Is there a difference in quality between CPU, boxed and spare parts? So why are scattered films cheap?

The performance of boxed CPU is exactly the same as that of bulk CPU. The only difference is that the boxed CPU has an original fan, but the original fan has an average workmanship and heat dissipation effect. The scattered CPU has only one processor and needs to buy another fan. However, even the 30-yuan fan has a much better cooling effect than the original fan.

Generally, boxed CPUs are purchased from regular retailers such as JD.COM and Yixun, or users who are completely unfamiliar with computer hardware don't know that they can buy piecework CPUs, or they are not very comfortable about buying piecework CPUs.

Another point is that the boxed CPU is generally guaranteed for 3 years, and the scattered CPU is generally guaranteed for 1 year. However, CPU is the most trouble-free accessory. There are good and bad CPU, and there is no sudden failure after normal use for a period of time. Usually, if the CPU is not overclocked, damaged or flooded, it can be used until it is completely eliminated. I haven't seen an example of sudden CPU damage under normal use.
