Clevo 570TU - modded for silence with resistor -> direct shutdown after 5 minutes

Hello all,

Become dizzy of that fan noise the whole day - yes its also the laptop I work on - I have added a 35 Ohm resistor to the power of the fans.

Now my laptop is very quiet, I really love the silence now, I only hear my harddisk spin (and thats not annoying)

Temps are now:
- Idle 50 C for GPU, stressed 65 C
- Idle 30 C for CPU, stressed 55 C

The problem now is..
That after a minute or 5 the laptop shuts down immediately, no log of, just a soft *pwaw*...

How to fix this, I think the motherboard/BIOS checks if the fan is running to slowly, and then shut off if it is.
I looked in the BIOS, but found notting.. Anyone have an solution?

Thanks in advance all!

 

obviously... when you put in a resister you decrease the voltage and the current, thus less power gets to the fan. The fans are silent because they are not getting the power needed to spin fast enough. the bios is telling your computer to shut-down so you don't fry the motherboard. the obvious fix is to remove the resistor.

 

Maybe try another like 15 Ohm? If that works then i´ll do this too.

 

I'm no electician expert, but what about doing the opposite? I don't mind screaming fans, a little extra RPM might be nice.

 

Thanks you two! No I dont move that resistor ;-) I want a silent laptop.
And yes, I would try a bit less Ohm, 15 Ohm or so.

I was just thinking.. There is a cable that checks the rotational speed of the fans.

If I just cut it by, then it receives no information of slow running fans, so I hope that it does not shutdown the pc.

Is that an idea?



Edit: @emike09, maybe something with a spool?

 

If you wanted a silent laptop, then why didn't you buy a different laptop? Forgive me, but this is the stupidest idea I've heard of in a long time. Now your laptop is going to be hot and somewhat quiet like the m15x. Just use silent mode or buy a P series and undervolt it if you want quiet fans.

 

If you do that i think maybe the NB will not let you use it. You will have alarm warning from boot up, something called selfprotection.

 

One word: LOL
Explanation: when I bought this laptop, I didnt know that it was such a blazing thing..
And no its not going to be hot, 30 C CPU, and 50 C GPU, is not hot.

And if you dont know: the silent mode is just one of the stupid things ever invented, because this only show down the processor, notting with the GPU, and thats the loudest one.

Edit: @kaltmond: I try it, and post my findings here.

 

I agree with the others, you are BEGGING to turn your high end gaming rig into a paperweight. Each time you run that machine without proper cooling(properly running fans) you risk baking the cpu and gpu.

 

Those are your idle temps, DelphiLynx. When your notebook throttles to full load with the fans held back, the temps will be higher as opposed to full load with the fans not held back. I don't know which CPU you have in your M570TU, but I can assure you that it's safer to keep the resistor off the board.

You're fumbling the ball so hard right now it's not even funny. The CPU fan is the louder of the two fans. Silent mode, on the latest BIOS, kills the CPU fan and keeps the GPU fan at minimum. Yes, silent mode doesn't restrict the GPU like it does the CPU, but this mode is meant to be used in light work and idle conditions. Only a moron would game or run more intensive applications on silent mode.

With all that said, stop installing parts from your Boe-Bot onto your notebook. Keep freshman mechanical engineering out of your performance notebook. Come back here after you fubar your notebook so I can laugh at you.

 

Wow soviet, very well written. If he fries it the vodka is on me! You will have to point me at a good brand tho, my drinking was mainly schnapps.

 

Sorry, I'm a touch buzzed myself again. I'm almost through a bottle of Heine and two hours of pubbing on Counter Strike.

Kirkland brand Vodka, akaltenbach. Lately I've been trying to pinch pennys so I won't be tasting any of the finer spirits anytime soon. Kirkland brand is still good enough. Best buzz for the buck.

 

I know the penny pinching myself quite well. I figure we at least owe the passing of a fine chassis like this a farewell toast.

 

Haha you you are suddenly on drinking booze!!

I read very carfully your posts, and I know now that you are right.

But.. I have stress tested, both my GPU and CPU with benchmarking programs, those temps looks very colt to me, 65 GPU and 55 CPU, notting to worry about yet? I mean, how can I bake my GPU and CPU with those temps.

I have a P8400 2.26GHz.
Used: CPU burn-in and rthdribl 1.2 for graphic stresstest.

Edit: oh and really, I have BIOS 1.00.12, but silent mode is just not very silent on my lappy. Not as silent as you described in your post.

 

CPU burn-in is nothing compared to Prime95/Orthos. The same thing with the GPU. rthdribl 1.2 is nothing compared to Furmark.

Download Orthos and Furmark and give it another go. 15 to 20 minutes is the norm. You will get the "true" maximum temps for your components.

I just read your edit. 1.00.12 has different fan settings compared to the the latest 1.00.17, so I understand your point. Silent mode on 1.00.12 will keep both the fans at minimum speed.

 

Soviet Sunrise, I did not know that, I should test it with Orthos and Furmark. But is there a new BIOS!?! I should first check it out where to get it. Is this also for the m570TU?

Oh, and I think you mean 1.00.17 in your last sentence.

 

1.00.17 has been out for some time already. It's a small audio update that branched off the 1.00.16 build.

No, I did not mean 1.00.17 in my last sentence. 1.00.12 keeps both fans at minimum. 1.00.17 keeps only the GPU fan at minimum and turns off the CPU fan.

Here is the page for all of the BIOS and keyboard firmware releases for the M570TU. Make sure you install the keyboard firmware 1.00.11 from the 1.00.16 bundle first before installing 1.00.17. Again, make sure you install them properly. http://www.clevo.com.tw/en/e-services/esupport/MarketDLOut.asp?model=M57xTU&go=GO&type=BIOS

 

Thanks, oke, I am trying to find that 1.00.17, and saw on this forum that 20a already is out, but looking where to download.

Edit: I try that bios, and I stress test with those programs, and post my findings here.

Edit2: Thanks for the link!

 

Nice way to ruin a laptop lol

 

The reason your laptop shuts down, is because the motherboard gets a message from the fan sensors that they are not spinning at correct speed compared to the power they are given.

Here is an example:
The motherboard gives enough power to a fan to spin at 5000rpm.
But since you have a resistor there, it can only spin at maybe 2500rpm.
The fan sensor sends back a signal, saying that it's spinning at 2500rpm.
The motherboard wants it to spin at 5000, but it only does 2500rpm.
Solution: Motherboard shuts down computer to avoid damage to hardware.

I don't think there is any way to bypass this check. If you cut the yellow wire or whatever wire it is that sends fan sensor readings, I don't think your computer would even start.

Why not try this mod instead: http://forum.notebookreview.com/showthread.php?t=389417

 

Objectivity's mod is actually not half bad. The way he did it is a little primative for my taste, but he did manage to replace the loud CPU fan with a quieter, albeit hacked, GPU fan without compromising cooling power to the CPU.
