It's interesting that the RM564B HAS a fan. My 564B doesn't have a fan, and a check of the 564 manual doesn't show a fan, even though it's full of hollow state heat sources. I guess I should keep in mind that rack mounted devices could not expect the open air ventilation that bench/cart mount scopes could expect. I wonder if Tek automatically added a fan to every rack mount device that had a power dissipation over some threshold.
Is your Rotron fan a 115 VAC fan? If so, It should be easy to find a replacement.
