So I've just installed Windows 8.1 on my 2015 MacBook Pro (2.5 i7, AMD graphics) mainly to play games. I'm currently downloading GTA V (around a 60GB file) and have also installed a fan control software that was recommended on these forums. The fans are spinning at around 4000-4500rpm to keep the computer at 50C. Is downloading a large file really that intensive? I'm now worried about playing the actual game! Any tips out there? Also, like OS X, will windows shut down the computer before any damage occurs due to heat?
