New build woes - one dead mobo already, same thing again

Have you removed the cooler backplate to verify it's not that which is shorting something on the back of the motherboard? Wouldn't be the first time that a Coolermaster backplate has made improper contact with components at the back of the board although am only familiar with it happening on some of their air coolers, and depending on the motherboard as well. Just something else to try.

No haven't tried that... remove the backplate and CPU? I tried running the mobo without the CPU in but couldn't get it to turn on at all. Thought mobos could fire up without a cpu attached?
 
Just the cooler backplate, leave the CPU in, if you don't have a spare stock cooler to rest on top of the CPU, then hold the pump block on the CPU (lightly) for a little contact and cooling.
 
asrock, owing to the quite frankly, stunning, customer service in the rain forest i've got a new mobo coming tomorrow so that will narrow things down a bit.
 
I am wondering why the coolermaster cooler doesn't spin on the mobo but it does on mine. So hopefully the new mobo arriving tomorrow will be ok.

This is the motherboard

Only firing up motherboard could do without working CPU (+BIOS) is going up in smoke if it has short circuit which doesn't instantly trigger PSU's protections.

Like it says on the tin Central Processing Unit is what makes computer do everything what it does.
Only own intelligence motherboard has is "wake on" functionality, which allows devices like keyboard/mouse or NIC to start power on process instead of user needing to push power button of the case.
But instantly after PSU has started and gives power good signal, it's up to CPU to initialize itself and load BIOS.
CPU and software also take control of motherboard's circuitry which keeps telling PSU to stay on.

And smoke coming from near CPU cooler's mounting backplate hints to high risk of CPU VRM having shorted.
And that's something which can "overvolt" CPU to 12V being instant head shot from anti-tank gun.
 
Would the CPU shorting stop the Coolermaster fans from spinning though. I have heard the water trickling in the pump but the fans don't spin, but the fans spin fine when testing in my own rig. And a stock normal fan works fine on the mobo.
 
I could buy a cheap Intel 1151 CPU for £50 if the mobo coming tomorrow doesn't fix the problems.
 
Many many year ago, back in 1997, I built a Pentium II where the motherboard set on fire!

What happened, the motherboard has been crushed before I purchased it, and caused some jumper pins to press together.

Now you never see it talked about or mentioned, however motherboards should be inspected before building the PC. It also makes sense to inspect around the motherboard again before switch on, making sure nothing is shorting out against a case, or you've not dropped a case screw or anything that's still lodged somewhere.
 
Just the cooler backplate, leave the CPU in, if you don't have a spare stock cooler to rest on top of the CPU, then hold the pump block on the CPU (lightly) for a little contact and cooling.

If you don't have a CPU cooler, but need to briefly power on a CPU.

If you take a small amount of kitchen towel and crunch it into a small ball about 0.5" radius, then wet it, but not enough that it's dripping. If you then place this damp kitchen towel ball on the CPU, it should give you 30 seconds just to see if the computer would post.
 
Right so the new mobo arrived today and I connected everything up with the i5 CPU. Same thing.

A cheap Intel Pentium CPU came today as well so I could test that. Plugged that in and the fan on the coolermaster cooler comes on and the computer stays on.

So it's the original CPU that took got damaged during the faulty motherboard.


Just one thing though .... according to the manual of the motherboard, a CPU pump should be connected to the header which says OPT /w PUMP (if you look at the picture of the motherboard below)

Yet if I connect it to that header I hear no water trickling.

But if I connect the pump to the header to the left CPU_FAN 1 I do hear the water trickling.

Any ideas?

Ok well I plugged the CPU pump into that header on the left as that's the header which I can hear the water trickling in the pump from.

The machine is stable, I tested the graphics card also, and that's working too.

So I guess I just need to order a new i5 9600K CPU. It's about £200. But before I do that I wonder if there's a better CPU for around the same price? What do you think? Obviously I'll ask the customer first though if there is a better CPU for not much more. But the i5 9600K is what they ordered.

Oh, thanks for the replies btw I do appreciate them, been a while since I did a computer build, my last one was my own rig which was as smooth as silk compared to this one!

Nice to see all the fans working!...

Did you have fan connected to "primary" header when testing pump in header intended for it?
Maybe motherboard needs fan connected to primary header with RPM detected to provide output in pump header.
Wouldn't be the first time for such illogical thing.

Nope, Intel doesn't have anything even remotely reasonably priced CPUs, which wouldn't be made "meh" by next-gen consoles.
Well, not that whole Intel platform isn't already "meh" compared to AM4...
Unless counting security vulnerabilities and Intel's attitude to those.
 
Sorry not quite sure what you mean.

There are just two headers on the motherboard which the CPU pump itself can be connected to (CPU_FAN 1 or OPT_FAN) headers in the motherboard picture above.

Plugging it into the header on the right yields no sounds from the pump of the water trickling, whereas plugging it into CPU_FAN 1 (on the left) does make an audible trickling sound of the water.

I was under the impression that the pump should be connected to the OPT header but the manual isn't very clear as to whether it's the CPU Pump itself or a radiator fan that should be connected to that header.

The manual says:

CPU Fan Connector:

This motherboard provides a 4-Pin CPU fan (Quite fan) connector. If you plan to use a 3 pin CPU fan, please connected to pins 1-3.

---------------------------------------

CPU/Water Pump Fan Connector

This motherboard provides a 4 pin water cooling CPU fan connector. If you plan to connect a 3 pin CPU water cooler fan please connect it to pin 1-3.


So I have the CPU pump cable connected to CPU Fan Connector header.

I'll just order another 9600K CPU then, thanks.

 
Cracking job mate and for not giving up! At least you finally got round the problem and finished the rig. I know some people would have given up long ago and chucked the lot on fleabay.

Thanks. Happy now this is finished. Just ran 3d mark timespy v1 and got 9093. Had to see what the graphics looked like these days!

Brilliant results them! What gpu have you got just out of interest? Is the processor overclocked?
