Chassis fan replaced

The old chassis fan was a 8 cm, no-name, noisy s*cker…I mean bl*wer. Replaced it with a 12 cm, dust proof and silent AcoustiFan. It was a bit too big too fit, but with some violence and some straps instead of bolts, it works beautifully! In normal mode, I can’t hear it! But that might be the power supply that drows it. Next thing to rip out of the tower is that power supply. Hopefully, I will get the new one next week!
The PC – about one year old – is a HP Pavillion, and I will NEVER buy a PC out of the box from a ”major” brand in the future! Too much components are of bad quality, no downloadable drivers etc. Better to build one myself.
