Hello all,


I am having a custom gaming PC built, and I can't help but wonder about whether or not it will need a 3rd party heat sink for the CPU. The unit does have a built-in heat sink, but I have heard conflicting stories as to the effectiveness of it.


The system:


AMD FX-8320 8-core processor


240 GB SSD


750 W power supply



The individual building the system for me advised that the CPU's built-in heatsink will be sufficient, though more than one friend has told me that overheating may definitely be an issue. Does anybody have any input on this? I would rather invest in something now and not need it than I would go without it and realize it is necessary down the road. Any input is appreciated.

ive done many a build, including gaming rigs, with stock cooling. If your case has good airfow and you don't overclock it should be fine. With that being said, aftermarket cooling will help the CPU run cooler and likely longer-though this may have changed but at least in the past aftermarket cooling voided the CPUs warranty. Something to check before installing a after market cooler.


with that being said, I tend to run third party cooling on most of my systems especially if they tend to be on a lot or in a hot environment.



Primary system: Motherboard: ASUS M4A89GTD PRO/USB3, Processor: AMD Phenom II x4 945, Memory: 16 gigs of Patriot G2 DDR3 1600, Video: AMD Sapphire Nitro R9 380, Storage: 1 WD 500 gig HD, 1 Hitachi 500 gig HD, and Power supply: Coolermaster 750 watt, OS: Windows 10 64 bit. 

Media Center: Motherboard: Gigabyte mp61p-S3, Processor: AMD Athlon 64 x2 6000+, Memory: 6 gigs Patriot DDR2 800, Video: Gigabyte GeForce GT730, Storage: 500 gig Hitachi, PSU: Seasonic M1211 620W full modular, OS: Windows 10.

It'll work.  But one common complaint with the standard AMD cooler is that it can get very noisy (it's fan will spin up to over 5000 rpm under high load).  There's no way that is going to be quiet.  It's not going to be as loud as the old Delta fans people used to use (I had a cooler once with a 7k RPM Delta fan, and it seriously sounded like a jet idling), but IMO anyway, a fan spinning at 5000rpm+ is going to be unacceptably loud.


There's a video here, although the sound in reality is likely to be different than can be put across in a video.


An aftermarket cooler will be much better performing, and quieter.  There's no need to install the aftermarket cooler at build time - you could fit it afterwards, but it might be easier to put it in during the build.  Most larger coolers need back plates fitted behind the motherboard.  Better cases have a cutout to allow you to do this without removing the motherboard, but if not then it's a mobo out job.  You also need to be careful of their size and whether they are too large for the case, or interfere with RAM heatspreaders etc.

If you can afford it, Do it. Things running cooler in a pc is a good thing.

FWIW:  I have an 8120 and I use the stock cooler (with no complaints)...but I don't game and...if I did, I'd spned the money on an aftermarket fan/heatsink.  They don't cost a million dollars and the it's the cheapest insurance/protection for your system that you can ever buy.


You're paying for a "custom build" of a gaming system...I believe you should treat an important component like the heatsink/fan...as it should be treated.  The cost is far less than any of the other components you listed...and those componenets won't do you much good if your gaming overheats the system.
