Is Mayhems Pastel ok to use with Feser Tubing?

Hello guys I need some help clearing up what tubing is ok to use with Mayhems Gigabyte Orange AWESOME Pastel?

I have read that some types of tubing can cause problems ( http://forum.overclock3d.net/showthread.php?t=50305 ) and that XSPC Thermochill Flex seems to be good and the choice of many.

The reason I am asking is I have read a small list of tubing that one should avoid as well tubing that is ok to use but at the end of the list it has "etc."

I have Feser tubing of 3/8ID - 1/2OD ( https://www.dazmode.com/store/product/feser_tube_hose_-_3_8_id_-_1_2_od_-_clear_1_-_not_uv/ ) and BP Compression Fittings that are 3/8ID - 1/2OD in my rig right now and I am building it again but with a NEW case, rads, res, Mayhems Gigabyte Orange Pastel and some other bits here and there. XSPC do not make tubing with 1/2OD, they have 3/8ID - 5/8OD. Yes I could buy all new fittings and go with 1/2ID - 3/4OD XSPC Thermochill Flex ( https://www.dazmode.com/store/product/thermochill_flex_1_2_od_-3_4_id_tube_-_clear_not-uv_/ ) but it would be nice to use the fittings I have and just buy extra ones as needed versus buying all new fittings only because I'm sitting about $200 over budget and still need new tubing(not a big deal) and fittings(the big deal if I need all new ones).

At the same time would the bigger tubing size be better as far as performance with the watercooling hardware I'm using as well as "better looking" because the new case is rather large?

Case: CaseLabs Merlin ST10(White Matte Obviously) --- thx to the review of the Merlin SM8!
Rads: 2 x AlphaCool 480(4x120) 80mm Thick
Pumps/Res: 2 x D5 with BP Dual D5 pump top with 250 upgrade kit

Cooling:

MB: Gigabyte X79-UD7 ( https://www.dazmode.com/store/product/ek-fb_kit_ga_x79_ud7_-_acetal/ )
CPU: 3930K (EK-Supreme HF)
GPU's: 2 x GTX 580 (EVGA HydroCopper2)
RAM: Corsair D:GT (2 x BP Galaxy Freezer DIMM2)---Maybe(Probably not)

As I am typing this out I'm leaning more and more to getting all new fittings(1/2ID - 3/4OD BP Compression Fittings) and tubing(1/2ID - 3/4OD XSPC Thermochill Flex) just holding off the rebuild a little for $$$.

But still would really like to hear what the community has to say. As well as getting an answer to the original question about the Feser tubing being ok with Mayhems Pastel for this build, other builds and future builds.

Thanks guys hope you can help :)
 
Doesn't mention Feser but this is from mayhem's site:

Do not use Mayhems Pastel with Primochill tubing or Tygon tubing as Mayhems Pastel seems to react with it changing the colour of the tubing to a greenish colour. This is not the fault of Primochill, Tygon or Mayhems it is just a incompatibility issue. Pastel works fine with XSPC, Thermochill, Clear Flex, Masterclear and a few other brands.
 
Mayhems Pastel is not for 24/7 use. It's just for show rigs.
The cooling performance isn't great at all, it's purely for looks.

Get Mayhems X1, or distilled water and add dye yourself to get the right colour.

You're talking about Mayhem Aurora. Pastel can be used up to 2 years and is just Ice Dragon nano fluid + dye. Cooling perfomance doesn't differ that much between Pastel, X1 or distilled water.
 
Pastel is also just for show use.

Theres new hose coming through thats meant to be ok but for long term use for the average user both are best avoided. Massive shame until the hosing situation is sorted and thoroughly tested (which takes months)
 
Well I don't really agree as Aurora is sold as 'show coolant' and Pastel is not.
The whole clouding / plasticiser problem has more to do with the tubing than the coolant.
 
Thanks everyone for the info and thoughts.

What would "long term use for the average user" be 6-12months and what experience would one need to know?

Because unfortunately I ordered the Mayhems Pastel and I have it already... if it really is that bad I can order something else, but the point was to have a build that looked amazing. I see many others including your self using it and it looks sooo good.

That kit with different rads is what I am using for another build with Pink Mayhems Pastel and the person I am building this for is questioning using this as well. The tubing in the kit is the same type as the 1/2ID-3/4OD I mentioned in the OP. That was why I figured that would be the tubing to use.

What tubing do you use? And I know you change a lot of things around as part of your work so is that why you use it and don't really recommend it for others because it doesn't really sit in a build for too long?

Thank you for the replies.
 
if you want a fluid that you can not see through i would go for coloured tubing tbh for the long term... my temps went down around 10c when i went from pastel too distiller water

Pastel does not have a 10c delta from distilled water.

Yeah it isn't that I don't want to see the coolant, I see your point though. The pastel coolant still has it's place in a build. For me I want it to go through all the Acrylic and Plexi cooling hardware I am using in the build. The pastel has "that look" that other coolants going through the same items just don't have.
 
I'm about to ditch pastel black myself. it looks great in the bitspower crystal link between my gpus, but that's it, ROFL. Switch to black tubing and was a massive improvement for my build.

I'm trying out mayhems XT-1 now.
 
i love mayhems dyes, but im losing interest in using dyes, period.
using color tubing and X1 is pretty much my go to now. the color pallette of tubing
sucks, but the tubing color is usually more consistant between flushes than dyes.
and since moving to comps over barbs.. accentually a non-dye usage point.
 
Have you read this post?

Using pastel in the long-term with the correct tubing and a well setup loop will not be a problem.

Personally I rebuild my pc once a year. I take it completely apart, thoroughly dust it, new TIM and fresh coolant.

Yes I have read that, thank you. The "long-term" thing is not really the problem as I do the same thing as you do, even less then a year most of the time. I just want to know if the tubing I'm picking is the "correct tubing". I have talk with the owner that I am buying the tubing from and he only uses the Feser tubing(he does sell other types) and has only had people have problems with the Mayhems Aurora. So I think maybe the ones having problems are the ones not making sure they clean ALL things in the loop even if some parts are new and by the end have rinsed everything with distilled water if they used any types of chemicals or additive originally. I am ordering some of the Feser tubing (clear) and I'm going to try it out. Another thing I was thinking was adding 1L(1000ml) of water instead of 750ml to the 250ml Mayhems Pastel Concentrate?
 
i love the pastel but when i switched from it to distilled my temps where about 10c lower also it stains tubing with a light milky tinge on a few brands i tried, cant remeber which but it was after a short period of time.so from my experience it does look the dogs danglies but the di mixes are way better
