I've suspected that my watercooled build has been suffering from contamination - at the weekend I took a closer look.. For info i'm using ultra pure water, silver kill coils and Pulse Modding BioClear PT
First, here's the contents of my reservoir in a jug - the kill coils are lying at the bottom. Bear in mind the jug itself isn't clear but there's a reasonable murk:
and here's what the coils looked like:
Yuck. So this white crap is all over the shot - a very light coating in the tubing and also in the reservoir:
Here's the crusty bottom of my res:
and here's the inside of the fitting off the bottom of it (note that some sealant is round the outer edge and is a rubbery substance when dry):
So I washed out the system and then I've flushed it for about an hour with SysClean-HPD, and then flushed everything with 7.5Litres(!) of distilled. It's done a very effective job of cleaning things and i intend to refill with Mayhems XT-1 Concentrate Coolant + ultra pure. I'm dumping the coils idea on the suspicion I've had some horrible chemical reaction - other than that it's either flux from the rad (i did flush it prior to use though) or biological (doesn't seem likely and it's definitely not black/brown).
I probably ought to strip and de-construct the lot but it looks pretty clear now so I'm wondering if I can get away with HPD/flushing. I have a new res on the way as mine was old anyway.
So what the heck happened? Chemistry fail on my part? Opinion away..
Things were simpler with Redline Water Wetter.. (not perfect mind)
