Last night I thought I would check on the internals of my 2 blocks for my video cards. They have been sitting waiting patiently for Doris, so not been used in a couple of months. Before I put them away I rinsed them well with distilled water.
When I opened the 1st one I was greeted by this
The o-ring was pretty badly crudded up also, but hard to get a decent shot of it.
On the 2nd card the block wasn't so bad, more on the top though and quite a bit on the left side
Tonight I stripped down my HK and this is what I found
The little plate was pretty yucky also
The HK and plate were easy to clean as they had stayed damp, just not too sure how to go about the video blocks, wondering if to pour some DW on them and hope it will soften the crud.
Hoping this is just the result of having used Feser 1 and not something more serious. The video cards were on a totally separate loop from the HK. I broke down my mosfet block and that seemed fine.
These loops had been running for about 6 months, the openly visible side - tubes and res's were both completely clear, also just checked the pumps and they look good.
Changing to DW + coil for Doris

The stuff inside your Heatkiller is just dust and debrie that somehow got into your waterloop, and the HK acted as a filter, trapping them on the nozzle plate. It has nothing to do with your coolant. I got the same thing after a few months with distilled and silver coil.. it is just the necessary evil that comes with a modern fine min matrix/micro channel design waterblocks. I now have a steel mesh filter inside the loop which I can check on and clean easily, so my Heatkiller does not serve that purpose.

ugh, when will people learn to stop using feser crap!
Never. Been using it for years literally and not a single problem like this. Feser all the way. Something else must have caused it, i seriously doubt feser will cause that.
I've just cropped and enlarged the plate, which hopefully shows more clearly what looks like either algae or Feser gunk.
Yes, definately no more colored fluids for me!
The only places it has built up is in the CPU and VC blocks, all the fittings, tubes, pumps etc are totally clear. The one thing I had noticed was the bottom card had started running quite a bit hotter, so I guess that was probably the one worst affected.

doesnt look like typical coolant gunk. which usually looks more slimy.
that said, premade coolants are basically overpriced water with a color. just get some distilled from your local supermarket, some food coloring and a piece of silver. alternatively, you can use some copper sulphate instead of the silver.
I had faser gung, very slimy just like you say ChielScape. Colord tubing for me next time!

Whats the difference between copper sulphate or silver? Sorry for the newb ? lol
silver, you use it as a solid. a ring, coin, etc. (just make sure it doesnt clog anything)
copper sulphate you add as a powder (sometimes white, but generally blue) or as a solution, like PT Nuke. you need just a tiny bit. in powder form, a teaspoon of it is enough for 50L of coolant, at least.
Gunk....Feser 1, algae or worse?
