Intel CoreTM i5-10400F

Let’s start with the seller; outstanding. Amazon advertised a 2 day delivery if I ordered within 2 hours. I did but the order defaulted to a week delivery. I contacted the seller who promptly upgraded my delivery for free and it arrived in excellent condition exactly as the seller promised. Superb service, thank you!The item; brand new and sealed as you expect to see if you purchased from a physical store. Simple and easy to install the chip which was automatically detected by the PC and the improvement was immediately noticeable.The cooling assembly looks the part with a larger heat sink area compared to the old CPU but sadly the mount was incompatible with my motherboard so I had to revert to using the old heat sink. Seems to be fine so far but I’ll keep an eye on it. The reason for the incompatibility is my original mounting is achieved using 4 spring-mounted Philips screws but the new cooler is supplied with plastic press studs that were too wide to insert into the threaded holes.The new cooler comes with the thermal paste pre-applied so simply a case of scraping it off with a knife and spreading it onto the old heat sink. Shame as the Intel cooler assembly looks a lot cooler (excuse the pun) than the standard Dell one but this is no fault of the seller

dead cpu i tested it on two motherboards tehn put a diffent intel cpu in and they worked fine be careful
