H75 - is it really this bad?

[Cheddle]

running a 4690k at 4.5ghz, takes 1.31v to keep it stable. playing games its about 50-60 degrees and inaudible but if I run a stress test like Linx or certain AIDA64 tests it rockets to 90+ degrees and as such the cooler fan runs at 100%...

 

Is this normal with this cooler? whats the limiting factor here? I feel like there isn't enough heat being dissipated from the chip to the cold plate - it seems like it instantly rockets in temps.

That would be Haswell's FIVR rearing its rather ugly downside-increased heat output.

Sounds like a a dodgy thermal paste or thermal paste application. Not sure though.

Its no better (and often worse) than a standard air cooler, however those temps are fine for games, honestly I would ignore stress tests, its VERY rare your CPU will be pinned under loads that high for long periods

 

the only way to increase cooling would be airflow, and the size of the rad etc

You're not on adaptive voltage, right? Your temps are abnormal.

I have a 4670K overclocked to 4.6ghz, 1.325 volts on my H90, which is a 140mm vs your 120. I see temps of about 70C when it's maxed in Aida, so your approx 30% smaller cooler is pretty close to what I'm seeing, honestly.
