overclocking 4670k on stock heatsink

[kees123]

everywhere I'm looking all I can see is that ''the stock heatsink can barely handle stock clock speeds''
and people hitting mid 70s on minor overclocks like 4ghz.

Now, on 4 ghz my 4670k with stock cooler maxes out at 55 degrees on prime95.
what is up with that?
is everyone just exaggerating how bad the stock cooler is?

how long you have run the prime 95 run at least 30 min ...

More information please.

Which Prime95 test? There are three tests, and it makes a difference.

What is your ambient temperature?

What temperature monitoring utility are you using?

I've ran the blend test for about an hour.
Ambient temperature is about 22 degrees celsius and for temprature monitoring I'm using both speccy and realtemp.

Blend is a cyclic workload with fluctuating temperatures, which will show differing values during it's cycles. Good for testing memory stability, but not useful for CPU thermal testing.

Small FFT's is used for CPU thermal testing because it's a steady-state 100% workload:

No they are right , you shouldn't overclock on the cheap intel stock HSF.
