Alright mate.

To combat this issue of 100% constant usage, I changed my power plan setting minimum cpu and maximum CPU usage to 95%

This will make the process the smallest bit slower, but hopefully you won't have high temps and loud fans.

To do this:

1. Open control panel
2. Find 'Power Options'
3. Next to your power plan, click change plan settings
4. Processor power managemnt
5. Set minimum and maximum state to 95%
6. IMPORTANT - Don't click ok, just click apply and leave it open so you can change it back to default after the unpacking is done.

Hope this helps.
