Lenovo T430 - Replacing the cooling system with a quieter one

Hello.
I have a Lenovo T430 laptop with a quite loud fan. From what I was able to orientate, these models had a problem with that. It is a fan with markings: Toshiba FRU 04W3267 / Lenovo 0B41086. The sound made by this fan can be compared with the buzzing of a mosquito and starts from low revs (2500 rpm).
On foreign forums, they recommend replacing with a fan: Delta Electronics FRU 04W3270 / 0B41087. Apparently it's very quiet. Except that the pictures show that it has 5 cables in the plug, while the original has 6 cables. Well, but it works.
Now the question is: has anyone already tested this solution? Or maybe someone somehow solved the topic of a loud fan in this laptop?
Other parameters of the laptop:
Processor: i5 3320M
Graphics: integrated Intel HD Graphics 4000
Motherboard: Lenovo 2349GCG
Bios: G1ETB1WW (2.71)

Hello, have you dealt with the loud windmill fan?

For now I left it as it is.

I have the same problem with t430.
I relieve annoyance windmill fan software - I use the TP Fan application in which you can use the smart or manual profile instead of the default bios. At least windmill the fan no longer goes crazy arbitrarily as it pleases.

windmill The fan has 7 levels of rotation, usually enough for cooling level 1, reasonably tolerable to the ear, temperature tolerable during normal operation.
You can also use smart mode then windmill the fan starts when the temperature reaches certain levels.

Nevertheless, I have the desire to disassemble the radiator and check if a rotor replacement for one that will help something with less dense blades, clean and grease the axle.
The difference between two models of fans (loud and quiet) lies precisely in the impeller, and the second that the bottom holes of the fan are slightly larger .... but it may still be that it is not the air from the impeller blades that makes noise only the rotation on the axle, which has some firstborn feler.
The difference can be seen in the photo (left - loud, right - quiet)

How's the mute this t430 working?
I am particularly interested in the issue of the effect of lubrication on loudness - in foreign forums, this method of solving the problem has a mass of supporters and opponents (in theory, such components should be maintenance-free).

Recently (I have the version from January 2017) there was a bios update - unfortunately the culture of fan work is not affected ...

fan (greetings to the admin ) was thoroughly cleaned of dust and sediments ... after unscrewing the paw it turned out that I was just running out of machine oil, so I used castrol 5w40 engine oil, and at the same time replacing the paste with cpu.

the effect - at first I had the impression that it works louder than before, after a while I find that there is no difference in noise, so these toshiba fans in t430 (and not only because t420 also) are simply warped. After changing the paste on the cpu temperature at least a little lower so that the fan turns on a bit less often for higher revs (I have the latest bios).

So I was looking for a cheaper replacement option for another fan - but on alledrogo there is no dedicated for t430, there are only stimulants of this fast toshiba together with a heat sink for about PLN 50 and up. I had the idea of putting in as a replacement a 4-pin fan with dimensions that could be stuffed inside, but it is difficult to find one because the stores do not specify the dimensions of the fans, probably the best from asus 1215.

Ultimately, I ordered an inexpensive fan from another Lenovo, which shape fits perfectly, but it is ... a mirror image of that of the t430 (i.e. the motor is at the top and the blades at the bottom) and there is no cover of the blades from below ... However, I have an idea how to deal with it
I'll just say that you will need a 3.2% milk carton, unless someone cares about the line and 0.5% is enough

the shipment is coming from China so far, when it comes and I will successfully implement my patent, I will put photos with the description here.
idea really cheap to make ... about PLN 16 will cost me not counting paste on cpu.
I hope that there will be silence in my t430 soon without using TP Fan Control.

cont. t430 fan stories.

I didn't want to invest $ 25 in a new quieter Delta fan, because it's still difficult to get. I replaced the fan but I did:

- I bought a fan for lenovo x230 / x220 on Aliexpress - it has almost identical shape and holes at a right angle like the t430 fan and the price is only $ 3.11 and free shipping (in Pl the price for alledrogo from about PLN 40)
- and this fan is inverted, i.e. facing the blades down and therefore there is no cover over the blades (because it was originally tightened to the radiator and blades up), but there is no fear that it will slide off the axle because it is held in position by a magnet.

