Changing to 13R2657 long fan

[r2d2]

Hi,

Is it an advantage to replace my original fan with this long fan (13R2657)? I recently got a T42 with GPU problem. I have sent it for reball and is now working fine. However, I have a friend who told me to 'upgrade' to a long fan. My question is, would it help to prevent future issues of the GPU problem? Is it really better having a long fan? If so, how or why? Also would it fit in the 14" T42?

Any advise on this is greatly appreciated. Thank you.
