My new i7 4790 is overheating at stock speed
Hi I have my new PC - they built it for me in the shop - but I think the stock CPU cooler is mounted fine as the idle temperature is around 29-33C. But when I render videos it becomes extremely hot, around 86C. I found out that the voltage level is very high. It's around 1.155 at 3.8ghz and sometimes goes to 1.228. If I set it to 3.4ghz max, then the voltage is only 1.05 and the tempeature is just around 74C.
What should I do to stop the overheating? How can I undervolt it at max load? It's ridiculous that the i7 needs 1.05v at 3.4ghz but 1.115-1.228v for 3.8ghz at stock speed while even the infamous old 4770k and devil's canyon can run at 4.2-4.4ghz with 1.19v.
Here are pictures:
