Hi,
Don't know if this is the right section for this question, I hope so.
I have access to small server machine, an HP Proliant ML110 G4, that is having an issue with fan speeds: the CPU and rear fans are running at full speed, which is not only bad for their longevity but also they are generating a LOT of noise.
The first thing I did, I took some time, removed the chassis rear fan, removed the CPU heat sink and fan, disassembled it all, and made a proper cleanup of everything, so all fans and heat sink are now completely dust free.
Still the problem with the fans continue: every time I restart the server, somewhere during windows startup, the fans jump on to full speed. I've made a series of tests for starting up, and I found that the problem seems to be with the network connection, because ...
... if I start the computer with the network cable disconnected, it starts correctly and the fans run at normal speed. After the startup is complete, I wait for a couple of minutes, making the time for services to startup, and the disk activity led shows that everything is up and running at normal pace.
Only then I connect the network cable, and 5-10 seconds latter, the fans start running like hell! There's no apparent reason for that ... there is no heavy processing going on, and the fans start running at high speed just a few seconds after I simply connect the network cable.
So do you have any ideas of what may be causing this fan problem?
Could it be a bad network cable (but the cable is in a place for so many time, without anyone even touching it to bring problems now)?
Could it be a faulty network card?
Additionally and as a side note, when the computer starts from cold boot (after reconnecting the power cable), I get a warning stating that the BIOS settings will be the default ones. I suspect that this has something to do with the CR2032 lithium battery, which is still the original one and so it may be out of power by now, and I'll be replacing it shortly.
Could it be possible the problem comes from the lithium battery not storing the BIOS settings (uhm ... seems a bit ridiculous as I'm typing this possibility
)?
Any opinion/suggestion counts, as this problem is really puzzling me.
Thanks
