Common Applications
The Classic Edition is offered as LTYK3-04I for Intel and LTYK3A-04 V2 for AMD, sharing the same electroplated pure-copper micro-waterway cold plate and acrylic top. LRC 2.0 5V 3-pin addressable RGB lights the top channel and syncs with motherboard A-RGB headers. The Intel kit ships with an adjustable backplate that covers LGA 1150/1151/1155/1156/1200/1700 plus X99 and X299; the AMD kit reuses the stock retention plate to cover AM3, AM4, and AM5. Inlet and outlet are standard G1/4. Pay attention to inlet/outlet orientation during install, as reversed flow reduces cooling performance, and add an inline filter to keep the micro-waterway clear.
Frequently Asked Questions
Q: What is the difference between LTYK3-04I and LTYK3A-04 V2?
A: LTYK3-04I is the Intel version and ships with an adjustable backplate for LGA 115x/1200/1700/X99/X299. LTYK3A-04 V2 is the AMD version and reuses the stock AM3/AM4/AM5 retention plate.
Q: What lighting standard does it use?
A: LRC 2.0 5V 3-pin addressable RGB, compatible with motherboard A-RGB headers and Barrow LRC controllers. It is not 12V 4-pin RGB.
Q: What is the cold plate made of?
A: Pure copper, electroplated to resist oxidation, with a micro-waterway pattern under the inlet.
Q: Does inlet/outlet direction matter?
A: Yes. The inlet must face the marked port so coolant hits the jet plate correctly. Reversing flow reduces heat dissipation.
Q: What thread and filtering does the loop need?
A: G1/4 inlet and outlet. An inline filter ahead of the block is strongly recommended to keep debris out of the micro-waterway.
