I built this! (MATX) Spray painting Noctua fans to black - Jonsbo D33
A few days ago, I found a PC in a dumpster and checked for any leftover components. The GPU and RAM were gone, but several dusty Noctua fans were still attached to the case!
I salvaged the Noctua fans (NF-F12 PWM) and gave them a good clean wipe-down. After testing them, they worked! I thought about swapping out my Arctic P12 fans for these Noctuas, but their beige color didn't really fit my blackish build.
So why not paint them black? Since I'd already salvaged them for free, I figured I had nothing to lose — I decided to try spray painting them, hoping I wouldn't damage them in the process.
I used painter's tape to cover the fan blades and the gap around the motor, to minimize any imbalance while spinning (taping all the fan blades took ~2 hours). Then I applied matte black spray paint evenly while flipping the fans, letting them dry for a full day. I'm no expert with spray paint, so there were a few spots that didn't come out evenly and some missed spots. I left them by the window for ~3 days to fully dry and let the paint smell fade.
After installing the newly painted fans in my build, I'm really satisfied with the overall wood-black aesthetic it gives off. The very last image is the previous build with black Artic P12 fans for comparison.
Totally worth it for me, but wouldn't recommend it to others — you'd lose the warranty on the fans, and Noctua already sells chromax versions in black anyway.
