M4300-24X - multiple sudden restarts


Has anyone got confirmation that heat is the cause of restarting the switch ?

Did replacing a factory installed PSU help ?

I`m having restarts quite often - twice a day or one restart in 2-3 days. The restarting unit is the backup one, (the restarting unit is allways the warmer one). It becomes unstable when reaching 64-65C. The fans duty levels are constant and I haven`t seen it changing above 27%,(mboard about 5200 rpm, PSU 4600 rpm), but the switch is burning up.

I`m running the latest firmware upgraded from (the restarts were also before the upgrade)
