DV9000: Thermal pad or copper shim?

Hi! I recently bought a DV9000 from my local electronics recycler, and it, of course, has the notorious GPU issue. I have ordered a refurbished motherboard, but was wondering what the consensus is about whether a thermal pad or copper shim is the way to go to dissapate the GPU heat on the new board. I'm sure HP doesn't have an official stance on this, but I would like to hear from anyone what their choice is, and why. Thanks!

I usued to place copper shim until I found K5-PRO viscus thermal paste. Copper has great thermal conductivity but it is electrically conductive and can cause damage and also if it is slightly thiner or thicker it won't fit perfectly. K5-PRO is a very gummy thermal paste designed for thermal pad replacement. Try it and you will see that it is the perfect solution for all cases when you need to replace a thermal pad.
You can see a video about it here https://www.youtube.com/watch?v=e9v5MDivZfc
and you can find it on ebay here http://www.ebay.com/itm/261419323645
It is also avaliable on Amazon...

Hi, have 5 pavilion DV9000 laptops to service. Do I need to add copper shims to the video & NB chip?

Hi,
I know there was a problem with thermal cooling of the vieo chips on some of the models. As a precaution to keep my customers happy I would like to modify these to last. All systems will run Windows 7 Home Premium.
There is a "cult" folowing on these and I own 2 myself. All of these are getting replacement motherboards which includes the extra 256mb or 512mb Nvidia video chips.
I make copper shims at my business here in Albany, Oregon for water and air cooled systems and would very much appreciate any advise you can offer. There are many opinions on the internet but none from HP directly. Thank you very much.

Hi:
The easist thing to do is to look in your device manager and write down all of the major hardware components listed by model (graphics, audio network controllers, etc).
Then you will know what drivers you need.
If your notebook has switchable graphics, you will need both video drivers.

Dv5t-1000 thermal pads

My dv5t-1000 seems to be running hotter than normal. It's 5 years old now and I figure it would be reasonable to overhaul the cooling system. The fan doesn't seem to be blowing much air anymore, so i"m going to replace it, as well as clean out as much dust as possible (shouldn't be hard since I will need to take the laptop completely apart). I'm also going to replace the thermal compund and thermal pads. The problem is, I don't know how thick the pads need to be and I can't find this information anywhere online. I really only want to have to pull everything apart once if I can help it. Can anybody tell me how thick the new pads I buy need to be?
TLDR: How thick are the thermal pads in the dv5t-1000?

I got a set of K5-pro and K4-pro thermal pastes from ebay ( www.ebay.com/itm/261419323645 ). K5-PRO is a thermal paste for themal pad replacement. I use it in all cases instead of thermal pads and I don't have to care about thickness any more. Copper has better thermal conductivity but it is impossible to make it fit on the GPU and under the heatsink perfectly and it is electrically conductive so still K5-PRO is much better I think. K4-PRO is the best thermal paste for reasonable cost that I have used so far. You only need one small drop on the CPU.
there is a video about these products on youtube here https://www.youtube.com/watch?v=e9v5MDivZfc
K5-Pro is also avaliable on Amazon... http://www.amazon.com/gp/product/B00K04D3UK

Thermal pad under LQFP48 package

Hello,
I need a thermal pad in a footprint of a LQFP 48 package - the pad should have some vias to the bottom side.
I had no issue to implement the LQFP48 package with the part wizard - but havebn't been able to use "Pins" and "Copper area" to implement a decent thermal pad into the footprint which should be then pin "49" of the package.
How can this be done with Ultiboard.
I would like to point out, that I would like to have this pad in the _footprint_ !

Hi tbet,
Generally thermal pads are added using a the rectangular SMD pin (or custom pad shape if you require a cutout). an example using the custom pad shape already in the database is the QFN40P600X600X80-49N.
This is easiest to do after clicking the "finish" button in the part wizard, while still in footprint edit mode.
An alternative to this is to edit the footprint after being saved using the database manager (tools > database > database manager) and edit the existing footprint.
From here you can use the pin placement dialog (place > pins) to select your desired shape from the SMD Pin dropdown.
If you wish to use a custom pad shape, it needs to be created before the land pattern, which is done via the database manager.
From the database manager click the "Create New Part" button (Ctrl-N) and select "Custom pad shape", You will be brought to the custom pad shape editor where you can create the pad(usually done with a Polygon). Ensure you save the pad to the database when finished.
The pad is then placed from the pins dropdown as noted above by selecting the Custom shape and locating your saved pad in the database.
Regards,
Jason

Coins, alternative to copper shims for heatsink???

Hello, I have a question, can I use another item as a heatsink instead of the copper shim??? because in my country (Venezuela) I can't find. Something like a coin, I readed in the forum it's also recommendable, but I want to be 100% sure since it's the first time I hear about the copper shims/coins as heatsink
Also hear the silver is good, what about the nickel??? can it be used too??? Since here the coins are made made with nickel, and I don't know if it's a good metal for heatsink
Thank you
This question was solved.

