how to take apart these fans?

I still have these 80mm coolermaster led fans (r82).

They are now noisy and dirty, and the thing with this is sealed ang area where you could remove those O rings to detach the fan blades. kinsay kibaw unsaon pag tangx2 ani? i need to lubricate these things.

btw are the R5s also like this? sealed ang front with a plastic thing?

tang tangon nimo ng cover sa top nga naay name? pero hinay hinay lang kay basin mag gisi pag detach. after ana ma open na nimo naa na syay lock na ring type either plastic type or metal gamiti ug tweezer para dili ma deform... nya push nimo ang kanang murag pin... ana lang or pwede nimo diritso ug oil...pero dapat dili ordenaryo nga oil kay para mo langtod gyud...

just be careful not to loose the snap ring which locks your fan blades in place. good luck!
