WOW! Thank you SO much for helping me with my 5690. Back in September 2004, when it was brand-new, it's idle temp was around 46 degrees celsius. Since then the temp has come up to the point where just booting it up brought the temp to 64 degrees celsius. It started overheating VERY badly whenever I played Battlefield 2142 (go figure) and the fans were ALWAYS running at full blast. When I saw this thread I was a little reluctant to open up my computer and started wet-sanding components (!), but after following the instructions to a 'T', it has brought my laptop's temperature down BELOW the levels from when it was brand-new (41 degrees celsius at idle). There was TONS of dust caked up inside of it and I shudder to think of how much shorter its life span is because I didn't do it sooner, but I'm very happy that it's done now and I'll be opening it up more often for cleaning and an annual Arctic Silver application. It's like it's brand-new again! Thank you.
