Review on 💡 SilverStone FX500-G: High-Efficiency 500W Flex-ATX Power Supply with 80 Plus Gold Certification by Justin Dorsett

This is about the only 500W flexible power supply you'll find, so I'm grateful for that. But the fan is unbearably loud with a very high pitched screech. I knew about this while working on the SFF build, but it was really unbearable. I ended up opening up the PSU and hooking up a linear potentiometer to one of the fan wires which is on the outside of the case so I now have a knob to manually decrease the fan speed. I considered replacing the fan with a quieter one, but it's a 15mm thick high-speed fan. 20mm won't fit, but 10mm leaves a gap and doesn't let enough air through. The potentiometer solution works fine, but it will most likely void your warranty and is somewhat dangerous if you don't know what you're doing. But like I said, this is pretty much your only option, so tread carefully.
