★★★★★My i5 8400T was delivered as promised.
Intel "T" series processors win the "cool, quiet, dependable, long lasting" benchmark. Product is working great. All 6 cores are idling at about 20 degrees C (68 degrees F) with a Noctua D9L fan. Passmark CPU Mark was 10399 (Gigabyte Z390M motherboard).

★★★★★Good CPU. Good reseller. But not so fast.
I think i5-8400T is not suitable for gaming because it only has an E3 v3 performance. CPU-Z scores (Single core / All cores): 8400T: 380/2030 8400: 470/2680 E3 1285L v3: 395/1990
