What to know before buying
Listing details to confirm
Listing details are inconsistent: one description gives heatsink dimensions of L120 x W46 x H151mm while the feature section gives cooler dimensions with fan of 120(L) x 71(W) x 151(H) mm. The listing also calls the product compatible only with AM4/AM5 while another line says it is designed for Intel platforms, and the nominal kit wording mentions a black cover that is absent from the explicit contents list. Confirm the selected listing, socket and dimensions before buying.

Who is it for?
A good fit for
- Desktop builders using an AM4 or AM5 socket who want a single-tower air cooler.
- Buyers whose case can accommodate a cooler listed at 151 mm high and who want a 4-pin PWM fan.
Less suited to
- Intel-platform builders, since AM4/AM5 are the stated supported sockets and Intel compatibility is not confirmed.
- Buyers who need verified dimensions or confirmation that a separately mentioned black cover is included.

The listing names AM4 and AM5. It also contains an inconsistent reference to Intel platforms, so do not assume Intel socket support without confirmation.

The fan is listed with a 4-pin PWM power connection.
Is the black cover included?
The contents list names a CPU cooler, while nominal kit wording mentions a black cover. Its inclusion is uncertain, so check the selected listing.
