Enermax Liquid Tech TR4 II 240

Overview

EMX-ELC-LTTRTO240-TBP-00 is an Enermax LIQTECH TR4 II 240 liquid CPU cooler / fan-radiator assembly used in Exxact workstation and server builds. In these tickets it appears mainly as a failing AIO cooler with pump or fan problems that cause overheating, restarts, shutdowns, or noisy / non-spinning radiator fans, and later as an EOL part that often required substitutes, fan-only repairs, or special RMA handling ([17059], [17233], [23129], [29733], [38609]) ...and 13 more.

Known Issues

• cpu-cooler-failure, 18 tickets. The dominant pattern is pump or whole-cooler failure causing high temperatures, hot tubing, boot issues, restarts, or thermal shutdowns ([17059], [17233], [23129], [29733], [38609]) ...and 13 more.
• fan-speed-issues, 12 tickets. Many cases were narrowed to radiator fans that squeaked, rattled, rubbed, failed bearings, stopped spinning, or ran intermittently ([18894], [19895], [25783], [33433], [37591]) ...and 7 more.
• overheating, 11 tickets. Reported outcomes included CPU temperatures above 90°C, system power-off after a while, temperature-related restarts, and load-triggered thermal instability ([17059], [19895], [25783], [29047], [38781]) ...and 6 more.
• incorrect-hardware-shipped, 2 tickets. Later EOL replacement handling led to wrong-size cooler shipments, including a 360mm replacement for an original 240mm unit and another first replacement that did not fit until corrected ([29047], [29733]).
• rma-workflow, 17 tickets. Most cases were handled as cooler-only RMAs, often with questions about return contents, inbound shipping responsibility, advance replacement eligibility, manufacturer turnaround, or whether fan-only replacement was allowed ([17059], [23129], [32296], [33433], [35714]) ...and 12 more.

Common Questions

• What does failure usually look like on this part? The most common signs are overheating, temperature-related restarts or shutdowns, hot tubing suggesting pump trouble, or radiator fans that become noisy, intermittent, or stop spinning entirely ([17059], [17233], [19895], [23129], [35130]).
• Do I need to return the whole system? Usually no. These tickets were almost always processed as cooler-only component RMAs, not full-system returns ([17059], [23129], [29733], [32296], [35714]).
• Do I return just the fan, or the full cooler? It depends on the failure. Some cases were handled as fan-only replacement when the issue was clearly isolated to one radiator fan, but pump failures or broader cooling faults usually required the full cooler assembly, including pump and radiator, to be returned ([17059], [33433], [33524], [35130], [37591]).
• Is this part still directly replaceable? Often not. Multiple later tickets explicitly say EMX-ELC-LTTRTO240-TBP-00 was EOL, which forced Exxact to use substitute coolers, replacement fans, or rebuilt assemblies instead of exact same-model stock ([29047], [33524], [34287], [37591]).
• Are replacement-fit problems common once it is EOL? Yes. At least two tickets document wrong-size or non-fitting replacement paths, and another required a second corrective fan shipment because the first substitute fan cables were too short ([29047], [29733], [37591]).
• Can Exxact still do advance replacement? Sometimes. Some customers received advance replacement or CRMA exceptions, but others were told the defective unit had to be returned first and that advance replacement did not apply ([18894], [32296], [35714]).
• Is installation guidance commonly needed? Yes. Customers asked about disassembly, cooler removal, 3-pin pump header routing, thermal paste, and whether an unusual missing pin on a shared fan connector was normal ([17233], [23129], [35130], [35714], [37591]).

Related Products

• ELC-LTTRTO240-TBP, the closely related base Enermax model. Ticket evidence shows both forms used for the same cooler family, with EMX-ELC-LTTRTO240-TBP-00 appearing as the more explicit internal / alternate part notation and ELC-LTTRTO240-TBP appearing in parallel support records ([34287], [35714]).
• Asetek 35-102-0000354 plus ARCTIC fans, the main documented substitute path after this Enermax unit became EOL. Exxact validated this combination for some systems, though fit was not universal and one 360mm replacement path was explicitly wrong for a 240mm original ([29047], [34287], [37591]).
• Replacement radiator fans such as ARCTIC ACFAN00305A P12 Pro, often used when the original cooling fault was isolated to the fan set or when Enermax’s original fan model was discontinued ([33433], [34346], [37591]).
• BEQ-BL094-00 system fan, a common companion RMA item in mixed cooling tickets where customers reported both AIO-cooler and chassis-fan problems at the same time ([18894], [24867]).
