If you have purchased an Intel® Boxed Processor, it is likely that the box contained a fan-heatsink. Both the processor and fan-heatsink are covered by the 3-year limited warranty.
If the fan-heatsink fails during the warranty period, you may contact your point of purchase directly or Intel Customer Support for a replacement. To contact Intel Customer Support, please refer to the documentation that accompanied your boxed Intel processor.
If you are looking to uninstall or reinstall a working boxed processor fan-heatsink this document should help:

Some boxed processors, mainly enthusiast processors based on the LGA2011 socket, do not come with a fan-heatsink in the box. Some examples of these are the Intel® Core™ i7-3820, Intel® Core™ i7-3930K, and the Intel® Core™ i7-3960X Extreme Edition Processors.
Intel Corporation does not provide product recommendations, support or components for non-boxed Intel processors (OEM versions). Installation and warranty information for third party fans and heatsinks should be available from that manufacturer.
OEM systems, such as those manufactured by HP*, Dell* and Gateway* may provide a proprietary fan-heatsink solution. Support for those components should come directly from the system manufacturer. To qualify any particular thermal dissipation solution, a processor must remain within the thermal guidelines during operation. If there is a concern as to why a heatsink does not have a dedicated mechanical fan, contact the system manufacturer.
