OK all U RIO BASHERS!
I have been using RIO pumps for as long as I have been watercooling.
My first one was a RIO 800 I think, BIG SUCKER! HIGH VOLUME, it still works today, been about 3 years in service.
Now I use the small RIO 400 that DTEK puts in there system. It rattles a bit, but supergluing the impeller tot he shaft takes care of that. I have been running this pump nonstop for about 8 months now. No problems at all!
I love the rio pumps, I will not buy any other.
That is my $.000000000 cents
