EK-Predator Club & Discussion Thread - Page 510

post #5091 of 7089
(Apologies in advance if this is off topic but I couldn't find an EK-ACF specific thread. If anyone knows of a better thread please let me know)

Does anyone know what this is on my EK-ACF fittings? I'm not using a Predator (custom loop), but Predator uses the same fittings.

Additional loop info:
  • All EK-ACF fittings with EK-ZMT tubing.
  • Coolant is 90% de-ionized water with 10% Mayhems XT-1 Clear (Ethylene Glycol; EK Coolant uses Propylene Glycol which is roughly equivalent to EG except EG lasts longer.) The coolant should inhibit corrosion and micro-organism growth.
  • No dies have been used.
  • Loop has only Nickel, Brass, and Copper.
  • Loop has been in service for about 7 months
  • Loop has some minor air bubbles in radiators, unable to fully bleed due to radiator orientations.

Could it be oxidation residue from an old radiator? Radiators were cleaned with vinegar and hot water before being flushed and put into service after a couple coolant changes. I'm thinking maybe my old Swiftech MCR240-QP is leaching some sort of residue?

I personnaly never seen this but maybe it could have been caused by the XT-1 ratio you used. Normally it's 5% of XT-1 for 95% of distilled. I would probably ask this question in the Mayhems Club thread. Maybe some users experienced the same issue.

Thanks, will do - and 5% is just a minimum guideline, more usually offers better protection. coolants like EK often have 15%-30% PG or EG mixed in. CLC's use an even higher ratio I believe.

Anyone tried a Predator 360 in a Caselabs S5 top position? It looks like it may fit but would be really tight. I have the 360 rad drop-in bracket for the top. EK's site indicates it will fit the S8 but no mention of the S5. Same indication for the 240 though so I don't know if they have data on the S5. The 240 will fit no problem but I would prefer the 360 if it will fit.

Thanks!

From what I see it should fit (very tight!!!!) but this afternoon I will try it to confirm it to you. thumb.gif

My Predator 240 just arrived and i had a question.

I have quite a few EK matte black fittings ready to go but the fittings on the pump and rad seem to be a special type of swivel fitting to allow some movement for flexibility. Should i bother changing them out to matte black or just leave them because it might not be worth the hassle to drain, re fill and work the air bubbles out ?, Ive done nothing but custom water cooling for years now but finally wanted to settle down and keep it simple

Here is a pic of my board which has some stainless steel silver accents so the polished fittings might not look to out of place -

I would keep the silver fittings it will fit perfectly with your board. A nice color reminder is always welcomed. thumb.gif

EDIT : Nice board and RAM by the way biggrin.gif

I also made a small attempt to remove those rotary fittings on the pump and couldn't get em off. Hell even the regular fittings were a pia.

Another vote for sticking with the nickel acf fittings.

I can officially confirm the predator 240 fits in an In Win 805 if you guys haven't added it to the compatible list.

How are you guys controlling the fans and pump via 1 pwm header ?, wouldn't the fans and pump adjust to the same speed when you make adjustments ?
