First thing I would suggest is update the firmware on the blades. Then update the firmware on the enclosure. That should cause the fans to slow down. They are temp based usually.

Update the firmware. It's possible that this will solve your issue.

Ensure all 6 fan bays are populated, the more fans you have the slower each one runs. If you only have 4 fans then stick to the device bay population guidelines - you can only use bays 1,2,5 and 6 with 4 fans in bays 2,4.5 and 6. Reseat the OAs, you can do that live but it really gets loud with no OA fitted.

The fans are usually loud for a reason. Definitely update firmware etc anyway but worth checking the temperature as tihs is often the reason they are running fast.<br />

If they aren't blocked and airflow is good check the ambient temp, and the temp of air coming out of the C3000.

HP C3000 Loud Fans

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
