There are really two issues: tube life and room comfort. To assure long tube life, you need to have at least a foot of clearance above the amp for ventilation. I remove the top plate from the amp when in use for extended periods. This helps the amp run cooler, extends tube life and improves the sonics. Next, I have two very quiet ceiling fans. Works well enough.
I live in New Orleans and we have an expression: It's not the heat, it's the stupidity. (There are other expressions like a 12 step program consists of two six packs of Dixie.) You learn down here to simply accept that there's going to be some exposure to tropical weather. Rather than suffer emotionally we simply eat, drink, enjoy music, take it slow, wear light cotton clothing and shower a couple times a day. Keep 'em glowing and have yourself a party!
