I'm running OSX 10.7.5 on my Mac computer (desktop, not laptop).

I have just been watching some Starcraft 2 stream from Dreamhack (in flash) when I noticed my computer was getting pretty hot. I installed some temp. monitor which showed the GPU was reaching nearly 70 degree celcius. This seems like a lot.

I was viewing flash using chrome. I normally use linux and I know there are different versions of flash there, some better than other. Are there any wellknown problems with chrome and the stock flash plugin? Should I be using Safari? Should I install some other flash plugin? Or should I just totally avoid using flash on my Apple devices?

Thanks.

I would say that it is normal for all flash to do this on OS X. –  demure Jun 15 '13 at 13:23
    
Can you check what is your CPU/GPU load while watching the flash. It is not normal to heat up that much. –  Buscar 웃 Jun 15 '13 at 20:47

Flash has many problems, including making your computer run hot. I have an older dual quad core i7 iMac, and Flash does that to my computer too. It's also a large security hole.

I'd recommend removing flash completely, and when you need to run it, do so using Google Chrome. Chrome has a sandboxed, often updated version of Flash. It won't solve the issue with it taxing your system, but it is a bit more secure.

To answer your questions at the end: 1 - Chrome works fine - Flash is the problem.
2 - For Flash, I'd say use Chrome only, and leave Safari out of this. 3 - Chrome provided Flash is probably your best bet 4 - I avoid Flash as much as possible, but I do love me some Google Street View. Gotta use Flash for it.

Good luck.