- the package from china came after 18 days so it's not bad

- the fan, however, required small adjustments to mount it (to fit perfectly it was necessary to trim a portion of the metal plate by 2 mm, and above all, to change the order of the cables because the order of the pins did not match - x230 and t430 may have a different order on the pins - only red was correct )

- the original Toshiba fan has 5 pins (and 6 cables), and Delta has 4 pins, but it also works (you only need to insert the pins in the socket from the right side of the socket on the main board; one pin on the left is free).

- I let go of my own hand-crafted cover over the shoulder blades because it was rubbing, and when it was slightly higher than the wall, then there was a problem with stuffing the set inside (the speaker stood out a bit and the cabinet did not fit easily).

- the fan was finally glued to the t430 radiator with double-sided tape in several places, I put it on, connected it and it works ...
- Paste replacement on the Prock by the way necessary.

- for mounting on a main board it is necessary to check before switching on whether the blades rotate freely and do not rub at anything, e.g. blowing on them, etc. .... if they are blocking there will be a fan error at the start of the computer

all you can hear now is the sound of the air, not some hum
but the bios and as before has a snorkel to screw it at a higher speed with the use of the processor and then you can hear this noise more clearly like in any computer .... So I use TPFan further allowing the fan not to go to a level higher than 2, then it is comfortable .

generally it is much better when it comes to comfort, but perfect silence is not obtained because of Bios (1 gear fan is 2500 rph, the 2nd is already 3600 rph which is exaggerated a lot in bios but this type has it anyway) but in compared to a Toshiba fan there is only pure air noise and not annoying sounds (humming) of an old fan at the same speed.

if you have a bit of manual talent and familiarity with spinning the laptop, you can have fun ... or hunt a Delta Elec fan. then even easier and it fits perfectly to the radiator without modifications (just the replacement of the fan).

update :
wiring diagram (on the left the color of the cable in the plug / on the right the color on the motor side):
Red - ed
Black - Blue
Yellow - Black
Blue - Yellow

like someonecan do it, solder the cables directly in the plug - I cut the cables 2 cm from the plug, twisted the wires of the appropriate cables as in the diagram, treated with a soldering iron and insulated with tape ..... and guitar

forsberg21 good job
I'm just surprised that your first gear is immediately 2500 rpm. For me the first is about 1700 revolutions.
I wonder if this can be affected by the operating system? I have Debian 8.

- hmmm and what version of bios does a friend have?

well, unfortunately I have 1- "run" always around 2500 rph. and as I read on the net, it is rather standard in t430, but it should be added that it is win10.

I'll check on Ubuntu someday .... but turnover is more a matter of bios and not an operating system.

Bios: G1ETB1WW (2.71)

I tested the revolutions more thoroughly and it turns out that with a small load, however, the first turns on ~ 2500 revs, and only after a moment of inactivity, when the revs fall, instead of immediately to zero, they stop for a moment for ~ 1700.

Well, somebody smart would have to modify the Bios and fan speed settings, but it's not as easy as I supposed it was googled.


I uploaded pics from the exchange process to the cloud - you can see there exactly the scheme of cable replacement and I have marked by hand how to cut the metal plate so that the fan fits well in place.

in the photos you can also see my cover from cutting it out of the cardboard for assembly, but it did not work - or it rubbed on the blades and as it was possible then there is a problem with screwing the loudspeaker and fitting the cabinet .... I also put it on as it is without any cover from below ...

works, cools, doesn't make noise like toshiba ... for $ 3.11, and now it's even cheaper ...

At the weekend, I was able to check used Delta Electronics 0B41087 cooling system on a known auction site, which is exactly what they recommend on foreign forums. Today, the courier was at my place and I just exchanged.
I will say shortly after 5 minutes of testing - it's very good. When it's spinning, you can only hear the air noise, zero mosquito buzzing like it was in a Toshiba fan. Generally I am soooo happy

For those interested in the cost: cooling Delta Electronics 0B41087 PLN 45 + courier PLN 16.
