XPS 730 FANS AT 100%

Hey all, this is my second post regarding my xps 730 fans running at 100%. My first post had no replies. I know this issue has come up alot, especially for the xps 630. It's just getting really frustrating because I have no idea what to do. It also dosen't help that most of the posts here are for the xps 630, with the ESA updates, BIOS updates etc etc. I have no idea if they are compatible with my xps 730.

 

Anyway, I'm hoping someone can respond with some help. I'm hoping Chris might have a solution.

Here's a rundown of what's happened and what I've tried.

Whenever I turn on my computer the fans start at 100%(sounds like a vacuum). I open the Nvidia control panel > performance > chassis, under "CREATE", I uncheck the 'automatic fan' option and adjust accordingly. I choose to save as 'FAN1' and choose that profile to start when system is started. Once I restart the computer, the fans remain at 100%.

I've also tried adjusted the other profiles that were availble, USERDFLT and OSBOOT(names may not be exact). No dice. There's also a SYSDEFAULT profile that appears when I try saving a new profile, but I don't know how to make changes to it.

I've tried uninstalling the software, reinstalling. NO GO. Tried powering computer off, removing power cable, holding power button for 10secs, power computer back on. SAMETHING!! =(

 

On a side note, everything was working fine for the first 2 weeks when I received my computer. I'm sad to say this all started when I was trying to adjust the LED lights(turn them off).

 

Sorry for the long post, I'm sure I've missed some things. It's just really frustrating and I know some people here must be in the same boat as me. Please help!

Re: XPS 730 FANS AT 100%

bigwatch,

Reset the XPS 730 Master I/O board
* Power the PC off
* Open the case cover <ADMIN NOTE: Broken link has been removed from this post by Dell>
* Look for the Master Control board <ADMIN NOTE: Broken link has been removed from this post by Dell>  underneath the PCI Card Cage and Front CPU fan assemblies
* There is a blue plastic jumper. Is it on both pins or just one pin?

Chris,

 

I won't be infront of my computer until later today. How do I reset the XPS 730 Master I/O board?

Also, if the blue plastic jumper is on one pin, what does it mean? If the jumper is on both pins... what does it mean? And what would I do?

 

I have an XPS 630 infront of me that I can break. Would resetting the Master I/O board be the same for both the 630 and 730? I want to try with the 630, just so I know how to do it when I am infront of my computer later today.

Re: XPS 730 FANS AT 100%

The 630 is too different. Here are the 730 instructions.

* Power the PC off
* Open the case cover  <ADMIN NOTE: Broken link has been removed from this post by Dell>
* Look for the Master Control board underneath the PCI Card Cage and Front CPU fan assemblies
* There is a blue plastic jumper on pins 2 and 3
* Place the jumper on pins 1 and 2
* Power the PC on, then off
* Place the jumper back on pins 2 and 3
* Replace the cover
* Power the PC on

Re: XPS 730 FANS AT 100%

Chris,

 

I will try those steps when I get home. Do those steps usually resolve the issue for the fan speed on the xps 730? Hopefully it does because I don't hear too many problems regarding fan speed other than on the xps 630.

 

I also tried calling Dell xps tech support. The one guy I spoke to said he's never had a call about an issue with fan speed before. He advised to update the bios from the support site. I beleive the one available to download is 1.0.3. I have 1.0.2(?). Will updating the bios fix this issue too? Is this something I should do anyway, if doing the jumper thing resolves the issue?

 

Thanks.

bigwatch,

Load bios 1.0.3 to keep up to date.

Fixes and Enhancements
1. Regress hard drive/optical drive boot sequence in both normal mode and RAID modes.
2. Ensure audio and 1394 works correctly after power management events.
3. Fixed AMD graphic card error message issue.

Re: XPS 730 FANS AT 100%

Chris,

 

I tried the steps that you've given me but it made no changes. It looks like the fans go at 100% once I boot the computer on. Once it loads the desktop, it reverts to a profile that I chose, which lowers the fan speeds. I don't know what else I can do. I was thinking that it might be a default profile that loads during system startup but I can't find any such profile.

 

Please advise.

Re: XPS 730 FANS AT 100%

bigwatch,

Now I am confused. In your first post you stated the fans were always at 100. Now, they slow down when you load a profile. That is how mine reacts. 100 on boot, lower once a profile loads. I guess I do not understand what you want the fans to do??

Chris,

 

Sorry for the confusion. The fans run at 100% as soon as I power on the computer, it will remain like that until my desktop appears on screen. At which point, one of my profiles will load and lower the fan speeds.

 

When I first received my computer, whenever I power on the computer, the fans run really fast for 1-2 secs and then go down to a lower rate(even before the desktop loads). It no longer does that.

 

I hope this clears up the confusion.

Re: XPS 730 FANS AT 100%

Any suggestions on trying to get my system fans to rev for 1-2 secs upon bootup(the way most xps' do) rather then revving at 100% until the desktop appears?
