Is a costly CPU fan necessary when overclocking?
I'm starting this project for the first time and completely unfamiliar with all the details so far. I know you should replace the standard CPU cooler with a better one. If I plan to overclock, will I need an expensive 100 dollar cooler or would options like the Cooler Master Hyper 212 EVO or Cryorig H7 Tower Cooler be sufficient? I'm specifically overclocking an FX 8350.
You won't reach higher speeds unless you're very lucky in the lottery. For fx cpus, temperatures are likely the main constraint, though even the more affordable $30 coolers will usually hit around 4.5ghz. Going beyond that to spend more doesn't yield bigger gains. Aio definitely isn't the ideal choice.
It varies; spending more allows for higher overclocks, but eventually it's limited by temperatures. The Hyper 212 is trusted, performs well in cooling, and offers solid overclocking potential at a reasonable cost. Many users opt for budget AIOs ($40-80), which provide a good balance of price, temperature control, and AMD overclocking capabilities.

If you prefer not to use a big stacked CPU cooler like the CM EVO 212, and have a very small case with enough room for a 120 mm radiator and fan setup, then consider purchasing an AIO water cooling kit such as the Corsair H60 or Cooler Master ECT. Since the pump and CPU water cooling block will occupy less space in the system case, Ikemage1015 recommends this approach.
This setup works well with an FX 8350 eight-core CPU. At idle, the CPU temperature should be around 36 to 37°C, for instance on a Windows desktop. When overclocked and running games, temperatures rise slightly to about 47°C. With a 120 to 140 mm chassis or system case fan configuration, you can still fit system fans inside the case if space allows.
Make sure your motherboard is from a reputable brand and that the chipset it uses matches your board. A 970A or 990F chipset is ideal, especially the 990FX for better stability and overclocking potential. You should be able to push the FX 8350 CPU up to around 4.8–5.0 GHz, with a maximum of about 4.9 GHz under optimal conditions.
If you manage to keep the CPU at 4.8–5.0 GHz, aim for temperatures between 80°C and 85°C during stress tests using Prime95. The lower the temperature, the better. On average, you can expect roughly an additional 800 MHz compared to the stock speed of the FX 8350 at 4.2 GHz.
If your CPU consistently stays stable at 4.8–5.0 GHz, a 5 GHz setting is the absolute limit—provided you have good CPU silicon quality and maintain safe voltages.
