Broke the HD sensor connector installing an HD, Will this harm mac?

After helping many people upgrade their Mac Minis HDs, Memory, and other things, I decided to put an SSD in my Mac Mini. While removing the HD temp sensor plug (clip) the whole thing broke broke off the Sata daughter card that holds the HD and optical drive. Will it hurt my mac mini to run with the fan on full tilt? I use this as a server in a closet so the sound is not bothersome. If it is bad to run it this way, where can I find that daughtercard for a reasonable price to fix this. Thank you for your help!
