known for having loose heatsink connections? Is there a way to tighten the connections up at all?
Anyway, temperatures are down in the low 30s celsius now. Should I even worry about Speedstep not kicking in, now that I seem to be at a reasonable temperature even at high frequencies (as long as the heatsink is actually seated correctly)? Also, should I trust CPU-Z's constant 3600 MHz frequency reading or RealTemp's ~2780 MHz reading?
Wait, were you doing a 4.0 ghz OC with stock cooler? Arent those stock coolers only rated to handle a CPU clocked at stock voltage/clock under load? Your temps look pretty high; to be honest id want to stay at 70C or under if you can? Have you considered saving a couple bucks and getting a cheap CPU Air cooler? (assuming you dont want to go AIO liquid cool)... a simple 25 dollar cooler will drop your temps by a lot compared to the stock fan.
In addition, you can buy better thermal paste, maybe that will drop your temps by a couple C? Speedstep drops you down to 1.6 (from what ive seen) with the i5-2500k, but dropping to 800 mhz sounds like news to me... haha
I just suggest buying a different alternative cooler, honestly youll spend 20-25 on a cooler, but save the life of your i5-2500k (which costs 219)
