I am curious that if I overclock my PC, GPU, CPU and RAM. Will it overheat? My CPU - i5 4670k GPU- GeForce GTX 780 and I have 8gb of ram. I running off of the stock heat sink fan and that is it. I plan to upgrade soon, (Heat sink fan) around next month, I am just curious if till then overclocking would cause any major overheating or is it safe. I will be running all fans at max if necessary. (Assuming I am doing max overclocking)
