I'm watching some Computer building videos in order to be better prepared for when I build mine. I'm just wondering in all the videos they should them using thermal paste to glue a CPU Fan on top of the CPU.
I'm just wondering if a fan comes with your CPU (In my case its a i5 2500k). Or do I have to seperately go buy a CPU fan. And if I do, can anyone show me some fans that are reasonably priced.
Here in one of the many videos i've Watched are some pictures suggesting I need to seperately buy a CPU fan:
Unless you're planning to overclock or wanting a silent PC, the stock cooler will be sufficient, it does its job and nothing more. Otherwise, I would get a Coolermaster hyper 212 as others have suggested.
To make a long story short, the default fan with most CPUs is pretty crappy, and will do just good enough of a job to keep it kind of cool under normal-ish usage. It's also usually a small fan, so it has to spin really fast (making it loud) to keep up with higher-powered processors.
If you want to do really high-performance stuff, overclock, or just want your computer to be quiet, get an aftermarket. Like pretty much everyone in the thread had said, the Hyper 212 is cheap and pretty darn good. I use it on my Phenom II X6 (125W TDP) and it stays around 40C while torture testing.
