What to know before buying

Listing details to confirm

Listing details are inconsistent: title and feature text cite 25.6 Decibels, while the fan specification gives ≤29.8 dBA. The title says 115x/1200, while the compatibility text separately lists 1150/1151/1155/1156/1200. The explicit contents list says “CPU Air Cooler, CPU Fan, Close”, while descriptive text claims two fans and installation accessories, so the exact bundle is unconfirmed. The listing also says AMD installation uses the motherboard's original backplane, which is not included. Confirm the exact socket and package contents for the selected listing.

The supplied ratings are uniformly five-star, but the sample is small and there is no written feedback to explain what customers liked. Treat this as limited sentiment evidence rather than proof of cooling performance, noise or compatibility. For buyers, the cooler's listed socket range and 155 mm height are more useful checks for fit than the rating alone.

Frequently asked questions

Which CPU sockets are listed as compatible?

The listing names AMD AM4 and AM5, and Intel LGA1851, 1700, 1150, 1151, 1155, 1156 and 1200. Its title uses a narrower Intel socket list, so confirm your exact socket against the selected listing.

How much clearance does this cooler need?

The stated height is 155 mm. Check the case's cooler-height limit and ensure the dual-tower arrangement clears nearby memory and components.

Are two fans and the mounting kit definitely included?

The product description claims two TL-P12 fans and an installation kit, but the explicit included-components field is ambiguous. Verify the package contents before purchase.

What noise level does the listing specify?

It conflicts: one detail gives 25.6 Decibels, while the fan specification states ≤29.8 dBA. Neither figure should be treated as a settled measurement.
