Have you tried selecting fan speeds in CMOS setup?  (reboot and press F10)

 

Have you inspected ambient temperature sensor via HWMonitor?

Z800 fans sound is very loud

 

I have two Z800 workstations, both were really quiet when new but they have become noisy over time (about 5 years)

 

I stopped the 2 fans at the back of the case and the two memory fans and the system became almost completely quiet again so I'm sure these are the fans responsible for the noise.

 

I've tried putting a drop of oil into each of these four fans.  This can be done by removing the fans and using a knife to peel the sticker off each fan, under the sticker you can see the well where the oil goes.  It is described here with pictures:

Has anybody else tried this?

 

Has anybody simply tried replacing these four fans and can anybody recommend equivalents?

The fan noise use to bother me however I have since become hard of hearing so the noise does not bother me anymore.

However keep this tread up to date if you find a solution to the fan noise.

Maybe some replacement fans from "Noctula" or "Bequite".
