When should I replace my D5 pump? I bought it in 2006. I'm also still running some Panaflo L1A and L1BX fans. Still work like new. I didn't think computer stuff was supposed to last this long? My PSU is 12 years old too, really thinking about getting a new one just because it can't be 100% anymore. Especially after reading Kyles article on the website. I was thinking about getting some used D5s and changing to a dual pump setup?
