What is your need for silence? Are you going to be using this in a recording environment with open microphones? If so, there are all kinds of solutions such as isolation by segregation or distance, a replacement low-noise fan in either the amp or the computer, or a virtual amp that John describes. As you probably know, there are standalone amp and speaker emulators available as footpedals or rackmount devices that have a 100-plus dB noise floor. None but the most discriminating ear can hear the difference, if any.

Please tell us more about your situation and needs so you we can advise you more fully. I guarantee that someone here has a solution.
