Did I damage my cpu? i7 3770k

I was overclocking my i7 3770k when I booted with too high of voltages. I'm not completely sure what the exact values were but when I rebooted I received a cpu overvoltage error and I could hear my cpu very loudly. After fixing the voltage setting by resetting the bios to default, I noticed my 3770k was clocked at 3.4 instead of 3.5 stock. The cpu seems to be running slightly warmer than normal with my hyper 212 evo cooler as well. I am getting around 35-40c idle and 60c-70c under load. I also get around 65c while heavy gaming. The temps were similar beforehand but these seem to be slightly higher.

What are the chances I damaged my cpu with overvolting? It literally lasted 30 seconds before I could set to default again.


thanks for the help.

Doubtful that you have damaged the cpu. They are pretty well protected by the internal PLL overvoltage unless you disabled that in bios. As far as "hearing" the cpu, I suspect you are hearing a fan. If the noise is still present, take the side cover off and if you cannot locate the sound easily, roll up a couple pieces of paper into a tube (or use the cardboard tube out of a roll of paper towels), and use that to localize the sound. Your temps are still fine, but I would suggest running intel burn test or prime95 and monitoring the temps with cpuz or the like just to make sure.

I meant to put cpu fan, sorry it was a typo lol. I have ran prime 95 and I am getting around 60-70c with a 4.2 ghz overlock. It usually hovers around 62-63 but will sometimes go up on p95. are these temps normal? And thank you, its very reassuring to know it is unlikely i damaged it. Are these temps normal? My main concern was in gaming it will usually hover around 40-50 but occasionally reach the mid 60s. That may be due to poor airflow in my case and my graphics card heat causing the cpu to heat up?
 


IMO, you're fine. The temps are certainly within reason. If you are worried about airflow, get rid of all the little dust bunnies, clean the fans/filters, rearrange your cables, etc.

Thanks for your help mark. It may be worth noting that I currently only have one fan on my cpu cooler in pull configuration. I will probably invest in a h100 soon. I'm not really used to temps being this high. My last cpu was much cooler. Never seen above 45c on my last one.
 


It's not unusual for Ivy Bridge cpus to run hotter than Sandy Bridge. Intel moved away from soldered on lids to thermal paste on the Ivies and increased temps are common, especially on o/c. If you don't have an exhaust fan on the back of your rig, try swapping your cpu fan to push - pull the cooler air from the front and push it out the back.

Take a look at the Swiftech h220 for water. Lots of reviews on it.
