Just overclocked my 4670k about three days ago, the most stable I had was at 4.4Ghz. But from what I see here, I'm wondering how my cpu is handling the overclock in stock cooling. I don't go over 65-70 degrees in load too. Am I dreaming or what?

Stock coolers are not fit for overclocking. They are barely adequate for stock. To check temperatures, I would say, realtemp is the most accurate. I definitely would use another software to confirm temperature readings. Or maybe you have really cold ambient?

I have a feeling that the overclock either isn't enabled or your temp software is messed up.

Here are some decent options in both Air and Liquid:

Get a h80i or similar - even wif t very best chips, a stock cooler is neither advisable or intended for OCing. And wig t aftermarket cooler u will probably find yo chip can go faster - yo max Vcore is I would recommend 1.3v so u hav plenty of headroom...

Yeah I know I need an aftermarket cooler for my chip's health. I'm just wondering why my temps are still a lot low compared to others in this o'c frequency. Or maybe I should just decrease the frequency for my chip's health until I can install a new cooler?

Can look in CPU-Z, CPU tab, lower left next to multiplier, it should show like 8-44 if a 4.4 OC is in...might have a really good CPU, might also be it's not a heavy load

That's certainly interesting. I'm in a good position to make a comment on this particular thread, I just switched out my stock Intel cooler for my CM Hyper 212 Evo. I use Aida64 Extreme for stress testing my system and monitoring temps (conveniently Aida has a CPU monitor app for my Logitech G510s keyboard!).

I was OC'ed to 4GHz with the stock cooler, and while stress testing my temps would reach low-mid 70s. Temps were fine while gaming, never went above high 50s. So today, I decided to redo my cable management and install my 212 Evo since I found my missing bolt. All went well, and I'm now OC'ed to 4.4GHz. My temps never go above mid 60s with that cooler installed, I'm also assuming my CM HAF X case is doing a good job with all of it's fans.

I would recommend using Aida64 to double check that your temp readings are fine, it has very detailed statistics including core speed, min/max/average temps for each core, etc. If you do use it, click on "tools" at the top and select Aida64 CPUID, it'll let you know if your CPU is actually OC'ed.
