Thinkpad T530 coil whine and fan noise

2017-05-20, 7:51 AM

I am considering buying a used T530 with Intel CORE i7-3520M 2,9 GHz and intel HD 4000 graphics


I own a T510 and the coil whine is bad. is this a problem on the T530 with i7?

I understand that there's been problems wiith fan noise, but  a bios update fix that. I am using Thinkpad fancontrol on my t510 and it works fine


I understand Thinkpad fancontrol works on T530, but what is the lowest fan speed.?


My T510 runs around 2400-2500 rpm at lowest speed and the noise profile is kind of annoying, should be a bigger fan really which runs at around 2000 rpm


I am buying with the 1600 display which in reviews says is good. Anyone can confirm this? 



Solved! See the solution

I have bought a T530 and would like to share my experiences


In windows 7:

The lowest fan speed is now around 1960 rpm (level 1) If you don't have that you will need to update your bios

Level 2=2460 rpm

level 3=2690 rpm

Level 4=2929 rpm

level 5=3492 rpm

Level 6=3685 rpm

Level 7= 3685 rpm   (seems like level 6 and 7 are the same and highest level)

Level 128 =Bios


It works nicely with http://www.tpfancontrol.com/

Both version 0.62 and 0.63 works


Thinkfan for Linux also works . Both Linux mint 17.x and 18.x (ubuntu 14.04 and 16.04)






My config in Linux: thinkfan.inf:


hwmon /sys/devices/virtual/hwmon/hwmon0/temp1_input
hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon1/temp3_input
hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon1/temp1_input
hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon1/temp2_input


# Please take notice that the HIGH_TEMP of a rule must be between the LOW_TEMP & HIGH_TEMP of the rule that follows.

(0, 0, 65)
(1, 50, 70)
(2, 68, 74)
(3, 72, 75)
(4, 74, 78)
(5, 76, 80)
(7, 78, 32767)


# I have no idea what the number 32767 means. some kind of max fan level in Thinkfan I found on the internet about 

# thinkfan,  maybe 128 will also works as this is BIOS controll


Fan start at level 1 at 65 degress Celcius and runs until it's down to 50 degress.

It will increase to level 2 at 68 degrees and level 3 at 72 degrees ( if I have understood this correctly)


Anyway it works very good in linux


Some people wuld like fan to start at lower temps, but in my experience most modern laptops can stand higher working temps than decided by BIOS. I have never bricked a laptop running higher temps than preferred  by BIOS control.(I have a SSD so not worried about HD temps)


If you prefer fan to start at lower temps there's a lot of advice how to config Thinkfan on the internet


There's no Coil Whine in my T530, neither in Windows or in Linux


The 1600x900 Display is quite  good to be a TN panel


One thing: The sound from loudspeaker is not very good


use this in Windows:




It really helps.
