I have done a couple of searches on this matter and haven't found an answer, so I thought I would post it. Has anyone compared the cooling and noise of a Delta FFB0812SHE at 7v with an SLK-800 against say a Mechatronics 53 cfm/39 db or Sunon 50 cfm/40 db? I will be using this as a backup for my watercooling.
