Super-heated gases collect up in the ceiling and spread out, which is why with no fire near it something up there like that fan get damaged like that a good distance from the actual flames. Notice how black the fan is but isn't seared or charred, that's heavy particle accumulation from the hot smoke that gathered up high.
