## Questions & Answers

**Q: Does this support intel® socket lga1200 for 11th gen intel® core™ processors  support the rog strik z590-a gaming wifi?**
A: Yes, the Intel i9-11900k will fit any lga1200 socket

**Q: What is the best cooler for this cpu that will fit inside an in win c589t.cq350tbl atx mid-tower case, on an asus rog strix z590 motherboard?**
A: You can either build your own 2 fan liquid cool by getting every part separate, or you can do what I did which im quite happy with:
Get a coolermaster ML240L V2. In addition, 2 slim fans because there is not enough clearance above the ram to use the fans that come with the cooler. Instead, I went with 2 Thermalright TL-C12015W-S RGB SLIM 120 FANS (15mm thick). However, the screws that come with the slim fans do not fit the radiator so you will need to buy new screws or do what i did and use those 1cm plastic spacers that i had lying around and use the finger-tight screws that come with the cooler. Hope this helps!

**Q: Will you be able to have this with another GPU, while there already being one present?**
A: I am running the i9-11900K CPU with an NVIDIA GeForce RTX 2060 GPU. Both the CPU and GPU are recognized and utilized.

**Q: Porque un i5 tiene hasta 10 en numero de procesadores y este i9 tiene uno solo. Por favor me pueden explicar eso.**
A: Hola amigo, acabo de entender tu duda. El procesador de hecho tiene 8 núcleos físicos que trabajan como 16 lógicos, existen procesadores como los Ryzen que tienen más de 10 núcleos. Sin embargo lo que hace la diferencia es a que frecuencia puede trabajar como base y como máximo e incluso llevar al límite con Over-Cloaking. Este procesador es de 11va generación y trabaja con una frecuencia base de 3,5 GHz y como máximo a una frecuencia de hasta 5,3 GHz. Entiendo tu duda porque el detalle del artículo de la tabla de amazon está número de procesadores 1, pero ese dato no es el real. Si bajas un poco más puedes encontrar el detalle técnico real del procesador, puedes intentar buscar en la sección (Más información del producto) que está justo abajo de las preguntas. Como comprador puedo certificarte que tiene 8 núcleos / 16 procesadores lógicos y soporta PCIe 4.0 y es compatible completamente con el socket LGA1200

### ⭐⭐⭐⭐⭐ Core i9 cpu perfectly received
*by C***R on April 3, 2026*

### ⭐⭐⭐⭐⭐ Perfect for what motherboard I currently have

### ⭐⭐⭐⭐⭐ Might be a defective CPU but dang this thing makes heat..
*by W***R on July 24, 2021*

The seller did an amazing job. The item came even sooner than expected. The bad news is that I installed it in my previously flawless running machine. The reason I upgraded from my current i910900k is that I wanted to enable the NVME.2 4.0 on my SSD. I already had the drive and a Z590 motherboard so why not right? I put the new i9 11900k In and it started and enabled the 4.0 on my NVME. Yay right! Literally with in a couple minutes I received a watchdog timeout error. (This is caused by CPU cores failing to communicate with each other.) I called Intel tech support who was less than help full. I updated all drivers and still didn't work. I did notice my CPU temp was running over 100c. Odd because I have the best nactura CPU cooler they sell. I decided to upgrade to a liquid CPU cooler and that brought my CPU temp down to around 85c. That still didn't fix the time out errors. I put my old CPU back and all is happy. I ended up sending the i9 11900k back but at least my i9 10900k is nice and cool even at 45% overclock. LOL
