Hello, I just upgraded my Xserve 3,1 to the W5590 3.32 Xeon processors on Mojave. They seem to work fine, however one thing I notice is that the fans seem to go full blast after installing these CPU's. I read this is 'normal' in the MacPro if the CPU tray is wrong or only a single CPU installed. I installed Macs Fan Control to try to control them, however I was able to only control 4 of the 5 fans. Temperature according to Macs Fan Control shows the temperatures under 50C which is what I had before the upgrade. However it is fan no 4 which is the uncontrollable one via Macs Fan Control, and that fan only blows on the memory. Anyone know of any tricks to fix this via software? I only have problems controlling IN4 and OUT4, and I'd hate to have to run with my older Xeons to keep this thing quiet. The Xserve really isn't that loud when the fans are on low, but when the fans (even only one pair) are at 4000 - 4500 RPM, this thing screams. I posted a note on Git Hub too, just curious if people on here have problems too.
