NP8662 heat issues

not at all.

undervolting it will keep it cooler and not affect the performance or clocks at all.

all in the NBR Cooling Central
... under flipfire's "Undervolting" Guide

 

I don't know what else you can do. All laptops have this issue to some degree. I'm too sleepy and hungover to get into morals right now so I'll keep it short. Be happy that the heat is frying your hand and not the critical components on your laptop.

 

How about with ACPI, is 71C max normal?

If the Northbridge is the problem with hot palmrest can I remove the thermal pad under the Northbridge heatsink and replace it with thermal paste?

I heard that thermal paste works way better than thermal pad but I see that the heatsink has some black film in between the thermal pad and heatsink itself, so that worries me on applying thermal paste.

 

thermal paste is better... but it will not adhere (stick) and hold down the heatsink properly.

the heatsink will still need to be clamped down.

 

I've researched hundreds of reviews on the subject (M860TU HDD temps) featured on this site as well as from other sources and these are my conclusions:

1) Lower RMP doesn't necessarily mean lower HDD temperature. In fact, even within the same brand (for instance Scorpio Blue versus Scorpio Black) was the measured HDD temperature often lower in the case of the 7200 RMP HDD

2) The evidence and random accounts are contradictory even when it comes to identical HDD types. I read so many opposing reviews that it makes me think that there must be other variables responsible for the reported high HDD temperatures

3) The performance gain of the 7200 RPM drives can be somewhat disappointing when single-tasking but becomes quite obvious when multi-tasking

4) The market (HDD for M860TU) is dominated by the Seagate Momentus product line and the Western Digital Scorpio product line (with Hitachi being the 3rd distant player)

5) I wonder how many of those who installed the Intel(R) Matrix Storage Manager also installed (prior to the afore-mentioned installation) the Intel(R) Chipset Software Installation Utility (INFINST_AUTOL.EXE). Because if they didn't, they may think they have the Matrix installed and running properly, but it may not be the case.

 

i....
did not installed Intel(R) Chipset Software Installation Utility (INFINST_AUTOL.EXE)
now i have installed may i know how it was use? as it just install in.

 

The Intel(R) Chipset Software Installation Utility installs Windows INF files to the target system. The INF files inform the operating system how to properly configure the chipset for specific functionality, such as AGP, USB, Core PCI, and ISAPNP services .... the utility should be installed prior to the installation of the Matrix. Basically, the utility functions as a communiction agent/advisor to the operating system making sure all subsequent downloads/installations from Intel are executed and configured correctly by the operating system. Once you've installed the utility, you don't need to worry activate it in any fashion. But again, it should have been installed before the Matrix.

 

omg i done the opp way.. will reinstall again lol

 

I'm confused here. In my Add/Remove programs (Windows 7 x64) I have listed "Intel Matrix Storage Manager" but that's it. I went and downloaded this program and installed the version of Vista x64 (I use Windows 7 x64). WHY do you say this has to be installed BEFORE the Intel Matrix Storage Manager? Does it really matter? If I already have Intel Matrix Storage Manager installed, should I uninstall now and reinstall it?

Is this going to help reduce heat with HOT hds? My 7200 RPM drive makes my palmrest so hot, I hate using this laptop sometimes. I don't know what model HD it is, can this be found without pulling apart the unit?

 

another set of install cannot be see one it will direct install into laptop

i do some testing by getting another fan (it no brand fan) and i found out the following temp
Fan blow in air into laptop can lower temp quite fast

Fan 1 (Fan blow in air into laptop) - Cap down after play 10min battlefield game


Fan 2 (Fan suck out air from laptop)Cap down after play 10min battlefield game


Fan 1 (Fan blow in air into laptop) - after leaving laptop for 30min with song playing.


Fan 2 (Fan suck out air from laptop) - after leaving laptop for 30min with song playing.

 

I been reading about the heat issues with hard drive for a while, and I think the problem might be that the hard drive near the GPU and chipset causing heat to be trapped inside causing idle temps of hard drive to spike.
I had something similar when I had the MSI GX610 where the hard drive was near the CPU.

Now I have MSI GT627 and the hard drive is by its self near ODD and idles around 37C and 51C load while playing a games.

 

sory off topic question ....kevindd992002 any idea where you can buy spare batt and charger for a sager np8662 in the philippines?

 

Read here >>> http://www.intel.com/support/chipsets/inf/sb/CS-009270.htm

 

I've also had really high temps. Not so much the HDD, but the GPU... I ran the Furmark stress test, and got 99C. This can't be healthy for the GPU right?
Btw, what is the danger/max temp for ACPI. Can't seem to find any info on it.

