Inspiron 1720 Fan Not Working Unless Speed is Manually Controlled

This question is not answered

Hello,

I have an Inspiron1720 with a fan that isn't working. I've replaced the fan and unforunately that didn't fix the problem. However, I found an application called I8kfanGUI that allows me to manually control the fan speed. When I manually set it, the tool will tell me that it can't change the speed but the fan will instantly start working.


I'm confused and have found no relevant information on this anywhere. Any help would be *greatly* apperciated as it just fell out of warranty a couple months ago.

 

Thanks!

  • First question would be whether the original fan had actually failed - i.e., seized up.  If not, did you test the fan with the Dell diagnostics (F12 at powerup)?  And what happens when you run the diagnostics on the system with the new fan?

    I'm not sure it seized up, I just assumed it had. I've run the first part of the diagnostics test and it stated that there weren't any problems found. I'm running the second half, but it called it a memory test so I'm not sure how viable it'll be.

     

  • Memory test wont help, first you have to run PSA thats pressing FN + power button at the same time, then you go to NO on the prompt of running extended memory test, then you go to test system, then custom test and then fan or you could do the symptom tree and run the fan diagnostics there, if a error message shows up yea probably fan is not working or is not going at the speed it supposed to go :)

  • It wont give me that option. As soon as I end the test it states that there isn't a diagnostics partition available and reboots the rig.

  • okey it seems that you have probably reinstall windows so the partition got erased. if you have  a cd called drivers and utilities, and it says diagnostics boot from that CD and do the same steps that i told you
