[SOLVED] i might have short circuited my CPU

[skyflitzer4776]

well first off, im just a very lazy person and not completly dumb, so i bought thermal paste because i didnt change it after 4 years, tried to clean the old thermal paste off but there was some on the backside (no clue how my CPU was even working) back then i knew nothing about installing pcs and i did anyways.. so i had no alcohol left and my first reaction to that was to clean the CPU pins off with water, i checked twice if it was clean enough.. put it in, tried to turn it on and... nothing at first. Well the coolers were rotating but nothing more. Disassembled everything again and did whole process all over again.. with water. after that i tried turning it on and.. bang. all i know is that my Power supply is fried now but i have no idea if it was because of my stupidity or an odd coincidence cause i had my power supply for abt 7 years now.

its an Intel i7 8700k

looks fine to me.. nothing a little cleaning up couldnt fix

oh and my power supply was a 600W be quiet bronze

Maybe there was some water on the motherboard.

A shorted CPU won't blow the PSU.

im sure there wasnt, i didnt pour water over it, i put it on some tissue and softly removed the thermal paste

You are only looking at the outside. Not the inside. Apart from the fact the IHS is generally not water-tight, there's also multiple layers to that green pcb. All it takes is a little water to get soaked up like a sponge between two of those layers, or a partial drop of water to make its way inside the IHS and 'poof', no more cpu.

Many psus are fused or have components that act as a fuse in the event of a catastrophic short circuit.

is there any way to check if its shorted without having to blow another PSU?
because ive seen some videos but most of them only show Laptop CPUs wich are mounted to the Motherboard

Using water to clean computer components has nothing wrong, I do it quite often, but the general rule is that you must wait until they are completely dried (either by exposing to sunlight for a day or using a fan overnight).

yeah, funny thing is i called with a friend while doing it and he even told me "wait a bit until you put it in again" but im somewhat unpatient, i just wanna know how to check if its completly dead

CPU or PSU?

the CPU, i figured after the Bang that my PSU is hopeless

Check cpu socket.
Might be some bent/broken/ or even burnt off pins there.

Can you show also a photo of info label printed on PSU ?

And make better photos. Your current ones are too blurry and low resolution.

my phone camera is broken somewhat but i can show a photo of the pins, they should all be completly fine, i dont see any burnt or bent pins

Water and electrical parts are a very bad mix.
I have never and will never use water to clean PC parts.

Once the CPU is dried you can tets it on any compatible motherboard, just use a hairdryer to blow hot air on the top of the CPU for a couple of minutes to make sure that there is no water left inside (keep good distance to not overheat the CPU core).

BTW, does the PSU start if you use the paperclip method?

no the PSU is completly burned, ill try the hairdrier method tho and keep it updated once i have a new PSU

so, i bought a new PSU and cleaned off my CPU real fine, turns out the CPU wasnt the one making problems.. it was just an odd coincidence that my PSU broke at the exact moment i did all that stuff, a CPU isnt strong enough to cause a PSU to blow.. so just replaced my PSU and everything works like it should, gonna mark this one as solved now
