Project Freeze(M17/Ocz Whitebook)

no so i can send it back in in case of a MOBO failure



ok there is 1 fan i could find that will fit with the bottom on i measured it out
http://www.rcslot.com/pc-radio-control-slot-cars/INT2900.html

pretty dang small 30x30x6

i set my 50x50x10 over the NB/CPU heat sink and dropped it by 10c....

i may try under volting ... but after i get AW crap off i will be good i think .... Silver Mod NB Cpu ,GPU's memory chips basically everything

 

Yea silver is better in terms of thermal conductivity as copper and gold is worse than copper even so no point in using it.. Only better thing would be diamond .. but i dont have that lying around.. i do have silver sheets however so tomorrow when im getting the new heatsink im gonna make seperate silver moded cpu and nb cooling and perhaps even sb.. i dont have any mini fans though so the seperate nb cooling will only be passive.. ill just cut some holes on the back to allow a little circulation.

 

if you line up the cpu vents on the bottom you will find they SUCK and half the ent is blocked i reccomend modding that so the fan can really suck in air

 

I just found a shop that sells 20x20mm mini fans. But now i dont have an idea where i could power it..
Suggestions? Hallogod how do you plan to power yours?

 

he is prolly gonna use usb power like before

20x20 is perfect ... but it has to be under i think 7mm THICK to fit with the back on


silver will offer like a 10-12% increase in thermal conductivity who knows just yet we shall see ... imm get some good thermal paste and use silver

http://www.heatsinkfactory.com/ic-diamond-7-carat-thermal-compound-15-gram-p-16605.html

no way in poo you could stutter then

 

Ive looked over the results comparing as5 vs ic diamond and mx-2 vs ic diamond.. and they are not so convincing.. some are having a bit better temps, some worse and some the same.. so im not going to bother getting this paste since id have to order it from germany..

 

The fan is 12v so its out again and back to passive..
But if you look at HIS TEMPS with the mod i intend to do its more than sufficient.

 

with mx2 use very little. i can say for sure its as good if not better than as5 is.. all i use now.

 

so it looks like we are going to try the silver mod 1st then. that's fine. i have to find some then. i was going to get a heatsink off a old desktop and cut it and shave it and use that for now. but i wonder if home depo will have silver.

also for halogod. the back will have to be moddified. the cpu and the gpu fans and everything is covered 100% with very little breathing room. i think they did this so if you put it on a dirty surface nothing will get in it. but i think cut a little square ofa mesh will do the trick.

ok. i think i may have to much mx2 on my cpu then. i will have to do it all over.

i don't even know why the made the southbridge on the gpu heatsink????? no wonder why we are stuttering.

ok i have been say this for a while but i want to change the fans on both heatsinks. there must by something better out there.



zfactor did you try the heatsink mod?

 

Actually the area your marked green is the PLX chip, which controls Crossfire/PCI express 2.0 bandwidth. The southbridge is on the other side of the board (I saw it when I removed my palmrest).

Also, another good compound to use would be Noctua NT-H1. Got better results with it compared to AS5, and similar (tad better) than the MX2 I applied to my HTPC's CPU.

 

if someone get me some CAD draws I have access to a CNC machine so I could make some nice heatsinks...

this site can give you some ideas: http://beta.ivancover.com/wiki/index.php/Eee_PC_Internal_Upgrades

 

really. that is the green marked area. so if we happened to get it cooler, do you think it would improve our system overall?

you lost me. can you explain alittle better.

 

well I don't known what you didn't understood... http://en.wikipedia.org/wiki/CNC_machine
http://images.google.com/images?q=cnc+machine
I use CNC machines at my college. I could try to make an heatsink if I had some CAD http://en.wikipedia.org/wiki/Computer-aided_design draws. IE, a better cooper/silver heatsink to cool it better.

this is about powering a small fan. HellCry asked about it.

I also thought about just a small silver heatsink, I don't known if there are any on the market because what I found was just silver colour (aluminium).

I've moded some cooper heatsinks in the past but I never worked with silver. It seams a bit expensive... and I don't have a clue where to get silver blocks to work with.

