AMD: No Grease For You!

bahamat writes "In a surprising turn of events, this article over at Xtreme Tek explains that the official stance from AMD is that you will void your warranty if you use any thermal grease or if you're not using the heatsink provided with your CPU. Sucks to be you if you buy a defective AMD CPU and put a Zalman on it for the first boot." AMD, the article says, doesn't want you to use anything "other than Shin Estu G 749."

    So what does that say? Either too many people are either applying the grease too thickly, or people are using heatsinks and OCin' their processors too much.

    Basicly what it sounds like is, people are cooking their CPU's from either/or...and AMD is tired of floating the loss because of idiots.

    Actually, they could very easily know. All they have to do is put some kind of alcohol-soluble, UV ink mark on the chip. It doesn't even have to be visible in UV... that's just if they want to be sneaky about it.

    uh, because with their thermal crap and the defauult fan, my proc ran over 130F. With artic silver and an aeroflow fan from vantec, my proc runs at 105F (115F under heavy load). Seems to me they are just trying to save a few bucks, afterall, the german economy has taken a hit lately. That is the problem here

    I don't see a problem with this. AMD will only guarantee its equipment with parts they provide. Use your own parts, and you're responsible for damage. Sounds perfectly reasonable to me.

  5. Grease? Feh. TIM pads, baby! by willith · · Score: 4, Interesting

    I've installed my last three heatsinks, including my current Zalman CNPS6000AlCu, with pink TIM wax pads. TIM pads are cheap, neat, and don't require you to get crap all over your hands during application. I'll never go back to the goop game.

    Since it doesn't make a difference what the hell you use to stick your heatsink onto your CPU--hell, toothpaste works just as well as AS-3--I'll stick with the easy stuff.

  6. Optimized Code by RWarrior(fobw) · · Score: 5, Interesting
    It's well known in some circles that using processor-specific optimized code causes the processor to heat up.

    I have two AMD Athlon MP 2000+'s in on a Tyan Tiger MPX motherboard, and a gig of ram, in a full-tower case with four intake fans -- one on the bottom front, one on the side middle over the cards, and two in the middle back under the power supply. The exhaust fan is the PS, of course.

    When running Windows 2000 on this machine, the operating temp as reported by the BIOS runs between 50c and 60c.

    When I run Gentoo Linux, set up from a stage1 install and compiled specifically for the Athlon MP, the machine crashes as the temperature rises to 75c.

    I'm using the retail processors that came with the fan. It's plain that they're installed correctly, but the thermal pad on the bottom (even with the adhesive backing removed properly) isn't capable of dissapating the heat.

    Does this mean I'm prohibited by warranty terms from running optimized code? AMD really needs to answer this question. If they want to they could easily come up with a recommended list of approved grease, or contract with someone to sell "official grease" for situations like mine.

  7. NO grease for you; you MUST use grease!! by Rufus211 · · Score: 4, Interesting
    Kinda interesting how these kinds of decisions are based on nothing technical. The basic reason everyone's been able to figure out for no grease on XPs is that:
    1) using grease means you are DIY with 3rd party stuff, which means it's easier for you (or the 3rd party suff you have) to screw up and
    2) using grease *improves* thermal contact, making it easier to overclock, which of course voids your warranty anyway.

    Now compare the XP's "no grease" tag like to this from the AMD Athlon(TM) 64 Processor Thermal Design Guide (from page 22, secion 2.6.6):
    The heat sink makes contact with the top surface of the processor package utilizing the thermal interface material between the processor lid and the heat sink. AMD recommends using a high-performance grease such as those listed in Table 6. AMD does not recommend using phase-change materials between the heat sink and the processor. Phase-change materials develop high adhesion forces between the heat sink and processor when the material is in the solid phase. This strong adhesive force may cause the processor to stick to the heat sink. During heat sink removal, this strong adhesive force may cause the processor to be removed from the socket while it is locked, and this action can result in damage to the socket or to the processor pins.
    For those that don't know, the gum-paste stuff that comes on all XP heatsinks is "phase-change material." Seems the 64 is the *exact* opposite of the XP.

  9. It's all about overclocking. by kidlinux · · Score: 3, Interesting

    This is a very inexpensive, easy to implement overclocking deterrent.

    Think about it. If it's a poor heat sink and fan that AMD requires you to use, then overclocking is out of the question because there's no way the HSF could regulate the temperature.

    See, overclocking voids the warantee, but there's no way for AMD to tell if you were overclocking. This way they do know (or it's easier for them to tell) - assuming you used a different HSF while overclocking. I wonder what they'll do when hot cpus start failing in poorly ventilated cases, or in hot climates.

