Now thats very interesting, weak spot has developed into a bulge and poped, the material has thinned badly, so its stretched?

Do a test get some of you pipe, put it in boiling water for 5min using something like two pairs of pliers so you dont burn yourself see how badly it stretches... if you can incress its length easily then its not fit to be used in a cooling loop...

I've never seen anything like this. What tubing is that?

Well tubing is a polymer, of course it will stretch with heat...

I will make myself more clear for example if its 10cm before heating and 12cm long once its been stretched and once cooled its keeps its new size then is not of high enough quility or contains to much phthalates...

If its rubish you will be able to pull it like a stretch armstrong...

I would get better tubing, like Primochill

Again, any tubing will stretch if you heat it up, stretch it, and cool it down stretched. Tubing was never made to survive water of 100C (you said boiling water). 

 

At any rate I've figured out what happened here;

 

The CPU block started to heat up when the pump (which the OP has had problems with before) had slowed or stopped. This directly heated up the fitting and the tube that was attached to as well as the water inside. As the tubing got hotter and more flexible a kink developed as this was as a tight bend in the tubing. As the kink started to come up the pump probably carried on pumping at a slow speed. The kink added a lot of restriction to the loop and almost stopped to coolant in combination to the slow pump. This allowed the kink to carry on heating up as the pump carried on to try and pump the fluid forwards. When the tubing got hot enough the tubing just gave way to the pressure the pump was exerting on it.

Thanks for pointing that out ghost, but thats the point of the test to see how far it stretches if its over 20%... as its quite possible they have used a formula thats not sutable, the test that I was suggesting was a very over simplified version of a test that my lab does on pvc in inflatable toys, boiling water from a kettle left for 5min is a very rough guess to get to 90 ish c. Now in poor quality pvc you could see bad heat distortion at anything above 50c. If they have used a high % of colourant to achieve that nice white colour and have overdone the phthalates its more than likly a sub standard material caused the failure... also during the extrusion process it woul be very hard to spot any voids in a heavily colured material so it might of even been a "bubble" in the material leading to a very thin wall that caused failure.

should i email the shop and complain about the tube?

You may have got a bad batch of tubing.

 

I would still say my theory of the kink and overheating is correct and that would be the pumps fault.

[Kullzer]

the pump does this

[Spannerhands]

If you pump is doing that its one of 2 things...

1. The res is screwed down too tight or / and with uneven pressure

2. The pump is dead.

Its that simple...

im going to buy one of those repair kits and see if it works
