Good Heatsink for Overclocking

I have AMD A10 7870k. running on 4,5 Ghz. but i'm still using the original heatsink. i'm planned to buy a better heatsink. is there any good heatsink out there that can cool my CPU? or i just stick with the original?
The CPU temp maxed at 72 Celcius but usually only 40ish

More about good heatsink overclocking
  1. They're quite good temps for a 0.5GHz OC. I wouldn't worry.
  2. It maxes out at 72c because that is TJ Max for that cpu, the point when it starts to throttle lowering clock speeds to keep itself cool, thus hurting performance. I would turn off your overclock until you get a cooler, your pc will likely perfom better if that cpu is indeed throttling because of extra heat from your overclock. What would be your budget for a cooler? A cheap cryorig h7 or cooler master 212 evo would be fine.

    It would be for an intel cpu, not that amd apu. The OP is likely throttling at those temps.
  4. Yeah good point Dunlop

    what do you mean by throttling? am i giving too much pressure to the CPU?
    i tried overclocking because there is an official website in my country that stated the original hfs is good for OC
    i bought APU to minimize my budget actually. lol
    My budget for hfs is about 30$-40$

    so it means that i wouldn't nlow my CPU right
  7. No the max temp for that CPU is 72c. When it hits that the CPU slows itself down to avoid getting hotter. Thats the simple explanation.

    thank you, sir. that's a relief
  9. Well not really. Running a CPU at its max temp for too long wont do it much good. I would reduce your OC a bit until it stops throttling I think.
  10. Yeah pretty much. When the cpu hits 72c its designed to lower its clock speeds to stay cool, so if you're cpu is running at 4.5ghz it will lower the speed to say 3.5ghz or whatever it sees fit to keep the cpu at or below 72c.
  11. 72c is the max , they tend to not throttle till around 80c though generally.
    I'd replace the stock heatsink personally (unless its the newer wraith cooler you have ??), a $20 deepcool gammaxx 300 or s40 will do the job admirably , is a quick 2 minute fit solution using the stock mounts & has paste pre-applied

    You'll be mid 50s maxed out with either of those & a fair bit quieter.

    what do you mean with newer wraith cooler. i bought the processor some weeks ago. is the hfs counted as the new one?
  13. Yes its the new one you already have then mate.
    At 4.5ghz you are probably about at the limits of what it can manage under heavy load.

    How have you read temps ?
    Aftermarket monitoring software is notoriously unreliable on fm2 chipsets.
    Download amd overdrive & use the thermal margin under CPU status to accurately check your idle & load temps.

    In practice under a stress test as long as that thermal margin stays above 0c you are within an acceptable range.

    i read the temp using hwmonitor.

    but recently. my PC running normaly for some times. but when i started game, AC Syndicate to be precised, my PC shutted down suddently on its own. just like phew, and it's off
  15. Then you likely have an unstable overclock mate, probably down to too little voktage or quite simply too heavy an overclock.

    Without details of exactly what steps you took to overclock its impossible to ascertain.
