I'm using a Volcano 9+ and it works great with my 1900+. I'm usually 41 celsius idle and 45 full load. My old CPU fan used to keep it at 59 celsius idle and 60+ full load.
I'd sorta worry about the company, though.
http://www.resellerratings.com has them as a pretty poor company. Their returns and tech support services have really, really low scores (like 3 out of 10). It looks like they have damn good prices, but if it comes broke, you're probably screwed.
