Fans tricked into overworking when anything done in Eclipse [message #1770501]

I'm using Windows 7 64-bit edition on AMD hardware and everything is fairly cool in my rig. However, whenever I open Eclipse, my CPU fan goes into overdrive and starts cooling my CPU until I stop doing something with Eclipse. After I stop doing anything involving Eclipse, it stops spinning as hard soon after. I recently reapplied thermal paste to my CPU and checked to see if any hardware was failing (it wasn't). This is a pure software error and it has only recently started happening and only with Eclipse (specifically the C/C++ IDE as that is what I use). This was the case for Neon and now Oxygen. I just recently updated.

Hi George,

I am sorry to hear you are having problems with your CPU and fan. It sounds like Eclipse is doing a lot of work. Do you believe that this work to be in error? If so, can you provide stack traces (use jps/jstack) of what Eclipse is doing and your setup (how big is your C/C++ Project for example)?

Eclipse itself has no direct control over the fans of the CPU. It indirectly will cause the fans to start as Eclipse is multi-threaded and can easily use all available cores/threads on a CPU.

HTH
Jonah

No you see that's the thing. The fans will literally start up when I open Eclipse from scratch. No projects have to be running. I uninstalled and reinstalled eclipse and the same issue persisted. Help?
