Size of TempDB Microsoft SQL Server 2005 Are there drawbacks to having a large tempdb in a SQL Server database? Assuming the disk is not full. 

I am creating large temporary tables in a couple of queries. Once I am finished running queries, I drop the temporary tables. However, tempdb remains relatively large. Should I be worried about any subsequent problems with the server? Such as performance, or something I am not able to think of.
Tempdb will be recreated if the server is restarted and at that time tempdb will be reset size wise to initial size settings. In the meantime once the temporary tables are dropped space will free in the data files but size on disk will remain the same.

I wouldn't however worry about the size unless you have space issues.  Next time you run queries that use tempdb a lot you will save on growth operations and get a bit of a boost to performance since it will use the above mentioned free space in the data files
