those are pretty normal temps for a 6610, especially in slightly warmer ambient temperatures, and reason #32423 I tell people to not try to put even SLOWER fans in these things. My stack in a rack in a 75f room are sitting at 73c
I totally get that these things run hot, the weird thing to me is how the temp increases when I plug in the power supply 1 and only leave power supply 2 plugged in. I keep running show chassis and you can literally see it creeping up quickly until the fans kick on full blast and cool it down to 71 degrees and then starts the process all over. Once I unplug power supply 1, it sticks around 71.5 to 73 degrees and I never hear the fans kick into full speed.
Lastly, I tried what Wolfstar suggested in a post above and pulled out the entire power supply 1, and the temps dropped to 66.5! Maybe it's because it has some additional open area to allow for cooler air to get in? How can I check and see if the power supply is actually bad? I want to try and get some money back from the seller if that is the case. I'm fine without the redundancy if I can just continue to run the switch on a single power supply.
Also the power supply 1 I pulled is a rev B if that makes a difference. I am gonna pull the other power supply tomorrow to make sure it is a rev B as well unless there is a way to do that through the CLI.
