I overclocked the chip from 4.2 by 0.1 GHz increments. It started throttling at 4.9 so the maximum I reached was 4.8. I tested it with Prime95, AIDA64 and Crysis 3 for 5 minutes apiece (longer in Crysis 3).

It seemed stable. One crash occurred in Prime95 but this was the last test so the PC was already hot. I only changed the multiplier and left the voltage to the DIGI+ VRM on the motherboard.

Under Load
Max CPU temp: 52 C
Max Core temp: <105 C (avg 90-5)
Max VCore: <1.4 V (avg 1.336)
Throttling: 0% (4%+crash on 4.9 GHz)

When I first started this, I read of people only reaching 4.2 without changing Vcore, and 4.5 on air max. Should I be worried about these temperatures, or was I lucky in the silicon lottery?

Also, how many extra years have I got out of the CPU before considering upgrades, going from stock 3.4 to 4.8?

1.3v exactly is considered water only range. 4.8 on 1.3 isn't bad (Never want over 1.3 really.) but 90-95c is. You want to see ~80-85C max.

I don't really have space for water cooling. Should I lower the multiplier?

Just to clarify, I'm getting core temps of 50-60 C in Crysis 3 and 80=>90=>100 C in Prime. I can't think of any real world performance/games more demanding than Crysis 3. Is my CPU definitely in danger?

Not, in danger, but what is/are your gpu(s)? as my 290x isn't bottlenecked by my 3570k at 4ghz.

7970 GHz (Gigabyte Windforce)

I'm noticing a huge difference in day-to-day tasks as well, web browsing, text editing, etc.

I got it down to 4.3 GHz
Max V 1.280 (from 1.320)
Max T 82 C (from 90-100)
Avg T 70 - 75 C
57W (from 66+)

Lower than I hoped but I'll make do
