Re: T420s Fan noise Issue

I finally gave in and went 3rd party with TPFan Control.  Disgusted, but my T420s is much more quiet.

I used your settings Kleinbiker - thank you.

 

Lenovo technicians & keepers of this Community - thanks for nothing but frustration and dismay over the last 18 months and 1100+ posts.  No more Thinkpads for me & my company.


I also finally gave up and started using the TPFan Control 3 days ago. However, I am getting more frustrated now because, though I am so happy that my machine is dead silent using the 'Smart' option and the fan does not kick in for a very long time but the temperature i getting high making the machine too warm to use especially the top left part where the CPU is. My minimum temp is 56 degree and the fan kicks in when it reached around 63 degree. Someone suggested to me to use the manual = 1 which makes the machine really cool but it actuallty defies the purpose of using the software because the fan is ALWAYS ON and never stops. So, I am back to the 'Smart' option but first, I am uncomfortable with the high temp that I can feel and I am afraid that this my be damaging the machine gradually without me knowing.

 

All this is happening becuase Lenovo does not make it right and does not respond to a thread of more than 115 pages that started a long time ago. I am not sure if they have a problem acknowledging that there is a problem and fix it or probably they do not care since the sales is going well and companies are buying in batches. Overall, this is my first and last ThinkPad because I learned the lesson well. I need a company that can listen well to their customers and address their problems accordingly.

 

My Machine is T530 with dual-core i7 and Intel HD 4000 only with SSD only. I chose this machine with dual-core and only Intel HD 4000 particulalry to avoid the fan noise but it seems like it does not matter and I am a looser in all circumstances. Hopefully, the time will come soon when lenovo moves and issues a BIOS upgrade that fixes the fan issue. In the beginning, they were asking for people to report the problem to see if it is a general problem and after 116 pages in this thread, it seems like it is not enough for them.

 

If anyone can advise me regarding the TPFan Control settings and if I should continue to use it without harm to the machine, I will really appreciate it. We, as customers. left off with no options except getting each others' advice becuase the company that sold us the machine is SHORT.

I am very satisfied with TPFANcontrol so far. It keeps the system absolutely silent during normal tasks (surfing, writing etc) while still revving up the fan when needed to keep it cool (VMware, watching HD content..)

If you like I could post my configuration.

 

But nevertheless I feel betrayed because letting the system run at a minimal cpu temperature of 45°C (who knows if there aren't any higher temperatures just not sensored?) will certainly decrease lifespan. But hey, Lenovo provoked that and I still got a decent amount of warranty time left so what.....


Would you please post your configuration for the TPFan Control?

Re: T420s Fan noise Issue

I almost didn't buy a T420s because of the discussion in this forum.  I took a chance though, and I am glad I did.  My computer (i5, solid-state drive) makes no discernable noise regardless what I am running.  I primarily use Adobe Lightroom, which is graphics intensive.

 

If I put my ear to the exhaust vent, I can hear the fan running and feel the hot air, but only if I put my ear to the vent.

 

Perhaps Lenovo has solved this problem.  Perhaps I was lucky.  Perhaps the problem will develop later.  In any case, this computer is working great, and has been for the nine months I've had it.

Just got a T420s from Lenovo Outlet and ran into this issue. Issue persists with the latest Thinkpad Power Mgmt driver using maximum battery life profile and latest BIOS.

So I installed TPFanControl. Modified the Smart Mode 1 profile to :
Level=45 0 // Level=140 0
Level=50 1 // Level=150 1
Level=55 3 // Level=165 3
Level=70 7 // Level=175 7
Level=90 64 // Level=195 64

And the problem is gone. Am using the laptop for browsing/email primarily and temperature ranges between 45-50 so fan is almost never on.

Thank you kleinbiker for posting your TPFanControl settings.

My T420s is silent by using your Smart Mode 1 profile. :smileyvery-happy:

Re: T420s Fan noise Issue

My T420s will be my first and last Lenovo product. The fan speed issue is inexcusable, even windows reports an error with the EC controller every time the fan start to get stuck at 4000RPM. TPFanControl worked at first, and made it tolerable. Now, however, there is an incompatibility between Lenovo Power Manager and TPFanControl. Using both together causes spontaneous hibernations for me. The issue is listed as the first FAQ on the TPFanControl website. So now there is no way to make this product usable.

I am in charge of deploying over a hundred laptops to employees at my place of work, and Lenovo has just kissed all future contracts with them goodbye.

Dear Mod,

 

Thank you for deleting my previous posts.  It looks like you guys are trying to hide something.  As I said before, T420s owners are still waiting for a 'solution'.

 

Your pal,

Peednus

Re: T420s Fan noise Issue

I updated BIOS to the latest 1.35 and I'm running Windows 8 Pro 64.  At 47 degrees Celcius, the fan still runs at 3580 rpm.  Anyone else have anything similar with Windows 8?

Re: T420s Fan noise Issue

2012-11-27, 9:49 AM

Hi All,

 

I've been a lurker on this thread for quite some time as I had the fan noise issue.  Figured I finally post as I was just able to fix my noise problem and hopefully my solution can help others. 

 

To start, a bit of background...  I've had my T420s (with the discrete Nvidia graphics card) for some months and it had always had the fan noise issue, it gets really loud when I use a 1920 x 1200 external display.  I've tried almost everything, upgrading to latest bios, getting latest video card drivers, the power management thingy, etc.  I have to say they all seemed to help it a little bit and I think the bios upgrade helped the most.  Unfortunately, anytime I turn on Visual Studio and SQL Server 2012, the fan kicks in and the fan noise comes right back on.  Basically, anytime the cpu gets a bit stressed. 

 

I was about to give up (by getting another laptop) but decided to give it one last try.  The last try was to replace the fan itself, a hardware solution.  And it worked!  I'm posting this on my T420s with a bunch of applications running, the fan is on but no more annoying noise, just a quiet whooshing.  So I'll post my steps here as much as I can still remember it.  Note:  You should be comfortable with replacing computer components before attempting this, as the whole thing isn't that trivial. 

 

1. Order a new fan assembly. 

I got mine from ebay and got it shipped all the way from China.  The new fan I got was an AVC Model BATA0507R5U and cost around $40 (includes shipping).  The old fan I replaced was also an AVC same model with revision: A01.  I don't remember exactly what but the new fan had a later revision.

 

2. Order Artic Silver thermal paste. 

I got mine from Amazon for $20 for a big tube and used like 1/20 of it so I suggest get a smaller amount :)

 

3. Disassemble your T420s.

a. To reach your fan, you have to basically completely take apart your laptop.  It sucks.  To make matters worse, there's no Lenovo support diagrams on how to replace the fan for the T420s.  There's one for the T420, which is helpful to give you an idea but not quite it.  Also, before you begin, lay out some space for you to place all your screws and be sure to snap some pictures of how everything looked before you take things apart. 

b. Remove your battery.  (diagram available on Lenovo support)

c. Remove your hard drive.  (diagram available on Lenovo support)

b. Remove your memory cover.  (diagram available on Lenovo support)

c. Remove your keyboard. (diagram available on Lenovo support)

d. Remove your wireless card(s) and disconnect the wires. (diagram available on Lenovo support)

There's basically some antenna wires that connect from the lcd to your wireless card(s) that you have to disconnect in order to remove the palm rest and the lcd.

e. Remove your palm rest. (diagram available on Lenovo support)

This has a lot of screws.

f. Remove your lcd. (diagram available on Lenovo support)

g. Remove the motherboard (NO diagram available from support so take pictures first and remember where all the screws are)

I think there's like 3 or more screws holding it in place.  Some screws are difficult to see or slightly hidden so just slowly try and wiggle out the motherboard and see where the tension is at to locate all the screws.

 

4. Remove the old fan.  (no diagrams from suppot)

Once you have the motherboard out, it's easy street.  The fan is just attached to the motherboard by the 4 heatsink screws. 

 

5. Scrape off the crappy thermal paste that comes with the new fan and apply the Artic Silver thermal paste to the two spots.

For all I know, the problem might actually be having proper and enough thermal compound applied between the fan and the gpu, instead of the fan itself.   But might as well be safe and just replace the fan and apply proper thermal paste to be sure the problem will go away.

 

6. Install fan.

 

7. Re-assemble computer.

 

And so that's what fixed my noise issue.  Cheers.  Hope this info is at least slightly helpful to the DIYers out there.
