Max operating temperature for CCR1009-8G-1S-1S+PC

Dear all,
I am looking for the mikrotik product that support the operating temperature in max 70C, because we will install it in the box without air-conditioner or fan.

I found CCR1009-8G-1S-1S+PC but not clear about operating temperature supporting.
Could every advise and provide me the reference since i need to show customer in my proposal.

Thanks for advance.
