Y510 Fan bearing lubrication

Problem is that at higher RPMs, after CPU temps reach around 55-60 degrees C fan starts to generate high pitched noise. Is there any possible way to let a drop of mineral oil into the heatsink fan of my y510p? I found out that where normally a small removable cap would be, there is a seal. There are also ball bearings visible under some yellow plastic. My warranty is over, but wouldn't like to buy a new fan, as it seems for me this is a popular laptop fan problem.

I dont't know whats under the seal. If i could just make a hole with a drill in it very gently and then cover it up with something that would be enough, but i dontknow if it would work.

Re: Y510 Fan bearing lubrication

Welcome to the Forums Piotre! 

 

Fan is very loud when the CPU load increases. Possible causes could be dried lubrication in the fan, worn bearings, or just a dust build up. Hence try cleaning the fan once.

 

CPU is running very hot. Applications like tp fan control can tell you the temperature of the CPU and GPU temps above 80C under load are high, and above 90C suggest that the fan or heatsink could be clogged.

 

Ambient temperature should be taken into consideration. PC will shut down during increased loads on the CPU or GPU. This happens when the CPU or GPU overheats - typically above 95C. It’s a protective measure taken as to not fry your CPU.

 

  1. Did you do a BIOS/driver update recently? Click here to update the latest BIOS driver.

2. If you open up your task manager, do you see any processes that are consuming high percentages of CPU?

 

3.Also run virus scan with the latest virus definitions and check for no viruses or malware. 

 

4.You should also install a temp monitoring program and post what your temps are.

 

Let us know how you get on.

Regards,

Shashi

Re: Y510 Fan bearing lubrication

I've recently updated BIOS to 3.08v. I also cleaned everything from dust and changed the termal paste. At idle my CPU is around 50 degrees C, during load around85C, never past 90 in AIDA64 (ambient temp 23C). Virus scans from latest GDATA show nothing. No other consuming programs running.

Re: Y510 Fan bearing lubrication

We are sorry to hear that your issue has not yet been fixed.

 

Infact, there is nothing called mineral oil for heatsink. I would suggest you to visit the nearest authorised Lenovo authorised support for hardware assistance. Since doing anything would harm the system board or any sensitive parts.

 

Let us know how you get on.

Re: Y510 Fan bearing lubrication

Oh sorry I didn't mean mineral oil for a heatsink. I ment something like vaseline oil for sewing machines, which could lubricate the bearing in a fan. If I would attempt anything, I would first detach heatsink and the fan from everything.

Re: Y510 Fan bearing lubrication

Welcome to the Lenovo Community Piotreksss !

 

I'm not an owner of your model, but generally heat sink fans will have a paper label in the center hub area of the fan.  If you carefully pull this label back it will expose the shaft and bearing where you can then apply a drop of oil.  Sewing machine oil would be a good choice as that lubricant doesn't get gummy over time.  Once oiled, replace the label so that it provides future protection against dirt.  If the label is torn and can not be replaced then removed the old label and use a thin piece of tape to cover the opening.

Re: Y510 Fan bearing lubrication

Hey! Finally what I was looking for. I have one more question.

Here is a picture of my fan with removed label: http://imgur.com/ZOSv1Pl

As you can see in the picture i tried to puncture the seal hoping it wouldn't be to deep. There is also that yellow see through plastic which i mensioned before and underneath it balls of the bearing. I can reach each of them with a syringe. Question: should I apply the oil directly on balls?

Re: Y510 Fan bearing lubrication

As long as you can access the ball bearings directly I would apply to drop of oil to them.  Then rotate the fan 180 degrees and apply a second drop of oil.  The ball bearings will then roll and distribute the oil inside.

 

Also from your picture I see the fan blades have accumulated dust on them.  I would use this opportunity to use some compressed air and blow them off.  The accumulated dust can add weight to the blades and increase fan noise.  I would lightly hold the fan blades to keep the fan from spinning and blow off the dust.  Then rotate the fan and hold it again to clean another section of blades.  You want to keep the blades from spinning as prolonged blasts of air may damage the fan.  If you lightly hold the fan in place then no worry about over spin damage.
