Yo, Thai boy. Singapore boy here. I think I can answer you.
You guys australia have a dry heat - its 30C 90% humidity here in
the jungle southeast Asia. Do you know how messed up that kind of humidity is? I’m not a scientist but basically it’s like swimming to work everyday (scientifically).
The BBC thinks there’s places we haven’t explored yet but they just don’t realise when humidity gets to 101% we go from jungle to swamp, so they get a bit lost when that happens.
Anyway I haven’t noticed the V throttle because of ambient temperature - sometimes when i connect my egpu and the V is tucked in the space between the egpu and the monitor then maybe there’s something - but then again, it’s also in a tight space with poor airflow and two much bigger things just farting hot air on it.
Could also be it’s the cpu having trouble keeping up with the gpu, or maybe the hub-in-a-hub-in-a-hub thing I’ve got going isn’t what usb 3 was meant for and it’s just the cpu going ‘hey man, wtf?’
But yeah. Don’t stick your V in [an oven/ your pants/ under the stairs] and the weather shouldn’t even be a concern.
