Fan speed on ProLiant 3000 Server

The DL380 is a bit more advanced than the Proliant 3000. None of the HP software downloads will allow me to lower thefanspeed through software. However the zener diodes worked great! I cut thefanspeed in half and lowered the noise by 10x, and the temps went up only 5C. I added anotherCPUfanin the rear, this one also running half speed, and now the temps are exactly the same as when the fans were running full speed! Much quieter too! Hi, I think i have the same problem as Fpbear II. I have an old Proliant 800 server that is very loud, it has a 12 V 0.8 A Nidec fan that pushus 130 CFM of air and this is to much for my ears even though i have the server in the closet. Do you think it would work to put a resistor or a Zener diode on my CPU fan? In the 800 model theres are 3 fans, 1 for the PSU, 1 for the system boards (already disconnected this one) and one for the CPUs and harddrives (mentioned above, placed rear in the chassie behind the CPUs). I have tried to replace it but i get a 1611 error so right now i think the way to go is to use resistors or diodes. /Johan |
