Cleaning fan on back of spindle motor

[mbm]

Hey guys on my lb15 i noticed on the back of the spindle drive motor I have a fan, I took the screen off and cleaned everything best i could but not gettin good air flow still. Hard to see if theres a intake/exhaust grate anywhere else but im sure there has to be. Any suggestions?

Does the fan rotor turn freely? Many will turn at lower than normal rpm's due to bearings etc.

Actually when i cleaned all the crud out I must of packed some in between the blade and motor housing. Blowed everything out real good and it picked and ran correctly. Learn something everyday thanks!
