As of writing the combined download count of the GPU Thermal Monitor has hit 520 :)
So far I'm yet to receive any major feedback on bugs etc which leads me to believe it: a) works perfectly or b) no-one is bothering to report issues. As I'm an optimist I'm going with option a :)
I've had more requests for remote monitoring of the GPU temperature via a simple http request. This is something I need myself in order to keep track of temperatures in remote machines. This is now built in and in testing and bug fixing, hopefully to be released soon. I've not used completion ports as they seemed like overkill for what should be a light traffic application but as the source is included and under creative commons license please feel free to add them if needed. Secondly having it open source allows for some code review, which is important for security reasons as it now allows remote connections.
If you have found a bug or would like another feature added please drop me a comment or email.
