Replace HP ML50p generation 8 fans by more quite Noctua A14 PWM

Hello all,

I bought an hp ml350p generation 8 serverwith 2 cpu processors  to using it in my home.

As the server is designed for farm server location use it makes a very loud noise as a jet turbine noise. You certainly know what I am talking about.

As it is not possible for me to use it in such condition of noise. I bought some quiet fans from noctua http://noctua.at/fr/nf-a14-pwm/specification  (up to 1500 rpm and about 80 CFM). I was encouraged by these thread where it was working on generation 6 : https://greghunter1968.wordpress.com/2016/05/15/quiet-ml350-g6-it-is-possible/

Unfortunately, after replacing the old fans with noctua fans, although the fans were spinning the bios was detecting a fan failure at boot and restart after that :

fan 1 ailure detected

fan 2 failure detected

fan 3 failure detected

fan 4 failure detected

Fan Solution Not Sufficient

Do you have any idea what could be the problem ? Is there any possiblitity to disable fans error in bios ?

Here is the specs of the old fan : https://www.digikey.com/product-detail/en/delta-electronics/PFR0912XHE-SP00/603-1707-ND/3078695

and for FAQ about Noctua fans : http://noctua.at/en/support/faq/general-faqs/category/Fans 

Many thanks
