good job you had non conductive fluid
this doesnt have any impact on the situation whatsoever. his fluid is two years old. fluid that has been in contact with metals and sat in a loop for two years is going to be conductive mo matter what happens. being non conductive would at best grant you a grace period before your hardware eventually died.
i have covered a pair of GTX 480s in fluid before and they worked afterwards. would i have tried to power them on when they were wet? no. of course not.
a spill like this is easy to rectify by using a sensible drying procedure and not being too hasty with turning your hardware back on again.
conductive or non conductive fluid has absolutely nothing to do with it.
I wonder if an acetal block would have survived.
yes it would have done without a doubt. pressure cracks on plexi are all to common in my opinion. repeated heat cycles etc make plexi a liability for long term usage rigs in my opinion. acetal is a far more sensible option. i have never seen acetal blocks suffer from this.
in fact i remember asking MIPS to make me a custom plexi topped memory cooler once and they essentially replied with a lecture on why they refused to work with the material.
the fact is, that crazing around the port on the block was probably there long before the pump even failed, the extra heat would have only exacerbated it.
Will ek replace the block?
doubtful really given the circumstances of the failure. but it has been known.
EK are very customer service focused and generally do what they can to make things right by the customer to enhance their own reputation.
