Replacing Lenovo Thinkpad T420s Heatsink?

[GforgeXr]

I am very tempted to buy a t420s heatsink because of the famous overheating/loud fan problem. But I have this in mind, what if the heatsink I am buying will make no difference and just show the same result as before. So what do you guys think? And do any of you have any experience of where replacing the t420s´s (Not Specifically the t420s) heatsink actually made a difference. The reason why I am very tempted to buy a new heatsink is because my cpu tempature goes up to as high as 89 degrees when browsing the web.

89 C is nothing to worry about in a laptop.

if you replace it with an identical heatsink it wont improve anything

the replacement would need to be in some way superior to the original

more likely to work is replacing the original thermal paste i would think

I´ve already replaced the thermal paste and it changed the tempature dramstically from almost above 100 degrees when surfing the web to about 71 degrees on idle.

like i said then unless the new heatsink or the fan on it is superior to the old one replacing it with the same thing wont help

It is not like this overheating problem is effected to all t420s´s. So it is like a shot in the dark, because the new heatsink may be one of the non-effected or one of the effected.

yes if they used two revisions of the heatsink or different suppliers of them
