Precision M4400: "Again" Fan noise problem!

I have one more question. Isn't that 1920x1200 resolution too much for such a small 15.4 display? I used to have 1920x1080 on 16" (XPS16 which I returned because of overheating) and everything was too small for me. But I read that the 1440x900 would be probably grainy which is not good too. I'm really not sure about the display. Please help

 

Please tell me, when are your systems starting the fan @ 3000 RPM. Which temperature do you reach until he begins working.

It would be good to know, when the fan starts working and when not!

Maybe this helps you. I made a test and turned the M4400 completely off for about an hour. After this I turned it on and made the first screenshot where the fan is off. After this I waited until the fan starts running. Now I made the second screenshot. Ones the fan is running, he will never stop running again. After pressing "FN+Z" to reset the sensors the fan turns off again. Then I made the third screenshot. After a view seconds the fan starts over again, also at thos low temperatures, seen in the 4th screenshot.
Do you have the same behaviour?

FAN OFF:


FAN ON:


FAN OFF (after Pressing FN+Z)


FAN ON AGAIN

 

At firts, I do not have this laptop yet but I want to buy it.
Second, no I do not have similar behaviour on my laptop.

Values on both screenshots seems to be very close without any significan change. That is really wierd. Did you try to call Dell support?

 

I've spoken with the DELL support 3 minutes ago. And yes, Dell knows that behaviour. As far as I got the supporter right, the system is designed to be a HighEnd workstation. 3000 rpm fan speed at this temperatures seems to be wanted by the bios programmers. Also it has to be quite normal that the fan is running all the time without turning off again.

The supporter tried it just in time by using a Precision M4400 by himself and yes, also at Bios Version A12 the fan has to start at this temperatures.

His opinion was "When using a HighEnd machine, 3000 rpm in Idle is ok"

But he will test it a little deeper and give my his results.

Maybe a newer Bios Version will fix that, but he could not promise me that!!!

 

Which Laptop do you work on, and which behaviour do you have in fact?

Thank you

 

Now I have Dell Studio XPS 16 but I returning it back to Dell because of hard overheating under full load. My configuration is C2D T9400, 4GB DDR3, RGBLED 1080p, 500GB 7200RPM, ATI HD3670 512MB... In idle I have almost the same temperatures as you have. Fun is also running all the time, but in idle and under low load it is running on lower rate so it is fairly quiet.

Maybe you should ask guys at official M4400 thread. If they do not have the same experience as you have then Dell support is wrong and you should call them againg and ask for explanation.

 

Its so funny... you blame dell for an hardware issue with the CPU while not realizing your gpu heats up... lolz!

The Fan is responible for cooling both CPU and GPU. The CPU is cold as ice, but the GPU heats up. What you think the fan does?

quote from the other thread:

 

thats probably the reason. i forget the TDP figures of the fx770m vs the fx1700, but i remember it was almost double.

the fx1700 does run considerably hotter, thats probably why the fan needs to be on more to keep it at 50 ish degrees. my unit with the fx770 is quiet.

 

Same here.
I just googled the TDP date from the FX770m; its 35W

The next edit will bring the FX1700 TDP if i can find it - Here the Edit: FX1700 TDP: 50W

Official nvidia data:
FX770
FX1700

 

yea 50w is pretty darn high. the QX9300 (core2quad extreme) is only 45w TDP, and it has much better thermal management than nvidia chips
