The required hardware includes a Kraken x61 or similar for models over 4.7. An NH-D15 or R1 Ultimate from 4.5 to 4.7 would suffice. A 212 Evo or H7 can reach up to 4.3-4.4 max. This isn't accurate—I own a model with a Tx3 that performs worse than an 212 Evo, yet still manages 4.3 or 4.4. You're free to argue as you wish, but the point remains: the Tx3 is designed for a 130W cooler and was never intended for heavy overclocking. So it only truly serves to cool an overclocked Fx-8350 at 4.3-4.4 when idle or during stock/low settings.
Running SmallFFTs, OCCT, or AIDA64 will really stress things out. Don't forget the silicon lottery involved. If you're lucky enough to win, maybe the Tx3 can handle a 4.4 GHz overclock—though that's not guaranteed. At 4.4 GHz, the 8350 should easily exceed 1.4v. If not, you might be mistaken.
The Tx3 struggles with Intel CPUs at 1.4v under 70°C and full load.

@ dudeman: The 212 is better, but not significantly so. I've heard some users report the 212 Evo can keep an Fx-8 core running at 4.5-6, though that's far from easy. These are exceptions, and most people won't experience them. The Cryorig H7 actually outperforms the 212 EVO. If you're debating the overclocking potential of entry-level coolers, the H7 would be a stronger choice.
You're comparing an i7-4770k at 4.2 with roughly half the power draw of the Fx-8350.

These are the general guidelines you can expect. My statements are supported by benchmarks from reputable tech sources. If you disagree, try running benchmarks yourself. Otherwise, this seems like a stretch.
Additionally, when considering an AMD CPU overclock, utilize AOD. The thermal margins stand out as the most reliable for obtaining accurate AMD CPU temperatures during load conditions. C6 state and Cool n'quiet must be turned off to achieve optimal performance. If you require these protections to prevent overheating, then reducing the clock speed is necessary, as this negates the benefits of overclocking and indicates insufficient cooling from the start.
Benjiwenji adds further details about optimizing AMD CPU overclocking. He recommends using AOD for better thermal accuracy. The C6 state and Cool n'quiet should be turned off to achieve the best performance. He warns that keeping these features enabled can prevent proper cooling, leading to throttling and reduced gains. He also mentions replacing his cooler with a Nepton 120xl, which allows him to reach 4.5GHz at 1.45V with high Intel burn test temps, though fans run hotter in "cooler on" mode. He notes that enabling Cool n'quiet without adjusting voltage can still work fine if you're just browsing the web.

i tried with cool and quite disabled but now I’ve turned it back on, no issues there, right? Why keep it at a steady 1.45v if I’m just browsing the internet? The real point is why we overclock at all when I’m only doing internet browsing? Why bother with the Fx-8350? In a strict sense, the A6-6400k would work fine for web use.
We increase the AMD CPU’s speed because of its low IPC. Most applications and Dx11 only really use 1-2 threads. Overclocking helps us get the most performance from the CPU in Dx11 or elsewhere, where the workload isn’t spread evenly across all threads. This causes bottlenecks on just a few threads while others stay underused. That’s why we manually set the voltage to 1.45v or whatever is needed—it serves a purpose.

I don’t claim I only browse the internet, but if I’m browsing, why not run the CPU at full power?
On my Intel machine, I kept it at full speed all the time.
