nope

well mine wasnt !
i also ran mine with 1 x10 inch fan for 2 years just have to keep an eye on the guage and switch heaters on full when it starts to rise too much to be on safe side,but am going over to twin fans this winter ,
you can also fit a fan switch off a cossie and a lower temperature opening thermostat to keep temps down.


one other thing though mate ,i think you might struggle to get polished/shiny fans to match in with your bling !!!!
