My new NP9262 runs cool.

I've been running some temperature tests on the GPU of my new NP9262 (got it yesterday) and I am impressed. For reference I am comparing temps with my Alienware m9750 (7950gtx gfx) which is now waiting for repair. I tested with the game Splinter Cell Chaos Theory which I had previously tested on my m9750 and the temps are running significantly cooler on the Sager(using RivaTuner). The AW gpu ran temps in excess of 90C with this game, but the NP9262 never got above 71C with normal fan (all settings maxed out) and dropped down to 58 C with the fan toggled to high. My AW gpu idled around 60-62C but the Sager idles at around 41 to 43C.

I can only assume that the better temperature profiles are due to a well engineered cooling system and possibly the gfx card (9800GT vs 7950gtx).

NP9262 specs:
LCD: 1920x1200
HDD: 300GB 5400 RPM
CPU: E8500 3.16 GHz
GPU: GeForce 9800GT 512 MB RAM
Memory: 2.0GB 800 MHz single stick

 

I'm not surprised.

the D901C has the beefiest specs and cooling system around... 4 large diameter fans, large heatsink/pipes, and a Fan Toggle.

thats just as good as it gets for a raw powered mobile workstation.

 

yep...Clevo notebooks run extremely cool compared to the competition...even my NP5793 (Clevo M571TU) runs cool...GPU idle @ 37C Full Load @ 53C....CPU idle @ 18~25C CPU Max @42C

 

haha, the d901C has a very small cpu heatsink. The cpu cooler in the d900k is like 3 x as big.
It definitely does not have the best cooling.
The d901c like its younger brother and sister the d900t and d900k, all come stock with SamLam technology fans. In my opinion, they are really bad fans. I upgraded my harddrive and cpu fans to high end precision engineered EBM Papst's and the system runs much cooler than it ever did with the stock fans. Plus it runs even quieter because my fans are made in Germany with sleeve bearings instead of ball bearings. My harddrives never break 94F under full load, my cpu barely ever runs over 50C and my gpu runs at 55C under full load.

The 45nm dual core does help too.

 

the d900t/k does have better cpu cooling but is much more nosier.

 

hummm...not mine...it's chilling at about 62-65...

edit: my temp software was not calibrated correctly. temps are 46-50 on idle

 

Hello,

K-TRON could you indicate a store where thse fan replacements for D901C can be bought?

Thanks

PL

 

they cannot be bought in stores, they need to be custom made fans. They are not cheap either. If you are willing to spend $600+ to upgrade the cpu fan, than you can do it, but otherwise its not. I made a CAD file of my fans, which I sent to EBM Papst, in Germany, where I had a custom fan array made.

K-TRON

 

600$ wow!!!! I guess I will stay with the original fans.

@Loggie: do you notice how loud the fan is?

 

When the fan does not run on high speed mode, I can't here it unless I put my ear close to the exhaust vents in the back. When I toggle the fan to high it is
audible and would be objectionable if running in desktop mode but not really noticeable when playing games with audio running.
I never have found the need to run the fan on high when running all of my non gaming applications since the GPU temp remains in the low 40C range. I don't even run the fan on high when gaming since the max temps I have seen so far with any of my games is 76 C (BioShock maxed out settings). And as I said, you don't really notice the fan noise on high speed when gaming.

 

Which program do you use to measure the CPU temperature?

I use Coretemp which measures each core and they're between 55 and 60 degrees - idle - which I think is way too high.

Everest Ultimate just posts the CPU temperature not that of the cores, in which case mine'd be in the low 40's.

 

http://www.hwinfo.com/

use this program. it will report your true temps. then cross check it against all your others...you'll find most of them have in correct values.

 

It gives my core temperatures as between 47 and 53. Which obviously are 'better' temperatures...

However, how do I know whether HWinfo32 or CoreTemp V0.99.3 is giving me the correct temperatures?

 

the way i know is...i had been using rmclock and it was forever 5 degrees off. no matter what machine i used it on, it was always 5 degrees higher. and installing it on the np9262 was no different. so when i ran hwinfo32 on 5 different machines and found out that all 5 machines had different temps, but they all matched being over at least by 5 degrees. i ran a nother machine to the cut off point of 105c, well it didn't cut off till 110c. which was how i pretty much got my answer. now i run like 4 different temp apps and always have to compensate 5 sometimes 10 degrees celius. why? i have no idea. it should be rather simple...read the temp, give the correct value......guess that's why they all have a temp offset.
but i do know that hwinfo32 is the correct temp.. so that's what i set everything else to now. including hwmonitor 1.10 and 1.11.

 

RMclock uses an average temp of all cores.... just look at the temps of each core, they are rarely exactly the same.

