The transparent, low-conductive pre-mix. Nothing to mix, nothing to measure — pour it in and run.
Swatches are visual approximations of the listed range — always confirm against a physical sample for a colour-matched build.
Ice is formulated with low chemical content so that, if it does escape the loop, it is far less likely to short a powered component than a heavily dosed coolant would be. That is a margin of safety, not immunity. Introduce dust, or mix Ice with another fluid, and its conductivity rises — the property belongs to the fluid as bottled, not to the puddle on your motherboard.
Thinner fluid moves through a restrictive block with less pump head, which means slightly better flow for the same pump speed and less noise chasing it. It also makes bleeding faster, because air separates out of a thin fluid more readily than a thick one.
A transparent coolant shows you everything — including the plasticiser and biological growth that an opaque fluid hides until it is advanced. Builders often read that as Ice being fragile. It is the opposite: you are seeing problems at week three that an opaque loop would not reveal until month four.
Fill slowly, bleed for 24 hours with the pump running and the system off. Check every fitting twice — a paper towel under each joint tells you more than a pressure gauge.
Ice is good for about 12 months running in a loop — sooner if you notice temperatures drifting upward with no other obvious cause, which is the practical sign it is time for a change regardless of the calendar. Unopened, it is good for 2 years from purchase. Top up with more Ice or plain DI water — a little dilution will not hurt performance, though heavy topping off with water will soften the colour over time.
