## Description

From the manufacturer

Review: Perfect for high end (but still fairly cheap) gaming when paired with a B360 motherboard - Great CPU overall, six cores with an all core boost clock of 3.8 GHz makes it an amazing chip for more affordable gaming even with a more high end graphics card. I have it paired with a GTX 1070 for max. settings, 75Hz gaming at 1080p and this CPU handles it very well, reaching basically 100% GPU usage in most games (other than GTA V). The only problem so far is that in certain games, such as The Witcher 3, there is a fair bit of stuttering, although I'm almost certain that is down to the fact that I'm running a single 8GB stick of DDR4 memory, which I plan to add another stick to very soon to run in dual channel mode to reduce the CPU usage and stuttering as well as increase my FPS. The only other minor problem that I have had is with the stock cooler that Intel supplies, the problem that I have with it isn't with performance or noise, but with aesthetics, in my opinion it just doesn't look very nice in a windowed case which is why I replaced it with a Hyper 212X from Cooler Master, not only making my system look a lot nicer, but also dropping thermals whilst gaming by about 10C (roughly 65 to 55C). other than these two easily remedied problems that weren't even caused by the CPU itself, it is almost perfect and once I have upgraded to dual channel memory I think it will be even better delivering a smooth gaming experience even when paired with a GPU such as the GTX 1070.
Review: Excellent value for money for such a powerful CPU. - This as at May 2018 is probably the best value to performance processor in the new 8th generation range. It happily plays Farcry 5 in ultra mode on my PC and it also came with a stock heatsink and fan. I chose to use a higher quality copper heatsink and a very large, quiet fan for cooling rather than using the stock items, but it is nice to have them included as some people prefer the basic, albeit noisy convenience of stock. I can honestly say that in my system this runs extremely cool, and even after having played intensive games for over an hour the heatsink was still cool as I tested my system by leaving the side panel off so I could feel any heat absorbed into the heatsink. I always by Intel processors rather than AMD, but that is just my preference.

## Questions & Answers

**Q: Does this come with a CPU cooler?**
A: I5-8400 comes with a cooler. They're sufficient for basic use, however i'd opt to get an aftermarket aircooler or an AIO just for sanity sake.

**Q: Was going to buy from you buy 12 pounds for shipping is too steep, I will go elsewhere?**
A: Depends how fast you want your parts.

**Q: Can i swap out my i5 7400 for this cpu**
A: no different cpu socket

**Q: What chipsets does it work with because i have a h110**
A: The 8400 will not work on a H110 motherboard. Only the older Skylake and Kabylake series CPUs (6xxx and 7xxx) will work on that chipset. 

You need a more modern chipsets like the z370, h370 to support coffelake cpus (8xxx)

### ⭐⭐⭐⭐ Punches above its weight, runs cool and performs well
*by A***R on 5 September 2019*

This is a really great budget CPU even in 2019. Pared with a decent graphics card, you'll be running triple A titles on high at 60 frames or more. It's 6 core, so it'll hold up fine with a few programs running, but might struggle with large rendering tasks etc due to its relatively low clock speed. Runs super cool, ive paired mine with a Noctua low profile cooler and ive never broken 65*. If you're looking at a console killer or a semi budget build, this is a good place to look with intel
