«Tray» means the processor is sold without any additional packaging, cooler, or accessories—just the bare CPU itself. Tray processors usually come with a shorter warranty compared to boxed versions, which include a cooler and full retail packaging. Tray CPUs are often sold in bulk to OEMs and may have different warranty terms handled by the seller rather than the manufacturer. So yes, «tray» refers to just the CPU without extras like a cooler or retail box.
