Hello, so I recently made a post asking about my brand new Skylake Intel i5 6600K CPU. If you are interested in the details here is the link : http://www.tomshardware.co.uk/answers/id-3182547/bent-skylake-build-nightmare.html

The Motherboard: Gigabyte GA-Z170X-Gaming 3
The CPU: Intel Core i5 6600K

So anyway, long story short, the PCB of the CPU got warped pretty bad, and I did try to boot the PC several times, fans started but then nothing happened of course because the CPU was bent.

So how likely is it that the motherboard took damage from it? I just wasted 245€ on this CPU and I would not like to buy another one only to find out the whole MB is toast too...

When I did try to boot it before, when I had the build mostly complete, as I said the MB seems to had been working, it lighted up the LED's and the gpu fans, the cpu fan and the case fans all started spinning but the PC kept rebooting due to the CPU.

Also as I stated in my previous post, I am confident I installed the CPU correctly, like there is almost no way I could have installed it incorrectly because I was extremely cautious and the triangle was 100% towards the corresponding triangle on the motherboard. Also I don't see any damaged pins on the socket and there are no burn marks, thank god.

So any insight would be much appreciated. Also do I risk damaging it more if I try to bend back the CPU and boot it again, trying if the CPU is actually 100% dead or not?

Thanks in advance.

I have just looked at the prior Op you made ZykciR.

Looking at the edges of the circuit of the cpu it`s self in your picture post I can see how bent it is.
If there are no physical cracks on the green part of the overhanging circuit board.

And no splitting between the layers of the green part of the circuit board of the cpu that is showing.

It can be brought back into line or levelled, straightened.

It can be done by use of a heat gun with temperature control settings set to about 190 c.

Heating the outer edge of the cpu chip where it is bent and not flat or level, moving the heat gun in a circular direction and holding it about four inches away from the chip while constantly moving the heat gun back and forwards across where the...

Thanks for the reply, although as I mentioned I have already tried to get a CPU replacement without luck.

And I don't really feel happy knowing I have wasted 245€, I would like to at least try and fix it but if I will risk my whole MB then I don't know if it's worth it...

Thanks once again, I have seen that link aswell, this is almost exactly what I was planning on trying my luck on, but like I said if my mobo risks taking damage I'm not sure whether or not to actually try fixing the CPU.

Heating the outer edge of the cpu chip where it is bent and not flat or level, moving the heat gun in a circular direction and holding it about four inches away from the chip while constantly moving the heat gun back and forwards across where the chip is uneven or bent.

You will need to flip the chip over as quick as you can so the contacts on the underside are flat down to a flat surface.
Then a moderate weight needs to sit on the edge of the green wafer circuit coloured board.
and the cpu left to cool slowly.

You may have to repeat the process three or four times.
Heating the edge that is bent of the cpu green circuit board for about five to ten minuets at a time.
The fibre board of the cpu in green colour should then level out.

And become flat and even.

If it was me I would do it if the cpu will not be accepted back as a return in it`s current state.
The edge needs to have a weight on it when slowly cooling to pull it back level under contraction of the fibre board as it cools.

It does work, but you have to keep a cool head, and take your time.

As to how it happened I think it was when you attached the cpu air cooler on top of the cpu it`s self Btw.

That there may of been a cut out on the underside of the cpu cooler where there was a step carved out on the base of the cooler.

Bit it was that and it being orientated wrong over the cpu st in the cpu socket of the motherboard and tension of the four screws crushed one edge of the green cpu circuit board.

Is there a step milled out on the underside of the cooler where it contacts the cpu have a look.
