What to know before buying

Listing details to confirm

The listing identifies the screen as LCD in the product title and IPS in a feature statement, so the panel type is inconsistent. The listed 310W TDP, 3100 RPM pump speed, 90 cfm airflow and 29 db noise are manufacturer claims, not independently verified measurements. Confirm case clearance and the selected motherboard socket before buying.

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller share are low ratings. Without customer comments, the ratings do not establish what buyers liked or disliked. Consider them only as a broad signal alongside the listed 3.5-inch screen, software requirement and socket compatibility.

Frequently asked questions

Which CPU sockets are listed as compatible?

The listing names Intel LGA 115X, 1200, 1700 and 1851, plus AMD AM4 and AM5. Check the exact socket and case clearance for your build before ordering.

Can the screen show custom content?

The listing says Ocypus Display software supports custom themes, MP4 video, JPEG, BMP and PNG images, and dynamic GIFs. It requires Windows 10 or Windows 11 and a USB 2.0 connection.

Does the listing confirm whether the display is LCD or IPS?

No. The title calls it LCD while a feature statement describes it as IPS, so the panel type is contradictory in the listing.
