5930G cooling solution?

MysteryE

I think there is a thread around here on how to make a home-made cooler for notebooks.
So I suggest you use the search function.

Although ... you know what would be interesting?
The Zalman was made out of pure Aluminum.
If it would be possible to create at least a lower section of the laptop out of pure Aluminum, I think there's a good possibility it would reduce the laptop temperatures even further.

But also, Zalman can be rather heavy ... true, not much, but still, it would probably increase the notebook's weight by another kilogram or so.

 

i wouldn't mind that ... and it does seem a good idea... hmmm... wonder where i could order something like that... and how much it would cost...

mysteryE i dont have the original anymore i threw it away when the vent broke...

 

Aluminum is also another word for Aluminium.


There's an Aluminium Sheet 1000mm x 250mm x 1mm on ebay for only £7.10.
Prices vary and go up to £13 per sheet.
So I wouldn't say it's too expensive.

Tricky part would be making the sheet so it conforms to the lower part of the laptop (but given the fact it's mostly flat, there shouldn't be a problem).
Of course you'd have the original plastic one as a base ...

I mean ... home-made chassis might be a problem after all ... so if an individual would attempt to do something like that, then making only the lower part of the notebook for that would effectively be prudent.
And I don't think it would be necessary to do it for the entire lower part ... just for the areas that contain vents ... which further reduces time in construction process.

Hm ... then again, copper might be better in terms of being resistant to heat.

Now, I'm only theorizing ... but there's a possibility that if something like this would actually be done ... it just might help absorb and reduce the temperatures by several degrees.
I could be wrong though.

 

I see.
I'll look around first then.

For me, the cooler isn't for mobile. I'll use Snap Ball instead if I'm in mobile condition. The cooler will be used in my home only, or if I have to use the notebook for quite long time non stop.

hyeclass:
ah that's just too bad...

 

Stop...before you guys go and buy a whole lot of expensive materials to build a cooler......let me post a pic or 2 of my homemade cooler.

Will take photo's and post them tomorrow evening.

Simple, effective, cheap and made for Acers

Cheers,
Theo

 

i'll be waiting... but for now the alluminium seems like a good idea...
altho just read on wikipedia that copper is better then alu but more expansive...

 

I was referring to using aluminum or copper to construct lower parts of the notebook with vent exhausts and thus replacing the plastic ones we presently have ... not to construct a cooler (although it can be done for such a purpose as well).

 

I'll be waiting

Copper is better than aluminium, huh...?
Hmm...

 

i just googled a bit and it really is better for heat transfer... thats why al heat pipes are made out of copper...

still waiting on teejay's pics

 

So ... apart from constructing a home made cooler ... would re-constructing lower part of the laptop out of copper for example (and using it in place of the more plastic-like casing) help in further reducing the temperatures?

When I say 'lower part of the laptop' I am primarily referring to the parts that only have exhaust vents.

 

i think so... when gaming without extra cooling you should see how hot that lower part gets .. you can cook an egg on it

then the air that flows in to the vent is also hot i think....

you get like a hairdryer effect....


thats what i think happens i'm not a pro tho....

 

It's not hot enough to cook an egg on it ... but quite warm nontheless.

Without Zalman cooler the temps are within 80 to 82c for the cpu and about 70 to 75c for the gpu (under load).

You know ...
It would be interesting to see the effect of pure copper notebook chassis.
The interesting part is that copper really isn't that expensive, plus you can do it at home if you have the necessary tools and are skilled enough.

The only tricky part I see with it all would be shaping the copper to the proper design.
The lower part of 5930G is not the problem ... the upper part on the other hand has a creative-ish designer's touch to it though.

Question is ... if reconstructing only the lower part of laptop with copper is essential ... then just how big of a decrease in temperatures are we talking about exactly?

Zalman is made out of pure aluminum ... and it always has a cold feel to it.
But it's also somewhat thick on some parts ...
So given the fact the exhaust vent 'panels' that cover the cpu/gpu/hdd/ram are relatively thin ... the same thickness should be applied to the copper replicas.
Just how much of a gain in reducing the temperatures would it be approximately?
A few degrees is really nothing to sneeze at ...
5 to 10 degress is actually progress, but at the same time I think we should expect little until someone actually does it.
My father is rather crafty and has virtually all the necessary tools.
So I'll consult with him on the matter and possibly give it a go if it's a realistic option (which most likely it is).

Edit:
Small problem I failed to anticipate ... wouldn't copper panels with exhaust vents also produce magnetic fields when other components inside the notebook are concerned?
And if so, just how would that affect the notebook in general?
Would it have any effect at all?
But if that was the case, then 'copper mods' (that involved putting small copper sheets directly on the cpu to decrease temperatures) made by some individuals would have failed, would they not?

 

OK guys. This prototype might look like a POS. Reason being is that I intended it for my own use only. And therefore was slapped together (and I mean slapped together) in about half an Hour around three Months ago.

I had got really tired of the cheap Chinese coolers I was buying on a regular basis. The last one I had failed also (noisy fans) and there was no way I was going to try and rebuild another one. Had enough.