Example:
- if you have 2 cores, one is 45C & the second core is 55C, RMclock will show 50C.

I got used to it.

 

not with mine running a quad core
when you idle your system for 5 minutes, your cores will not show 10c difference..they will settle to just about the same....with in 2 to 3 degrees. rmclock will average off the higher numbered core.(when set to the correct value)
example 1 shows no load


example 2 shows under full load on all four cores



now, if i didnt to the temp offset with rmclock, it would show 5 degrees higher than the highest temp listed in both cases.

 

Is the Tjmax of the Q9450 100 degrees or 110?

 

i think it's suppose to be 98'c. for that test i ran, it was on a dv9740us model where you can see and have access to the cpu core temp values. that was given for example purposes only. and is not a fact based answer for the 9262 in reguards to max temp. (110. max was 105 for that model)

what it usually does is when the tjmax hits about 98c's the cpu will down clock for a brief second or two then go full throttle.

 

My CPU temps (which I haven't reported) idle at core0: 46 C. core1 42 C. I am using a Core2 Duo E8500 3.16 GHz. Guess the quad cores run a little hotter.

 

so do mine...but i was doing something and didn't want to wait for them to drop that low.
edit: not 42 but down do 46 to 48

 

Are you aware that you can increase memory performance by placing two sticks of the same kind?

 

Q9550:
core0 -55c
core1 -55c
core2 -58c
core3 -57c
(normal fan speed, balanced power option)

Dual 9800M GT:
GPU1 -53c
GPU2 -61c
(with SLI enabled)

GPU1 -44c
GPU2 -50c
(with SLI disabled)

Are those temps fine?
Don't know why I get such a huge difference between GPU1 and GPU2

 

those temps are pretty nice.... even desktops with same parts would love to have those temps.

 

Whith which program were the temperatures measured. I got 3 programs that five 3 temperatures for my q9450 and some are higher than those presented. I do not think that anyone got accurate temperatures until now. I can compare to mine, if I know the program.

PL

 

I use everest and core temp... (TJ Max is 100)
I believe the right TJ Max for the Intel Q9000 serie is 100...

 

My temps using everest at idle are arounf 60 degrees. I will check the core temp with you TJ max 100.

 

If you download the latest version of Everest, the TJ Max will automatically be set to 100 with the Intel Q9000 serie.

 

I only needed 2 GB when I ordered the system, but I wanted to leave open the possibility of an upgrade to more memory in the future. Thought it would be cheaper to simply buy another 2 GB stick than have to replace two one GB sticks with two 2 GB sticks or a 4 GB stick( is there is such a thing).

 

because one gpu is doing more of the work load than the other...

 

hmm.. its funny how come my processor's temps are running higher than all of yours...

i'm only on notebookreview now reading the forums and having my messenger running the background. my fans are set to 'auto' and i'm running on power saver mode.

my temps now are:
51C -core0
57C -core1

they hardly go into the 40s range and stay there... is there a problem with my heatsink/fan? =/

 

people use notebook coolers and even other simple solutions like lift the notebook a little higher off the desk for better air flow.

and your temps are not that high really....

 

well, i'm using the NC-2000 notebook cooler (should have stated that earlier, sorry.)...

 

well then...maybe it's time to redo the thermal paste on the cpu, now that prices have dropped on things....

 

hmm perhaps so. i'll look into it after my exams.

 

sounds good...it can't hurt.

 

yeap, true. thanks.

 

I have the NC-820 Cooler and mine runs pretty cool at around 40 C, maybe even up to 50 C but the weird thing is if i close the laptop cover, the temp goes up to 51 C or so, it seems to be much cooler if I dont close the laptop cover. Anyone notice this on the NP9262? Also the left side of the wristpad is much warmer than the right, i assume the CPU is under there? My GPU idles at 49 C

 

When you close the lid, the screen will act as an insulater keep the heat. When is opened some heat dissipates through the keyboard. I read somewehere (my nc2000 manual I think) that by closing the lead when the computer is on, or imediatly after shuting down will decrease the life of the screen because of the heat.

PL

The left part is warmer because the processor is there and since you have 2 video cards abother card is also there. In the right is the memory and another card.

 

thanks now i know

 

oh another question, how come my notebook cooler turns off after a while when i leave the comp on? is the usb settings turning it off?

 

Either because it's designed to do that (check the user manual) or else in the device properties you've enabled the ability to let the computer turn off the USB devices when not in use (it's a standard power-saving thing) and the computer is turning it off after a certain amount of time.

 

On my old laptop I had similar problem but with a mouse. The problem went away after I installed properly the the USB related drivers (usb controler ??).
