READ! Make Sticky

Well I was just browsing the Innovatek Forum and somebodies waterblock exploded!!!!

Not like full blown explosing but it had rips in it on the side where the hose connections where and one side had a proper hole! It was a Rev 4.0 waterblock.



this block has leds in it. First they thought the leds overheated the plastic which cant happen cause the plastic is save over 150C heat.
Then he might have overtightened the connections which he did not do again!

obviously Innovatek took his whole kit and analysed it. etc and asked the user questions and found out the below.

Nach Untersuchung des Kühlers wurde eine Rissbildung aufgrund der Einwirkung einer Chemikalie festgestellt (typische Fächerung der Rissenden im Mikroskop erkennbar). Nachfragen beim User ergaben das zwar der Kühler selbst nicht gereinigt wurde -aber die CPU unmittelbar vor der Montage mit Spezielreiniger behandelt wurde.

bleibt festzustellen:
Ursache für den Ausfall des Kühlers war die Reinigung der CPU mit einem Mittel Namens "rubbing Alcohol". Dieses Mittel besteht aus 70% Isopropanol 30% destilliertes Wasser. Bei der nachfolgenden Montage wurden offensichtlich Reste des Mittels auf den Kühler übertragen. Dieses war Ursächlich für den Ausfall.

Hinweis:
Vermeiden Sie aber unbedingt den Kontakt des Kühlers mit Methanol (Umgangssprachlich Metylalkohol) oder Ethanol oder anderen einfachen Alkoholen!! Dies könnte den Kühler irreparabel beschädigen !!

which means:
they found out that the plastic on the block was in contact with cleaning alcohol, which causes a reaction and made the block break. The way it happened in this case is that the uses cleaned his CPU with "rubbing Alcohol". 70% Isopropanol + 30% destilled water. somehow left over of the solution touched the plastic on the block.
Innovatek says to avoid any conntact with any sort of alcohols!

I am sure a bit of beer wont do any damage though.

Any idea of what the plastic is? its not plexi so most of us are fine

Are there pics of this 'exploded' block?

some pics and original thread

the cooler uses "Spezialkunststoff" = special plastic.

Must be the same stuff you find on most waterblocks. Just be carful guys!!!

My friends bong did the same thing, he put some alcohol in it to dissolve the grime and a few hours later we came back and a bunch of plastic peices were all over his counter. The alcohol must react with certian plastics? It wasnt made of PVC plastic but some colored very hard brittle plastic.

Acrylic does this.

Wow.... I think im gonna stay away from plastics all together. hmmmmmm Good to know. Im gonna go with an all metal version.
