I broke off a blade on the CPU fan - does it matter? (TP T440p)

2017-08-26, 15:44 PM

Hello,

 

while cleaning the laptop with compressed air (with the bottom cover removed), I accidentaly broke off a single blade on the CPU fan.

 

Since the fan consists of two layers (cooling blades are both on the upper and the lower side) and the blades are very small, I think there should not be any long-term damage from an unabalanced fan.

 

What do you guys think? Should I get a new (or used) cooling fan? The laptop is now 3 years old and I plan to keep it for 5 more years (I use it daily for 6-8 hours and it runs for 12-14 hours per day).

 

Thanks.

I wouldn't want to run it like that long term. I would probably be inclined to snap another blade off directly opposite that one to balance it out again, assuming there are plenty more blades to provide airflow. I wouldn't want to risk the bearings personally.

My main worry are the possible vibrations that could damage the CPU/GPU on the long term.

 

But the blades are very small, and there are many of them, plus there's a 1st and 2nd "floor" of blades. Mayve this was done intentionally to make everything as stable as possible.

 

A new cooling unit is quite expensive at 45 EUR + shipping. :-/ But I do want to run this computer for many years to come (i5 processor, 16 GB RAM, 2x SSD).

I see your point, even if the blades are very small the imbalance will be there and may be enough to shorten the life of the bearing in the fan. As for the vibrations damaging other components I don't think it'd be a huge issue. I'd stick to removing a blade in the same spot the other side and forget about it.
