Dead CPU Liquid Cooler?

[Joehockey90]

Not sure what's going on atm but, sitting at idle my Ryzen 1700x is parked between 75 and 80 degrees c on a liquid cooler (starts creeping up after 5 or so minutes without any more than 3% load). Worked great last night without an issue. Fast forward to just now and halfway through a Youtube video and without any notifications, the pc shut itself down. Thought, "wtf" gave it a quick once over making sure nothing was out of place, let it sit for a minute, and started it back up. Went fine on start-up (no codes/erros quick post), until checking cpu temps and seeing 93c at idle. Shut it down, replaced thermal paste, dusted radiator, and tried again. Back to the upper temps that i mentioned before.

 

Is my liquid cooler dead, dying, magically out of fluid, etc? I don't have an air cooler so I can't confirm that it is a cooler or cpu issue though the sudden change tells me maybe the pump died. The fans powerup no problems as they are designed to be powered through the pump so the mobo plug has power as well. Does anyone know how to confirm that the pump has died?

 

Specs:

-Ryzen 7 1700x no current OC

-X370 Taichi mobo

-Celsius S36 liquid cooler (had for nearly 1yr)

-Windows 10 64bit

-Zero windows errors, or notifications for monitoring software

probably would have to take apart everything and listen to the pump and see if it activates.

You should be able to tell if the pump is working or not, by the vibration and slight "hum" it makes.(a stethoscope might come in handy here... but I doubt you have that, I sure don't, not sure why I'm even mentioning this, don't mind me, I'm gonna leave now...)

Did you plug the pump itself onto the motherboard or directly into the powersupply?
 

If in the motherboard, it is possible that the computer is trying to slow down the pump(shutting it down due to lack of power), the same way it would with a fan, as such you should be plugging it directly into the powersupply.

If it is plugged into the powersupply, make doubly sure that the connector is properly plugged in and not loose, and if it's a modular PSU, be sure the cable it's linked to is secured in.

If you don't feel any vibration on the pump when it's on, that may mean you have a dead pump.

Are the tubes cool or warm? If cool, then you definitely have a dead pump.

 

A miscellaneous thing that you could try would be to put your PC on its side (Motherboard flat on the ground). If you had an air bubble(highly dependent on your current configuration), this could move it to the radiator. I'd say the chance of this being the problem is less than 1%.

 

Here's another thread about S36 failures. It goes into a bit of depth with FD's return system.

Not sure how I would do that or where I would start. Any links to a breakdown vid that you recommend or just google and wing it?

Not sure that I felt any vibration or heard any hum when it was on earlier. Pump is plugged into the CPU fan header on the mobo as it an AIO. Not sure how I would go about plugging directly into the power supply. PS is 800w supernova G2 iirc.

Not sure that I felt any vibration or hearn any hum when it was on earlier. I had the case on its side when reapplying thermal paste and problem continued.

I believe the AIO should've come with an adapter for it? Something like a Molex to 4pin cable. Some power supplies also come with them.

 

In any case, if you really don't have this, you should be going in the bios and disabling any sort of fan control for that header.

Went through the BIOS and disabled fan control for that header. Still no change but I made sure to fell the pump and did not recognize any discernible vibration or hum from the pump either.

Then it is likely that the pump is dead and you should initiate a warranty replacement with Fractal or at least contact their support to find out if maybe you're doing "something wrong".

If possible, try taking it off the CPU and trying again that way you'll be able to actually hold the pump and truly feel if it works or not.

If you start the PC without a heatsink/pump, it won't kill it instantly, you'll have a good couple minutes and it will just shut itself down if it reach temperatures too high, but it's plenty of time to feel if the pump is working or not.

Try changing the header it's plugged into as well, who knows, maybe it's just the header itself that's burnt out.

Personally I'd say to also try with a molex to 4pin adapter, but from the way you've worded it before, I'm assuming you simply don't have one of those on hands. 

 

But in the end, it doesn't seems like you're the only one with issues with this AIO
