15 blade fan or 19 blade fan?
Now there is alot of info on this topic some claim that a 19 blade fan will help in cooling a PS3 and some say it's BS. Now a 19 blade fan was manufactured in Japan and released in the Nov, 2006 - Jan 2007 batch of PS3's after that production was moved to China and that batch of PS3's have a 15 blade fan. The Slim comes with a 17 blade fan, the reason I mention all this is because 2 issues seems to come up often is fan noise and heat. The theory is that if you replace the 15 blade fan with the 19 it will help quite it down,there are no facts to support this theory and that the 19 blade fan will move more air to aid in the cooling of the PS3. There are a number of reasons for these 2 issues.
1)Location and Position of PS3
2)Room Temp.
3)The PS3 itself.
4)Maintenance
Number 3 is a tough one since no PS3 is alike,I have heard that some are loud and some are quite regardless of model #,HDD size,Fat or Slim. Some PS3's have one batch of CPUs GPUs and so forth,while another group of PS3's will have a different batch of the components, which means no PS3 will have identical specs of these components. This is why these 2 issues happen to some and not to others.
