No idea really but tube amps are shedding considerable heat. I think that in the vacuum atmosphere of a vacuum tube normal room temperatures don't affect the tubes operation all that much if any. Your fan set-up will cool the chassis and components but one can't guess how uniform or effective that will be. I make sure all my tube equipment is not enclosed in any cabinet, just too much heat for electronic components.
Best temperature for optimum tube performance
Is there an optimum temperature range in which tubes perform best?
I've been running tube amps/preamps for over 40 years and have always placed a small, quiet fan in front of them to prevent excessive heat build-up (a modified, two-door antique silver cabinet is where they reside).
I'm aware that electrical resistance increases in proportion to increasing temperature, but am I somehow decreasing the optimum performance of my tube components with this strategy?