About thermal compounds.... there are no miracles... even with the diamond one or with the liquid metal one. I've tested many compounds in my desktop. Never ever I got more then 5ºC cooler at best.

 

cooler couldnt hurt but i dont think that is the issue

 

x2 I really doubt that heat is the problem. But just to be sure someone should measure the temps with a IR thermometer.

 

silver only offer a 10% boost its not worth it ....

the silver is a good idea but ktron made me think for a sec even if we put silver on there it will draw the heat a lil better but the copper still will only be able to draw so much off the silver so its like down throttleing Ram lol

imma get a PURE copper stick my chem teacher can order pure elements ..... copper may be just as expensive ...(im talking pure)

 

I had to register to dispell some misinformation in this thread. (i felt obligated since i'm about to the pull the trigger on a newegg OCZ whitebook).

First, about me:

I'm PhD student in Mechanical Engineering, so I've got a pretty decent background in materials and heat transfer.

So, let's talk about this idea for using silver as a heat sink:

Short answer: it's a horrible idea.

Long answer:
you gain a marginal increase in thermal conductivity using pure silver over pure copper. (~420 W/m-k vs ~340 W/m-k). Silver is also not machinable, thus you can't machine fins into it and that right there negates its use as an effective heatsink. Next, pure silver oxidizes extremely quickly and it's ability to convect heat to the surrounding air drops appreciably. In order to prevent this oxidation, you need to use an alloy of silver. The downside to this alloy is that it will have a lower thermal conductivity, bringing it to the level of copper, but for much more money. (it still wouldn't be machinable).

Now, let's talk about copper. Copper heat sink material is great. Pure copper is not. Again, pure copper is not machinable, and it oxidizes, presenting all the problems stated about. The copper alloys used for heatsinks however, ARE machinable, AND retain most of the thermal conductivity of pure copper (because they are very lightly alloyed), and they dont oxidize as readily as silver.

Moral of the story: Heat management systems designers are engineers and choose the materials they do because they are best suited for the job. If you need more cooling on the northbridge, use copper.

 

i should add:

If i convince myself to pull the trigger (with qx9300), I will evaluate the system when I get it (verify stuttering etc..) If it turns out to be a thermal management problem, I'll see what I can come up with as a solution.

 

i was only talking about thin thin peices of silver between the heat sinks and components i would never make a silver heat sink lol

also thank you for your help

and the pure copper is to help draw away heat

 

i think its best we first cut vents on the m17 cover so that the cpu fan is isnt half blocked

 

yea that would be nice

 

if your wanting the thin piece of silver to help carry heat to the heatsinks, that also wont work.

The amount of heat a material will conduct depends only in part on its intrinsic thermal conductivity. It also depends in large part on the geometry of the material. Given that the distance you are covering between the two components is fixed, the heat conducted will be linearly proportional to the cross sectional area of the conductor.

So if you have a very thin piece of material, that denotes a small cross sectional area and thus it wont conduct much heat at all.

Also, you may or may not know exactly what the mechanism is in those copper heat pipes. There is actually a low boiling point fluid in the pipes. The function by boiling the fluid at the heat producing component, which causes the vapor to flow towards the other end of pipe (the heatsink) where it condenses and repeats the cycle. Because the enthalpy of vaporization of fluids is relatively high, this is a much more effective cooling solution that a plain air to air heat exchanger. What you don't want to do, is saturate the the heat pipe with so much heat that the working fluid is no longer able to condense at the cold end (where the fan is). If this happens, the fluid cycle stops and the efficiency of the system as whole drops significantly.

I haven't looked at the pictures in detail, but we will probably be better off with a small air-to-air standalone heat exchanger for the northbridge.

 

thanks for clearing that up but copper mods do yeild results , very small ones though. I am very happy you are here now

how ever small i would do it

 

ok we are working on two things then trying to make the notebook have the same results when the back is off and also to do the copper mod correct?

 

just pulled the trigger:

the specs are:

OCZ whitebook (obviously)
HD 3870 crossfire
QX9300
4GB DDR3 1066
2x WD scorpio black 320gb 7200rpm

 

and just as quickly, I cancelled my order.

After reading the horror stories over at the OCZ forums and seeing the OCZ say that we're all basically SOL, I bailed.

