Viparspectra R900 in a 2.5*2.5?

[fauxnacho]

I have found a second hand Viparspectra R900 being sold very cheaply. My tent is only 2.5 feet by 2.5 feet, will it get too hot in there? I want to stick around or below 30deg celsius, high 80s farenheit. Have any of you guys used an R900 in a small space and was it fine? Many thanks

I have a decent inline fan for outtake, and passive intake
