Ive got a 6 month old CM 690 sitting under my desk, and Im thinking about doing a little water cooling. I was curious if any of you had tried to fit a double fan radiator up at the top there? It seems to me that it would fit but I dont want to go ordering stuff and not be absolutely sure. I did a search on google and found one guy that tried to do it. His radiator didnt fit but Im sure there are some more slim radiators out there. Any advice?