I will mention here in the I used a (USA) Dime for a spacer between the graphics processor and copper heatsink to improve the thermal paste connections on a dv6000 laptop and that worked. The laptop no longer did a thermal shutdown when I get hot but it did blow alot of hot air out of the vents.

E220s freezing without symptoms after renewing fan and thermal pad

Hello fellow Lenovians,
I recently renewed a rattling fan in my E220s. Since then I get permanent freezes every time, starting from ca. 5 to 40 minutes on. I checked with Sandra, and to my understanding no temperature sensor shows anything abnormal.
Since the thermal pad on the chip to the left from the CPU (northbridge?) seemed worn, I renewed it also with a 1 mm 7W pad. After dismantling again it does seem not the whole (but no less than 80%) of the chip's surface is hard pressed to the pad. I understand it's all the screws that keep the structure tight, but I have no more ideas on how it can be wrongly fit - or improved. Please note I have dismantled the laptop including the fan assembly several times before, without any noticeable issues. Yes I do use thermal grease/spread for the CPU.
Many thanks in advance,

bump.

G62 thermal pad replacement

Hi,
I'm fixing a friends laptop with overheating issues. I've looked over the disassemble and find nothing I can't do (alot I shouldn't have to, nice design there HP).
My only question is whats the size and thickness of the thermal pad needed for the GPU? I'd hate to have to trial and error it.
Thanks

Wow... support.

Thermal pads for MSI GX640

Hello,
My brother has the MSI GX640 notebook. It's already a few years old and it's overheating easily.
I wanted to replace the thermal paste and thermal pads.
Thus, my question.
Does anybody know how thick the thermal pads in this model should be?
Cheers!

you may check with MSI directly but if you use thermal grease, a drop that could cover the core is enough.

Msi gx60 repaste + which thermal pads

Im doing a repaste of my CPU and GPU with ic diamond and now i have a question about the thermal pads. Can i use 1mm thermal pads ??
Kind regards

The only comment I would make about this, and take it as criticism to better your tutorial next time, is to use a more precise measuring tool. Small metal rulers with very precise measurements can be had for $1 at hardware stores, and they would be invaluable in most of the pictures compared to the broken school ruler.
Again, just some constructive criticism. Otherwise this is VERY informative and well written.
I take it you didn't have any issues swapping out the 680M for the 780M then?
Yes its true, sry about the broken school ruler, i was a little bit lazy to buy a better one, i think main thing is the information and not the optic here but you are completely right
I didnt changed to 780M because i found some posts in different forums where people wrote that 780M become hotter as 680M and my 680m getting 80 - 85°C in games like BF4 (without OC), by the way what are your max temps in graphic intensive games? ( I have GT70 0ne, same model like you)

Re: Replace thermal pad GT70 2 PC

Thermal pads for VRAM are 1.0mm, but other pads for electric components are 1.25mm. Don't use too hard thermal pads or they will likely leverage some part of the thermal pipe and make it untouched from some electric components then cause the components...

What's your BIOS & EC versions?
Where did you get those drivers?
Did you update the video BIOS?
Check the GT70 2PC product webpage and update all above.

12"PB 1.5ghz...Thermal Pad or Paste??????

Hello,
Can any of you fine folks tell me what exactly is used on a last gen 12" 1.5ghz Powerbook? Thermal Pad of Thermal Paste?
I am putting a few dollars into my PB (7200 rpm HD, max ram and a replacement glossy screen from Techrestore) and was wondering if it was worth using AS5 (Arctic Silver5) to keep the heat down a bit.
Thanks Bunches

As far as I'm aware G4 processors always use thermal pads specifically shaped for the chip.

Z60t processor thermal pad needs replacing

hello,
one of the paraffin thermal pads (not the grease) that attaches to the heat pipe/sink has come off. i had the fan out to clean the fan grills yesterday and noticed it was loose. i tried to reseat it, but it doesn't seem to have worked.
this is for the processor in the centre of the machine, not the cpu near the left hand side.
does anyone know what that pad is and were to get replacement? i can find thermal tape, but not anyone who sells this pad. is is sold by lenovo? this machine is 3 years old and out of warranty.
desperate,
tim

I'd imagine that what you're looking for is included in FRU 26R9544...but give Lenovo a call and double check by all means.
Good luck.

