You can persist, but if it is to be permanent, in my opinion it is better to use an LSA connector of the appropriate category. Unless you have some idea of disconnecting this connection, then it`s a `dice`.

"like in a sauna" is a bit of a relative concept... contrary to appearances, it is a bit difficult to determine the temperature "by feel" and you can be very wrong. ;)
Just connect the switch, hang a thermometer near the equipment and observe what happens. I have installed various "home" equipment in attics, including uninsulated metal roofing tiles, and they work fine. As a rule, the operating range of all devices is wider than the parameters. However, it can be taken into account that the life of the device may be shortened in such conditions.
But it`s worth checking the temperature.

It is enough to cause air movement near the housing (underpressure/overpressure) to remove the heated air coming out of the housing. This can improve circulation inside the housing, and therefore the efficiency of heat dissipation inside, and ultimately improve the working conditions of the electronics inside the housing. This is a somewhat distant analogy to a fan built into a housing.
