Iv been playing my switch for 4 hours today and noticed my fan on the system was kicked on full blast with the back so hot it was really uncomfortable to touch it I did have it in a nice case the switch come with and it does not block vent's of the system in anyway but I took it out of the case after that and turned it off tell it cooled down, Now my 1st switch that I have SX os installed does not and never had done this even with that same case on it, just this ebay switch I got, Will new thermal paste fix this or not? Just asking on what others think Because I would like to keep the thing and not return it.
