I dont know if you guys know about this or not, but fans will slow down over a long period of time. When that happens it usually cause crash and game freeze and ultimately failed to extract heat fast enough on the heatsink and fry the cpu or gpu. So the better question is how long can both of these hot HD system can last.
I had never open up my HD systems but if its structures is similiar to the cooling system on a PC cpu and GPU, then those fan will start to slow down usually after 1 year. I usually test it out by touching it, if it run like new you feel like a cut to your finger but if it stop with a light touch then its telling you to replace that fan immediately.
