Very nice motherboard...
Yes, you could check that the cooler is fully inserted into the motherboard, but really you need something like a coolermaster hiper 212 air cooler on that chip
If you want to use the stock cooler while waiting for a better one to arrive in the post, just undervolt and underclock your CPU a bit.
For example mine will run 3.9GHz at 1.05Volts Vcore
3.9Ghz is not exactly slow ....
But if you drop your volts and speed a bit, it will generate a lot less heat
The volts makes the biggest difference
