Project Freeze(M17/Ocz Whitebook)

they are quite new i think to the selling market ..... we can only hope we are only 2 GPU's away from # 1

 

here is my gpu heat sinks...i dropped 6c in temps

cant upload pics here wont let me...here are the links to them..i posted more in the alienware section

very very nice

how much you chargeing for those aluminum heat spreaders ....not the blue ones

 

Im going to go cut the heatsink tomorrow with a laser for metal.. i intend to cut it at the red line on this picture.. do you think the liquid will burst out even if i cut it with the hole facing up? I intend to seal it with some alluminium at the end that is cut than.. thougts zfactor?

 

I really don't think it's a good idea to cut the heat pipes, they'll never work as well as before even if you don't lose too much liquid.

 

MMMM. then what do you think we should do to separate the north brigde from the cpu?

 

That makes no sense.. if i dont loose liquid it should work just like before.. why do you think it wouldnt? I just dont know if i will loose the liquid or not.. thats what im asking.. if its a little pressurised or not?

 

i would NOT CUT those. im sure they are sealed a certain way and i agree they will never work as before, ill call a freind of mine tomm and ask him. he works for a heatsink company.. (zalman)

 

Someone should make a custom heatsink kit for this system (and possibly other systems as well). Killer Notebooks does this, but only for their systems.

 

Please do ask as soon as possible zfactor.. i only have the opportunity to do it tomorrow and on tuesday than not for over a week..

 

i argee about the custom heatsink that's why we made this thread. but so far it's alittle hard to mod the cpu as you can see. we have to wait for zfactor and see what happens.

what do you think we can do to improve cooling.i hhave some more ideas but on my phone my fingers are killing me.

 

Whell im going to sleep now.. please give some more info on the liquid in the heatpipes soon zfactor..

 

he replied to me in email and said DO NOT REPEAT DO NOT CUT THE PIPES!!! he said you will never get them working right after that and not only that but think about something else you are shortening the pipes. the quad already runs hot and your will be removing surface area of the pipes so most likely cpu temps will rise. also they cannot simply be "closed" he said you need to either silver solder them or find someone who can braze the copper back together. he also said there would be no way to make sure you didnt loose any of the "liquid" in the pipes after cutting them.. he basically said in big caps "do not do this unless you have the facility do properly do it" he works for zalman in their engineering dept..

 

well the cpu temps would rise ... but it would seperate the cpu and the NB but the fan in the NB will help pull off heat

 

mr moo then that will lead to unstability.


well what we can do then is some material that will separte the heatsink from the nb by 5mm and use some type of heat sink that will go out somewhere. get me.

 

like Z factors idea

 

oh yeah. i forgot he did say something like that. Lol.

 

he is getting it done now lol

 

as long as he can do it. which i know he can. we just have to wait and see what happens.

 

i prolly will be selling if the new laptop has smart bay and binary GFX

i need more battary alot more lol i will go with basic config and upgrade my self ... sorry guys imma be selling if it is


i got 1000 for all my grad money so im good

 

no i understand. i was thinking about mines for the w90 but my computer is awesome. i can bios overclock the cpu. and more but i can't think of it right now.

 

i got the heatsink cut out already i dont think it will be any issue. like i said go out and around the heatpipes...

 

ok good to hear. here is a album off the back off i made so you can show us when your done since what happend before
http://tinypic.com/useralbum.php?ua=PVSdULk1grrKQzF92a9gjg==

 

yeah just have to buy a new camera now.. sucks i paid like 300$ for my one she lost. was a awesome camera

 

Does a custom metal working an modification facility count ? My friend owns it.. hes got everything from laser cutters, all kinds of soldering (including silver) materials, mechanical benders, CNC machines, etc.
I already have the replacement here and i basically have nothin to do with it.. so i think im just going to go ahead with the plan.. Ill ask my friend how he suggests to do it.. hell know hes been doing this his whole life..

 

up to you but he said it will never perform the same again..he was talking about a lab setting

 

Whell thanks for the info.. ill tell you how it goes..

 

oh no i dont see this workign out good

 

The coolant in heatpipes isn't just poured in there like in a bottle it's filled under pressure with the air vacuumed out.

Once air gets into that pipe it's cooling is worthless.

 

there are less than stellar ideas about to go down in this thread....

 

yeah there is. i'm copper modding right now. i just need to getting it straighten out and then i'll be good.

 

hammer time

 

Lol i did and i'm done. i can't run prime95 for some reason. it keeps on not responding.

 

lol run orthos

 

ok i can run cpustabtest which i heard is the same as orthos.

 

OUCH!!!!!!!!!!!! it's warmer now(room temp) then when i last tested it. (2nd page. i am going to cut a hole at the bottom of the laptop and see what happens. also i have to reapply thermal paste because i didn't really put any one when i took it off, just put some on for testing purposes.)

