I was in the server room and all of a sudden I hear the server fans speed up and get loud. I saw no error lights. I logged into the server and everything was fine. I looked at the logs and I saw a couple 7 entries on event viewer>system logs.

I have seen these error one in a while not all the time. What is this? Is this the reason why the fans sped up as it happen during that time?

"The IPMI device driver attempted to communicate with the IPMI BMC device during normal operation. However the communication failed due to a timeout. You can increase the timeouts associated with the IPMI device driver."

Update firmware on the R510 to the latest firmware.

Check you are running the latest drivers on the Host OS.

Check cooling in the datacentre.

Check their are no obstructions to air flow.

Fans can also speed up, if the system, is under stress, high CPU etc

I would check with Dell support.
