. The £25 one is some kind of engineered fluid if it wasn't from mayhems I'd claim it's a bit of pseudo science but they're a great brand been using them ever since I started watercooling so I trust it's legit science
.The £15 one is standard coolant everything you need. The £25 one is some kind of engineered fluid if it wasn't from mayhems I'd claim it's a bit of pseudo science but they're a great brand been using them ever since I started watercooling so I trust it's legit science

.I wouldn't have thought so. I haven't personally used that one so cannot say for sure.
The review does say he got a few degrees drop over standard fluid.
Depends how far you want to go. Personally I'm tight fisted haha.
Edit: quick Google brings up one test of the older version and it was pretty much the same as standard fluid.

No worries. If you swap to the more expensive one it would be great if you could post your findings. Any temp diff would be great.
What are you cooling? Can we have some pics when you're done?
Merry Christmas to you too mate.

Be very careful mounting the D5 to the reservior. I just used one and couldnt get a decent seal around the pump housing. It leaked out all around it. I'm not sure if my pump being an older one is a slightly smaller one but it was not a good experience. Check the seal NINETYFIVE times before you fill it up. and check it with liquid in before you put it into the rest of the loop.
It made me sad![]()


Right now the parts I ordered from the US (including the reservoir) are with the UK Custom, I will report in full detail once I got them. Merry Christmas.I used the shim and factory O-ring in its original position.
Shim under factory O-ring
D5 original O-ring on top of factory O-ring
D5 original O-ring on top of factory O-ring AND shim
Factory O ring and shim with D5 O-ring around the pump housing to provide pressure to the metal rings.
It just ****ed out, if you tighten it up like the instruction tell you so that the "motor" (pump) cannot be turned in the ring if pushes the shim over the outside of the pump face and that breaks the seal.
The replacement had no fittings included in the package.
I gave up after loosing a third of a litre of pastel orange and went for separate parts. Good luck to you but short of fabricating a new screw ring to hold the pump LEVEL without it eating half of the outlet or being so tight it cant spin I just could not get it working![]()
I change my parts (graphics cards, CPU, motherboard...) every 6 months, not completely but partially, and I like to clean my system every 2 months so I dont really need a long life coolant. Merry Christmas !is there any reason why one may not use a long life coolant instead?
i love tinkering and all but having to drain a system every year or even two would hint as something fundamentally unreliable.
