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

[millertime359]

loop is filled and bleeding with pure feser blue.... Sometimes I realize this "hobby" has turned me into a masochist

You running Feser Blue in both loops?

Good for you ... this will be interesting to see what happens.

Can you keep an eye on evaporation rate as well?

Thanks for being the Gunk Master Tester for us

[LOUISSSSS]

so has there been an update from feser? a response?

[tamu80]

So how long are you going to wait to check on it Ian? If your willing to give it a go again....then I might put myself under the Masochistic flog as well
I don't think I will have my loops running for another two weeks or so.

I talked to them yesterday about the issuse, and they seem to think it;s been a reaction, and has never had any Problems with F1 before. This is the first time someone has brought it to there attention. So it's something in your loop. Tubing

[SNiiPE_DoGG]

K guys, I didnt drain the second loop for two reasons 1) I didnt have enough feser green left because I used it in my dads workstation build with primochill pro lrt RED tubing. 2) I was up till 5:30 am doing other things; draining, cleaning and filling a second loop would have put me up all night.

so the loop is running, crunching and my temps are great, loading at 55c on WCG I will be keeping a very close eye and reporting any problems whatsoever to this thread.

I will try to talk to feser today, work really screwed me in being able to skype at the normal hours in germany

[millertime359]

So i just called primochill and asked them about this. They told me "They don't test their tubing with competitors coolant, Feser 1 has a hazardous chemical, Glycol, in that tears systems apart." They won't even bring Feser 1 to their building because of that.

Edit: they also said they never heard of a reaction with their tubing and coolants.

[SNiiPE_DoGG]

lol thats some clever "It will kill you!!!! dont buy it!!!" .........."but weve never heard of any isssues "

[YMAA]

Or did they mean they've never heard of a problem with using their tubing and their coolants? I mean, I don't like using those premixed coolants, but I wouldn't go so far as say call Fesser one can tear systems apart. Meh, marketing BS.

[millertime359]

Just quoting what the rep told me. LOL. Yea they say use their coolant with their tubing.

@ S_D

Yea I tried not to laugh on the phone when he told me. Seems they really don't like Feser 1

This is pure speculation, but I wonder if it can be something in GTZ copper base or Acetal top, that may act as calalyst. When I run my blocks round up (each block for few days) only GTZ got oxidation of the copper base, other blocks were as new. Perhaps, copper have got contaminated with something else and went in production... ?

Beat me to it .. I don't see anyone with problems other than GTZ users.

I was wondering the same thing, possibly an alloy? It's not the ethylene glycol. I just changed the coolant (10% mix with green antifreeze) in my loops after about 6 months and went through all the blocks and saw nothing but bright shiny copper in all of them and I am using Primochill tubing as well.


EDIT: blocks are Dtek fuzion V2, and Ek Asus 1 on first loop and 2x Ek fc for 4870X2 on the second, Ek cylindrical reservoirs and D5 pumps, radiators are feser.

I'm using the GTZ, crunching 24/7 @ 3.6 GHz. I'd expect I'll see a problem at some point if it's simply heat + GTZ. I'm using Feser tubing, but I'm still not convinced it's the Primochill causing SD's problem.

If I was a betting person, I'd suspect a bad batch of coolant ... BUT, if I see the same thing in a month or two, we'll know there is an issue.

Snipe I found this in another post from about a month ago:

Try cola, honest it really surprised me! I'm not sure why but the GFX-2 on top of my GTX280 looked inside like someone had been using it as a cigarette filter! Really clogged with some black tar looking stuff! I first tried ketchup, didn't touch it, then vinegar, same. Coca-cola FTW lol

Sounds like wez3570 had the same issue but on a GFX-2! I wonder what kind of fluid he was using?

[SNiiPE_DoGG]

wow, good find so its not just me

[tamu80]

wow, good find so its not just me

I sent him a PM...hopefully he sees it and we can find out what fluid he was using.

[neo_rtr]

Iam using Feser One F1 UV Blue and Feser Tube FT Active UV Hose , even have few TFC Fittings.

Any way , can it be a compatibility issue? so the moment you mix some things then one part does not like the other and so on

[JoeChuo]

The black stuff on the block look nasty. Yuck! I remember something similar last time on the swiftech block too. Could be algae? I think we need mini filtration system on our loop.

[icrunk]

Does this happen with the Feser one Dye?

[Darth_Penguin]

Its crazy how no one has solved Sniipes Riddle. Lots of theories but nothing solid yet.

I think it's because it's a conundrum wrapped in an enigma wrapped in a riddle wrapped in a mystery. Geez, the Tootsie pop owl solved the age old question "how many licks to get to the center of a Tootsie Pop?" quicker than you can read this thread, maybe we should talk to him about this?

[wez3570]

XSPC glossy black tubing.

Pure Distilled with 3 drops of PT nuke.



The black tar stuff really baffled me, still haven't got to the bottom of it. Hence to say I've been a bit hesitant about filling the loop on my i7 build. I'm using the same pump, rad and the GFX2 had been thoroughly cleaned(thanks coka-cola, money's in the post)

I'm thinking about giving kill-coils a go, not even sure if that would prevent it.

WCUK has stopped selling Fesser liquids and now stock Primochill (none at the moment?) or Coolaboratory. Just checked my bottles and found this, contains:
F1 - ethylene glycol <0.005%
CL - ethane diol.

CL Pro Blue label says: There are no particulate materials or pigments in the fluid, which could obdurate the pump or cooler. A dying of the tubes is possible during the process. Coolaboratory Liquid coolant is biodegradable.

PS - what is the best way to clean my blocks - vinegar, ketchup or Coca-cola ?

[OldnBold]

XSPC glossy black tubing.

Pure Distilled with 3 drops of PT nuke.

Again this points to a problem with the block not the Feser.
