Making this post, as a few of us over on Reddit are all experiencing the same thing.

Ever since patch 7.5 we are finding that our CPU temps seem to be spiking a lot higher around all main cities. Other areas are also affected like Gangos, alliance raids, and even hunt trains. I've personally gone from about 50c-58c to after 7.5 now hitting 70-80c, which is causing my fans to constantly kick into full spin. This is specific to patch 7.5, as this never used to happen, and isn't an issue specific to me, as lots of others on Reddit have been having the same exact thing. It isn't game-breaking or anything, but it is frustrating to hear my fans turn into jet engines any time I do an alliance raid, or just want to relax in Gridania.

Most people, including me, all seem to have the same CPU with this issue - AMD 7800x3d

Anyone got any ideas as to what might be happening here to those of us with this issue suddenly?
