A slight misfortune has visited tolips secret watercooling lair.

First WB install went almost perfect.
Slight problem with ASIC temp. Not bad just no improvement.
Turns out there is sand in the vaselene that came with waterblocks.
Was prepared with other grease anyways.
I had hoped stock grease was adequate for testing, guess not.
So far trivial expected issues.

Move on to second waterblock install and lady luck exits left stage.
One of the 90's I attached to the waterblock FAILED.
It did not seperate completely, I would have had water everywhere.
(yes I was working on it with loop running and other ASICs hashing away)
I have so much flow I have to run only one pump out of two else air bubbles do not collect in resivour.
Woulda been like turning on a garden hose if it had seperated completely.

After I replaced the failed part my PCB only indicated 5 VRMs.
If you ever had a hard disk failure on a PC you may know how I was feeling at the time.
I did not panic, just got out the vacuume and PC crevace tool.
It took a few tries to get the VRMs to go again.
I also let the working VRM's help boil away the water.

All is well now and I'll (much more carefully) install the other 3 today sometime.

Come monday it's time to throw more money at it and get better 90's for all the waterblocks.
I'll also try and extract a pound of flesh from vendor for selling such shit.

Second time I had an issue with 90's from this vendor.
First issue was restricted flow in otherwise bulletproof cool lookin 90's.
With the leak I am done playing nice, the shit is too fragile for the application.

What's interesting about this adventure is that it is same PCB that challenged me installing 12AWG power wires onto.
I ended up bypassing the PCB 12V copper and running wires directly to each VRM.
The good news is that it was not my mods failed only a temorary shit new part/rain delay.

All in all, for me, it's fun to visit the bleeding edge.

YMMV

just curious, any reason to use 90^o fittings versus straight in fittings to the waterblock?
