What is claimed is: 1. A fan docking collar for sealing between a fan housing of a fan and an enclosure, comprising: a pliable body defining an opening for air flow, the body having a seal for mating with the fan housing and a rim for sealing against the enclosures wherein the seal comprises a first annular lip overlapping an interior surface of the fan housing. 2. The fan docking collar of claim 1, wherein the fan can be removed from the enclosure and replaced without compromising the seal between the fan housing and the enclosure. 3. The fan docking collar of claim 1, the seal further comprising a second annular lip overlapping an exterior surface of the fan. 4. The fan docking collar of claim 3, the seal further comprising a groove for receiving an end of the fan housing, the groove being located between the first lip and the second lip. 5. The fan docking collar of claim 1, wherein the pliable body is formed from a thermoplastic elastomer. 6. The fan docking collar of claim 1, the body further having a tapered interior wall bounding the opening to facilitate insertion of the fan into the collar. 7. The fan docking collar of claim 6, wherein the smallest diameter of the opening is located at the seal. 8. The fan docking collar of claim 1, the body further having a peripheral wall for sealing against the enclosure. 9. The fan docking collar of claim 1 wherein the rim seals against an exterior surface of the enclosure. 10. The fan docking collar of claim 1, where the rim seals against an interior surface bounding an opening in the enclosure wall. 11. A fan docking collar for sealing between a fan housing of a fan and an enclosure, comprising: a pliable body comprising a surface, a seal, and a tapered interior wall bounding an opening extending from the surface to the seal, the surface having a rim for sealing against the enclosure, the seal having a first annular lip for sealing against the fan housing, the opening being narrower at the seal than at the surface. 12. The fan docking collar of claim 11, wherein the fan can be removed from the enclosure and replaced without compromising the seal between the fan housing and the enclosure. 13. The fan docking collar of claim 11, wherein the pliable body is formed from a thermoplastic elastomer. 14. The fan docking collar of claim 11, the collar further comprising a peripheral wall for sealing against the enclosure. 15. The fan docking collar of claim 11, the seal further comprising a second annular lip overlapping an exterior surface of the fan housing. 16. The fan docking collar of claim 15, the seal further comprising a groove for receiving and end of the fan housing, the groove being located between the first lip and the second lip.
