Re: T430 fan

2013-02-12, 17:45 PM

Hi, 

i am very frustrated with the t430 fan sound.

 

I installed TPFC and it is fine now. But will it damage the notebook when the fan is off below 60° Celsius?

Why would lenovo by default let the fan always running? is there a reason for this?

 

By the way, it is hard to get above the 60°C, so I use the notebook without a fan.

Using the TPFan will not damage your system but why buy a premium machine only to run it like an enry level machine?

 

If the fan is disabled, you will not get the "turbo" mode so your system will always run in the low end of the CPU frequency range.

 

If a slower machine is ok with you, then you should just return this one and get a cheaper one. :)

Even if your cpu is 60C which is absolutely no problem at all, it might be bad for other components such as the battery. That's why I want my x230T's fan to keep running at the lowest even if the CPU is just warm.

It's almost impossible to reach lower than 30, but it might happen if I use it in a very cold room. Here's what I'm using for my X230T in tpfancontrol. I don't have to use tpfancontrol since it's already very quiet, but I use it so I can monitor the temperatures and have more control over the fan. X230T mostly stays around 35-45 if I'm not doing CPU intensive stuff, and is very quiet. Too bad the flagship product T430 is so noisy.

 

My tpfan settings:

Level=30 0
Level=35 1
Level=40 2
Level=45 3
Level=50 4
Level=54 5
Level=57 7
Level=60 64
Level=65 128

 

 

Edit: I want to add that it will damage your system if you keep the fan completely off with high CPU usage. The CPU can handle up to 105C or something, but before that, your batteries will get toasty and so will the motherboard.

 

If you are afraid of the heat and also want to kill the noise, I would suggest using tpfan and also restricting your CPU performance to 80% max. This will make it work like a Ultrabook. Lower power usage less heat, of course lower performance (exactly like Ultrabooks). I do this sometimes when the max speed doesn't really matter, and I'm keeping it running overnight.

okay, but what kind of applications do you need to get above 60 or 70 degrees ? For my daily work (some coding, browsing, music, video) I don't reach above 60°

If you meant that you are trying to heat up the machine to test the fan, try prime95.

CPU intensive stuff I do is running simulations, and sometimes playing games like maplestory. During those times, it hovers around up to 55C-60C with the fan kicking in high gear.

if they would reduce fan level 1 to 2000 rpm, everyone would be glad. I don't understand why lenovo does not do so

Yeah, maybe the fan can't go that low because they are cheaping out on the components. My fan is 2968 RPM at speed 1 right now, 37C. I've been working (simple coding) in a linux virtual machine.

I still wonder what the difference was between the 4 wire version fan and the 3 wire version. My first x230t had a 4 wire version, while this 3rd one came with a 3 wire version fan. Not loud or anything, but just wondering if the 4 wire version would allow the fan to go lower speed.

Re: T430 fan

Does anyone know whether Lenovo will return the part they have replaced on your system?

 

I have recently got my fan replaced, but the replaced fan was not returned to me. Is that the normal process?

 

I would have thought they should have returned it to me since it is a part from a system I own.

 

Any idea? Thanks!

That is normal, they don't give users the old parts.

You own a working laptop and they return to you a working laptop.

The fan in the T430 is VERY VERY small, that is why they have to run it at such high rpm to move any airs. To fix this fan noise issue they rally have to redesign and replace the fan.
