Spare Screw Kit for Alphacool NexXxoS XP³

This spare screw kit is designed for the Alphacool NexXxoS XP³ CPU water block and works with other CPU water blocks. It includes an Allen key, plastic washers, knurled nuts, springs and four screws. The kit weighs 38g and features a black finish throughout.

Replaces Lost or Damaged Mounting Hardware

The kit replaces the original mounting set if screws, springs or nuts are lost or damaged during maintenance. It is worth buying when the existing hardware is stripped, corroded or missing, ensuring the water block can be secured again. The black coating matches the original aesthetic of the XP³ block.

Limited to M4 Thread and Fixed Spring Length

The knurled nuts use an M4 inner thread and measure 8x12mm, while the supplied springs are 15mm long. The four screws are M4x45mm, so the kit only fits blocks and radiators that accept this exact thread and length. Builders needing a different thread pitch, spring rate or screw length cannot use this kit.

商品問答

Will the M4 knurled nuts with 8x12mm dimensions fit my existing CPU water block mounting holes?

The knurled nuts have an M4 inner thread and measure 8mm in height by 12mm in diameter, matching the Alphacool NexXxoS XP³ specification.

Which Allen key size is included, and do I tighten the 45mm screws until the 15mm springs are fully compressed?

The kit includes an Allen key for the M4 screws; tighten until the springs are compressed to provide even pressure, not until they are fully solid.

Are the black M4x45mm screws and springs rated for long-term coolant exposure, or will they need periodic replacement?

The screws, springs and knurled nuts all feature a black finish designed for liquid-cooling environments; inspect annually for corrosion and replace if any discolouration appears.
