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.

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

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.

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.

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.

Chris,

Thanks. I'll keep checking back here, hopefully there's a fix. I haven't tried restoring to factory defaults(ctrl+f11 on boot up). I wonder if this will work...

chris,

do your fans rev to 100% for 1-2 secs or does it rev to 100% until the computer loads the desktop?

when i first received my computer, when i bootup the system, the fans would rev to 100% for 1-2 secs and then drop to normal(almost no sound). this is all while the system still has the black screen with the windows logo and load bar on screen. i am failry confident that you know what i am describing.

for whatever reason, the computer now has its fans running at 100% once I press the power button. it remains that way until the desktop is loaded.

i hope you are not telling me this is normal. because if it was, it would've done this the FIRST time i used my computer. if this is normal it would be doing the same thing on my xps 630 and 730 computers i have at work.

here's a link to a youtube video i found of someone experiencing the same problems as i am.

i don't know how this could possibly be passed off as being normal.

as mentioned in the comments section of the video, the fans should only rev up for 1-2 seconds upon bootup.
