What are the temps like though? I doubt a 5.3ghz oc on air will stay very cool...

Since there's absolutely no way Intel has designed a chip that breaks the laws of physics, something changes as the temperature changes. While reviews have shown that temperature is not affecting overclocks much, I believe it is because the CPU is auto-regulating the voltage down as temperature decreases. Effectively, the overclock stability will remain the same despite temperature, however the voltage (and power usage) will be lowered with temperature.

How does this affect your overclock? It means that higher voltages are safer the cooler the chip is.

This is an example of temps of a 2600k with a H70 for cooling. This in the folding section. For running 24/7 @ 5Ghz plus @ 100% it looks like you need really good cooling.

Digigami is the OP
This is with vcore set to 1.375 in bios, cpuz reporting 1.392, temps are starting to get warm here, average 75 and high of 78 folding. For now this is the highest I'll be testing at. I seem to be stable folding at 5.0 and 5.1 for very short runs, but temps start to climb real fast. I did not let it run long enough to get any frame times.

The jump from 4.9 to 5.0 and beyond looks like it takes much more vcore on my chip. I could not boot windows with any less than 1.450 set in bios, idle temps still really great 30`c and up to 80% load kept temps acceptable around 70`c.

Just look for Linus Sebastion on NCIX Tech Tips.

On his youtube channel he releases the latest news every saturday

lol. if your new sb chip isnt breaking over 80c then your not trying hard enough.

Guys, we don't know how much cooling the new SB needs until we have some overclockers give us confirmed benchmarks.
