SqlCacheDependency leads to lots of queries to my db

Question

I have implemented my own SqlCacheDependency

    public SqlCacheDependency CacheControllerDependency(CacheControllerKeys cacheKey)
    {
        SqlConnection conn = new SqlConnection("connection");
        try
        {

            SqlCommand command = new SqlCommand(
                @"SELECT [CacheName]
,[CacheReloadDate]
,[CacheReloadSource]
FROM [dbo].[CacheController] WHERE CacheName = @CacheName", conn);

            SqlParameter paraCacheName = new SqlParameter("@CacheName", SqlDbType.NVarChar, 100);
            paraCacheName.Value = cacheKey.ToString();
            command.Parameters.Add(paraCacheName);

            SqlCacheDependency dependency = new SqlCacheDependency(command);
            conn.Open();
            command.ExecuteNonQuery();
            return dependency;
        }
        catch (System.Exception ex)
        {
            _log.Error(ex);
            throw;
        }
        finally
        {
            if (conn != null)
            {
                conn.Close();
            }
        }
    }

This works but in profiler I have to much queries (5 per second) for

exec sp_executesql N'SELECT [CacheName]
    ,[CacheReloadDate]
    ,[CacheReloadSource]
    FROM [dbo].[CacheController] WHERE CacheName = @CacheName',N'@CacheName nvarchar(100)',@CacheName=N'MyCacheName'

Is there a setting where I can tell the SqlCacheDependency-System to take it easy a bit? I dont care if my Cache is not up to date for 10min.
