Confirmed: Feser 1 Blue Premix + GTZ = do NOT want

[SNiiPE_DoGG]

Well guys, I tore permafrost's guts up tonight because the Blue Feser 1 had lost its color and my CPU temps were terrible; here is a log of what I found.


drained liquid NOT blue


That particulate crap in the liquid is blue


looks O.K. from here....


I cringed after removing this rotary - looks like corrosion an that part is still being sorted in a bath of vinegar before I know for sure. the stuff on the toothpick is from the 45.


You know that feeling you get when you know something is gonna be really bad? I has it.


Yeah, its worse than I thought. thats not a problem with the color in the picture, its actually pitch black goop and grime.


Here is what the base looked like after I rinsed it with water and scraped at it with a toothpick. everything you see there is a hard plaque-like substance. In the top right corner (where the injector barb is I presume) the "plaque" is almost a milimeter thick.




I pick at it with a small flathead screwdriver, it takes a LOT of gauging to get it all off.


Here's how I cleaned the base after taking pics. Take a guess what that stuff is - I'll give you a hint, its not barbecue sauce....

(its Ketchup )


Its clean..... finally after a half hour of scrubbing and scraping.


looks a lot better than the first pic i took looking into the block eh?



A few notes about the incident:
-This machine was crunching 24/7 (60C load all day and night) for at least a month before I noticed the clogging via higher temps.
-The loop has a mosfet block after the outlet. this block will be rinsed tomorrow, I looked in with a flashlight and didnt see any gunk.
-This was new style bottle Feser one Premix coolant of the standard blue color.
-My only conclusion to come to is that it is NOT ok to use this Feser ONE coolant at high sustained temperatures!
