I have been having some issues with the temperature of my Ceton infiniTV 4, and wanted to keep an eye on them over time, so I created an application that checks the temp and reports it to a windows performance counter every 10 seconds. I found it very useful, so I decided to release it to everyone. The application and source are available on Google Code. I haven't created any documentation on it, but it should be relatively easy to use. .Net 4.0 is required, and it must be run as Administrator to set everything up. Just run it, make sure your tuner's IP address is in the text box, install the service, then start the service. At that point, you should be able to go to the windows performance monitor (perfmon.exe) and add the counters. The thing I like most about using performance counters is that you can set up performance monitor to record the current value every X (seconds, minutes, hours, etc) and have a record of your temp over time. This has allowed me to see what changing fans, ducting, etc. really does to the temp, not just at a given moment, but graphed over time.
