AMD does not publish specifications for their bundled coolers that I could find.

The Spire and Stealth are very similar, the Spire uses a 100mm fan, the Stealth is 90mm. Both are 4-pin PWM. The heatsinks are aluminum and differ mainly by height. (previous version of Spire had a copper insert)
Both of these coolers have minimal heat dissipation capability and should not be used on processors greater than 65W TDP.
