Common Applications

LTCP03-04I (Intel) and LTCP03A-04N (AMD) share an electroplated pure-copper micro-waterway base, with a POM top as the default option and a brass top offered as an optional variant. LRC 2.0 5V 3-pin addressable RGB sits under the top and syncs with motherboard A-RGB headers. Intel mounting covers LGA 115x/1200/1700 plus X99 and X299; AMD mounting covers AM3, AM4, and AM5 for Ryzen 3/5/7/9. Ports are G1/4. POM is opaque and more crack-resistant than acrylic, which makes it well suited to builds that get retorqued or transported frequently.

Frequently Asked Questions

Q: Difference between LTCP03-04I and LTCP03A-04N?

A: LTCP03-04I is the Intel version for LGA 115x/1200/1700/X99/X299. LTCP03A-04N is the AMD version for AM3/AM4/AM5 Ryzen 3/5/7/9.

Q: How does the POM top compare to acrylic?

A: POM is opaque, tougher, and more resistant to stress cracks from over-tightened fittings, but the addressable RGB underneath is less visible than through acrylic.

Q: Is a brass top available?

A: Yes. The LTCB03 variant of the same family uses a brass top instead of POM while keeping identical mounting and waterway.

Q: What lighting standard does it use?

A: LRC 2.0 5V 3-pin addressable RGB. Do not connect to a 12V 4-pin header.

Q: Loop maintenance warning?

A: Install an inline filter ahead of the block and verify inlet/outlet orientation; reversed flow or debris in the micro-waterway will reduce cooling performance.
