I'd say get iStat Pro (I think it's a pay-for now) and see what it's saying for your internal temps.

I guess I am confused as to what is inspiring the question. Whatever the heat increase is, doesn't matter does it ? Given the Crest card comes with the fan already installed it seems like a non issue and thus is not a worry

The extra noise you're hearing - is it at the pitch the fans are running at or is it more of a rumble aka case resonance? A long time ago in another universe I worked for a company that made cooling equipment (fans, air conditioners, etc.) for electronics and racks. Sometimes a customer would say there's a problem with an assembly (noisy) and we'd get it in and power it up and everything was okay. Turns out in a lot of cases it was resonance within the rack and the way the cooling assembly was mounted. Try this if you can: if your cheesegrater is sitting on a hard surface place it on some kind of isolation material like you would put under a monitor speaker and see if the sound diminishes.[

I am pretty sure it is the pitch of the fans, the computer is sitting on a heavy industrial grade carpet and pad, so is somewhat iso from the floor
