I pay 5x as much. Where do you get 1kwh for 10c?
Comment on Reducing power consumption of a desktop PC

The simple answer is most desktop PCs will not come even close to that at idle. Even just having a few case fans may draw more than that, without involving the CPU at all.
Laptop devices can do that in some cases with their extra power management features.
That being said, do the math to see if it matters. The difference between 10w and 40w is 0.7kwh per day, at least where I live that’s about 7 cents or about $25 per year.
In my case it would be more expensive to purchase a dedicated low power device than it will save me in 4-5 years compared to just using something I already have laying around.

I just added a case fan to my SFF. I went with a compressor style given the space constraints and restrictions (they tend to draw more current because of the load).
It increased draw by <1 watt - it barely registers on the meter.
I don’t think fans really make much difference. My 120mm compressor is 4w on the label (which is peak load, like startup). It probably drops back to 1/2 W after startup. And that’s a huge fan in a compressor style, equivalent to a 200mm+ in a conventional fan.
