plan my entire cable route before screwing anything in.
