John what fan did you finally chose?
Does any one know of a rack fan that runs as low as 30db?
Some Mfr don't list the specs.
Thanks,
Mark

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.

Mark, This is the fan I have settled on, for now. It is two speed, and I find that low speed works fine, though I have no specs on this fan. I have tried other fans using a variable speed control. However, as of now I using the clip on fan from Holmes, fixed, no oscillation. It's pretty quiet, and I don't have to deal with that AC slider switch, which was pretty hairy. It also does a very good job of cooling the VAC. Cheers, John |
