Common Applications

The LTPRP-04I S and LTPRPA-04 S are the compact mini-version of Barrow's CPU block-pump-reservoir AIO. A 17W PWM pump sits inside a POM body with a nickel-plated high-purity copper base plate that contacts the CPU IHS, and a metal black cooling cover sheathes the pump motor to spread its waste heat. The Intel variant LTPRP-04I S mounts on LGA115x, LGA1200, LGA1700, X99, and X299 sockets; the AMD variant LTPRPA-04 S mounts on AM3, AM4, and AM5 sockets. Inlet and outlet are G1/4 threaded, and the PWM cable lets the pump RPM track the same fan curve as the rest of the loop rather than running flat-out. This is the no-lighting performance version with no OLED screen, intended for smaller cases where the full-size LTPRK series will not fit above the socket.

Frequently Asked Questions

Q: What is the difference between LTPRP-04I S and LTPRPA-04 S?

A: LTPRP-04I S is the Intel variant compatible with LGA115x, LGA1200, LGA1700, X99, and X299. LTPRPA-04 S is the AMD variant compatible with AM3, AM4, and AM5. The pump, cover, and waterway are identical between the two.

Q: How is the pump powered and controlled?

A: 17W PWM-controlled pump. Power and PWM signal are supplied through the 4-pin connector to a motherboard pump or PWM-capable fan header.

Q: What is the base plate made of?

A: High-purity copper with a nickel-plated surface for corrosion resistance against the coolant. The pump and block bodies are POM with a metal black outer cover.

Q: Does this version have an OLED screen or RGB lighting?

A: No. This is the S (mini) performance trim with no OLED screen and no integrated RGB. The full-size LTPRK series adds OLED and ARGB.

Q: What size are the inlet and outlet ports?

A: Standard G1/4 thread. Use compression or barb fittings of your preferred ID.
