The fans are at 100% from the profile I put on it and it still goes to about 85C and crashes the machine. It's the original fans, they're working fine, but a huge amount of piping hot worryingly smelly air blasts out of it. It's in pretty spacious air in a 25C room. It does receive a bit of hot air from a nearby GPU, but not much. Not sure why it's so hot. It seems happy at 2/3rds clock and is now sitting just below 80C.
