To warm up or not to warm up, and...?


So I bought one of those AC Infinity component coolers for my big fat receiver, and have been using it, and it definitely keeps it cool. But I've been wondering this... If a component performs better when it has warmed up, then should one use such a device as this AC Infinity that I now have, or would performance be better without it? Or perhaps there is a certain temperature I should let it get up to for best sound, or just keep it as cold as it will? I'm so confused now. Lol. Please help... Thank you!

If you’re not actually hearing a negative impact in sound/presentation with your ears: don’t let it bother your head.      iow: Relax and enjoy!
no doubt heat is an enemy of components and most mechanical and electrical devices

but introducing another motorized component to drive and power fan cooling also has negatives in noise and vibration

guess all in all ymmv... 
How does AC destroy your sound, exactly? So far I've noticed only improved sound. Plus, I run all components through a Monster Component Power Conditioner, and I can tell you there is no hum, hiss, or anything else, even at high volumes... in musical pauses. My only question is if I should let the temperature get higher than the 77 degrees I have it set on? Thanks for any input!
