should i keep my overclock?

[cjcj11]

right now i am using an i5-3570k with an asrock extreme 4 z77 motherboard and my cooling is a hyper 212 evo. i used to have it overclocked using the preset overclocks in the bios at 4.4 ghz my temps never went above 70 degrees. i then followed a video on getting the overclock to 4.6 ghz and i am at that speed stable right now. on cinebench i get about 7.46 but on the flip side i get my top temps at about 83-84 degrees, and i use about 20 more watts with the overclock. at 4.4 i got around 7.2 on cinebench, is it worth it to keep this overclock or should i go back to the settings i had before? also i have to keep my target fan speed level at 5 compared to 1 and my target temperature is set to 50 degrees

What do you have for a cooler? I would go back to 4.4 if i was you, but if you can buy a better cooler then maybe itd be worth staying at 4.6

coolermaster hyper 212 evo as stated before, but it turned out the overclock wasnt stable, it actually held up pretty well and then after a while i was re-running cinebench and it crashed upon start
