One of my good clients wanted a way for him to have a secondary way to monitor his server heat. He has a place that is less than reliable and although they provide monitoring services, he still would like his own. I did some research and I told him that he should think about getting a Temperature@lert USB Temperature Monitor. That way he has a second way of checking the temperature. Also, the system is built so that it can send out emails to any email (including to your phone) to warn you if there is a concern.
