Project Freeze(M17/Ocz Whitebook)

yes. can you left your notebook about an inch and see. i remember the rubber piece is not big enough for airflow. it is then going to change. use bottle caps. at least on the back.

 

I had each backcorner propped about .7 inches (resting on my small screwdrivers) to help with airflow. Sadly.

This is why I have the Cryo Cooler on the way, I am ready to brute force the cooling. Also have all that copper I mentioned several posts up ready to go - just not as much time to tinker with it all.

 

yes i remember. but you should have seen better results trust. i did. i got a 10c drop on the gpu but i don't remember the cpu.

 

Ya trust me, I was a bit shocked when I looked at those numbers too.

BUT, now look at the FPS numbers in the top left corner. throws another monkey wrench into this analysis (way to go me holding all variables but 1 constant.....) My Min-Average-Max went from 1-4-10 at MSAA 4x to 1-10-11 at MSAA8x.....so maybe the GPUs are just working harder thus the higher temps offsetting the effect of the mod? I hope this is the case...Something to consider.

 

it would effect peformance and temps lol. drop it.

 

I'll run it now with MSAA x4 to hopefully have a "comparable" run to before the modifications. I will then run it some with x0 to see where it comes in.

For now, here is my latest run at 3dMark06:

This is only after 1 run, so i suppose temps could be higher, but beat my old best score by a wopping 4 points haha - so I had to post it

 

can you run furmrk now since you change your setting before?

 

Here is furmark at MSAAx8 and MSAAx0.

MSAAx8:


MSAAx0:


You can disregard the instantaneous temps on GPUs as these jump down when i exit fullscreen to show other windows.

Boy did my heart jump a beat when I saw the x0 temps.......aparently lower FPS is good in this "game" haha. As a side note, these were done back to back with cool down period, so IDENTICAL settings. Ambient room temp is 22c according to Logitech MX-5500 keyboard (it is a few degrees cooler than usual). As before, back is propped up and there are no extra obstructions to air flow. Even have power cored draped over the screen and down front of laptop so it isnt in way of GPU exhaust (you never know what will help.....).

 

can i see a picture of your cuts. i see not change in your gpu temps.

 

I didnt see a change in GPU temps either unfortunately.



As you can see, the holes should more than suffice for supplying air to the blowers.

 

i got to call it a night, but will be back on tomorrow.

 

ok no problam. i will sum up everything and see what's up.

 

UPDATE: I have placed an order for the spacers from onlinemetels.com,

I expect them to be here in a few weeks.

Questions.

The video card also uses the pading for the heat sinks right?

Would there be any beneft of removeing the padding and useing copper spacers there, so to allow better thermal disapation?

 

Wow, nice desktop.

Make sure you shorten them before you mount them.

I personaly am not going to use the tape, im going to peel the stick off the tape, then use AS5 glue,

I am going to try to post detail pic's.

 

when your qx9300 get there, you will see that the heatsink has two items to cool, the cpu and the acpi chip.

the problem is the acpi uses a cooling pad, which is bad. we need the pad cuz there is a big gap. about .5mm

the cpu uses thermal compound. this is good. we dont need a pad here, no gap.

the pad does not transfer heat.

but im not sure if that is the real issue with this laptop.

i personaly think its not as good as we all think it to be!

 

they should of spend two more weeks on the whitebook to be hoesnt. but they didn't so we have to spend weeks on fixing it.(it's kind of fun. )

 

halogod used mx2 on the memory and copper modded everything else.

but to me. i don't know how much heat the memory draws. so i can't tell you if it is a good idea or not.

 

qx9300 is installed!

running stock speeds 3dmark06 now

 

lets break some records.

btw your temps are going to be threw the roof.

 

that link you sent me with scores, those 2 scores dont match...in the main window and the result window. whats up with that?

 

where i just looked at it. if you are talking about 3dmark06 the main window that pops up and the on when you start it, if you have the advance or professional version, when you run it the first score will be in the background and then when you run it again, it will make the new score in the front, then it will erase the oldest. get me?

 

Who said that this will fix the problems withe slowing down on the qx9300?

who has tested this fix with a qx9300,??

