Common Applications
The N-MX4070TI-X is matched to the PCB of the Maxsun GeForce RTX 4070 Ti iCraft OC 12G. A nickel-electroplated high-purity copper cold plate is etched with a 0.5mm micro-channel structure and an enlarged MOSFET water channel that drives flow directly over the AD104 die, GDDR6X modules and VRM stage. A clear PMMA top exposes the channel pattern, and a black anodized aluminum backplate stiffens the rear of the card without touching coolant. G1/4 ports allow serial or parallel chaining, and an installed 5V 3-pin A-RGB (RBW) strip handles lighting.
Frequently Asked Questions
Q: Which card does the N-MX4070TI-X fit?
A: Maxsun GeForce RTX 4070 Ti iCraft OC 12G only. The PCB is unique to that model; do not install on other 4070 Ti brands or non-iCraft Maxsun cards.
Q: What surfaces does it cool?
A: GPU die, GDDR6X memory modules, and the VRM stage. The micro-channel area sits directly over the die for low thermal resistance.
Q: What materials contact the coolant?
A: Nickel-electroplated high-purity copper cold plate with a PMMA acrylic top. The anodized aluminum backplate is not in the wet path.
Q: What port size and RGB voltage does it use?
A: G1/4 threaded ports for serial or parallel chaining, and an installed 5V 3-pin A-RGB strip. Do not connect to a 12V 4-pin RGB header or the LEDs will burn out.
Q: Is the loop aluminum-safe?
A: No. The wet path is copper, so all radiators and fittings in the loop must also be copper or brass.