 

The ACPI is a power management controller used by the OS to control the amount of power given to each device and component on the machine. On our Clevo's it is located on the motherboard very close to the CPU.

In HWMonitor, you can see that the ACPI temperature is higher than the CPU core temperature. The ACPI temperature acts as a margin of error for the CPU core temperature so that the BIOS can properly control the fan speed for the CPU heatsink.

In short, the CPU fan speed is determined by the ACPI temperature, not the CPU temperature. And to answer your question, chikaslim, the maximum temperature of the ACPI is the max temperature of our CPU's, 95*C.

 

Holy crap, those look high--I hope that is only after some serious gaming

Fwiw,

I bought two of the np8662s that arrived today. After nearly an hour of installing Vista, updates and Office, temperaturs for the harddrives reach 61 degrees celcius on both machines and the palm rests became quite warm. I also ran a couple of disk scans and defrags to see how high they would go and they seemed to top out at 62 degrees.

After leaving the laptops at idle for a couple hours while the battteries charged, one dropped down to 47 degrees and the other dropped down to 49 degrees.

Any kind of mild activity brings it up into the low 50s--no gaming yet. I expect to see the temps climb a little higher once we start pushing the GPU temps up.

I haven't opened them up to take a look at the bottoms of the cases, nor have I altered the system in any way yet (search index is still running, no undervolting).

Other temperatures (acpi, cpu cores, gpus) seem about right.

This compared to a a flextronic arima whitebook, with an identical drive, which idles at 44 degrees and never gets hotter than 55 degrees.

 

Yeah.. I'm kinda worried about the temps. And if ACPI temp = CPU temp, that means my cpu is overheating too... Argh.
Granted I did do the extreme burn-in mode on furmark, but I heard the 8662 has good cooling, so I'm slightly disappointed. But I'm hoping that games will have lower temps though

 

I think I just found a satellite shot from space of chikaslim's laptop during a futuremark benchmarking run

Do you have a NP8662? So you're in the Philippines also?

You can buy a charger at Hot Toyz for sure. About the batt, no idea.

 

I wonder what will happen if he runs OCCT on his machine, haha.

 

@Soviet

Are you good with undervolting?

 

No. I am not good. I don't know how to undervolt a single thing on my computer.

What do you need help with, kevindd992002?

 

Well, I need help with undervolting a P9500 (has half multipliers) with RMClock. It just doesn't work for me.

 

My Corvette won't start. It is similar to a white car.

Are there any other details you would like to enlighten me with?

 

chikaslim's laptop was modded with MX2 and was supposed to provide cooler temperatures. It was done because there wasn't any T9900s on Sager's side and we were giving him a decent CPU.

Looks like we'll be getting the official GPU thermal pads and putting it in and we'll see how that goes.

 

Need to trick half multipliers by using the voltage for IDA (Intel Dynamic Accel) but turning IDA off after u've set the plan and voltages etc, so RMClock thinks that your full clock speed is actually IDA working.

 

Ok, here it goes.

It's just weird that using CPU Genie's voltage optimization wizard yielded a 0.975V for my 9.5x multiplier. But when I use CPU Genie and run Orthos, it seems not to follow the undervolting and still goes up to 1.075.

This is why I switched to RMClock (used the regedit trick to have 10x multiplier as a "normal" type of pState to trick RMClock in using 10x as the 9.5x max FID of my CPU) and set it also to 0.975V, but the problem is that it BSOD's. at 0.975V. Hence, it's weird they don't give me the same results.


ALSO, the problem with my P9500 is that RMC doesn't show me an IDA index, why is that?

What do you exactly mean?

 

I'm going to have to look into this one. I don't have RMClock installed on my machine, nor have I used it in quite a while.

 

Ok, just give me a buzz if you are able to do so.. What CPU do you have?

 

QX9300. 10char

 

QX9300 have V 1.050 locked as minimum. You can set whatever you want, but it will be still 1.050.

I have:
1- 2.4 GHz for v1.050
2- 2.53 Ghz for v.1.062 (BSOD on 1.050).

I've tried lower, CPUGenie will even show it's as lower, but in other tools you can see that nothing changed. Everything that less then 1.050 will be equal to 1.050.

 

Will SSD help in the temp dept?
I know they are still pricey but haven't heard of anyone having one in a NP8662.
They should help with temps right? No moving parts

 

how1er, please explain the registry half multiplier trick here.. It really doesnt work for me dude.

 

SDD's will run just as warm as HDD's. However, most SDD's have a greater heat tolerance of up to 70*C.

 

So besides the price scaring most people away, they do have a advantage of running at a higher temp with no problem?
That's great!
Hows the QX9300 holding up temp wise on your laptop?Does it get high during extensive gaming sessions?
