I have a system that has no fans except for the ones in my PSU. It's started to get a bit noisier and there's kinda a bit of rattling that's started from the fan. I live in India so I thought it might be the dust or something of the kind but I checked it out and haven't found any source for the noise. As such I've decided I'll just buy one now instead of waiting till later since, my dad is coming soon to India soon and can bring me a PSU. I'm looking for something that's 200 Watts or higher at the very least since it's a low power system with passive cooling and a ~65 watt CPU. 300 watts or higher is even better since I could potentially reuse it for another build in the future that has a GPU. I'm looking for something preferably silent and less than 50$. Thanks.
