Over clock 4770k with stock fan using asus bios settings z87-a motherboard

Over Clock with my i7 4770k.

My system

i7 4770k 3.5 ghz (stock) 4.2 ghz (current) voltage peaks at 1.230 volts
PSU HX1050 gold
Asus Z87-A 1150 socket
SLI 780ti GPU (2 cards)
  1.  

16 GB 1866 ram
3 SATA 2TB drvies
1 SSD 150 GB Drive

I recently used the over clock utility in my BIOS to run the system on Performance Mode, I just used the default setting that the motherboard had to run the oc. I have a stock cooler on the cpu and the temp seems to cap out at 68-72c and when the prime95 stress test runs it caps at 99.8 c , the voltage caps out at 1.230 total at max. Is this a safe over clock or am I hurting my computer with this set up? I first used this in February and the computer has run issue free so I don't think its hurting it but I'd like to be sure.

it's not reccomended...
you would not want your 4770k runningat 100c frequently.

with that being said, thats only in a stress test. your real world 70c is ok and it will be fine.

silly question for you... you've spent alot of money on your computer... why not get a hyper 212 evo for $30? or a cooler master 120 liquid kit for $50? both are very small investments compared to your very high end components

I was told by the people at the store that the stock fan would be all I needed running at stock speeds.

That is true... but you are no longer running at stock speeds... So you should get an after market CPU cooler. The hyper 212 evo is a nice cooler if you want to stay on the cheap side, one of the best air coolers is the NH-D14 (about 5c lower temps vs evo) but it costs around $75 vs the ~$35 for the Hyper 212 evo.

In that case have I done serious damage to my system? Like I said it seems to only reach 72 at peak when playing high end games. I hope I haven't done really serious damage

The people at the store are correct:

1. The stock cooler is all you **need** to run programs, games etc.

2. Prime 95 is not a program, it serves no use whatsoever other than to put unrealistic loads on your CPU. It's not recommended for Haswell CPUs except under manual voltage control due to the presence of AVX instructions which can spike voltages.

3. They told you it would be all your need running at stock speeds but you are not running at stock speeds.

On a side note, the HX850 (10.0 performance rating) would have been fine for your needs and is much better PSU for overclocking, the HX1050 (8.5 performance rating) has some issues, notably voltage regulation and ripple suppression, so it may limit your OC a bit

A short stint at 99C won't cause immediate damage to the CPU but continued hi heat and / or voltage will reduce its longevity

I doubt you have done any serious damage to your system, I'd put the CPU back to stock till you have a better cooler in place though.

For that I simply need to go back to the BIOS and select "Normal" Under System performance and it should put itself pack to normal?

Best to "Set BIOS to defaults"

Thanks guys! I feel pretty stupid for what I did but I think I can change it back and all should be well until I get money for a better cooler. Thanks again guys and thanks for being nice despite my hardcore noob move :)
