I'm just wasting time on the internet for the sake of it at the moment looking at things (I do like doing that
)
I bought an uprated curved blade fan with a higher CFM that the one Marlin sell (which is now sat on a shelf somewhere) its a 13". I'll have look at the specs
I will eventually get a rad custom made for it (maybe sooner if I have problems as the weather warms up)
Not sure about PM's should just work
