i5 daily overclocks?

so currently i am running an i5 2500k overclocked at 4.6ghz and with my coolermaster v8 while running prime95 i never get above about 60C on any of the cores. for a time just to benchmark i overclocked to 5ghz and was stable for atleast the benchmarking. i soon reverted back to 4.6ghz again because that just seemed like a really high frequency to be at... anyways, i was just wondering what other people with 2500k (or even 3570k) have their cpu's overclocked to and what temps they are reaching with what cooler (also at what voltages?). 

*i am talking the overclock you use for a day to day situation although i am also interested in how far you have pushed it just to bench*

 

 

 

 

My friends pc with a custom loop runs at 5.2ghz at about 55degrees. If it doesnt get that hot, and your not past bad voltages, no reason to worry how far you go.
