    Default Intel Skylake CPUs are bending due to cooler mount pressure

    Looks like #Bendgate is back.

    Intel Skylake CPUs are bending due to cooler mount pressure

    Intel changed the thickness of the substrate for its Skylake (6th generation) Core processors. However the thinner, less rigid structure could lead to many well known coolers damaging the chip and/or the motherboard, says a report by PC Games Hardware in Germany.


    The report says that due to the chip's weaker supporting structure, the pressure exerted by a number of well known coolers is simply too much and is causing components to bend. The mechanically weaker CPU, its pins, and the motherboard contacts can all be bent and sheared by the pressure exerted by cooler clamping mechanisms. Even if that doesn't happen straight away, as you system sits on its desk, the moving of the system anywhere, if it receives any knocks or bumps in transit, could result in the structural ill-effects.


    PCGamesHardware.de has discussed its findings with a number of key PC cooler makers and already received replies from most of them. The following feedback was obtained during the investigation:


    • ARCTIC: "We want to assure with this official statement that ARCTIC cooler not affected by these problems - and thus are fully Skylake compatible". The company said it adhered to Intel's mechanical specification.
    • EK Water Blocks: "While current water cooler of EKWB are fully Skylake-compatible, the manufacturer advises caution with older coolers," noted PCGamesHardware.de.
    • Noctua: "Our SecuFirm2 mounting systems are subjected to prior to the release of new platforms an extensive compatibility testing" said Noctura. No problems have been reported to Noctura by customers or re-sellers etc.
    • Scythe: This well known cooler company admitted that while "All coolers are in fact generally compatible with Skylake sockets… in some cases result in damage to CPU and motherboard when the PC is exposed to stronger shocks (eg shipping or relocation)."
    • Thermaltake: "All current CPU cooler from Thermaltake, as the Frio Silent series, as well as older models such as the NIC series, the Contac series and the Frio series, and compact water cooling of the types Water 2.0 and Water 3.0, are 100% compatible with socket 1151 processors."
    • Thermalright: "The pressure is pre-defined and accurately based on the specifications of the CPU manufacturer," said this company. There are no reports of Thermalright cooler induced problems so far.


    The feedback from various cooler makers is augmented by Tom's Hardware, which has garnered statements from NZXT and Intel but says that Cooler Master and Corsair are yet to respond.


    • NZXT: said its "Kraken Series closed loop liquid coolers are fully compliant with Intel's socket 1151 mechanical force specification". It recommended against using older larger tower coolers like the Havik 120/140 due to force and weight considerations.
    • Intel: said that it has only been made aware of the issue in the last two days and it is therefore investigating what "could be several variables at play". Intel confirmed that Skylake uses a thinner substrate but it is rated for the same 50lb. maximum static load as prior generations.



    Scythe appears to be the only major cooling company affected in reports so far. However it already has a free solution in place for customers who want to prevent the chance of processor and motherboard damage. Owners of the Ashura, Mugen 4, Mugen 4 PCGH-Edition, Fuma, Ninja 4, Grand Kama Cross 3, Mugen Max and Kotetsucan request a free replacement screw set.

    > $400 CPUs... And Intel is too cheap to brace the heat spreader with $.05 worth of aluminum


    >> its not the heatspreader that is bending, its the substrate that is affected.
    It's also not Intel's responsibility if a company doesn't adhere to Intel's specifications when designing its mounting mechanisms.

    Thus far it seems to be isolated to Scythe coolers but Intel is doing its due diligence to varify that.

    >>> It looks like the issue is one of two cases:

    1. The system is moved around heavily and dropped (such as in shipping) or

    2. The heatsink mounting causes more pressure to be put on than the CPU can handle. This is not due to there not being enough aluminum but rather than the CPU itself is smaller and thinner due to newer technologies.

    This issue probably will not affect 99% of the people.

    99% percent of people? Who are they sh***ing| it will somehow. Oh sure 14nm upgrade ain't enough they had to make with materials lacking tensile strength. ARE YOU EFFIN KIDDIN ME INTEL???!!!!!

    To think I was considering buying Skylake

    I still am considering to buy it though..
    Well, Cooler Master, Thermaltake and other mainstream coolers confirmed their stress/pressure compatibility with skylake.. and personally consulted with some users who have been using with 212x for the past months and did not suffer this issue.. .So, Let's hope for the best :/ or some youtube videos (bcz reassurance from Intel would not be enough now i guess)..

    Can anyone clarify if the Cooler master hyper Evo and TX3 models are known to cause this issues as well?....if yes then good lord i might have so many people call me for RMA's

    I know my 212X is gonna break it even in the socket since that pressure feels kind of dense