 

Well, it isn't so much, "SOL," as you still have a full warranty. What is lacking is BIOS/Driver updates, but those are coming via AW in a pinch or most likely asi, the new distributor of the 840 chassis.

 

yeah sccolbert why would you cancel your order. ocz will still have full 1 year support and you can still get driver updates from the real sites like intel, ati, etc. bios is the only thing we would not get until asimobile starts there production.

 

here is a fix for the gpu's provided buy axman

 

Hi Guys. I had almost made a decision to buy the W840 with QX9300 and Crossfire HD 3870's and then came across this thread. How endemic is the overheating problem and does it affect those who do not overclock? After I buy I am not going to be in a position where I can just send it back. I accept that "lemons" do exist and nothing is perfect but if the computer has a known overheating issue when it is operating at full throttle, and why else do we buy computers like this if not to be at full throttle , then I think I will stay clear and buy maybe the D901C or W90VP-A1.

 

well the gpu's arent to bad. it is the cpu. some don't have problems. this thread is to make it as cool as possible. i do not want someone to say there not going to buy a nice system because of a thread i created.

i am up for alittle more. what test do you need to be run so you can make your decision.

 

the system doesn't over heat bad its just because the NB is attached to the CPU ... and that causes very very small stutter. I don't stutter

i mean is gonna get warm when you have 4 cores running at 3.2 ghz ....

 

Awesome, thanks guys now I can purchase the QX9300

 

im done creating vents for the part of the cpu fan that had no vents....temps seem to have dropped 5c on the cores and 2c on the NB....not too bad considering its getting twice the suction now

 

Yea that could have fixed the stutterin alone

 

Thanks for the offer dondadah88 and don't get me wrong I am not writing the W840 off but I am being very cautious, hence my question about overclocking and how common is the problem of overheating. I have no intention of overclocking but I do want to play Far Cry 2 etc at the highest resolutions and detail. What is the stutter we are talking about, video or what? My final decision was between the W840 and the D901C and the weight advantage of the W840 had me leaning that way.

 

d910c isn't that the one with an I7?

why not wait to the m98? the i7 is for code crunching not gaming ...the M98 is quad with dual 280m gtx

the stuttering is not common .....couple guys who just re-applyed paste never had it

 

Just got the new heatsink with the fan it seams the seller didnt know it included it.. and im going to get it laser cut this afternoon..
If silver is so weak than perhaps ill just use the copper..
And axman how did you make the ramsinks stick with mx-2? Its just a paste.. it should fall off right? Or did you leave the original pads on them and just stick them on with that? And did you put mx-2 on the gpus and ram chips or not?
And can someone give me a link for those ram heatspreaders?

 

silver isn't weak..... it will draw the heat better but you can't make the copper draw the heat from the silver so its liek putting 1333 ram and then it just downclocks to 1066

newegg should have some

http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&SubCategory=572&N=2010110572

 

Whell i found it in your link
I just cant find any seller in Europe.. i cant order from newegg..

 

get some desk top ones and cut them then

http://www.frozencpu.com/cat/l3/g40...sinksCoolers-Passive_RAM_Heatsinks-Page1.html

 

This site CAN send to Slovenia
Thanks!

 

whoooo ur welcome

 

95$ to send though ...
Id buy a desktop one but theire totaly different size as far as i know they are longer.

 

The D900F is the new one with the i7 but it will only have a single 280M card not the SLI 9800m GTX in the D901C. What is the M98? I haven't heard of it but dual 280m's sounds good.

 

lol its this

AMAZING this is outside

inside here

 

That is one shmicky looking laptop. I feel like I must have been living under a rock not to know about it. Do you know when it will be released?

Sorry Guys I am off subject here. Thanks for the info and I wish you all success with your cooling.

 

this year is all we know

OMG that i7 laptop is huge!!!!!!!!!!!!!

 

Nice thread guys. Will be watching and hopefully getting in on it soon.

 

I'm also in Europe. Just use ebay it's a LOT more cheaper and most vendors ship international. And I've found this: http://cgi.ebay.com/Desktop-Video-C...=66:4|65:15|39:1|240:1318|301:1|293:1|294:200
