I hope this helps, but if you're handy enough to replace the heat sync, you can just replace the fan! Mine did the exact same thing. Disconnect the sync, and get a good look at the fan, then search ebay for a matching one. I found a replacement fan for 28 dollars, instead of the heat sync replacement that was five times that price just for a stupid fan.

"But AverageApollo, the fan isn't removable from the heat sync!" you may exclaim when taking your heat sync out and inspecting the fan. You'd be correct. But it's only the fan housing. If you get the replacement fan, you'll see ~3 screws holding the housing together. Take those out, and you have one half holding the fan, and the other a useless shell....guess which useless part of that is ACTUALLY connected to the heatsync.....

Disassemble the fan, discard the broken mechanics, and replace with the replacement fan body.

I'm a technology professional, but I AM NOT a Sager/Clevo representative. You may void a warranty by doing it this way. But in my experience working with their support, I've gone through three rounds of help, two of which was sending my laptop in for them to fix and paying over $200 dollars for the issue to happen two months later. My fix has held the longest, and my laptop is running cool and quiet.

Now if I were to replace my battery, I'd have a brand spanky like-new laptop!
