Fan Speed Changes?
Our Vostro 230 (4+yrs) changes fan speed for short bursts when 1st started, then it's normal? It has been cleaned inside...and if it was CPU temp, it wouldn't stop (I would surmise). Thanks for anything!

Thanks for anything! Normal. It will run it through the various speeds as a test on initial start up, then once the system is fully booted it turns control over to the thermistor and programmed steps. -- Steve W. |

It just started doing that...so it's puzzling. As long as it doesn't rev constantly I won't worry about it. Thanks! |

Change anything in the BIOS (that you know of)? CMOS battery ok? -- Steve W. |

The fan was running fast today for longer than it has...about 15 seconds. The HDD temps are around 82 deg at present. |

Fan Speed Changes?
The HDD temps are around 82 deg at present.
I would be worried if 82 degrees celsius. It's way too hot (as a reference, my hds are running at 32 and 33c) Is there any fan, inside, that stopped working ? |

Thanks for anything! Normal, if it is only one sustained burst. Typical of systems with LGA775 and newer Intel CPUs. Built into the POST to make sure the fan is running properly. Tries to rev the fan to the max RPM. The 4th wire on the newer CPU cooling fans provides something of a tachometer reading... Ben Myers |

Ben Myers Update: I recently did some maintenance on this PC: Cleaned and re-applied compound on the CPU heatsink; Cleaned fans; new HDD and re-intall W7. It will still hi rev the cabinet fan (not CPU) when you wake it? Other than that, it performs well. Any thoughts? Thanks! |
