I have a high-end matte 15" 2011 Macbook Pro. It was noisy from the very start start under heavy CPU usage. It still works fine but it's gotten slower and noisier (I've tried cleaning the fans; didn't help) that I'll probably have to replace it soon. Is it possible that some components are just "burned out" and getting slower? I'm considering getting an SSD and re-applying the CPU paste if that helps. I'm also considering selling it and getting the new non-retina one. Is there a good/easy way of doing this? Apple's recycling program offers ~$700 for it, which is a fraction of its original price, so it doesn't seem like a good deal.
