I recently bought the i7 4790 and I'm using the stock Intel cooler that I was previously using on my i5 4590 with the gigabyte h81m motherboard. I noticed the temperatures being stable but sometimes jumping above 70°C. Sometimes even spiking up to 79-88°C. I'm also considering buying an ID-Cooling A410 single fan air cooler but I just wanna see how well undervolting would work, just for testing purposes. I know how to undervolt a GPU but I don't know how to do it for my specific CPU.
