Recently built my first rig, using i5 4460 3.2ghz and its intergrated graphics while i wait for my new gpu, but just check temp after browsing web, and its 91 degrees celcius, im scared to turn on my pc now cos it might catch alight, is there any possibility this is wrong or there is a way to fix it, i am using a stock cooler with pre-applied thermal paste, should i replace the paste or cooler?
