I've just upgraded to a Core i5 2500K running on an Asus P8Z68-V PRO motherboard with 8GB of Corsair Red Vengeance RAM. This is the stuff if you need to look:
Asus P8Z68-V PRO Z68 Socket 1155 8 Channel HD Audio ATX Motherboard
Intel Core i5 2500K 3.3GHz Socket 1155 6MB Cache Retail Boxed Processor
Corsair 8GB (2X4GB) DDR3 1600Mhz Red Vengeance Memory Kit CL9 (9-9-9-24) 1.5V
I'm using the stock HSF that came with my retail CPU. The system is currently running on 'Asus Optimal Mode' as opposed to the standard or power saving modes that can be selected via the BIOS. I haven't had any lock-ups or restarts yet, though until my GTX 560 Ti arrives I haven't done any serious gaming yet. Does anyone know if it's safe to be running the 'Optimal Mode' on a stock cooling solution, or should I stick it back down to standard until I get around to buying a better HSF?
