Fans significantly more aggressive with ROS7

Tue Jan 18, 2022 9:35 pm

Upgraded my CRS328-24P-4S+ from 6.48.x to 7.1.1 - I have noticed that since the upgrade the fans are now almost constantly running at highest(?) speed where as before they were mostly inaudible. Being such small fans they very noisy at these levels. Is there any way to temper the fan curve a bit?

After reading the title I thought that this thread was about @anav getting more aggressive than usual :)

Seems there is no way, except putting your switch to colder area. In your case, it looks like tigger is sfp+ module. Can you try to cool down somehow this module?
Also is strange my CPU is on 58C and fans are on 0 RPM, but I'm still on ROS6.
