I admit, I was reticent to buy it refurbished. But it's been working magnificently since updating from an i5 (the performance boost was noticeable from that start), no issues in several months I've had it. Totally worth it.

The irony is that I was only looking to replace my gaming controller but then I fell down the rabbit hole and the next thing I know I had spent an obscene amount of money doing and extensive upgrade to my trusty old rig. Either way the plan was to deck out my current build to its max so I can coast through the next few generations till prices adjust. The motherboard I had picked for my budget build had plenty of room for upgrades and I decided I would max it out so there would be no option than to build a new PC from scratch the next time I am forced to upgrade. This CPU wasn't a smooth ride initially. Until recently I was suffering from random reboots without any explanations or error notices (no BSODs either). After much testing and re-inserting/replacing hardware it came down to the motherboard being faulty. Since having replaced it with an Aorus Wifi Pro, this baby sings and is capable putting out better performance than the previous mobo withot any tinkering in the bios. The i5-9400f was a pretty capable cpu so I wasn't sure what sort of improvement to expect gaming wise. Its mostly GPU dependent. But turning on my current game (Yakuza 0) the frame rates were a lot smoother than previous. Its almost distracting how smooth the edges of the screen move as you run by places. Given that this CPU is easily capable of overclocking and the new mobo provides a decent headroom for that I am currently set for games till 8k becomes a standard thing. All in all slapping this thing in with a good cooler, I was considering an AIO but I figure looking into the best of the air coolers possible and it turns out the Noctua NH-U12A was a great fit for my needs.

This processor is a beast. Ive been able to run ICUE, a game on epic settings, and youtube in the background eith no issues. Intallation was a breeze, quite literally a pop and a click and it was ready to go! I am running it with an Asus Prime z390-a and i am very satisfied with my first build. You get what you paid for, all they way down to the last cent, which is to be expected from intel, and as always, they deliver that amazing quality! Will definitely be buying more for future builds!

Well I received the correct product, in the same packaging shown (not the large hexagon packaging that came with the initial release), this helped lower shipping costs which I appreciated! Despite feedback that R0 stepping 9900K's were not binned as well as their "KS" variant - I got this core to clock in at 5Ghz all core at 1.284v. Worked well with my Samsung B-Die RAM as well (@3600Mhz 16-16-16-36 timing). I got it to pass a 5.1Ghz all core OC, but the voltage required was immense at 1.38v which I wasn't comfortable trying to daily, maybe I need more time to tweak it but given the minimal gain it would be mostly for showing off than true performance difference. CPU Related Components: Motherboard: Z390 Aorus Ultra GSkill Trident Z Neo: 2x16Gb 3600Mhz 16-16-16-36 RAM Cooling: EKWB Monoblock, 240mm and 360mm SE Rads and some other stuff (see pic of RGB barf) Temps: Idle mid 20's, close to ambient. Under CPU Synthetic load mid to high 60's, when GPU is loaded as well (gaming) it will climb to mid 70's but that is because I've side mounted my GPU and my case is known for cooking GPU's anyway. R23 Score all core - 13240 @ 5Ghz R15 Score all core - 2134 (2153 @ 5.1Ghz, so not a huge bump at the expense of longevity hence not bothering trying to stabilise it) Given CPU prices lately I'm extremely happy with the purchase!

One thing I am always worried about, bying comp stuff on amazon, is getting fake stuff. I saw a few 1 starts of people complaining about getting fake/used cpu's, so it made this purchase feel like that much mroe of a gambal. What I got was real (at least if it is fake, they went all out to make sure every single detail, down to each pin, matched perfectly. So I'm sure it's real). The package was not wrapped, but was sealed using intel tape (pretty typical from what I've seen before). The box was slightly damaged, but nothing that would effect the cpu, and nothing that can't be explained by a long shelf-like pre-sale. It is 2022, and I don't think intel is still making 9900's. So even if it is used, so long as it preforms well enough that I can't tell, I'll take it. Will update when installed tomorrow.

Long story short, this replaced my i5-8500 in my 2019 27" iMac. So far, it works swimmingly. Significantly faster (while it was open, I replaced the NVMe/SATA HDD combo as well, so speed increases aren't exactly cut and dried.) Other than Apple's interesting choice in CPU retention (only uses the unweildy heat sync, so you have to be really careful attaching it), it's a straightforward drop in replacement. Not much more to say really. It works. Heat hasn't really increased much at all. So far it has been a worthwhile upgrade.
