Tube Bursted

[kullzer]

hi

When i woke up today i started the computer, went down stairs to get the usb cabe from my back pack,i heard a pop and tought it was something that fell.
When i get to the room i can hear air inside the radiator, so i turned off the computer.
how did the tube burst??
here are some pics of it

does anyone know why this happened?
the tube is MasterKleer 10mm/13mm


i asked arround and foruns and stuff and everyone have a different explanation.
from what i saw i think that the pump dident started and the water boiled,but i think for the water to boile the cpu would need to be crazy hot, but my computer shuts down then the cpu hits 100ºC

the only explanation i could come up would be that the tube was weak at that spot and that there was something congesting the cpu block causing high pressure. a very weird situation.
pretty much sure it wasn't the heat, you need a lot more for that tube to melt.

DAMN!!!! Looks like a defect in the tubing manufacture and the loop pressure has just broke free at the weakest point :-( I don't think the fluid would have reached a boiling point hot enough to burst the hose. What is the hose rated at temperature wise?

i checked the block and it was clean,if the loop is closed how could the pressure get high?shouldent be the same everytime?
i mean lets say the block was congestiod, the placed that bursted was beetwen the block out and rad in,that means that the pressure was passing the block and if it got blocked it was on the rad

probably an airlock.

took it ouy of the ek web shop

Maybe it was a lack of attention when you cut the tube to right lenght and gave it a little cut in that spot which weakend it. Also from the pics the tubes from the cpu block seem a bit kinked which could have added enough stress on the weakend spot to make it burst. The tubing you are using has only a wall thinkness of 1.5mm which is thinner then 10/16, 11/16 or 13/19mm.

Who knows how this happend...?

Edit: Or maybe the ring of your fitting cut it depending on which fittings you used (brand, quality, finish, sharp edges).

I'd seriously consider removing and draining the radiator to see if its clear and not blocked.

But like everyone else has said who knows how it happened we could only really speculate the true cause. I think it's safe to say it's either Pressure, Temperature or Weak Hosing.

forgot to mention that in a couple of ocasions the pump had a problem starting

With you saying this and that the hose is rated at Max 73.9C if your Pump failed to run your CPU will have just gotten hotter and hotter, seeing as you state at the beginning of this thread your CPU shuts down at 100C you're well over the threshold for the hose. Seeing as it has blown at the block that is the most likely scenario.

I seriously doubt that it was too high pressure. I can easily clamp 13/10 mm tubing shut with
my bare fingers on a D5 pump running at full power. If the pump really was strong enough to
rupture a (weakened) tube I think I should at least feel some decent resistance when pressing
on the tubing with my fingers.

Tough I will admit, that's just guesstimation.

If the water was boiling and turned into steam it would be another story, but I think that's
even more unrealistic.

I've once had a leak because I tightened the compression nut too much and it damaged
the tubing. It cracked after a few weeks of service. So I'm with FTR.4500MHz on this one:

i used scissors to cut,
here are some pics of the tube

edit:i dident tagged the link due to the size of the images

Wow that's the first time I've ever seen anything like that. Was it kinked at all at that point? Maybe it had a weak spot there too. It seems like such bad luck and I think it'll probably be a combination of things.

I don't think boiling water sounds very logical as why would that burst the pipe in one spot? It'd just melt it surely.

The pressure typically isn't that much but looking at those pictures it looks like it really exploded out of there. The wall thickness looks pretty thin too.

Are all of your components okay by the way?

the gpu got water on it(for the second time xD,im suprised it still works)i gt a grey screen when i was shuting the computer off, i let it dry on a bag with rice for 1 day and is work normaly.
when the pop was loud i heard on the first floor of the house, the sidepanel of the case was wet from the explosion,it sounded like a champgne bottle beeing opened

That's absolutely insane, I still can't believe my eyes lol.

I got water all over my GPU and the PCIe slot when I first watercooled.
I screwed too far into the rad and when I turned on the pump it just sprayed everywhere xD I got a funny screen but it went away after fully drying out lol. It was pretty scary times

the first time it got wet i had a fan running at full speed,i went on the bios and set it to 50%,when i restarted the pc the pump dident (sounded like the pump turned on for half a second and them shuted down)
i tried to move the pump and the gpu fitting was a bit loose and the tube came off,the gpu got wet but the system was off the wall,
but this time the system was running, it ruined my day, i just wanted to sleep for 2 days straight to test the gpu after it dryed

Damn, that literally exploded on you !

Looks like a manufacturing problem judging by the thikness of the shredded parts.

Deffenatelly some material missing there.

should i also get a new pump?
with a bit of googleing i found out that some people have had the same problem with the pump.

"The problem is when the pc start the Laing pump dont start, it can be hear a short noice inside the pump like he want to start but something keep blocked"

i really dont want to expend 80€ on a new pump =(