So I grabbed stuff lying around. And used it.

The only part that costs any money is the most important one. Namely the fan. Available here: http://canada.newark.com/98K9075/supplier-direct-ship/product.us0?sku=bisonic-4c-230hb-t

So, before you folks laugh at this cooler....remember that it's a basic item intended to push air up and around the base of a lappie that uses and compliments Acers airflow design. Namely cool air pushed up into the base of the lappie.

No Aluminium used here. Just deritives of cheap wood. Cheap as hell.

In spite of the (wrong materials) like hardboard...this cooler has lowered my HDD temp by at least 10 to 15 Degrees Celcius. For me the most important one.

A bonus is: my CPU fan rarely turns on at all anymore when doing Internet surfing or simple tasks.

In fact, the whole lappie runs cooler. Lots of air being forced under it now.

If you are brave click the thumbs.

 

where are the thumbs

 

Tired of trying now. Keep getting message: " 413 Request Entity Too Large."

Don't know what's happening here

Will post photo's when I can

Cheers,
Theo

 

thats what i'm thinking too but maybe if you just spray-paint the inside? dont know.... apple has alu casing and everything works allright there i just asked some people and they said it has a rubber layer(very thin) on the inside any ideas??

 

A thin rubber layer is probably there to act as insulation ... or at least the sprayed paint would do the trick as well.
Need more info though on what would be more effective and how exactly to proceed.

Mind you for now I have no intention of actually DOING it, just working out a theoretical concept.

 

i'm actualy thinking of doing it.... if it would work i'm interested in seeing how much difference it would make.... maybe i'll give it a try tomorrow...

 

Oh well....got the pics and I am still not able to post them.

Patience is a virtue I suppose..

Theo

And BTW, lappie HDD is at 40 degrees Celcius now after being on the internet for about 5 hours. In hot weather. Without cooler would be around 55degrees Celsius. Or warmer/hotter.

CPU fan has yet to turn on. CPU consistently at around 40 to 45 degrees C.

Go 7600 grapics at 47 degrees Celsius.

This Acer is loving this.

Edit: Image links (at last!!)

 

Images posted.

 

thats very nicely done

how about your gpu? because you fan is in the middle but gpu is in the upper left corner... how areyour gpu temps?

thnx for the pics

///oops didn't read well sorry

 

Arctic Silver 5

Cost: $7-$30

Time: 20-40 minutes to apply

Difficulty: Hard

Applies to: Advanced users

Arctic Silver 5 (AS5) is a thermal compound made of 99.9% pure silver. It can take off up to ten degrees from your CPU, which is substantial. Keep in mind that this isn't the easiest option, but can yield excellent results if done right.

Before you buy AS5, make sure you can get direct access to your CPU. If you cannot, then this step is not possible.


(view large image)

A view of my notebook's CPU with the heatsink removed.

Turn off your notebook, unplug it, and remove the battery and bottom compartments to access the CPU. You may need to remove the heatsink or fan assemblies above the CPU. The rest of the procedure can be found on Arctic Silver's website in thorough detail, more than I could type up for you here. Link to procedure.

After allowing the Arctic Silver 5 thermal compound to set for the recommended 200 hours, I have seen a 3 C drop in temperature -- it gets better over time. Up to seven degrees can be taken off.

I also noticed a difference in the amount of heat put off at full throttle. My notebook's fans do not come on nearly as often as they used to because the peak temperature is lower by 2 C.

Quoted from Chaz

10 degrees drop not bad. you can try this i guess, if you know what you're doing

 

Thanks hyeclass

Here was the original half hour slapped together thing:







It lowered all temps significantly.

And I would not have bothered spray painting or improving on it if I had not opened my big mouth and posted a promise here of pics.

Well, it probably still looks like a POS even with the makeover. But it works even better now with the added air intake at the bottom of the unit.

And a properly cut out top fan hole (bigger and not so "just cut a hole/square - good enough" slap together attitude)

And of course a grill over the fan. Handy for keeping your fingertips when moving the lappie and the fan is still on.......

Cheers,
Theo

 

Forgot to mention:

The keyboard of the lappie now sits at angle which is perfectly suited for typing, gaming etc. For ever. It's like using a normal PC keyboard.

No more numbness anywhere anymore.

Cheers,
Theo

 

That's nice!
I'm interested to make one too..
Can u tell me the step to make it one by one?
I can ask my uncle to make one.

 

Help you anytime.

No Zalman this though.....

Cheers,
Theo

Edit: I will post the dimensions tomorrow (I have no ruler or tape measure here know)

 

Try using some sponge on the under side stuck on with some wood glue.
That makes it more comfortable when you have it on your lap.

my home made cooling pad is a year old now and still works great.

Just a thought
Phil

 

Good tip - thanks Hoggie although the cooler is mainly meant to sit on my desk. I don't move it around much.

Where you been lately ???? Miss your help here. I hope all is well.

Cheers,
Theo

 

all is getting back to normal here now mate, so will be back in to full swing in a couple days

Its nice to be back
Phil
