You have lots of headroom temperature-wise if you are in the 50's. What is your voltage now?

I would say that as long as you temps are in range 65-70 for warmest core at 100% load (crunch) you should be safe. And voltages under 1.4 should be no problem (although at 1.4V your temps will probably sky rocket) so I have read that up to 1.38V the temps should be controllabe, especially as you have a water cooler.

My cpu is running at 1.37V and the warmest core during crunch gets to about 70C which I have set as a 24/7 safe limit (even though intel thermal sensors are Not to be trusted), but then again it produces a LOT of heat with its 6 cores and massive 12MB cache. At stock settings it has a TDP of 130W (meaning the cooler should at minimum be able to transport that amount of heat), an overclocked I belileve that value is closer to 200W. The cooler I use is the Corsair H100.

Good news is that it is said that at least the more premium boards will be compatible with Ivy Bridge-E so the board gets a longer life span only having to change the CPU (if it will give significant increase in peformance over SB-E).

Changing the voltage is not dangerous if you stay within limits and more often you will reach too high temperatures before the voltage gets too high. Remember that even the same CPU model has different stock voltage for each individual chip, since each chip is unique in quality and therefore requires more or less stock voltage.

Keep up the good work guys =)

Gotten myself a cheap laptop for work whit a Core i3-2330M, works out better than expected for crunching i gotta say. Got it running around the clock, one more small output boost

Well the house plan fell through...
Maybe that motherboard is a possibility...

Morning Cober,
Crunching away,
as are our footsteps in the new falling snow.

350W is without monitor and GPU in idle (Radeon HD4850@stock).

But just for interest of it, a comparison:
2600k with iGPU @ 4.4GHz (8 threads) => >25W/thread @ 100% Load
3930K with HD4850 GPU @ 4.53GHz (12 threads) => ~29W/thread 100% Load

So it is not too far away, but then one has to remember that more power is drawn not only from a more cores, but also more cahce and Quad channel memory controller. And if it would have a more modern gpu (or integrated) then consumption should be lower.