    Personally I don't like it, because a crappy HSF... just sucks. I don't overclock, but I still want a half decent HSF. You could probably get away with using a different fan though. Watch, soon you'll see "heat sink extensions" that you lock on to AMD's required sink, and it extends the surface area of that heatsink.

    Though given some of the crazy cooling solutions that have been posted on /., I can understand why they'd do this. There's no way for them to tell if you weren't using a HSF on their approved list.

  10. My story with AMD heatsinks by Lord_Slepnir · · Score: 3, Interesting
    So i got my brand new athlon XP 2200. I plug it in, put the fan thingie on, and it runs perfectly. Then I noticed the CPU was running at about 70 degrees. A week later, I heard a loud clunk and my computer went dead. It seems that the fans they make are so craptastically made that one of the blades bent enough to get itself jammed.

    Why exactly would I be voiding my warrenty by switching to something better?

    And when they say you cleaned off your artic silver you tell them you used the alcohol to clean of the approved grease so the chip was nice and clean for them.

  12. State law and product warranties by Phronesis · · Score: 5, Interesting
    Why the hell do they think that they have any business messing with product warranties?

    What you want to do is go to a law library and look up Vandermark v. Ford Motor Co. 61 Cal.2d 256 (1963).

    Vandermark bought a new Ford in Los Angeles. Six weeks later, with 1500 miles on the odometer, the brakes failed, causing the car to wreck, seriously injuring the driver and passenger.

    The Ford Dealership acknowledged that the crash was caused by defective brakes, but pointed to the warranty that read, "Dealer's obligation under this warranty is limited to replacement ... of such parts ... acknowledged by Dealer to be defective." In other words, neither the dealer nor Ford would assume responsibility for the damage to the car or the injuries to its occupants caused by the defective brakes.

    One could argue that if Vandermark wanted a car with a warranty that would cover defective manufacture more comprehensibvely, he should have bought a car from a dealer that offered a better warranty, but no dealers offered warranties with significantly greater coverage. In 1964, the court ruled that the Ford dealership was strictly liable for product defects irrespective of what the warranty might say because

    Retailers like manufacturers are engaged in the business of distributing goods to the public. They are an integral part of the overall producing and marketing enterprise that should bear the cost of injuries resulting from defective products.
    . This followed the train of thought set in motion by Benjamin Cardozo, who wrote in 1916 in MacPherson v. Buick Motor Co. 138 NYS 224 (1912):
    If the nature of a thing is such that it is reasonably certain to place life and limb in peril when negligently made, it is a thing of danger. . . . If to the element of danger, there is added knowledge that the thing will be used by persons other than the purchaser, and used without new tests, then irrespective of contract, the manufacturer of this thing of danger is under a duty to make it carefully.

    You may argue that it is a long way from automobiles whose manufacturing defects put consumers and bystanders in danger of life and limb to a defective cooling fan on a CPU, and you would be right. But if you complain in general that the state has no business interfering with product warranties, a century of case law disagrees with you.

    In closing, I will point to one of the most egregious cases in this regard. In 1937, the Massengill Company put on the market an antibiotic elixer for children composed of the drug sulfanilamide dissolved in diethylene glycol and flavoured with raspberry extract. Massengill never tested the product for safety. Diethylene glycol being a very nasty poison, 107, mostly children, died shortly thereafter from liver failure caused by this medicine. Massengill could not be sued under the laws at the time because, as the President of the company said,

    My chemists and I deeply regret the fatal results, but there was no error in manufacture of the product. We have been supplying legitimate professional demand, and not once could have forseen the unlooked for results. I do not feel that there was any responsibility on our part.
    The nation's response to this was to pass the 1938 Federal Food, Drug, and Cosmetic Act, which established the FDA and granted it sweeping powers to regulate the market to ensure that all food, drugs, and cosmetics were safe. Many conservative jurists, such as Richard Posner (one of Ronald Reagan's first appointments to the federal bench) promoted this expansion of tort law, noting that there is an imperfect market for information and that when information asymmetries are present, a free market does not optimally allocate resources (this observation won a Nobel prize in economics for Ackerlof, Stiglitz, and Spence). The thinking of the economics-and-law crowd was that expansion of strict liability would produce a corrective force for disclosure of information that would enhance the efficiency of markets.

    If the ACME supercharger at a minimum meets the same engineering specs as the TRD approved unit. Then Toyota may very well be legally obliged to honour their warranty regardless of their written warranty limitation.

    Consumer protection laws allow the stipulation of specifications, not brands, models or arbitary approval processes.
