Yesterday, I noticed my notebook fan on my dv7-1135nr was a bit noisy and my warranty just ran out, go figure. Was going to take a look at it, just in case something worked itself loose, but I balked on taking it apart since you have to basically disassemble the entire computer to get to it. Great design!!
Anyhow, I eventually decided to order a spare in case it goes kaput. My initial search pulled up a dv7 service manual that suggests the AMD version of the series takes a different fan (488885-001) than the Intel version (480481-001).
However, I'm not aware of an Intel version of the dv7-1135nr and the HP web site part finder gives me the model # that the service manual suggested was for the Intel version.
Should I assume that the 480481-001 is the one for me?

If You don't want to clean manually Your laptop from dust etc. use for that compressed air such as this and clean out all the vents with it. Laptop must be switched off and without battery pluged in it.
Minimum once per year I always recommend manual clean of heat sink and fan. (I know then this will take some time and many parts must be pull off, but You will feel the difference believe me.) This would be the best solution for You I think. If You will do it then check Your bearing of fan. If it's bad You must replace it with new part.
How to do it check Your service documentation here (On page 96. I know that You have it, but I always write all informations. There is alwys chance then someone with the same model will be looking for this information). Remember about puting new paste on components.
About this situation with part number. I must say then it's an interesting mystery for me too, but answer may be simple then fans for AMD were having poor quality.
I've checked just a few minutes ago many AMD and Intel models and all of them were listed with only this purt number fan model.

Thank you for your response. My only concern with the AMD vs Intel fan is that the connector and/or expected wattage may be different.
I am hoping someone has had to replace this fan and can express their thoughts or experiences.

The part was in fact a 480481-001.
Other part #s were
The ball bearing seems fine, although its still noisy. Unsure what to do. Could have loosened up just enough to be off-balance when I'm using the notebook? Not sure. Guess I should just find a replacement.
