Greetings.

A Noctua NH-D14 keeps its temp to 40 grades, but as soon as I leave my PC for five minutes, the temp increases to 65 grades. Confirmed in the 100% of the cases.

Any idea on why this could be happening ?

It could be the CPU fan slowing during an idle state or some increase in CPU load from back ground operations such as anti-virus or other software that uses idle time to scan or check for updates, etc.

I already tested with the stock fan and still happens.

This is a highly optimized machine, whith no networking services, no cron tabs, no scheduled tasks, or related. 

The issue is present both in Arch Linux and Windows 8. Both 64 Bit.

I wasn't referring to an issue with the heat sink fan. What I meant was the CPU has various thermal states and the CPU fan speed changes as a result of the physical and thermal loads it senses based on how it's programmed in both the BIOS and internally in the CPU. If your CPU fan speed in the BIOS isn't set to 100% for the fan then it's possible for the fan speed to become too slow for the idle load temp and the CPU temp will climb. Then the CPU would sense this and cycle the fan to a higher speed to cool the CPU down.
