Where do you purchase a replacement fan?

Replacement fans are readily available on eBay for $5-15. Just search for: Toshiba CB35 Chromebook Fan
Can anyone explain why the battery needs to be removed? I don’t see how it would interfere with fan removal and replacement.

I was able to replace my fan without removing the battery (skip steps 5-8). Also able to skip steps 12 (Wifi PCB wire) and 13 (headphone jack wire) by carefully moving those wires out of the way while removing the fan. Note that when removing the heat sink, the the old thermal paste should be cleaned off and new paste applied (it may come on the new heat sink). The fan I bought on eBay was a C30 model with different heat sink, but I was able to swap the old heat sink onto the new fan. Final note when reassembling - the rubber footpads are NOT interchangeable. One has a small round hole and the other has a short slot.
