Intel Core i9-9900 Desktop Processor 8 Cores up to 5.0GHz LGA1151 300 Series 65W

Excellent. It was worth it to pay a little more compared to sketchy sites like aliexpress (and ebay at times). I got what looked like a like new product and my desktop has never run better 🙏

this worked out well, a nice upgrade without much fuss using the same 1151 motherboard.

The processor speaks for it's self. The fact that the seller included CPU grease made my day. I appreciate that very much! Thank you!

nice- came well packaged, the thermal compound was a welcome addition, instructions on handling were clear

Vendor did a great job shipping this in a timely fashion and it was well protected. I needed to provide my own fan, but the seller included thermal paste. I'd love to purchase from them again if I get the opportunity!

Since this is not the unlocked version, it comes with a stock cpu fan. However, when running using that fan it would run hot when all the cores were running at full load, hitting up to 90ºC at the peak.However, changing the stock cpu fan for a better one solved the issue and now it run stably at full load and no hotter than 70ºC.

most affordable coffee lake i9. if you need just the basics and aren't looking for overclocking. get yourself this cpu

First time I've had to struggle with video and ethernet drivers on Linux due to Intel's increasing focus on proprietary Windows-only supported chipsets and drivers. Google Intel UHD 630 Linux support. Very iffy. Involves changing grub menus, kernels, installing various drivers, and then it may or may not work depending on your flavor of Linux. Personally I never got it working, so can't make any adjustments to the video, for example the Color Temp cannot be changed.Here's an example of what people are posting about it: "I have spent most of my day UHD Graphics 630 testing and paired with the Ubuntu 17.10 base I have tested its stock kernel as well as the vanilla/upstream Linux 4.13.0, Linux 4.14 Git, and DRM-Next kernels. Additionally, both with the Mesa 17.2 stable Vulkan/OpenGL driver stack as shipped by Ubuntu 17.10 and as well with Mesa 17.3-dev Git via the Padoka PPA as of earlier today." Sound fun?Same thing with Ethernet, didn't work out of the box with Linux, more chipset issues related to these newer CPUs. Never actually bothered to get it working, just plugged in a USB-ethernet adapter to get around it.Also, this may be specific to my system but the boost and base clock speed was not showing correctly on the Linux version I use, and I had to load the latest version of Ubuntu from Live CD just to see that was ok.Sept 23, 2020 update:This is probably no fault of this chip, but I've had two of these chips fail. Intel replaced the first one, and gave us a refund on the 2nd because I told them I didn't want another one. Both failed after about 6-8 months. It took me a day to figure out why the machine was failing because I didn't suspect the CPU.The symptom was the machine gradually starts having trouble completing the boot sequence and starts freezing while in use. I'm using a great cooler and monitoring temps so it's not that.I suspect the cause is probably the motherboard because the likelihood of 2 CPUs failing is so low. Platform is the ASRock Deskmini. I suspect maybe the motherboard is the culprit and is somehow damaging these CPUs over time, even though officially it's supported for that motherboard according to ASRock.But I'm putting this out there just in case others are having failures and in fact it is a problem with the CPU. I will say that Intel support is frankly the best I've ever encountered from any company.
