    Not sure if this is widely known or covered, but I thought it's worth sharing:

    My X220 with core i5 did become increasingly warmer, with top temperature of 96° reached very easily and the CPU throtteling down. I've now received a replacement fan, and temperatures are much lower - under full load 78°, idle 50°, more than 20° less than before.

    First I thought the issue was dust, but the old fan was not dusty at all. It looks like Lenovo is using a newer fan generation (probably the same ones as the X230). The old one just has metal at the top, the newer has copper:

    New: 506245886_794.jpg

    So if anyone wants to get a cooler X220, consider replacing your fan with the newer model.

    chances are... all you need was new thermal paste replacement, the ones from factory are terrible.
    also turbo boost at full load will make the cpu reach 96C. I keep my settings on balanced along with arctic silver 5 runs nice and cool even under full load with stock cooler.

    I wouldn't always say stock TIM is bad, HP and Dell I know use Dow Corning thermal paste, which is actually quite good. The problem is factory thermal paste sometimes is applied poorly, usually resulting in poor surface area contact.

    Well, the engineer didn't clean the CPU, so have a layer of old paste mixed with the new :(.

    But even so and with turbo boost the CPU now reaches 82° max (without throtteling). So a massive improvement.

    I suppose this would be a good thread to ask in:
    How difficult would it be to replace the fan in an X220 myself and how much does the part typically cost? Just wondering in case things go south in the future with this laptop.

    yea lol thats what i meant it was badly applied x.x my had way too much paste on the cpu when i took it apart the first time.

    My T420 also got a quad core 45W CPU instead of the old dual core 35W so that's one reason I had to keep the turbo boost off to keep temp in check

    X220 Service Manual

    It shouldnt be very hard to take apart, follow the manual and common sense and you should be good. fans with heat sinks are probably 20-50 bucks on ebay.

    While it is certainly possible to do yourself, it is far beyond replacing a harddrive or keyboard. On this particular machine you have to completely disassemble it. I was so surprised by this that I took a picture...(on a T410 it's a 1 minute job...).

    I was contemplating on doing this, but never mind.

    Same here..too much work! I have also noticed my X220 getting hotter than usual. I might not have a choice.

    On X series machines - starting with X60 from what I recall - the heatsink replacement is a PITA. Having said that. if you take your time and perform it with an open HMM, it's really not that bad.