 

im not saying that they make too much heat,

im saying that there must be a gap between the memory chip and the heat sink, and as a resault of that gap we are useing thermal pad's (in my laptop anyway) and those pads have a heat transfer raiting of 3-17, but copper is 380!

so, to transfer out the heat, (here i will ask you a question)

sould we use copper in place of any thermal pad's ? includeing the ones on the video card memory?

since I am opening the laptop up anyway to remove the thermal padding from the acpi chip and replace it with copper (or only add copper for those of you who do not have a thermal pad) it would make sence to replace all thermal pads in the laptop with copper!

 

adding copper in place of pads on the video memory can be good or bad. It will keep the memory cooler - which could lead to a higher stable VRAM overclock, but it will also put more heat into the sink which is otherwise "dedicated" to the gpu. SO you either open the window to higher VRAM OC and potentially limit the GPU OC or you leave it as it is. I am leaving mine as is although I think I will add the short ENZOtech copper sinks on top of the copper over the memory chips to help with cooling. Video RAM chips typically do not run hot enough to worry about. I prefer that the GPU get as much cooling as it can. Notice that on desktop cards with almost any aftermarket GPU cooler the memory is bare. And those are higher clocked chips than these, so i am sure you dont need to worry about them - isn't worth the trouble.

 

@scook9
your rase some good points. im not sure why your limiting such a small ammount of heat transfer (you claim the video ram heat to be negligable or small) so why not just let it out!

also, you say that your useing RAM heat sinks, this is a verry good idea,

I will also be useing ram heat sinks on my video ALSO ON MY CPU HEAT SINK.

I will put them (with artic silver 5 glue) on top of the ACPI chip, only after i shave them down to size so the cover will still fit.

 

it seems everyone answered each other questions as far as i see

 

Here is a collection pictures to show you what I have in mind (and I think you too - one of them is your picture haha)











The last picture is what I got to play with, I have 8 more pieces of the left group of copper than what is shown. I also got the Sunbeam brand so-dimm heat sinks on the way. The picture of the holes cut is what I have already done, and I will cut more after adding all these passive elements. Will probably have time to start on all this this coming weekend.
Will cut holes mainly over the ram and actual gpu areas (at least remove their "grill" patterns).

To give credit where it is do, the picture with blue RAM heatsinks applied was from HaloGod2007, the one with the shortened copper sinks was Axeman via a post by Dondadah88, and the one with the insane amount of copper everywhere was FNAKFHE

 

don't forget to put something to cover the holes

 

I will cover the holes once they are all in and i know what I am dealing with. if I do covers as you have done, they would be purely for protection - not sticking something like a finger in the fan. As those screens are not stopping ANY dust.

Also forgot to mention, my notebook will be sitting on top of a Cryo LX cooler.

 

yeah just makig sure. i did it so nothing big get sucked up in it.

 

sorry to flood you all with pictures, but here is what my back cover looks like for now and what I plan to do with the little heat sinks (overall and close ups):











As always, open to suggestions.

Also put 3 Scythe S-Flex fans into my Cryo LX cooler. GPU idle temps of 38 now!

 

what about the crossfire cable????? who is that going to fit. and how much heat do you think it can handle?????

 

From what I remember in physics and e-mag it wont be an issue at all as long as the insulator is not compromised. The heat shouldn't be any more than it is already.

 

are they shaved? they don't look like it.

 

no, that is just preliminary placements

 

soz you really made a lousy job with the back cover.....
you've cut some wrong places..... and should have cut other parts....
anyway don't forget to put a filter on the wholes otherwise it will be a dust magnet.
also try to put more on the cpu heatsink, that's the most problematic part, something like I did on mine:


anyway you have lot's of them. you can play around with them like lego. it's not rocket science.
just don't forget to add a filter.

 

So far I haven't added any holes that arima didnt already think was a good idea. I am planning on adding more around the two gpu sockets (mainly the slave).

