I mounted a 4690K with its stock heatsink on a Z87, bios settings by default. The case is open being a test. MX-5 thermal paste well applied and heat sink mounted correctly. T-amb 20 °.
The temperatures in IDLE are between 34-40 °.
In FULL (with prime95, IBT, Linx) they rise to 100 °.

Do you think it is normal for this CPU or is there something wrong?
What could I try to do (besides changing the stock heatsink)?
