Throttle CPU down - Power Consumption

I have build a new server with unraid, my old server a synology diskstation wasnt enough. I build the server from my old computer hardware with the following stats:


M/B: ASRock H77 Pro4/MVP Version - s/n: M80-3B003300095
BIOS: American Megatrends Inc. Version P1.70. Dated: 08/07/2013
CPU: Intel® Xeon® CPU E3-1230 V2 @ 3.30GHz
HVM: Enabled
IOMMU: Enabled
Cache: 1024 KiB, 256 KiB, 8192 KiB
Memory: 16 GiB DDR3 (max. installable capacity 32 GiB)
Network: bond0: fault-tolerance (active-backup), mtu 1500
 eth0: 1000 Mbps, full duplex, mtu 1500
Kernel: Linux 4.19.56-Unraid x86_64
GPU: Nvidia Quadro FX 580

beQuiet 300 Watt


Now, when i check the consumption of the server, it is a little bit high. In idle mode and spin down all disks, the consumption is 97 watt. Measured with Brennstuhl.


The cpu clocking down to 1600mhz on idle and the max frequency is 3700mhz. I tried to find out if i can clock down the cpu even further, but i found nothing. Do you have any idea or another solution to reduce energy consumption? I had read about HP Microserver with 1230v2 CPU and a consumption of 30 Watt. Is the Mainboard so bad or what is the problem?


Thanks a lot.
