Fans on SR2625URLXR speeds up to full speed for 3 seconds then slows down

[JWolf1]

Hello everyone,

We have a server that normally the fans run at normal speed, however recently the machine has been speeding the fans up to full speed in 3 second bursts then slows them back down. This just started and the computer is close to 3 years old. I brought up the Intel Active System Console and it doesn't show any problems. Does anyone know what might be causing the fans to speed up? I am going to clean the inside of the computer this weekend but looking inside it doesn't look like it is very dirty, and I would expect that to speed up slightly, but not go up to full speed like it is doing. If there is a heat sensor or speed sensor on a fan intermittent, would that cause this behavior?

Thanks for any suggestions,

John Wolf

Can you look at the System Event Log (SEL) and see if it is reporting any voltage, power, or temperature issue?

Hello Dan,

Is there any way to look at that without bringing down the server? It doesn't appear the sel viewer can be installed on a running Windows Server 2008 system.

I have looked in the Active System Console, and it is not showing anything in there. I have set it up to send me emails when it logs anything and I have not received any emails either.

Thanks,

John
