GPU cooling? What do you do to keep the GPU cool?

I have been asked this question in the past few days quite a few times. I read what was posted by Precision Division on their eBay ads stating the BIOS files do not fix the issue, and how they modify the fan.

You have to be aware of what causes your system to fail, and what needs to be done to fix it. You have to do four main things such as update the BIOS and video drivers, exit the heat, reapply thermal paste, and change the handling.

As a repair outlet I can only do so much during the repair. Thermal compound helps greatly. Updating the BIOS and video drivers do much more for a system than hardware mods can alone. Handling has to be changed though.

I can modify the fan easily enough by clipping one wire. I suggest purchasing a laptop cooler because when it breaks and the fans die on that system it is easier to change than the weaker CPU fan that is internally in the system. As many already know, the heatsink on a DV6000, DV9000, F500, and F700 are L-shaped. Heat travels through the L-shaped heatsink to exit the system. With a weak fan exiting heat, the heat spreads through the system making the fan work harder to exit the heat. This heat remelts solder, heats your components, wears the bearings in your fan, and weakens your battery cells. Laptop cooling mats do more to move heat than the CPU fan can do on its own.

Thermal compound is key to thermal recovery. The compound absorbs the heat and causes the transfer to happen quicker. In conjunction with a chill mat, this is key to moving heat so it does not spread through the system.

BIOS and video drivers are important because they both handle how the video and system work to displace heat. The Nvidia drivers add support for games and DirectX applications, but also do more important things like bug fixes. Bug fixes can be simple problems as what the new drivers do as of 2009 which is cause the GPU to run at 10 to 20 percent power when idle. I cannot do that to as system, and neither can any other repair outlet unless they install the drivers. The BIOS update runs the fan at 5v for the complete time the system is on, but it also does another important duty: It runs the CPU at a lower GHz when it is idle the same as the video driver. This cannot be changed in the BIOS without a BIOS update.

Finally, handling is probably the single most important task. As a user you have to know your system, know the reason for the failure, and change your handling. I get calls to ask about reballing and re-stenciling with leaded solder. That will not help with anything. Heat causes solder to weaken and crack so you have to handle that issue. So handling as a user is key to continued working of a new or repaired system. As a user you have to take simple no nonsense precautions to extend the life.

Here are just a few:

Do not let your system sit on a cloth surface.

Do not block the vents.

Do not hibernate or Stand-By your system.

Turn your system off when you are not using it.

Copper shim question – Do you add copper shims or pennies?

December 17, 2011 by DoubleClickItToFixIt.com

This section will try to answer the most often asked questions I get.

Copper shim question – Do you add copper shims or pennies?

Your issue with the onboard BGA chipset is heat related. HP DV2000, DV6000, DV9000, TX1000, Dell D620, D630, D630, D820, D830 systems with Nvidia chipsets have the known BGA issues that I can fix by reflowing them.

Now, the question above is asked to me constantly. I personally do not use copper shims.

Copper shims and pennies before 1981 do not fix your issue, but do more to hamper it.

You will have three things that can happen. These are an electrical arc, an overload, or a soldering issue.

Your chipsets on your laptop 9 out of 10 times are fine if that have not been worked with in anyway and can be reflowed properly. The chipsets have capacitors located on the top and these capacitors are actually made of ferrite. When you apply Artic Silver and the copper shim in direct contact with your chipset you have stress fractures or arcing. Heat will cause the chipset to move up and down, by design, and will cause the copper to flex causing the capacitor to complete a circuit arcing between the chipset, the shim, and the heatsink which has copper in it. Placing a plastic spacer does not help any since the heat will melt, deform, or damage the chipset in its own right.

Now your chipset may get an overload and burn it out internally with no outer signs. Usually on a DV6000 system you will see a three capacitor cluster on the motherboard overload, and burn the planing of the motherboard. Overloading will cause the chipset to pull more power in the board causing stress on other chipsets such as the MAX8774, Max8724E, and MAX8734A.

The simplest issue is that your chipset will heat and the shim causes the solder to glob or puddle on the underside of the chipset. There is a reason the CPU is 5mm and the GPU is 3mm with no need to place a copper shim in to damage that design no matter how poor it may be now or before.

Joost,

This email will serve as an update on the status and repair of your systems sent in.

Currently I have listed the following machines sent in for repair by you:

HP TX1127EA with the serialization of CNF7191YFZ

Now, with the HP TX1127EA with the serialization of CNF7191YFZ has been evaluated and is ready for further authorization. The system is labeled HP Spare 441097-001. The system required a reflow on the Nvidia GeForce GO6150 (NF-G6150-N-A2) and Nvidia NF-430-N-A3 chipsets.

This service did not fix your current system due to the copper shim being in place. The shim damaged the chipset which will need replaced.

