power consumption increased at low temperature

[Aki1122]

Hello.

I'm using the DE0-CV(Cyclone-V 5CEBA4F23C7N).

When I use this device in low temperature(about -10 ℃), The entire power consumption increased compared to 0℃. I thought that the power consumption would decrease. What do you think is causing this?

ps 

I know that the operating junction temperature is 0℃ to 85℃.

Hi Aki1122,

As Intel has tested the device to be operated at 0-85, hence, using other than the suggested and tested temperature can lead to a different results and damage the device. Please used the suggested temperature. My apologies, we do not have the data for the device to be operate at -10 and to answer the reason behind its behavior.
