Mark IV w/o fan

[TSM]

Hi guys,

I've recently converted my Mark IV from combo to head but I left it without reverb and fan. Is it safe to run amp without cooling fan?

Pretty tight quarters in a head, and with the tubes upside down, all the heat goes into the pcb. I would install a fan; it's pretty simple.
