The heatsink in the ps3 is set up in a great way that makes it easy to clean... at least that is mho from looking at the pics online.
There is that famous youtube video where a japanese program dissasembled a launch unit, not sure if there are online guides though.
Harder than a hooker on nickel night, can you pls elaborate.
Not as easy as it might seem I'm afraid...
I opened up my PS3 over a year ago to do some cleaning and it can get daunting fairly quickly; the problem is that you have to physically disconnect essentially everything - connectors as well as physical components - in order to get to the fan, which is on the reverse of the system and not immediately exposed when you remove the top slipcase.
For myself, from the limited dust build up relative to what I expected that seemed to be the case at the time, as well as my increasing trepidation at disconnecting the BD drive connections and handling the unit itself, I backed away from the project.
I can assemble a computer fairly quickly and am fine with any/every number of PC parts, but some of the proprietary connectors and the manner in which the components are so super-tightly spaced/placed gave me pause in terms of my hopes of a 100% system rebuild... and anything less than 100% would have been fairly disappointing for some efforts against dust.
Robert I'd go with some low-level vacuuming and hope for the best if I were you!
