How about the issue with conductivity? I knew all of this a year ago when i first built my syetm but not i have forgotten

Why did you run that piece of tubing around the GFX cards? You could have had a piece about 5cm long if you hand put it directly in between the cards.

Damn straight! Although, even though the clear tops look awesome, i just can't NOT get the acetel... mmm, black goodness!

Not sure that he could have actually (the question i asked myself when i saw that pic for the 1st time...) i reckon that the pci-e lanes are so close together that the barbs would actually touch on those...

I did on the previous setup, but on the Maximus Extreme board, the Crossfire slots are even closer together, so you can't fit two barbs on the same side.

I'm sure you do, especially with the higher temps Rivatuner reports than a GPU only active cooler

P.S Wouldn't use Feser products, seen a few confirmed cases where the fluid has separated and they also get half their colours by over loading the coolant with dye.

Any links to hand?

Marci at a competitor forum said:
That's dye separation. Simple as. What's left is a base flourocine mixture possibly which tends to always be "brilliant yellow" (what is also referred to as UV Green - that biohazardy yellowy/greeny glow). Looks like they added a second powder based dye to then turn it from that to orange, or just used a HELL of a lot of Brilliant-Yellow dye powder in an excess concentration to make it orange.

If you buy Brilliant-Yellow UV Dye from any company (eg: Glowshop), it looks that orange color, until you dilute it. Then it becomes the "greeny" color, which is the color it's intended to be. If you put too much (and I mean a LOT too much) of that dye into a coolant, it ends up orange, and the excess separates out, and will also dye anything floating within that loop orange.

I've witnessed many pre-mixed coolants (but not Feser One first hand) such as FluidXP, MCT-5 etc where the contents have broken down over time and resulted in a pile of white-flakes at the bottom of the bottle that once in the loop and subjected to the heating and cooling effect within the loop have then become dyed a deep color based on the coolant's original color. If using premixed coolants that have been sat on the shelf for "a while" (6 weeks or more - and I'm including time sat on the shelf at the manufacturer prior to shipping, including shipping time itself, then time sat at stock room sat retail stores, then sat on your shelf at home) I highly recommend pouring the lot thru some filter paper before adding it to your loop.

This all smacks of the premixed coolant being regular clear coolant with bogstandard UV Reactive Dye added... nothing "special"... and by the looks of things, there's a lack of control as to how much dye is consistently added from batch to batch.

PTFE tape cannot have any affect on coolant color. Simple as that.

A while ago, and has since seen it happen with Feser as commented recently at XS:

S'not the first time I've heard this reported regarding the Feser products. Last time it was put out that they'd had a "bad batch" and that this had been corrected and all current shipping products were fine...

Personally, I'm one of those who adds nothing... just straight distilled.

Also, don't link to a competitor.

How about anti Algae? How do i deal with this. Pretty sure I'm going to go the distilled water and anti freeze route.

Predator · 18 Dec 2007 at 09:55

I use Feser and don't have any issues.

Corrected for truth.

There's nothing wrong with it. I should have put a

in there somewhere.

It's fine. I'm sure you have been following the thread so I'm sure you're aware of the fact that some batches have white flakes in the bottom of the bottle either due to poor/excess storage or some manufacturing fault.

Never had any problems with Feser Stuff my self.

topgun06 · 18 Dec 2007 at 19:17

Is WaterChill Anti Alga Fluid - WaterWetter any good?

Mekrel · 18 Dec 2007 at 19:30

I just use some anti-algae from an aquarium shop, if it's good enough to protect expensive and fussy tropical fish then it's good enough for my loop.

Not sure about the stuff above, not read anything about it.

weescott · 18 Dec 2007 at 19:32

I used waterwetter a few years back, its dated and well known for smelling like cats urine!
