Do I need an expensive CPU fan for overclocking?

I'm doing my first build so I'm certainly new to everything thus far. I understand that you should ditch the stock CPU cooler and buy a better one. If I want to overclock, will I need one of those fancy 100 dollar CPU coolers or would something like a Cooler Master Hyper 212 EVO or Cryorig H7 Tower Cooler work just fine?

I'll be overclocking a FX 8350.

You may not get more if you aren't lucky in the lottery. For fx cpus, temps will probably be the limiting factor but even those cheaper $30 coolers will get in the decent 4.5ghz range. Spending more to push the limits gets you smaller returns. Aio are definitely not the sweet spot.

Depends, the more you spend, the more of a overclock you can get, eventually it's just about temps, cause a couple will only go but so, far. The hyper 212 is known to be reliable, cool, and be decent at overclocking, and is cheap. A lot of people go with cheap AIOs ($40-80) and they seem to be the sweet spot and price, temps, amd overclock ability.

If you don`t like the idea of a large stacked cpu air cooler such as a CM EVO 212 cpu air cooler.
And have a very small and compact case, with at least a mounting space on the system case for a 120 mm Radiator and fan setup.

Then buy a water cooling AIO kit such as a corsair H60, cooler master ect.

As the pump and cpu water cooling block will take less space in the system case Ikemage1015.

Fitted to a FX 8350 eight core cpu. Idle temps of the cpu will be around 36 to 37c, for example sat at windows desktop.
and when overclocked and running the cpu with game load ect on it about +12 to 13c around 47c.

Also running with any 120 to 140mm chassis or system case fan setup, if you have room to fit system fans also in the case you have.

Providing the motherboard you have is of a good brand, and the chip set the motherboard it`s self uses.

An 970 A or 990 Fx chip set of the motherboard, 990FX recommended more so for stability, overclocking.

You should be able to overclock the FX 8350 cpu to around 4.8,4.9 or to 5.0 Ghz as a maximum overclock.

5Ghz being the absolute maximum if lucky enough with the cpu silicone quality of the cpu.

The core voltage of the cpu at the three Ghz settings can or should be set between 1.46v to 1.5v.

1.6 volts for a AMD FX based cpu as the maximum safe voltage to set.
But personally try to keep it in the 1.5v to 1.54v range.

Keep a close eye on the cpu temps at any overclocking of 4.8 to 5.0 Ghz.

80c as a maximum when the cpu is stress tested with prime 95 ect ikemage1015
The lower you keep the cpu in temps the better.

On average about a 800 Mhz increase over the stock frequency of a FX 8350 cpu at 4.2 ghz.

Is a good over clock if completely stable with a prime 95 cpu test on it
And voltage for the cpu core set at 1.5v without a system restart, or lockup, freeze of the system and temps bellow 80c if you can get it there.