 

ALWAYS put thermal paste on and cut slits onver the cpu fan .....Arima was retarded when they cit them

 

6C is really a LOT just with those small heatsinks. worth to do it. I had the similar idea of putting some on the CPU area but without expectations but temps only dropped about 2-3C.

What I've learned so far:
1 without a new heatsink design there's no real mod where we can get a real difference. don't except miracles or more then 10C temp drops.
2 cutting heatpipes is not a good idea.
3 a small fan is not the solution, tried it, the space is too tiny to fit even a very small one.
4 a copper heatsink mod is the way to go (no silver or aluminium or others)
5 a large copper block will not work, the heat will concentrate, it needs to dissipate the heat, it needs some fins.
6 small wholes in the chassis in the cpu area will help a bit
7 a very good thermal paste will help another bit

cooling the whole CPU area maybe is not a good idea because the heat will spread to the northbridge, maybe just cooling the northbridge will bring more benefits.
Considering all the above I suggest you to search for notebook heatsink mods, specially the killernotebook: ones example1 example2. it will give some good ideas for modding this one.

 

ok i am taking a lot and see what i can come up with.

i know the north brigde is going to be hard to cool with out modding the heatsink and also i argee with you meaning that we have to get a new heatsink.

 

wooooooo 190 for the CPU is smokin! gonna have a barbecue there, with a side of "chips" lol

 

Lol. i know. i hit 90 alot even when i am at 3.06ghz. i don't remember 2.53ghz but i think it is 10c lower.

 

ive had my quad hit 98c once when it was really really hot in my room...ambient was like 82F and was running 2 instances of dual core orthos....chip is still alive...i believe you should start worrying when it goes above 95c...ur not going to have this chip long enough where the heat would matter to you...it may only last 5 years instead of 7 sort of thing....and i know for sure we wont have these notebook for seven years unless our qx9300's can handle games and ati keeps making cards that fit our chassis( fat chance since tech will be way diff then)

 

solutions:
1 new heatsink
2 heatsink mod with costume copper plates
3 modding other copper heatsinks and apply it over the cpu heatsink

1 I don't have knowlage and technological means to do it
2 I don't have a design neither I'm capable of designing one so I can't make it
3 After a lot of searching I found this: http://www.enzotechnology.com/air_cooling.htm
they make many copper heatsinks, ram and mosfest and if you bend and/or cut some it will fit and it will work. There are many other brands and heatsinks. Of course no miracles but with a good thermal paste and a few wholes it will drop some degrees. Also if you don't make any wholes you still have a warranty.

 

nice find. i am on my phone so i can't check the website as i would like to. but i will and post what i think is best fit for this notebook. unless someone has a better idea and or does it before me.



any updates guys?

i copper mod my notebook on the northbridge. but i installed a bad driver. i really bad one. i keep blue screening and when my external is plugged in threw my e-sata i stutter. the error i get is jraid.sys and i am going to see what's up. i get lock ups and it's pisses me off. i will also post this in the quad problem thread to see if anyone also has this.

 

Hello again guys.
I had the pipes cut, there is NO LIQUID in them.. i was there when it was cut. The inside is grainy and i think it has some magnetic properties.. I am not sure how exactly it is supposed to work.. There was no pressure in them either.. no gas leakeage to be heard.. I tried to seal the end with silver zynk (not sure what it is in english) - the material for sealing.. and it wont stay there it just falls off.. so im prolly going to seal it together by applying pressure to the open end of the pipes so they seal together mechanically.
Will post some pictures later when im done playing around with my expensive toy, if it is successful or not.

 

How heat pipes work.

The grainy substance is in the pipes to promote evaporation and condensation of the coolant.


For those of you with an uncut heatsink try adding surface area to the area on the pipes between the CPU/GPUs and fan. Heat is drawn to the colder areas of the pipe and the faster the heated coolant is cooled the more heat it will pull off the CPU/NB/GPU.

On desktop heatsinks the bulk of the surface area (the radiator fins) is located where the pipes are being cooled, not where they are being heated.

 

correct the grainy substance you see is the "wick" which acts as storage for the moisture some say its has a "capillary action". the liquid will not pour out but the pressure in the pipes is set by "vapor pressure of the working fluid" so you would not have seen it pour out. you may not have seen any liquid at all unless the heatpipes were still hot and there was any condensation in the pipes themselves..

 

Just noticed there are at least two different versions of the GPU heatsink.

Heat pipes are side-by-side.

Heat pipes are stacked at different levels.

Fan looks shifted up and down in each as well....or the first is thicker than the second.

Wonder if one cools better than the other.

 

no they are the same heatsink. the bottom pic where you think they are stacked the one pipe has a black sticker over it.. trust me i used to be a reseller for them...

 

Ahh alright. The black tape looks like it sweeps up making that the exposed pipe seem higher than the other one and the numbers on the stickers are different.