A power adapter was found within the box.

Your system displayed a typical penny fix copper shimming repair. In your specific case this was performed with a one euro cent piece. The previous repair was performed with a copper shim. This copper shim was disposed of by us. Please read our link here for a better explanation of why copper shims are not used by our repair facility: http://applelogicboardrepairservice.com/update-this-is-why-you-do-not-use-copper-shims/

You also need to update the video drivers from Nvidia.com and the BIOS from HP if one is to be applied once the system is repaired.. Please advise your end user to purchase a cooling pad to help insure the removal of heat from the system.

If copper shims do not work, then if I do a fan modification will that help keep my GPU cooler?

November 3, 2010 by DoubleClickItToFixIt.com

I get this question along with “Do you do fan modifications?” and “How do you do fan modifications?”

Here is a little tip, this concept is not a new one since I have written about how other online sellers including Precision Division out of Florida otherwise known as ibuiltonline perform his modification some 8 months ago when I first registered my website and placed the website online. You can see a video of them checking a system for the voltage on the board, but guess what voltage does not equal heat. Second the concept does more damage to your system than any good. Copper shims are the rave since it does so much for your system, but users fail to realize the risk that the modification does long term. The same is true with the fan modification.

First lets describe how the fan modification works and how it is performed. No need in getting excited, but yes I am selling you a trade secret for nada. Your fan comes with four wires. As I look at one I see a yellow, black, white, and red wire that plugs in by a Molex connector to the motherboard. If you diagram the wire schematic, you will see that the white and red wire both provide a voltage line out from the motherboard to the fan. By trimming the white wire, you have placed a direct untapped 12v line to the fan causing it to run a full RPMs. So the trick here is to run your fan at full speed, expel heat, and have a running system for how long, perhaps 120 days?

In my opinion, I see from a engineering stand point that this may be genius, but the catch. The fans are poor HEAT displacing devices in the first place. The fans are created, modeled, and recycled from Pentium M systems. The fans do not have the heat displacing capability in any capacity for a Dual Core system. What you see is not a modern marvel of engineering inside your system, but a modern marvel of accounting. Someone somewhere said that a redesign of an existing fan was cheaper than building a new one.

Then what about the modification? If you mod the fan to run a full RPMS, then how long will it last? Tell me, how old is your system? Maybe 2 or 3 years old. Then what you have is a used fan with stressed bearings, dried bearings, broken blades, maybe a stressed motor. I see modding the fan to run stronger and harder to be a unwise choice. This will help to push the system into a failure. When your fan fails then your chipset will overheat in perhaps two to three minutes. The pictures you have seen of heat guns doing damage, yeah the chipset can do the same to itself. Then in the end you will at least need a reflow, a fan, and a laptop cooler. In the extreme, you will need a CPU because they do pop like the GPU chipsets, a fan, a motherboard, and a laptop cooler. All because you wanted to get your system repaired, and you were handed a fan modified system.

I see a better alternative is this. Change your user habits, and use an external fan. I personally have three Dell D820s and D830s that I have reflowed. I reflow them myself, and have had to perform this task about 5 times due to wireless issues, but no video issues yet. I leave my systems running for hours at a time, but I own and run a reflow shop and computer shop so I have countless resources at my disposal. As a common user, you will not have that luxury.

I suggest the following to all my clients and everyone that calls me including my mother:

1: Turn your computer off when you are not using it. If you do not, think of all the power the system uses, all the other parts failing like the inverter and battery, and the heat buildup. When your laptop overheats and dries the thermal compound, the thermal compound starts to act as a insulator, ie. heat builder, than a transfer, ie. heat displacer.

2: Get a laptop cooler. I use Zalman coolers that are three fanned systems and my systems do not have issues. If you get a cheap cooler, then you get a cheap heat displacer.

3: Update your drivers. I see Nvidia.com places updated drivers about every 30 to 90 days on certain products. If you only check the HP.com website you will never find these drivers.

4: Ask questions. If you ask questions and get educated you can decide better. I find nothing wrong with one question or 100 questions. When you ask a business a few questions and that business has no time for you to answer them, then you cannot make an informed decision. I do not mind if you email me, call me, or even walk up to me to ask a question.

Update: THIS IS WHY YOU DO NOT USE COPPER SHIMS!!!!!!!

October 7, 2010 by DoubleClickItToFixIt.com

I have stated time and time again to my users why I do not use copper shims. This is a prime, grade A example of what can, will, and does happen with shims.

This laptop came in from an owner whom sent their laptop from Australia. This copper shim was placed on his system from a laptop repair center from the United States that he used off of eBay. I am not naming names of the offending company, but I will post the pictures.

DO NOT USE COPPER SHIMS! As the pictures display, this copper shim chipped the video chipset.
