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.

Try to prevent the fans from touching the chassis .
The fans could induce a low level vibration and a subsonic that the Amp will carry. Perhaps making your amp work harder.
If you can, put the fans on a stand blowing on the Amp.
