Noctua is one of few companies that has not broken my trust (yet). They promise me a really good fan, they're ten toes in on the promise and they have yet to fail to deliver.
They have many dedicated fans, both mechanical and biological.
Yeah, their products are expensive but every one of them proved high quality and reliable.
My fan broke after five? years of near 24/7 use. Customer support was very easy to reach. They sent me a new one after I sent some serial numbers as proof. They asked me then to break off a blade, and a picture of it so I didn't have to sent it back.