CPU fan/thermal pad

I am trying to purchase a new thermal pad, but there are so many. I am trying to pull up a picture of the fan from the HP parts store website but am un able to do so. Does anyone have a picture of the CPU fan for an HP Pavillion dv7 model # 7135us. The part # is 682100-001. Thanks Janelle

With a Duron 800 and a Thermalright SK-5 and a 60 MM fan blowing about 12 CFM i was sitting around 120 F. I installed a Valcano 9 and the temp whent up to 131 F. I thougth i installed it wrong so i took it off, cleaned it and re aplied some Arctic Alumnia and the temp was stilla round 130 F. I took it off, put the SK-5 back on and it dropped to around 124 F. I took the 80 MM fan off the Valcano 9 and placed it on the SK-5. The temp whent down to around 118 F. Needless to say the Valcano 9 heatsink is a peice of . Or my first generation old ass SK-5 is badder asser. But i dought that seeing the I was getting the same temps with a $8 CoolerMaster.
Now with my Athlon 1700+ @ 195x10 I hover around 127 - 131 F with the Thermaltake fan from the Valcano 9 at its lowest setting, compleatly silent, spinning about 2500 RPM's.
I attached the sensor from the Valcano 9 to the bottem of the Proc whith some thermal tape. With a little re-wiring i ran it into my Vantec NXP 201. What ever it reports is usally around 3 - 5 C lower then the Bios. Usually around 48 C. I thought the Bios temps where way off. But now lookign at it i'm not so sure they are. If the temp in the Bios is being taken fromthe core of the Proc and the temp on the Vantec Nesus is being taken from the bottom of the proc, and theres only a free degrees difrence, i'm not sure the Bios is wrong.
This is on an ILSR BTW..

MSI GT683 Cooling - Thermal Pads and Mod

Hi,
I have a MSi GT683 notbook. Sometime ago i upgraded the GPU (https://forum-en.msi.com/index.php?topic=168610) and because of that i started to have some problems that turned out to be caused by the power supply not being strong enough (https://forum-en.msi.com/index.php?topic=172580).
Now i bought a new power supply but i am afraid that it will get my temps too high, so i want to do a maintenance of the notebooks cooling (change thermal paste and thermal pads) and maybe mod it a little bit.
But i have some doubts that i need some help with.
First, what thermal pad thickness should i use on the GPU? I changed the GPU from a 560M to a 675M and bought the appropriate heat sink.
Second, can i cut a hole in the underside of the notebook so that the cooling fan can get more air?
This is where i am thinking of cutting the hole:
It will be a small hole, that i will cover with a mesh to keep dust out, directly above the fan.
And i am going to buy this notebook cooler (http://www.coolermaster.com/mobile/notepal-series/notepal-u-stand/) which i probably going to mod changing and adding more powerful and quieter fans.
What do you guys think?

actually cutting a hole under there is useless w.o cooling pad but if you can build up or find a good cooling pad which directly push cool air thru that hole then it makes some changes.... i have went thru lots of forums, sites and any other informative places about modding notebook cooler and found out that best cooling method is that little bit alluminum + cooling pad + remove the whole lower case will give you 50-60C when your on full load.... so i tested out whichever method i have read and heard... adding alluminum on the both thermal parts on gpu and cpu w.o removing lower case and putting cooling pad under it gave me higher temp than normal... so i remove the lower case and put it on cooling pad 10 - 15C decrease than normal but i dont use my nb as station so its not for me... then i removed alluminum blocks and put the lower case back and put on a cooling pad gave me 5-6C lower temp... then i drilled some holes where you are planning to cut holes with 0.3 and put it on cooling pad then i got 9-13C lower temp normal and i tested it w.o cooling pad then i got exactly same temp as before cutting hole on the lower case... so i think that cutting hole under fan makes less air circulate is bias understanding and for my case its proven for me... so i am advising you to cut a hole there but not a big one use 0.3 drill that will give you some manufacture like clean cuts...
also refer to this fix http://forum.notebookreview.com/sager-clevo/674825-improving-p170em-7970m-gpu-cooling-performance-foiled.html
i know msi fan is not loose as clevo but it helped me lower some 2 3C

Gtx260 twin frozr OC, i need recommendation from thermal pads to replace

so i have this graphic card Msi gtx260 twin frozr OC
Replace it by mistake by one of poor quality and damaged the original and wanted to know if I can help get the original or a recommendation or if there is any way to know what are the specifications of which was bringing factory installed,
the original thermal pad with green white very soft and thin (0.2 mm I think) on the component side was bringing a very fine fiber
initial temperature of approximately 113 122 new GTX260 farenheit
after 2 years of use 122 131
and now now 1 year after the change depues thermal pad, my mistake. The temperature is 140 to 149 farenheit
these are the specifications that use thermal pad. -
Thermal Conductivity: 6.0 (W / m.K)
Hardness: 35 (shore 00)
Density: 3.20 (g/cm3)
Dielectric Strength:> 14 (kV / mm)
Dielectric Constant: 15.0 MHz
Flammability: U.L. 94 V-0
Continuous Use Temperature: -60 ~ 200C
I live in mexico and it is difficult to achieve thermal pad.
PLEASE HELP.

Any reason you are not considering using thermal paste instead ?
