Solving the 5672 Heat Issue

i've read the whole thread...just bought for few months.looking forward to cool it off...sori for nub question as i dont understand english that well...
1) should we removed the dust plastic cover?which is better?
2) should i put the heatsink at the chipset?just stick it with the thermal sticker provided or use adhesive thermali paste or AS5?

 

Do not remove the plastic dustcover. it provides the airflow through the laptop. if you remove it, your lappi will get hot under the touchpad.

and i cant answer your second question as is didnt try it myself

 

Hey guys...

Finally, I'm getting close to making the ACPI to work for NHC...

But I'm veeeery busy and I would like to know if any of you can give me a hand...

I need to know the name of the devices and (if possible) the values that are used to change their values.

I'm attaching to this reply the a fragment of my still not functional ACPI configuration for 5672.



The only purpose for I upload it is to show you what do I need.
Can you see that "_SB.PCI0.LPCB.EC0.WLAN"
It exists on 5672 but it's not responsable for turning the Wi-Fi LED off.

I'm not having enough of free time to research it right now.

 

Someone Help The Man!

 

After reformating my computer and reinstalling xp home, my fan does not turn on at 55C anymore. It regularly idles at about 63C. Anyone now what program to use to get the fan to turn on at 55C again?

 

as we mentioned previously, go help someone write the apci control settings for the 5672 with C++


Basically this means no... in case you didn't catch that

--ssx--

 

I did alot of the stuff in this thread and these are the results.

1. Used the Thermal Analysis tool. CPU was running around 75-79 C or higher after a little while at idle.

2. Used arctic silver and removed all of the heat shields. No difference at all maybe 1-2 C cooler if that.

3. Cut that little notch in the fan. Notebook has been running now for about 16 hours and it hasn't got above 56 C. This was the huge one. My laptop is over a year old so it is already past warranty.

4. I ordered an Antec cooling pad, hopefully it will drop it even more by just forcing some more air past it.

 

But isn't the palm rest, keyboard, and especially the touch pad smoking hot now? That is what happened to me when I cut the notch out and boy is it not worth lowering the cpu temperature.

 

I purchased my Acer 5672 in April 2006. It's a great laptop, but when using it all day, every day, at work, the temperature of the touch pad and wrist rest area were unbearable. Following the various steps from the thread here I've had the following results:

1. Applied AS5 - Was hitting mid-70Cs at idle, and high-80Cs when only at mid-capacity.

2. Re-applied AS5 - Same results.

3. Cut a hole in the side of the fan plastic, removed dust from within the heatsink, and reapplied AS5 - I am now using several applications, after several hours work at 48C, HD at 46C.

I tried everything, and the best result has been removing the fan plastic. It was a painless process and I recommend it to everyone having heat issues. My touch pad, and wrist area are now cool and manageable, and there is no burning smell now... And to think, I was about to buy a new laptop.

Thank you everyone who has offered input into this thread, it saved my laptop.

 

So you last two that cut a hole into the fan shroud, did you keep the vents covered above the fan or uncover it. I have never tried the hole in the shroud with the vent still covered. I know when it is uncovered is when the palm rest is about to ignite into flames. I covered up the shroud and the vent with high temp electrical tape so it moves air the way it does new out of the box, but I can remove the fan shroud tape quite easily if you guys say you kept the vent covered.

 

Do you per chance have before and after pictures? My Travelmate 4403's drive idles at 53'C and I want to try get it down, even removing the HDD cover doesn't help much.. I'm wondering if the FAN is not sucking out the hot air from the hard drive properly, and I've cleaned the fan.

CPU doesn't get hot, just the hard drive under the touchpad

 

Hey.
I just installed the new version of notebook hardware control. but now it gives me three different cpu temperatures. the one, wich is shown in the main nhc window an was my cpu temp in the older version is named THRM, the other ones are named core#0 and core#1 an they are always about 5°C lower than the THRM temp. so the real core temp seems to be lower than we think, but can someone tell me where the THRM temp is taken?

 

oooh. so NHC has updated something.
But can it be used for any fan control yet?
THRM temp could be the temperature of the heat sink attached to the fan? the heat sink delivers heat not only from the CPU.

winter is gonna be coming soon here in Canada. The extra heat from the vent is a good hand warmer!

 

no fan control without an ACPI script...

 

Hi,
My idle CPU temp is around 75 and everytime I play a more demanding game (company of heroes for example) it overheats and shuts down.

I just read the entire thread and it seems to me that most effective way to cool don is to "Cut that little notch in the fan". Does anybody have some pcitures of the procedure?

I am also planning to get a cooler pad.

thanks,

 

best option is as follows.

Read up, and replace your compound.

From there NHC helps alot as well as turning off un-needed stuff.

 

We still need some way to increase the fan speed.

Everything, and I mean everything, on this thread would be more effective if you could up the fan speed.

I am getting ready to give up waiting for a software solution, and just hard wiring a potentiometer of some kind between the fan and the 5V on the USB port.

The fan is a 5V fan, and my tests showed that even the fastest the software runs the fan, it's only giving it 3.5 volts.

When that sucker is hot and dying, you no longer care about noise and battery life, you just want it cool. Airflow is our only true hope.

 

no you are wrong here PRH we don't need a faster fan, we need settings to control the fans manually so they don't turn off when we don't want them to.

 

That was a stupid thing to say.

Sorry you are wrong, idiot.

Answer this smart ass: When a fan is stopped, is it running faster or slower than when it's running?

Just get your ass to work fixing the problem and don't say stupid remarks like that. And quit wasting your time with stupid pastes.

We need more fan.

 

Show some respect for those who are trying to help.

 

You guys have me thinking now, what do you think of a fan override? I have the 1400 version with an uncovered vent, the touchpad is hot but doesnt really bother me, but I'm always up for a good cooling mod. When I get home tonight, I'm going to cover the vent some to help with the touchpad issue, but I'm also thinking about finding a 5v lead, and mounting a small switch in the blank PCMCI cover, this switch would switch between system managed speed and manual 5v. This way the computers battery life wouldnt suffer, but could be cooled appropriately when gaming or just on AC power.

Any suggestions or thoughts against this method?

 

the best solution is to write the C++ apci table so you softmod control it. There really is no other clean way.

 

Get your 5v from the USB port.

I already run a 2 fan lapcool pad from the USB's, so the internal fan wont tax it.
