AxysAssault, I did blow mine out with a compressor from the back too. There was a ton of dust blowing out. There is absolutely no space between the radiator and IC to put any kind of wand in between. I managed to get the intercooler out without pulling the radiator, but I fear it took more time then it would have to just pull the radiator too.
