As I was fed up with my K6 CPU fan noise I adapted a "silent" Socket 462 one (Arctic Cooling Copper Lite I had around since 15 years)...quite some filing on the edges to give some clearances for the capacitors but it works well!
GPU fan is the next in line...
This is my take on cooling solutions now as well. I'm not afraid to damage the cooler if it allows me to jury rig a quieter solution.
I also like giant passive coolers for video cards that wrap around the back. It can free up the adjacent PCI slot and there is usually plenty of room towards the CPU zone of the case to tape a low RPM Noctua fan to it.
On that note... is there a reliable and easy way to get 12v fans to run slower? I have a huge box full of new old stock basic Socket 5\7\370 CPU coolers with nice YS Tech fans on them, and they work extremely well but they spin at an excessively high RPM for the low wattage CPUs they are cooling.
One thing I tried was using a 4 pin molex to 3 pin fan adapter that allowed me to pull the molex pins and swap the 12v and 5v. Doing this brought the fan speed down considerably, but one time I noticed that the fan actually hadn't started spinning, so I'm thinking that 5v is just too low... which is too bad, because it is otherwise a dead-simple and dirt cheap method of making these things much quieter. I have read about swapping the ground and the 5v pin on a molex 4pin to get 7v out of the 12v line, but I'm pretty sure I experienced some strangeness on one system doing this. I wish I could remember what happened now, but I just remember not liking what it was doing.
I'll admit, I'm not good with understanding voltages and how a power supply works, but it to me it seems sketchy to connect two rails together in a way that may not be intended. Just doesn't seem right.
I would love to be able to wire in a super simple resistor solution or something but I'm not sure if I could do that reliably enough and I'm not paying $8 per adapter for ones on ebay. I didn't spend anywhere near that much on the coolers themselves.
Now for some blitting from the back buffer.
