HP Pavilion DV9000 series Laptop Heatsink Mod..

NAV33N · Sep 13, 2010

recently i was using my laptop on my lap (which usually i don't as it's a 17").
after using it for a while say around 30 mins. it was very hot.so, i downloaded the HW Monitor to have a look on the temps. and this is what i came across with..

WTF 70C on idle :no:,i was just using Firefox & nothing else..
the temps. made me worrying so i googled to check for a solution & found that this is a common problem with the DV9000 models & high temps could blow up the GPU display resulting in no display,which can only be repaired by BGA Reflow work if GPU chip is not dead or replacement of motherboard which is very expensive.

then i came across this video

i needed copper shim which looks like this

so,i started searching for copper shims as they help a lot in reducing the temps. and i found one.
it's here.
i ordered it but i never received the shim.then it was all upto me so i decided to make my own.
so,i will keep you guyz updated on this mod.

I have some thin copper sheet with me.

Here are pics:

(It isn't as thick as you expect it to be.)

Let me know, if you need some of it.

^ Thanks but it's really very thin..

UPDATE 19/09/2010

i visited a local hardware store and came up with this copper plate...

it's 2mm thick sheet of copper & weighs around 750gms,i paid 170 bucks for it...

then i marked it all up old school style using Pencil & Scale...

this is how it looked like when i marked it up..

the markings are done using scale,the surface of each square is 23mmx23mm..

then the plate is off for cutting..

that's it for now..

nice project.
i have the same series laptop with a micro wave oven inside - nvidia m8600gs

it went dead once already, m/b was replaced then.
i went for better cooling solution - home made laptop cooling pad, first few layouts didnt work well, they just accelerated dust accumulation in laptop vents.

now, i just put it on stand like cooling pad & use.

UPDATE - 30/10/10

Sorry guyz as i forgot to complete the worklog but the mod has already been completed about a month ago.

so,here it goes.

got the copper plate cut into small pieces that i marked onto it.

the end result looks like this

then it was time to get my hands dirty

i used 600 & 1500 GRIT Paper.

first i levelled any uneven surface using 2 x 600 Grit Paper (Dry).

after that i used 600 Grit Paper (Wet).

this is what i got after a hard work of about 2 hours.

after this i used 1500 Grit Paper to get a mirror finish.

after 1 hour of sanding this is what i got.

looks awesome isn't it

then i took apart my laptop & placed it on the GPU with MX-2 applied on both sides.

Now the moment of truth, has it worked.

BINGO!! it works awesome. not only now i can use it on my lap but even after hours of strain this thing doesn't goes above 62 C.

Excellent Work....Very Impressive.

awesome stuff bro

when my laptop oven goes out of warranty, i'll contact you to do this mod for me too

doing this work is fine for me, but taking the laptop apart:blushing: is hard part

^ it isn't that hard,all you need is a screw driver,steady hands & loads of time.

Do everything calmly & it ain't that hard.

I have dv5 1015tx with 9600gt installed...i have over cloacked it, my temps goes to 90 max under full load( games)...I have applied cooler master thermal fusion 400,it brought my temps down to 85 degrees max..but still its too hot ...
I think your copper chip is of no use..the work u got was becouse of mx-2 paste.
Becoz... the copper chip u placed was between the gpu and the heat sink( already of copper).....u just added extra copper to it, so the heat has to travel through yr extra chip,which will take more time to dessipate out..becouse finally it has to go through heat sink...

^ Well, i don't think you saw the video that is in my first post.

neither do you have any experience with DV9000 series notebook,since you have a DV5.

in DV9000 there is a thermal pad (non metal) between the heatsink & the GPU core,that's why it gets overheated.

by using this copper shim it provides a direct heat transfer from the GPU core to the heatsink,thus the low temps.

have a look here.

IMHO i don't see any better mod than this,if you come across one that is better then let me know.
