Will Fan+radiator+fan+radiator+fan configuration work?

[Frankdel]

I have a micro atx case with limited room and in addition to the Corsair H55 cooling my CPU, I would like to use another H55 to cool my graphics card. No room or possibility to install 2nd radiator against the case. Is it possible to install using a fan+radiator+fan+radiator+fan configuration? Will this degrade cooling ability to a point where it's not worth it? Should I stay with graphic card air cooling temps have reached 90C under load.

Although we don't know what case you're working with at the moment, I'll entertain your question.

An example of what you want to do.

The issue with what you're going to attempt to do is that both radiators are heat dissipation area's for your heatware. When you stack them against each other one heat source will heat the latter so instead of seeing favorable temps, you're actually feeding at least one of your components with preheated air. Why this is a concern? Simple, the way cooler(either air or water) work is that ambient air that is almost always cooler than your heatware is necessary to drop your temps if the ambient air fed to cooler is heated this will in turn raise your coolers temperature.

A case that can accept your coolers will be a first advice. Picking one with a good airflow would be the second and the third would be to list your full system's specs in case the community can provide a more practical solution.
