Or buy quite fans ?
Mate its not about buying a “Quiet” fan.. its about those fans you get that clog themselves up with shit and dust and make a loud noise because there not spinning correctly or sticking
My northbridge on me download PC is a coolermaster and gfx is a errmm something I dont know.. It sits on the floor and collects loads of dust and it started to clogg up and make a noise like some mass serial killer scraping a hook along a wall ..
Anyhoos
Removal of Fans, an application or 6 of Sprayduster and a squeeze here and there of sewing machine oil… and their spining as normal
