Hi Python,
Thanks for your response.
Actually both SRX'es weren't optimally placed, both the side-to-side cooled SRX240 and the front-to-back cooled SRX340 get their air from the warm side of the rack, hence the RE temperatures being the same (around 44-45C) (The classic problem with network-interfaces of systems always located at the back of systems, not the front)
The warm side is not that hot by the way, inlet temperature is around 25C if I had to guess.
Can you tell me anything about a healthy temperature for the RE CPU?
The fan-speed is normal, I've seen no alert, but I'm still a bit worried since the CPU temp is over 70C and way higher than that of previous models.
