If I overclock, will I need an aftermarket heatsink?

Question by Steve: If I overclock, will I need an aftermarket heatsink?
Here is my build:
ASUS P8Z77-V LK LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS

HIS IceQ Boost Clock H795QC3G2M Radeon HD 7950 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video …

Intel 330 Series Maple Crest SSDSC2CT120A3K5 2.5″ 120GB SATA III MLC Internal Solid State Drive (SSD)

Microsoft Windows 8 64-bit (Full Version) – OEM

Crucial Ballistix Sport 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model BLS2KIT4G3D1609DS1S00

Seagate Barracuda ST1000DM003 1TB 7200 RPM SATA 6.0Gb/s 3.5″ Internal Hard Drive -Bare Drive

ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner – Bulk – OEM

Antec Nine Hundred Two V3 Black Steel ATX Mid Tower Gaming Case

Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000

CORSAIR HX Series HX750 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply

I am going to be doing a decent amount of gaming. I have another question posted about whether or not I should get the i7-3770k but that is besides the point here. I have never overclocked before but know a good amount of computers so eventually I think I am going to try it. I here bad things about stock heatsinks though. Is there any harm in trying overclocking? As long as I monitor the cpu temps and make sure they dont get past 80 degrees celsius I am okay right?

Just don’t overclock, it isn’t needed.

And yes you would need an after market cooler.

And no, 80 degrees is far too hot to be running all the time.

    You have picked out a fairly good build here. Nice to see that you didn’t cheap out on the power supply and the rest of your parts look decent as well. I’m not to familiar with the graphics card brand you’ve picked out for this build. You usually want to go for bigger brands because they usually have better customer service (most of the time).

    Now, since your build is medium-high end (More towards high end), I would not use the stock cooler even if I wasn’t overclocking, just because spending an extra thirty bucks really gives noticeable temperature drops. In the first few increments of overclocking, the temperatures will not go up too high, but once you reach a certain point, the temperatures will start to increase exponentially as you crank it up even higher. This is no problem at all if you have an aftermarket heat sink cooler. If you are not going to be overclocking too high (4.6+), then a Coolermaster Hyper 212 evo is probably the best choice out there. It delivers great performance for a small price tag. Now, if you are going to want to overclock as high as you can get your CPU (enthusiasts usually), you will want to get something like an H80(i) or H100(i) or even a custom watercooling loop which will cost more than your CPU itself (I assume you’re not going that far?).

    You will probably reach a max temperature of around 75 – 80 degrees with the stock cooler at STOCK speeds (around 50 idle), while you can probably get 30-35 idle and 60-65 load with the hyper 212 evo.

    One thing you should know is about the i5 and the i7. They have absolutely NO performance difference in gaming because of the fact that most games don’t use more than two cores. The main thing the i7 offers over the i5 is a feature called hyper threading. Although there are four physical cores, the computer recognizes it as an 8 core processor (8 virtual cores). This is because there are two threads per core, adding up to a total of 8 cores. The only time in which your i7 will be beneficial is during rendering and heavy video editing that require lots of cores.

    Overall, you’ve picked out a nice assortment of parts here (I’m usually pretty picky. :P) and everything should work nicely. Once again, I would recommend a hyper 212 evo just for casual overclocking in a decent build like yours. If you want to go higher, look into some closed loop water coolers and maybe a Noctua NH-D14 (Arguably the best air cooler on the market). If you want to go even further, custom water cooling loops will be your last option. Good luck!

    EDIT: Forgot to tell you, the max temperature of intel processors are 100degrees celcius, but most of the time it won’t go over 80, even with a stock cooler.
