The tabletop game Attack Vector: Tactical from 2004 also models the need for radiators and risk of overheating.
Science fiction from the 20th century tended to ignore cooling and cosmic rays (the one exception I can recall is Jerry Pournelle’s superscience Langston Field) and we know these guys are not up to date even on pop culture or good at reading.

The Rolling Stone article is a bit odd (it appears to tell the story of the ex-employee who created Miricult twice, the first time without names and the second naming the accuser) but I trust them that MIRI did pay the accuser. Rolling Stone are a serious news organization which can be sued.
