AMD FX-6300 OC to 4.0Ghz, using aftermarket cooler and arctic silver 5(applied as recommended). Original temps during idle were 33-35C but during the last week the idle temp rose to roughly 40C(which I am not concerned about) and the temp under load(which is my concern) rose to 54C under 25% load when previously only reached that temp under heavy load(like running Fallout 4, not stress testing). Is this normal/expected?

Edit: Corrected CPU model.

Honestly mate just do 20minutes of prime with overdrive onscreen , anything above 10c thermal margin while its running is fine.

Just forget about it then if that thermal margin is fine.
Temps can be adversely affected by ambient temps etc - my system runs 10c hotter in the evenings when the heating is on etc.

What board are you running on ?? 4ghz is a relatively small overclock, you could probably drop voltage a bit , also if you've disabled cool & quiet for any reason (a lot of people do) then re-enable it ,there's no reason whatsoever to have it disabled ,it'll keep full voltage & clocks at idle it low load when disabled & will adversely affect both idle & load temps.

Do you mean FX 6300 ? Which program do you use to measure temps ?
If those numbers are accurate and temperatures are by core, staying under 60c per core is tolerable and under or about 55c very good. If that's under load for prolonged time of course, idle temps you can disregard as they are not accurate on those processor.
Best to use http://www.amd.com/en-us/innovations/software-technologies/technologies-gaming/over-drive for accuracy.

@CountMike Thanks for the reply. Yes, FX-6300. It was late for me and I went a wee bit dyslexic there I guess, hah.

Anyway I was using CPU-Z to monitor clock frequency and voltage to ensure those remained stable(they did), and SpeedFan for temperature measurements. Under heavy load(100% stress test) it seemed to maintain 60-61C so I'm not really worried about it overheating, I was just concerned that the temps went up by about 10C overall since installing the CPU. A week ago they were all much lower and I don't know if that's something I should be concerned about.

I did install OverDrive and its temps read the same as SpeedFan.

Yeah it all looks good in that case. Thanks for the advice. The board's an ASUS M5A97 LE R2.0. Overclocking past 4.0Ghz makes Win8.1 BSOD so I just left it there for now. The voltage is set to auto and CPU-Z reads it at 1.27-1.3v.

Yeah the turbo for it is 4.1Ghz so I could probably get away with that and the system would still be stable. By the way, re-enabling C&Q dropped the CPU temp by about 5C, so doesn't look like I've got anything to worry about at all. Thanks for the help!

No problem mate.
Bear in mind that that 4.1 turbo speed doesn't boost all cores , at 90% load it'll only boost 1 core, at 70% it may boost 2 or 3 while dropping clocks on the remaining ones to keep within that 95w tdp rating.
The way you have it is the way I would set any fx CPU up - you are far far better with a higher base clock & turbo disabled than stock speed with the turbo enabled

Yeah, I was checking around for answers elsewhere and saw that was the recommended setup by people who know a lot more about overclocking than I do. Turbo didn't seem to be doing a lot to give my PC much of an -actual- performance boost, and I didn't like the way my CPU freq was fluctuating an absurd amount. I can't possibly imagine that's good for the hardware. I'm glad I got things right without wrecking anything!

Not harmful to the hardware in any way mate - but those clock drops on odd cores with turbo running can play absolute havoc with performance in proper multi-threaded games & apps.
Never ever liked the turbo core idea - it works pretty well on Intel CPU's but not so much on amd - its more of a marketing / advertising ploy than anything else imo
