2x PCMCIA hgi power in RB230

Can I run a Prism2.5 300mW PCMCIA
AND and SRC 400mW PCMCIA at the same time in Routerboard 230??
They load and show up as interfaces, but I worry about heat…

(and there is another SR2 MiniPCI at the backsite as well)

SRC cards are only 300mW.
I had two in a rb230 running fine from the day they shipped until about a week when I changed them out with rb532s and 1x sr2 1x sr5.
