Ventilation - let your system breathe...
I have no idea of the actual statistics in this case, but here is my theory. Component failure is in many ways a function of time x heat.
The more heat, the lower the durability.
This is especially relevant in tube components, but in others too.
I now have a computer fan at the back of my preamp. The preamp sits in a rather crowded place, in my shelf, and does not quite have the minimal distance of free air above it. This fix cost me $50 or so including some resistors so I could tune the fan down to totally silent operation. Works very well. Better safe than sorry.
