I'm putting together a new system and I felt a small electric shock while installing the CPU waterblock so I feel I may have broken something. To test this I don't want to have to spend days putting together a water cooling loop just to find I've fried the mobo, or worse, the cpu. So is it possible for me to just quickly turn on the PC, see if it posts and then quickly turn it off without risking frying my cpu?

I mean the waterblock is pretty hefty, it's an ek supremecy full nickel. And I've got an intel 6700k

I would not. Even if it started, the temperature would rise to 100c instantly and shut down before you could see anything.

A motherboard will not start unless it detects that you have a cpu fan running anyway.

For testing, I would remove the motherboard from the case and temporarily attach the parts.
It is easier to fix things that way. I will keep all outside of the case even up to installing the os and applying updates.
Depending on the motherboard, it may be easier to even overclock outside of the case.

And, 14nm skylake runs cool, you need little more than a simple tower type air cooler with a 120mm fan.

You will not frye CPU if you turn on for a short period. It will heat for a short period before going OFF by it self. So you can turn it on for a short period without risking anything. Than turn it off before it turn off by it self. It would not damage it even if he turns off by it self.

dont turn it on dry if you have a pump attached even couple of seconds with a dry pump is very very bad

in theory you can probably turn it on just with the block for a few seconds since its got overheat protection

but never done it and wouldnt recommend it either

This is what it'll look like and using onboard graphics. Obviously with the CPU power cable in too

glad to hear didnt know if you knew never run a pump dry

as said in theory should be ok though never tested that theory out with an expensive cpu

your choice really

I had an aio before this and this worked fine. But like I said I felt a shock while installing the waterblock and just want to give it a quick test. I've sold my aio now so I've got nothing else to test it with without building the full loop

Yes, and that means no POST as it will not power teh CPU 😉

OP, do yourself a favor and get an air cooler for these things. You are messing with hundreds of dollars worth of parts, not to mention you own time and effort.

You buy a liquid cooler to be able to extract an extra multiplier or two out of your OC.
How much do you really need?
I do not much like all in one liquid coolers when a good air cooler like a Noctua or phanteks can do the job just as well.
A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
in a well ventilated case.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
And... I have read too many tales of woe when a liquid cooler leaks.
google "H100 leak"

Your pc will be quieter, more reliable, and will be cooled equally well with a decent air cooler.

best idea really you can always

1 keep it as a back up

2 take it back saying it wasnt suitable

for what it will cost keeping it as a back up is a good idea though
