Genuine Dell OEM 3T8KM CPU Heatsink Fan

This new replacement part is built exclusively for the Dell Alienware m15 R6 2021 model. It restores the factory cooling performance for the processor in this specific gaming laptop. Buyers needing a heatsink for any other Alienware series or manufacturer will not find a fit here.

Dual-Fan Copper Heat-Pipe Assembly

The unit combines twin fans with copper heat pipes and aluminum fins to move heat away from the CPU under heavy load. A 4-pin PWM connector allows the system to adjust fan speed automatically based on thermal demand. The assembly weighs .75 lbs and measures 7.1 x 5.3 x 1.2 inches inside the chassis.

Direct Replacement With No Extras

The package contains only the heatsink fan assembly; no thermal paste, tools, screws or software are included. Installers must reuse original fasteners and supply their own compound. Technicians without laptop disassembly experience should seek professional help rather than attempt the repair.

Questions about this item

How do I install the 3T8KM heatsink fan in my Alienware m15 R6 and which step do people often miss?

Remove the bottom cover, disconnect the 4-pin PWM connector, unscrew the old assembly, clean the CPU surface, apply fresh thermal paste, seat the new copper pipes and aluminum fins, screw it down evenly, reconnect the 4-pin connector, then test fan spin before reassembling.

What maintenance will the 3T8KM cooling assembly need later?

Clean dust from the dual fans and aluminum fins every few months with compressed air; reapply thermal paste on the CPU if temperatures rise after a year or two of heavy gaming.

What limit appears first during sustained loads on the 3T8KM heatsink fan?

The dual-fan PWM curve caps RPM once the 4-pin signal hits 100 % duty cycle, so prolonged max loads can push CPU temps higher until the system throttles.
