That's odd. The Silver Arrow usually loses (narrowly) to the nh-d14. No way it beats a d15.
When I bought mine, the tests showed that under low temps, the dh-d14 would win, but at high temps, the Silver Arrow wins. The results definitely varied from test to test. There definitely isn't a lot of difference between them either way.

What I've see and found is original Silver Arrow was slightly better than NH-D14 But yeah, both are a couple of degrees warmer than D15 and PH-TC14PE .. and R1 Ultimate.

IMHO the 200-300rpm faster speed / additional airflow the NF-A15 1500 fans have is the reason for the couple degrees difference.

All CPU coolers worked fine on Haswell CPUs. On Skylake some don't, despite that the CPU coolers have not been changed. Obviously the Skylake substrate is more susceptible to bending problems than Haswell, since the CPU is the only thing that has changed.

The Skylake PCB is changed. It is thinner than other 115x PCBs' This make is easier to flex and /or break. This does not mean it is not strong enough to be stronger than specifications require, just not as over strength as older 115x PCBs'.

It's thinner, but not easier to flex, imo.

Thinness doesn't necessarily equate to strength or flexibility.

If it were easier to flex, this deformation would be common, instead of so rare as to be hard to document.

Intel's reply is that it conforms to the same spec which is not the same as saying the thinner pcb is just as rigid as the old pcb. The old pcb could have a generous margin over the 50lb spec, say 75lb while the new pcb could be barely conforming say 50.1lb.

Since the problem doesn't seem to be reproducible, its probably something wrong with that particular reviewer's mb socket, or heatsink or something. But that doesn't mean the thinner pcb is just as strong as the older thicker one.

Exactly.
What reviewer are you referring to? My understanding is the only instances were the result of shipping with cooler mounted and due to impact load.

We can tell that the pcb is actually equivalent, as Intel said, because we aren't seeing any problems with it, despite the number of 2.5-3 pound coolers out there.

Saying there are no problems is a bold faced lie.

There have been a few problems. I know this not only from what we have seen publicity as well as from other sources.

But saying it is big problem or that the 1151 is not built to spec same as other Intel CPUs is also a bold faced lie.

And while we are on it, your sig says a lot about your credibility.

That German reviewer who posted the bendy pics from the OP's link.

pcgameshardware.de, did report they damaged a Skylake.
... we have combined a no longer released for Skylake cooler holder, a heavy heatsink and extreme acceleration scenarios, ...
http://www.pcgameshardware.de/Skyla...ls/Skylake-Gefaehrdung-durch-Kuehler-1180505/
is the Google translation. I'm assuming the "extreme acceleration scenerios" are sudden changes in speed like the difference between a falling object and when it hits the floor.

They go on to say:
we put the test system in operation step by step ever higher loads from the radiator. On heavy blows on the table, which have led, according to an OEM manufacturer to a Skylake failure, cases result from a few centimeters in height, as can happen involuntarily in Handicrafts and cleanup. At the end of the test series, the PC is put into a shipping container several falls from typical carrying height and finally thrown out of two meters to the ground to simulate extreme shipping charges.
http://www.pcgameshardware.de/Skyla...ls/Skylake-Gefaehrdung-durch-Kuehler-1180505/
Google transation

They go on to say:
We subject the components of the computer while an external examination and found significant effects of the test load: The housing is severely deformed, the envelope of the power supply so severely dented that no safe operation is no longer possible. Even the heatpipes of the heatsink have a bit bent.
http://www.pcgameshardware.de/Skyla...ls/Skylake-Gefaehrdung-durch-Kuehler-1180505/
6th paragraph
Again, this is Google translation.

But I hardly consider any system that has a bent case, a bent PSU and bent heatpipes on the cooler .. and the CPU doesn't work can be honestly interpreted as a CPU failure because of it's construction.

Frankly I would be surprised if a system would ever work without lots of replacement parts after that kind of treatment. :D

What they found in the shipping box after their "test" shipping. :D



Skylake on bottom is from same system after"test" shipment



PCB on left is Skylake compared to older ll5x PCB or right


http://www.pcgameshardware.de/Skyla...ls/Skylake-Gefaehrdung-durch-Kuehler-1180505/

So, yeah, you can definitely do a lot of damage. But it is equally definite that to do that kind of damage requires extreme effort. ;)

As far as I know 14 cooler companies have made statementssaying 1151 is completely comparable .. all after Scythe (the only one to have problems) reported the problem.

Sorry bononos, but it appears you engaged mouth (fingers) without first engaging brain.

As expected it was a sensationalism article. Now they come clean in the followup.

That PSU and case is just trashed, but I am sure someone will make it sound like that's Skylakes fault too :D

Indeed. :D
I don't know if this was what started the whole thing, or a followup satire of it. But if it was what started the whole thing and Scythe based their notice on these sensationalizing idiot's or not, but if they did start the whole thing they should be jump on them with both feet .. by everyone in the industry.

Isn't this from a separate test?

Lighten up, Francis!

My sig is a nice joke from way back in the rough and tumble P4 vs AMD days...

forums.anandtech.com/showthread.php?t=1504548

If we can only find a couple of documented examples, and those examples have conditions beyond normal, then there are no problems with Skylake and LGA1151 as far as I am concerned.

It may well be just a satire. I don't know.

Anyways, it shows the 1151 has no issues as long as it is handled the same way as any system with a large cooler should be handled.

Francis isn't here. :D
He stepped out front with his 1151 system to test the mounting "issue.":whiste:

Obviously not.

This is what happens when you post something without knowing the facts.

Actually, in my review of the Ninja 4 (nice heatsink, BTW) I criticized their mount -- before the German article came out. So it's something they were already thinking about.

I'm glad they're replacing those screws. Other than the unregulated screws, it's a nice mount.

You said you didn't like them. That's not even close to saying the mount was damaging the CPU or socket.

Maybe it is possible to do, but I will still put my money on sudden impact being the cause of the damage .. That or someone setting on top of the cooler. :D

Why don't you post some facts to back up your claims for once, instead of just posting your claims?

Looks like you engaged your fingers without reading carefully yourself. I only posted the German link because you asked for it.

All of my posts did not say the thinner pcb is more susceptible to bending under normal use. Basically what you said in your post #104.
