I have a very noisy fan on my Inspiron 1525. It it the one under the F1 key. I measured it and it seemed to be around 46mm. I ordered what I thought was the correct fan from a seller on Ebay bit it is considerably bigger.
Is there more than one fan installed?
There is only one according to the pictures shown HERE (may have to scroll down). No if you do not order a Dell fan you may get an error message at each boot up as dell system use proprietary fans that have a rpm sense line in them
