U510 overheating even after cleaning and Thermal paste change

I'lll start out by saying I'm not generally tech savvy... I have a 4 year old U510 that has served my purposes fine for some time but for the last year has been overheating too easily.   When it does, the fan starts making a lot of noise and I can sometimes get it to stop for a while by blowing some compressed air into the exhaust grill.

I had already tried cleaning the fan and grill but with not much effect so I finally looked up tutorials and took the whole thing apart and replaced the Thermal Paste as well as cleaned every surface I could get to.  

At first this seemed to be the solution but now after only 3 days it's overheating again though not as badly as it used to.   I can actually get it to run without overheating by setting it on two ice packs but of course that's not a solution...

 

Is there anything else to try?  Settings of some kind? Replacing the fan?   I'm in the market for a new laptop but I'd still like to keep this one as a backup.  

Also, I don't use it for anything that seems heavy duty to me.   Firefox with several tabs open at once is about as much a demand as I put on it.    I'm not gaming, photo processing, etc.

 

It's running win 8.1

 

Thanks!

Re: U510 overheating even after cleaning and Thermal paste change

Hi LocalHero , 

 

Welcome to the Community Forums.

 

Since cleaning the fan and vents already improved the heat issue a bit and if the fan noise would still be persistent then you want to replace the fan. Since it is still mechanical in nature , stress and strain on its assembly may happen in due time. Cooling pad at the bottom can also help.

 

You can check on the fan part number from the parts lookup site and use it to search for local resellers or directly from lenovo encompass for pricing and availability.

 

Checking with full diagnostics can also help along with temperature checkers .

Decreasing active processes using clean boot would also help improving performace enabling only those you only need at start up .

 

Hope this help answer your query.

Update us how things go.

 

Regards

Re: U510 overheating even after cleaning and Thermal paste change

Thanks so much for your reply.   Following your links I installed Lenovo Solution Center but it seems to find nothing wrong.  

 

I followed the instructions for a Clean Boot and I can't see any difference from that.   I expected that I would have to reconfigure startup programs after doing the clean boot exercise but I see the programs I do want running are still starting at bootup.  (Ditto clipboard manager, Faststone capture, etc)   Maybe I didn't do something correctly....

 

Lenovo no longer has the fan as a replacement part but I can find it easily online so I guess that's my next step.    I guess that would only help if the old fan is no longer working efficiently?   Maybe it would work just as well but at least be quiet about it.

Looking online I see that this is not an uncommon problem with this laptop but I haven't found any solutions...  :-/

Hi LocalHero , 

 

If LSC did not detect any issues with the other parts then it would most likely leave us with the fan causing this heating issue and not much on overloading processes running on start up and usage. 

 

From the hardware manual , item 18 VITU5 page 68 Fan part number 90201877 that you can search among other resellers

You can also use your serial number from part look up page to show more for the fans if there are other subsitute recommended. 

 

Regards

Yes thanks, I did all of that and in the end ordered a fan via Ebay.   Comes from Hong Kong though so it will be a while before I can test it out.
