Forget that "Running a fan with it's full speed will decrease it's life and kill it.

Many people in this forum strongly agree that keeping a fan spinning at it's full speed will decrease it's life very fastly or kill it after a period of usage,but depending on my knowledge I don't agree.

These notebook fans dont work with high voltages,so they don't pull much electricity,if they would,the wires inside the motor would heat and won't be durable,but we know that they don't work that much electricity.

Also all the notebook fans have brushless motors,which means they really have a long life,due to the fact that firiction is very low,try turning your notebook's fan if you can,then you will see how much easy it turns.


Imagine,there are millions of electric motors,in remote control cars,in normal cars,in freezers,in elavators etc.

Also I have another proof,I have a 5-6 years old desktop,and it's fans really work at high speeds but still they are working like a charm,as the first day they started to spin.

A friend of mine has a hp pavilion notebook,I dont know why the hell maybe because of a Amd cpu or motherboard,his notebook's fan spins at it's full speed and sound like a airplane,but still there isn't any problem,he has been having this issue for 2 years.Also,if you are really concerned about fan,what about other components?Would cpu,gpu last for a long time if your fan doesn't spin fast?

Just,think a little and you would understand what I mean.

Another fact,

All the HDD's have a brushless motor too,including cd readers and writes,a HDD spins at 5400-7200 rpm but have you seen a HDD motor or a cd reader motor died?

 

Yes, in point of fact, I have, although I'll readily admit that it's hard to tell if it was due to overuse or just a manufacturing defect.

 

notebooker-hp,

I catch a glimpse of what you're saying, but have to disagree with your conclusions. By definition 'using' means wearing out.

Some specific cases as you mention seem to defy this simple fact, but using anything to it's maximum will give you the shortest total time it can give.

There is nothing wrong with that if the benefits outweigh the potential cost; but every component has a finite life span - if we use it up in constant and continual use or if we spread that over a longer time period makes no difference to how long it will last (in usage hours) overall.

Do you see what I mean?

And I too have seen HD motors seized, fans and remote control car/airplane motors die and freezers/compressors/elevator and escalator motors quit too. Things wear out, whether we have seen it personally or not - and this doesn't even take defective products into account either (that might actually last longer if used less than 'full').

 

I had to replace the fans for a friend on a MBP 17 Inch because they were making a terrible noise. The MBP is around 3 years old... and because its a MBP, the fans are always on around 2000Rpm unless you are doing something (video editing we will say) and they will kick up the speed very quickly.

But on the other hand, my Dimension desktop has been on for 5+ years straight(but is around 8 years old now), and the fans still work fine. But i do clean it every few months.

On My Latitude, the fan speed varies from off to around 2800rpm, if i really am doing something that is taking up cpu, it will up it to 3700RPM. i have yet to see the computer take it to max. The only way i can get it to 4470RPM is if i click "force fans to high" in the latitude speed fan control program.

So really, all in all it just depends on your own usage.

That was back in the days when I knew less.

 

Depends there are a few type of fans.
DC Brushless ,Ball bearing fan and Maglev.
