Ok lets cut the story short. I have a 2012 mbp with an upgraded 6gb ram and just few days back i popped in a 120gb samsung 840 evo. But ever since the temperature,as measured by iStat menu,shows considerably higher temperature during normal usage or when running parallels desktop. Its get to about 90 degrees Celsius atimes. Is that okay. I hope it wont fry my computer this is my first mac. Lol. Help out guys!
