lowering ambient temps?

Hey all I have a swiftech COOL system setup right now and my overclock is 2.4 ghz. The only problem I have is that my ambient temps are very high, the cpu temps are always low 40s but the ambient temp is around 50 degrees which I am worried about. Can I lower this ambient temp by getting a bigger radiator like a bix 2?

ambient temps= the air temps within your case. there is no point in cooling it if your cpu is already cool enough. that just means you need better airflow inside your case. a radiator has nothign to do with ti.

okwell I have 2x 90mm fans pulling air into the case at the bottom and 2x 120mm fans at the top of the case sucking air outa the case. I'm not sure what else to do
