Hi! Above you can see two different cooling system for same X201 thinkpad. There are quite noticeable size differences between different parts of these systems. For example, one has wider cutout for fan while the other fan has slightly bigger amperage.

Unfortunately I have no idea what any of these mean. From your expert opinion, which would you prefer to use?

Might just be revsions, not unusual to have parts change though a production run to make stuff easier or cheaper to make. Assuming they both fit, the .23a fan example looks to have a much larger heat pipe from the plate to the fan. I’d go with that one.

same model, different cpu = slightly different heatsink. use the big one if it fits
