How do I stop Dell R730xd fans from going full speed when Broadcom/QLogic NetXtreme 57711 PCI card added?

I have a pair of Broadcom NetXtreme 57711 10GbE cards. I put one in a Dell R710; it boots with the card fine, the OS (CentOS 7) recognizes it, and all seems well. However, when I put the other card in an R730xd (also running CentOS), something…

How do I lubricate a noisy fan?

I have a case fan that can be quite noisy. I can take the fan out of the case, peel back the sticker on the center to expose access to the bearings, and lubricate the fan. Thus far, I've been using a few drops of WD-40, but after a few days the fan…

Linux programme to show me how much the fans are running?

I can use lm_sensors to tell me the tempature of various things on my laptop. And sometimes I can hear the fans starting up. Is there anything that will show me how fast various fans on my system are spinning?

Are there general guidelines for fan configuration/capacity for operating at altitude?

Background: The server I'm configuring needs to be able to work at altitudes up to 10,000 feet. Are there any rules of thumb or guidelines on how much faster fans have to spin at altitude (due to lower air density) to provide adequate cooling? Or…

HP DL380G6: Where is the Temp. Sensor #29 (System Zone)?

The Temp. Sensor #29 of my HP DL380G6 seems to give me a wrong number. It says that the temperature is more than 50C (Caution: 60C, Critical: 65C) while the actual value is 13C. And I think it may be the reason why all fans run madly at 78% of the…

Dell PowerEdge R220 fan speed high when idle, low under stress

A few days ago we got two new PowerEdge R220 servers. One is fine but the second one displays bizarre behaviour: If there's minimal load or network activity the fans spin at full speed. However once it's stressed or receives lots of network traffic…

The title is telling, I guess. In particular, I am wondering how risky is it not to change the fan of a 4 years old Supermicro server?
