Intel Skylake CPUs are bending due to some coolers

[DKT27]

Skylake uses a thinner substrate than Intel's previous generation processors.

Intel changed the thickness of the substrate for its Skylake (6^th 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.

wondering why they change the thickness of the substrate in the first place? Where goes the famous rule: if it aren't broken, don't try to fix it? The old substrate structure has been working for decades, why change it now?

I guess it's the costs. Having said that, Skylake CPUs are little costly than many of the previous gen CPUs from Intel.

CPU's without pins.... Wanna-be GPU's..... INTEL! :thumbsdown:

Intel says that Skylake is rated to withstand 50lb ~ 22kg of static force. I wonder why a cooler need to go even near 20kg! :think:

it's not the weight of the heat sink, it's the force exerted, usually from picking up the motherboard by the hs.

 

that used to be harmless not long ago but habits stick, and bad habits more so. i've already had to...let go of a couple interns for doing just that.

You will have already problems with less weight, because contacts are only luck...

Good CPU's have always 100% reliability and there are simple physical reasons for pins!

If you pick up a Skylake in your hand you'll find it to be surprisingly bendy...

I am not talking about the weight of the cooler either. I mean, who can imagine a cooler of 20kg or 50lb in weight. That's insane! I was talking about the force exerted by the cooler on the CPU die. In that case 20kg looks too high for me.
