Running a fan to cool amplifier any ill effects?

I have two mono blocks....VAC 140's and have installed whisper fans above the transformer(s) housing. The fans aren't directly blowing on the 8 300B tubes...but they will be running cooler as air will be circulating around them. I installed the fans because the metal housing would become hot(125deg+ I would guess)and I personaly would prefer to cool it down. Kevin Hayes says this is normal for that amp. Do tubes need the heat to perform better or is some cooling ok...and have no effect?? on the sound quality. I am looking for some informed opinions....any would be appreciated.

Also the air will not enter the vents so no dust will deposit inside the amplifiers.

if the tubes run slightly cooler this may extend their life a little.

I would be more concerned about the electrical noise the fans motors could be dumping into the mains. If you have a different circuit for the hifi or conditioning of some sort you could be ok. As long as the fan motors are good quality it may not a problem anyway. Lets face it many amps use fans internally.

Can you hear the fans in your listening room?
