I have a fx-6300 and my friend is going to be getting a 8350, however he is going to purchasing an aftermarket cooler with is. I plan on getting a water cooler, but for now I am running with the stock cooler, and no oc. I know that the 8350 cooler has to be better than mine due to the heatpipes and raw size increase that it has, I was wondering if it could keep my 6300 within reasonable temperatures with a slight overclock, something like locking it to the turbo core frequency.
Should be ok, i wouldnt go more than a few hundred mhz on stock cooler ever though. I would suggest grabbing a hyper 212 evo, awesome cooler for like 30 bucks, i always keep a few on hand for builds.
The stock cooler included with the FX-8350 is a little bigger then the one they put on the FX-6300 it also has some added heat pipes so there is that. My guess is you could get a 10-20% overclock if you used that on a 6300. Even without an overclock it should give you the thermal headroom that the CPU is always in turbo mode. That being said the stock cooler is very, VERY loud, and its thermal performance is . . . nothing short of terrible. Go with Cathsy idea if you can; a Cooler Master 212 is really good and they are only like 30-35$ USD.
If you just want to use the larger stock cooler as a upgrade; putting good thermal paste will make a good difference as well. Better thermal compound applied correctly could drop temps as much as 10C so keep that in mind.
Yea I am using the stock cooler, but I replaced the thermal paste with ac5, I just need the cooler to hold me over until I get that water cooler.
Depending on your ambient temps then year it'll be a decent upgrade until you get your new cooler. If the noise of the fan gives you the shits swap out the 70mm fan for a pwm 80mm or 92mm fan (zip tie or diy bracket).
