LIVE!!! Calling all XM chip, 3930K/3960X and ultrabook owners! Heat-Spring TIMs for testing!

Atm I'm a bit weary of trying because I have some really crappy TIM on the cards and since they stay under 82C I don't bother caring. The maximum I've been able to pull has been stable 3dmark benching @ 975/1350 single-card.
Trying to OC with crossfire on has been a disaster for me, so I haven't bothered much. When I'd pulled those clocks above, it was at 1.05V and the card reached 84C.

 

ok i'll send you some for those GPUs that sounds decent temps for this to "maybe" work.

Also what PSU do you have? are you bricking the PSU?

 

Nah, I modded my PSU to the m18x 330W PSU It's not even getting warm much. Never had a PSU shutdown on it even back when running prime95 + furmark on CPU 25/25/25/25 @ 100W/80A and gpu's at 1000/1400 @ 1.075V. I'd gotten a cooling sweetspot at that time and furmark was very stable. Still didn't trip the PSU.

Cards did overheat eventually though.

 

well at 80% you have 264w for use. when you do hit 100w for CPU if you can cool it enough 4GHz should be 100-120w if i recall from svl7 means that you are going to be close to hitting that wall i find. Figure a good 10-20w for fans/ram/hardrive/screen and what not.

i don't know how much juice the GPUs actually use since they really are not even close to 100w TDP so i figure they use 80 watts ish? i am no expert on this so i bet someone could give you a better figure. I have a feeling though if you try to pull 4GHz on CPU and stock voltages or a hair more like mine you are going to brick the PSU. Just keep an eye on it.

EDIT: i pull ~160w on F@H with 44w CPU and 7970m with slight OC/OV so you are going to be pushing that PSU to the max with two cards and a 100W CPU :/ I pull ~210w with battery charging at ~41wh

 

Ok I think it's time to introduce a little engineering here.

The power your chip draws is given out as heat, the conservation of energy applies here, energy in = energy out. Your chip does not create noise, do useful mechanical work (think a crane) or generate light so heat is the only option.

When you load your processor to higher levels more transistors are switching, it is this switching (time between off and on) that causes transistors to consume power, this is also why even at the same voltage you draw more power at a higher frequency as you switch more often.

Prime95 and the intel burn test get more transistors than normal workloads use to activate at once, which is why they consume more power.

A 65W will know its own power/frequency and loading curves so under prime where the number of switching transistors is high it can only do that at a lower frequency to ensure it does not go above it's TDP or power limit since that is fixed along with the load.

A very rough way (missing out lots of terms) of thinking it would be:

Power = frequency x load

If you fix any two of these then you have to alter the third to get a change. So if frequency and load goes up then power will have to go up to.

 

so what size are the GPU dies for the 780ms? i dont have that info from the past. Also can you send or find a picture of the cooling system? I googled around for a few mins and didn't find a good picture. Is there only one fan?

 

The 780M uses the GK104 like the GTX770 on the desktop, 294mm^2.

The 780M will use the cooling system from the notebook it is in which will be a single fan solution, eg:



There is a GPU under each fan on the left (right two fans for CPU)

And:



The two cooling fans in shown through the bottom cases there each handle a 780M.

 

thats not an m17x R2...........


second i need l*w not area...area is a useless number for cutting pieces.

I only see 1 fan...i don't see the two others NBC talks about. I want to see the pipes and how it is designed so i can understand how it cools and see if there is any reason why HS wouldn't work.

am i seeing that right? You have to remove keyboard to get to heatsinks to unscrew and apply paste???

 

Well looking at a die shot (I'm not taking the card out of my notebook) you can measure the ratio of the width to height being 275:300 so i'll leave you to work out what that makes the dimensions.



FAN1: Left.
Fan2: Middle.
Fan3: Under right heatsink.

Note in this unit only one GPU is in use so the left fan is exposed, it's normally covered by the heatsink or from the reverse angle the CPU fan looks covered.

 

that looks like the R3/4 not the R1/2. Sanemaru has he first gen m17x R1/2. It has some fan in the middle of the rick and two others hidden for the GPUs.

I know i don't convey information efficiently in text but i swear you are not even trying to read what I type :/ ^-^

 

See my edited post, and if that's the way you want to be then fine, but all the info I just posted is easily obtainable yourself with a little googling.

Also your original post failed to quote the post you responded to so it looked like you were just asking about 780M cards in general.

 

i wasn't haggling you man....you took me the wrong way. :/

Where is the second GPU and heatsink? Is it on the bottom of the MB on the left fan?

Also i did some googling and couldn't find a good shot of the whole cooling sytem. What you posted is far better shot than after i have found and not even 100% complete. Most cooling systems are easier to get a picture of....this laptop's cooling system is weird and no real good photos besides what you just posted.

Also is that the QX9300 version? Am i seeing a north or south bridge (forget which is which) on that? If i recall that disappears with the Nehalem arch right?

 

Picture the heatsink on the right but inverted so the fins still sit on the edge of the case.

Yes that likely is the core 2 series mobo as the nehalem got rid of the north bridge (but still retains a south bridge which is normally passively cooled.

 

oh i see the grayish bar doing up and down next the the CPU on the left is the MXM board slot. The fan was weird looking and looked like the GPU was on the other side. Thanks i see how that works now.

 

Huh, nice system Meaker, really left me scratching my head a little there. Yea, mine looks somewhat like that (the CPU heatsink is shorter without that extended heatpipe) and I still have everything inside mine. It's a terrible pain to open everything up for a repaste or cleaning though.

 

@Hopelesslyfaithful: You got PM'd Hope those measurements help

 

does this replace the thermal paste for the cpu and can it be used on gpu?

 

Yes and yes.

 

anyone know where i could buy a single one? the website only has a bundle of it. i dont need that much, and i cant afford it.

 

Hi Pinoy.
In my thread (sig) we're making a show of hands to see how many people are interested. There's about 6 so far. We were thinking at 10 people we'd make a group buy (it would come to around 30$ + shipping for 5 pieces each).
Join us if you want.

 

Hi I'm running a QX9300 on a Sager NP8662. My system runs at 3.72ghz at 1.3625 volts with 1066 bus. My system gets pretty hot, i have IC Diamond but have repasted 4-5 times already because it seems to lose performance every 3 months. Today my temps peaked 104C but it's usually around 88C and my lowest temps are 43C. I use my computer for BIM and architectural design. I have a gtx260m installed. It's an old machine but the upgraded CPU keeps it functional even for heavy work loads, but the temps are really a problem. I'm interested to try the heat spring but i am not sure if i qualify, i live in the Philippines.

 

well now i dont care....i just typed a huge response and it didn't save or post. I really need to remember to just control a and control c everytime -_-

Anyways i am sending the stuff out monday. Forgot post office by me is closed on saturday. Everyone is getting 2 pieces except for the 920xm guy he gets a spare since i sorta botched one...you might luck out. The rest of the advise i posted was about no pressure paper...it is useless. Also don't bother sanding...needs to be machine level accurate....hand or even using special sanders is too inaccurate. Also try messing with screws while it is on. See if you can get a better temp. Also it takes a few hours or days to fully work...i forget which it is.

Also please clean the sheets with a mild cleanser they can oxidize so that should give you mildly better results.

was some other stuff but i hate how that happens grrrrr

 

Is this ancient, or still going on?

TIA,

flashtee

 

I'm interested in this too for my 3940xm which overheating...

 

I would be interested too...
