hey im going to be replacing my current coolermaster fans with faster fans, im just wondering if the Scythe SlipStream Fan 1900rpm is a good idea as they will need to be placed upside down in a horizontal position for my top rad in a pull configuration?
These fans will be on a fan controller so noise shouldn't be a problem until i start benchmarking.

Has anyone had any problems with these fans in the past?

thanks,
