Fan Replacements for HP xw8400 Workstations

[mavs-fan]

I have several older HP xw8400 Workstations still in use. I wanted to see if there was anything I can do to easily reduce the fan and system noise on these workstations.

The workstations still have their original fans installed in each system. They're each running with 16 gb of ram (8gb x 2). One computer has an SSD and 2 2tb drives. The noisier computer has an SSD (in the bottom fifth bay) and 4 2tb drives.

Please provide links to any recommended parts (and install instructions if possible.).

changing the fans on any workstation or server is not recommended as the installed fans are custom ones that have unique specs and replacement fans may actually cause thermal issues HP does not post the custom fan specs so getting a proper replacement with aftermarket fans is almost impossible

i'v worked on a used both the 6400/8400 systems and they are not that loud

you might want to try using foam backed tape to isolate the fan edges and HD's from the case as sometimes vibration noise is the issue also make sure the default fan speed setting in the bios is at it's lowest setting

I checked the Bios and the power thermal setting was set to the far left. I moved the slider to the right and the fans immediately got louder. The sound was slightly different than what I'm hearing now.

I may try listening to the machine with the case off to determine exactly where the louder sounds are coming from.

I'll also investigate cleaning the fans. I'm assuming they can be easily removed.

Thanks for the tip to try foam backed tape to isolate the fan edges and hard drives to reduce vibration noise.

If anyone else has any other ideas, please let me know.
