RP-1/RO/RSS Express install: Part overheating in Mercury orbit

[Fragile-Engineering]

Hi there,

With my latest RP-1//RO/RSS installation I have problems with overheating (and exploding) parts when in an orbit around mercury. I know it's hot there... but even with parts that are labeled to  be 2000Kelvin heat-resistant, this happens. I have put a thermometer to the vessel and this reads out around 750K on the sunny side of mercury and 25K on the dark side. So these are values I would have expected, but why do my parts with 1024K and 2000K heat-tolerance explode anyway? Radiators do not seem to help here. Also putting everything into a fairing (for sun protection) has no effect on the overheating. Am I missing something or is this simply a bug? Any ideas?

best regards

Michael

Do you have system heat installed?

Many parts have internal temperature tolerances much lower than their skin temperatures and 750K is very hot for a lot of them. Which parts in particular are exploding?
