A decent switch mode will be RF quiet. It's also a lot smaller, lighter, a lot quieter and use much less electricity. I use a Mydel MP30SWIV. 

I used to have a Manson EP925 Linear PSU and the fan was as noisy as hell on it and it weighed a ton.

Tested mine (PSW 30H ) against a linear and a car battery for rf noise and am satisfied there are no issues. To test it properly would have involved getting or loaning a spectrum analyser which would have cost me. The My Del MP30SWIV has pretty good reviews and is worth looking into (wish I had known about this on at the time ). MLS are selling them at a very reasonable price. Worth checking out and may myself as a backup or make the one I'm using now a backup. Back in the late 80's  early 90's a lot of switch mode psu's very noisy but have improved over the years.
