My thoughts are why not mount the rad to the top of the case where the 140 is now. Then put the fan at the back of the case as an intake and redirect some airflow down to the vrm hs. This could be done cheaply with some plastic I am sure. It might look a little ghetto but you wanted cheap and you could do that without spending anything I would think. Other option would be to do like I said and instead of building a duct get another little fan to do the job for you.
I guess I'll see how things go with my new fans (should get here wednesday, so sad I need to wait ;_; ) and summer, probably won't need to crank on the AC for a while... 88 today but 57 high tomorrow, next highest temp in the next 5 days is 62. Crazy huh?
