See, now this is exactly the kind of thing that I would get. Not because I need it. Not because it helps keep the RAM cool. No. Just because. That's why.
Except that it apparently isn't even done correctly. Fans wear out. Fans are noisy. Fans are absolute crap and I generally hate them, but they look neat and in some cases they actually do something useful. The problem here is that these apparently run all the time. I can guarantee that as soon as I bought this, within a week, a fan would start whining loudly and be hideous. Why would you make the fans run all the time? FFS put a temperature sensor on it so it's off until needed. Maybe make it spin just for fun for a couple minutes each day. But don't kill the fan early by running it when it isn't needed. That's just dumb.
And yes, as an earlier poster said, it would have been nice to see at least some testing showing temperature with fans off vs fans on. We all suspect the results to be almost identical, but confirmation would be useful.
