await 的 Task，有什么区别？

Test1Async() 和 Test2Async() ，在Main()方法里都可以正常异步调用。两个方法有什么区别？

static void Main(string[] args)
{
    Console.WriteLine("Hello World!");
    Test1Async();
    Console.WriteLine("Call TestAsync1 OK!");
    Test2Async();
    Console.WriteLine("Call TestAsync2 OK!");
    Console.Read();
}

public async static void Test1Async()
{
    await Task.Run(() =>
    {
        System.Threading.Thread.Sleep(5 * 1000);
        Console.WriteLine("TestAsync1 OK!");
    });
}

public static void Test2Async()
{
    Task.Run(() =>
    {
        System.Threading.Thread.Sleep(5 * 1000);
        Console.WriteLine("TestAsync2 OK!");
    });
}
