There's one circumstance when you can know for sure whether to follow up or not: when there are instructions in the job posting. If there are clear directions to reach out to the hiring manager (or if there are instructions not to), you should definitely go with the employer's preference. Otherwise, you just need to use your best judgment.
Generally, you should be confident that your cover letter and resume are strong enough to catch an employer's attention without the need for additional communication from you. However, if you feel like following up shows your enthusiasm for the job (and you can do it politely in a way that doesn't come across as desperate), then go for it. If you do decide to initiate additional communication, follow tried-and-true advice to make sure you do it successfully.
