Studio XPS 9100, cpu fan replacement

Jump to solution

My computer has an i7 938 processor. The cpu fan just died and I have ordered a DeepCool Gammaxx 400 replacement. I understand that Dell has a special temperature censor in the original fan and that it controls the fan speed through the bios. How do I re configure the bios so that I do not get a fan failure on startup?

Don't know any 3rd party software that will control the CPU fan in this PC. Most 3rd party software like SpeedFan (free) can't control CPU fans in Dell PCs...

Don't know where you're located, but I see Dell OEM (part number: P281K) CPU fans which fit the Studio XPS 9100 on Amazon, eBay and elsewhere, so shop around for best price, shipping costs, new/used/refurbished and any warranty. The fan by itself shouldn't cost very much, but if it's the fan with heat sink attached, that could get expensive.

The XPS 9000/435T, XPS 730, and XPS 730X apparently all use the same P281K CPU fan so you might try searching for a CPU fan for those model numbers to widen your search.

Please remove your Service Tag from your last post. Never post that tag in an open forum like this. If you got an email from the forum asking for your Service Tag, you need to log in and click the Envelope icon at top right of the page to open your Private Messages mailbox and respond to the request there.

Depending on the how the new fan is wired, it may -or not work at all- when connected to the motherboard connector for the CPU fan.

Assuming the new fan does work, you won't be able to change BIOS to stop it from giving a "fan failure" error every time you boot the PC. You can press F1 after getting the error and the PC should continue to boot, but BIOS won't be able to control the fan's speed based on CPU temps and cooling needs.

If you don't want to press F1 at every boot, you'll have to order a Dell OEM CPU fan.

Thank you very much for you reply. If I can live with pressing F1 after a boot, can I use a third party software to control the fan speed?

I could be misinformed, but I read that Dell no longer supported this computer because it is ten years old. Do they still sell this cpu fan?

Thank you very much Ron. I really appreciate your help. I did find one on ebay and have purchased it.

You're welcome!

Post back and let us know when the new fan is working, and no fan errors! 🙂

The studio XPS 9100 uses a fan mounted on top of a thin disc shaped heat sink, with a cylindrical air duct to take in air from vent hole of side panel.
This is significantly different from XPS 730/730x which uses a tall tower shaped heat sink w/ a fan mounted on its side and a rectangular shroud on top of both. It takes air from chassis and blows air towards back exhaust.  The studio XPS 435MT uses yet another different smaller heat sink fan assembly design quite similar to that in XPS 630i. The only similar point among three HSF designs are LGA1366 socket screw mounting type.  Their motherboard all have Dell generic backplate w/ threaded holes to mount the HSF.  By the way, probably none of these are very good heat sinks compared to aftermarket types. They are probably only good for i7 1st gen at idle. When under load the i7 1st gen consumes a lot of power significantly higher than rated 130W TDP. You are likely to see a substantial cpu temperature rise w/ these heat sink.  Lastly, there is yet another intel stock heat sink fan for i7-980X that works better than the above three but has a terrible cheap and loud fan.
