Hi all. I'm new to Truenas but I've replaced my old Netgear RNS104 with a server cobbled together using some old PC hardware. I'm just using it as a media server to play mainly 4k content on my devices, ie my Sheild TV and Fire TV Cube.

Specs
i7 4790k
16 GB ddr3 3200
Biostar BT85 mobo

4 x HGST 4TB
1 x TOSH N400 4TB
1 x WD 8TB desktop HDD
1 x 125 GB SSD for OS

Its all up and running great and I've transferred all my media over. The problem I have is power usage. My cpu just runs at 4ghz all the time so my NAS is using 90 watts at idle. Obviously with the cost of energy at the moment I'd like my cpu to down clock like it did in windows when its idling. Any ideas as to how I might go about this? I'm not bothered about Plex and media encoding as all my devices and TV's play 4K Dolby Vision perfectly. Any help and advice would be greatly appreciated.

Thanks in advance

Nick
