A month ago, one of my Noctua 140mm radiator fans stopped spinning out of the blue. I tossed it, in my box of dead electronics and moved on, until I recently became irritated by the Corsair fans I've been using, prompting me to check up on the possibility of a replacement. I wasn't expecting this response.
I contacted the company via email with a screenshot of my receipt from Amazon and 13 minutes later, they replied.
I was so impressed. Good for you, Noctua. A $27 fan, replaced without question. 13 minute response and product shipped the next day. You couldn't ask for better service. Outstanding.
I will, without a doubt remain a long time loyal customer. Posted this simply because I was impressed by how quickly they're handling this. If you're considering a company that backs its products up, consider Noctua.