As for the cpu cooler, did you not see I got a row of copper ones planned for it? Adding anything else would be pointless as the way it is slanted, would be filed down to their base anyway. But those in the picture with a vent right above for air will help cool cpu and nb (or at least thats my plan)

 

This is gay,

we need to design a new heat sink for the cpu and acpi chip!

ok, we have some more room in that area right now right?

so, we add 6 cooper heat pipes/tubes, and we use a pure copper sink, non of this metel/aluminum we have now.

then we use a new fan, more rpm!

i would pay 200 dollers for this!

i mean, i alreday spent 150 in VGA heat sinks,

..... this is gay.

 

First off, it isn't an ACPI chip, its the Intel Northbridge (NB for short). Second off, the cooling is NOT an issue in this laptop, we are just seeking better results than what Arima settled on. And third, to design and custom fab a heatsink would cost ALOT more money than any of us wants to or is going to throw at this.

The only short comings of the CPU cooler is that it is shared with the NB and that there is not that much surface area on the fins (compared to good manufacturers like Clevo - there coolers are amazing). The heatpipes there work fine.

So please refrain from comments like "this is gay" and try to stay productive

 

Productive?

I am the one who is doing all the vga sinks on the bottom,

look back a few pages, you will see it was my idea! (with the overkill on the heatsinks)

now, your talking about cooling is not a problem?

yes, this threed is now over 90 pages, and its about heat, how can you sumize that cooling is not a problem? lol

edit: ok, 40 pages

 

Yes there is heat, but the cooler on this laptop perfectly handles it without modification as long as you aren't overclocking, by handles I mean everything is kept within specifications.

They (the ones who began this thread) were also under the misconception that the stutter from quad cores was due to poor cooling, this has since been proven wrong. Not to say that cooling couldn't better.

I have actually read every post on every one of the 40 pages, so please don't lecture me on what the thread is about.

I do acknowledge the ideas you proposed and do think they are interesting and have a lot of potential, but do not think that you are the only person who has come up with this - see some of the pictures I posted of mods done by other users. Also, until you actually perform the mods and post pictures and temps, they are ONLY ideas. Although I really do hope that you get them done as I am eager to see the result.

I too have a considerable amount invested in parts for these mods, so believe me when I say I too am concerned with improving the cooling of this notebook. I detailed a few posts up what my plans are for cooling using additional heat sinks as well.

For now, here is a screenie of my temps before and after a vantage run both GPU and CPU are stock speeds;


I will run furmark some tonight and really max the GPU's with the cooling I have in place to see how they do now. Please take note of 2 things from the picture above, I know have a Qx9300 running at the same temps as a P9500, and my idle temps on the GPU are ONLY 37 degrees. The current temperature is idle after the run. The Max temperatures were generated during the run. The room temp as 26 degrees during this test.

After I get all the planned heatsinks in place, these should both get even better.

 

Hey everyone,
This is my first post here so let me say thanks to all of the guys who made so much headway. I read all of the original thread and all of the Project Freeze thread and am impressed by the amount of research and thought (expect for that one guy who cut his heat pipes, that probably wasn't the smartest thing to do.)

Unfortunately, this statement isn't quite true:

I am not over clocking; but, I am still running into the stutter issue so I've decided to go the copper mod route. Reading through the thread I wasn't able to find a definitive answer on the thickness used for the copper mod. Would anyone be able to provide me with the dimensions used for their Northbridge copper shim?

Thanks very much

 

they said to make it .5mm but for me it wold be minuim.

i think this thread should be moved to the alienware section now?

what do you all think????

 

I am running into the same problem. So Don, per the quote above you would recomend going with the 27 gauge?

 

i would go with the .54 to make sure the area is fully covered.

i don't think the .41 and thermal paste will be enough.

 

Thanks very much!

 

i got my copper sample pack here now

i see that .54 is a better choice

however it may not be enough.

also im thinking to make it a long cut. so it will wrap back up top of the heat pipes.

what do you think?

 

i would make it alittle bigger then your northbridge to cover up the whole thing. but don't curve it. you can just add heatsinks to make it cooler.

please let us know your results.

 

i used a tool that sheet metal mechanics use to bend the copper it looks like this

that is about the scale i used

 

don't forget to apply thermal paste to the NB and the heatsink.
