Re: ThinkCentre M58 - Fan speeds constantly 100%

Tried that on one of the systems I had that was having loud fan issues, worked like a charm.  Will be testing on other systems as well.  I would've thought that I had done all of these things but would seem that this particular procedure, which I did step by step as written, worked for this one system.

I've tried this too with no effect.

Re: ThinkCentre M58 - Fan speeds constantly 100%

     I have had a few that are still persistent, and still have to replace the motherboard, but it is a good step to try before moving forward in that direction.  I have had it where it worked for a little while, after a few reboots or so the loud fan is back and its time to replace the motherboard.  I have had it work once or twice out of maybe ten to fifteen times.  I have one currently that is in that has the loud fan, I reset the cmos as the steps listed and it booted up nicely, mouse keyboard didn't work, moved those around on the back, now they do, restarted, fan back to being loud.  Unique stuff, but motherboard related for the most part.

Re: ThinkCentre M58 - Fan speeds constantly 100%

I have about three to five thousand.  I don't have the stats for the amount of motherboards replaced for issues with fans.  You might be able to check into the amount of motherboards replaced through the eclaim process.

Re: ThinkCentre M58 - Fan speeds constantly 100%

I just fixed a loud fan issue which was a bad stick of ram.  I have two more loud fan issues in that I'm looking into and will update you on the outcome.

Re: ThinkCentre M58 - Fan speeds constantly 100%

Gave Kudos to the engineering tip - has helped on two cases today, just have one more loud fan issue to go, and will see how long those pcs that I did the engineering tip helped for.  Gave Kudos to Jamez as the tip has helped every now and then and it is a good tip to try before replacing anything. 

 

  1. Power down system
  2. Remove power cord (power cable from PSU to AC) from power supply.
  3. Clear CMOS jumper in item #17
  4. Remove battery in item #25
  5. Hold power button for 5 seconds
  6. Replace power cord (power cable from PSU to AC)
  7. Power On then hold Power again to Power off
  8. Connect CMOS jumper back on Pin 1 & 2
  9. Replace the battery in item #25
  10. Power up (system beep twice)
  11. Press F1 for BIOS
  12. Set default to the BIOS
  13. Set time and date
  14. Press F10 to save BIOS settings
  15. Check if Fan is running at 100%

check that the thermal sense cable is plugged into the system board. We had replaced a system board for a video issue and the cable was laying under some other cables and the tech missed plugging it back in. Once it was plugged in the high speed fan issue was solved.

 

The connector plugs into the system board close to the main power connector.


Thank you! Problem solved.

Re: ThinkCentre M58 - Fan speeds constantly 100%

Well, sometimes we all do something stupid, but this one is so dumb, I though it bears passing on.  I bought an M57 tower for my TV-recorder PC.  Found out the hard way Thinkcentres won't run with the new Radeon 5xxxx video cards. I have to have the Radeon card with true HDMI output to solve the problem of TV sound being out of sync. with people mouths when using sound cards or built in audio. So, I found a parts only M58 mother board on E-bay for cheap and decided to try and upgrade my box.  This all went well until.. well, no luck with the 5xxxx card, but there is pure joy with a no-name Radeon 4570 PCI Exp. v2.0 card... Until the fan won't shut up.  I had to buy a 6-pin temp. sensor, did the procedure to reset the CMOS.. Still found the case FAN at 100%, I can't stand the noise.

 

The M58 tower motherboard, i.e. 9965-A2U has two fan connectors.  The one on the edge of the board near the SATA is not the correct one.  The "system fan" connection is next to the battery.

 

All is well now, and I'm happy with my Thinkcentre once again.
