c7000 Fan Noise

[Harrison Duong]

I'm running a c7000 but notice the fan noise in zone 1 to be significantly louder then the other zones. I have 13 blade servers in the enclosure with 10 fans. They are not running at very high utilization. When checking the temperature of the servers in zone 1, there is not much difference from servers in other zones. The fans in zone 1 run at 72% while the other 3 zones run at 32-37%. Anybody else run into this issue? The ILo firmware is 1.8 and power management controller firmware is 3.4.
