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?

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.

Paul,

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 DV9000 with the serialization of CNF6490HZ8

As agreed your system is billed at $125.00 for the reflow plus the cost of the screen.

Now, with the HP DV9000 with the serialization of CNF6490HZ8 has been reflowed and is ready for return. The motherboard is listed as HP Spare 447983-001. The system reflowed on both the Nvidia GeForce GO8600 (NF-G08600-N-A2), Intel SLA5D, and the Intel SLA5Q chipsets.

Your system was shipped without a power adapter.

Your system also required a LCD and inverter replacement as part of the repair service. These two units were purchased and replaced.

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

If you need more help in explaining these areas to your end user, please visit http://www.doubleclickittofixit.com/helpful-tips/

Pictures of the repair can be viewed at http://www.doubleclickittofixit.com/img

Your repair was also documented here with a video explaining much of the repair process:

Are reflow services all you perform and will a reflow fix a blinking jack on a… Compaq CQ50?

Are reflow services all you perform and will a reflow fix a blinking jack on a… Compaq CQ50?

I get asked this question fairly often, and the answer is no. We do not simply repair systems like the Compaq CQ50 that are affected by the Nvidia chipset issue; as a side note, the issue is not just related to Nvidia chipsets since it also affects Intel GPU based systems along with ATI GPU based systems also.

As an example we received a local drop off service for a Compaq CQ50-139WM laptop system that displayed a flashing DC jack and no power to the system.

The DC power jack blinked in a uniform fashion to indicate an error code, but error codes are not detailed by HP or Compaq for blinking DC power jacks, to our knowledge for the Compaq CQ50 or any system. The Compaq CQ50 was delivered due to the belief it required a reflow service for the chipsets since the laptop is a common system to be affected here recently with a chipset failure, but upon further inspection this system is an Intel based laptop (506519-001) with an Intel based processor (SLB6M) and Intel based GPU chipsets (SLB8Q and SLB95) which are rarely affected by reflow issues.

Usually we test the memory to verify that the memory is not dropping the voltage since the DDR2 slots are reversed in the Compaq CQ50 line of laptops, but a blinking DC power jack does not indicate a short, no power, but indicates a reset from a power rail failure, a blinking DC power jack.

Currently, we have a system with an Intel motherboard from a Compaq CQ50 laptop, a blinking or pulsing DC power jack, and memory that is not found to be failed.

Our only option is disassembly of the laptop to verify the issue from the circuit level diagnostics using our Fluke based testing equipment. We use a simple Fluke 117 RMS digital multimeter to test most motherboards in our shop. The multimeter can give you the best diagnostics for the laptop from our tests.

Compaq CQ50

One hour later, our Compaq CQ50 laptop is disassembled and is lying ready for the troubleshooting we perform. For our testing, we only use HP branded OEM power supplies. The difficulty with using a non-branded power supply from China or a Targus adapter from Walmart is that the power supplies are variable rate and variable wattage which could lead to issues with diagnostics. A variable rate power supply may not supply the correct or higher level of Amps while still supplying the correct wattage which could lead to a false positive while diagnosing your system on the bench.

Compaq CQ50

Before we even test the laptop again with power we test the power rail which is located by the DC power jack. We test the mosFET labeled U1 with a signifier of 4407 on the chip which is a known mosFET to fail in both HP DV6000 and HP DV9000 Intel based and AMD based laptop systems regularly. The chip reads 0.000 which shows our test equipment is working properly to begin. The way we test this chip is across the VCC and the Ground legs to measure the reading.

Compaq CQ50

Now we plug the DC power jack in to signify that the power supply is good and blinking. We achieve this test outright by plugging the adapter in.

Compaq CQ50

Then we move to testing the laptop system with the power adapter plugged in to the DC power jack with our Fluke 117 multimeter. The multimeter gives different readings from the same position telling us the mosFET may be damaged internally. The mosFET is a P-channel mosFET. The gates within the chip are switching on and off giving us the variable up and down ratings.

Compaq CQ50

To be absolutely sure, we have to do a thermoelectric test by using our infrared thermometer. By using our thermometer we can get a reading of the chip and if anything internally is failing within the chip. The chip specifics state the chip to be in tolerances requires a 25C rating or a 77F rating. With this we test our infrared thermometer to check the office and get a rating of 76F for our room temperature in our office.

Compaq CQ50

Then the chip after being plugged in to get a reading from the multimeter showed a rating of 86.5F

Compaq CQ50

After attaching the power adapter to the DC power jack and gathering a rating we had a reading well outside the range for failure specifying this chip is the issue with the laptop.

Compaq CQ50

Below is a video of our test displaying our findings with narration and explanation for those wanting to test or get a better understanding of the steps we took to test the unit.

Can your local laptop or computer shop fix that?

As a computer repair shop we see a number of damaged computer-related electronics pass through our door daily, but we also see a number of strictly electronic items from time to time. For example we had a gentleman in our local town bring us a solar panel that had a damaged crystal oscillator, if you need an explanation this will help here: http://en.wikipedia.org/wiki/Crystal_oscillator, that we tested, changed, and repaired his unit.

To the point, we are not just an average break fix computer company. We are not just a degree holding computer repair facility. We are not just a reflow and reballing facility. We are an electronics company.

We fix TVs. We fix amplifiers. We fix stereos. We fix laptops. We fix desktops. We fix TCUs. We fix printers. We fix battery chargers. We fix about anything that can be soldered or tested with a scope, multimeter, or continuity tester.

We use only Hakko-branded equipment for our fine pitch soldering. We have all Fluke-branded electrical test equipment.

Below is an example of a system that was sent to a Florida-based repair facility off of eBay who could not fix the unit. Their solution was to replace the motherboard. For all their soldering knowledge, testing equipment, and time they only could suggest a motherboard replacement.

In the picture above the mosFET, http://en.wikipedia.org/wiki/Mosfet, was damaged due to a short overloading one of the gates. This simple solder work can only be performed by hand, with the right equipment, and with the correct knowledge.

After the pick and place parts repair was performed we had a fully working and functional machine for our client in less than 24 hours.

Now can your computer shop do this for you? If not, then we are willing to offer you a deal to try our service out in the state of Georgia.

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

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.
