I just built my first PC and after monitoring the temps., I realized they are way higher than it should be. It runs about 44-47 C in idle and up to 60 C for normal use. I'm running an AMD A6-5400k with gigabyte GA‑F2A68HM‑H FM2+ mobo. I'm using the stock heatsink/cooler. I thought it wasn't making good contact so I took out the heatsink, put new thermal paste and put it back. It only got worse. Any suggestions on what I can do to lower CPU temperature? Thanks.
