Is this a safe overclock?

[AllHokage]

I just overclocked my i7 4790K CPU to 4.6ghz from the stock 4ghz and was wondering is this a safe overclock for my setup. Thanks

Also would it be safe to lower my fan curve a little?

 

Specs

CPU: i7 4790K
Cooler: Corsair H105 with Notcua NF-F12 2000rpm fans
Case Fans: 4x Be Quiet Silent Wings 2 1500rpm fans

Stock @4ghz
Room temperature: 22-24c
Idle: 30-35c

Aida64 100% CPU load (5 minutes): 60c 

 

Overclock @4.6ghz
Room temperature: 22-24c
Idle: 35-40c

Auda64 100% CPU load (10 minutes): 70-75c

What's your voltage? Should be fine, just stress test it and check for instability. If there is none, you should be fine (those temps are good). If there is instability just keep moving your voltage around and don't go over 1.35 generally.

I just went in my bios and selected 4.6ghz, Gigabyte has a auto overclock section in the bios. CPUID is saying the voltages set to 1.392V.

Should I try doing the overclock manually?

Yes, try to do it manually. Auto overclocking utilities tend to go a bit overboard with the voltage...

Yea, you should be fine, though as guys mentioned all those auto-overclockers usually give too much voltage. Generally what you're looking for is:

1. your frequency to be as high as possible running stable 30min stress test (10min is not enough, this is roughly a point where it stabilizes in some instances)

2. Having voltage under 1,4v. Above 1.4v will impact longevity of your cpu (but only a bit), ideally you want under 1.35-1.38v

3. Having temps under 78c, ideally under 75c.

4. If your thermal paste wasnt changed for 1 year or longer then I would re-apply a new one before overclocking. Ones from BeQuiet (DC1) or from Arctic (MX-4) are good and affordable pastes
