H80i sucks, new cooler?

[rtho782]

With my 4790k, at stock speeds but set so turbo will hit 4.4ghz on all cores, my h80i can just about cope.

The water temp doesn't even hit 40 degrees Celsius according to link, yet the CPU can get as high as 90 according to core temp when running Linx Linpack. It just doesn't take heat away from the chip very well. I've remounted it several times, and fitted spacers to the back of the mounting bracket so that it isn't loose before I apply the block. No help.

I can actually hit 5.0ghz and boot to windows. It doesn't crash at this speed, but under load it thermal throttles.

I want to be able to actually run at 5ghz. What do I need, cooling wise?

Doesn't matter about water temp, that makes little to no difference to CPU temp.

They're not that awesome performing as it's a 120mm AIO, and you've got a 4790k. Just a bad match up IMO, I'd have at least a 240mm AIO or custom loop on it.

You're not checking the avx box are you? That will roast a Haswell

Is avx auto vcore? - if so then yes, not a good idea. I set mine to 4.6ghz but forgot to set manual vcire and at load it decided to wack it to 1.4 something volts.

Good luck getting it stable at 5ghz, especially with something like realbench

I ran my 4790k @ 4.6Ghz with a H60 so a H80i should be plenty fine. As above, I suspect your voltages are too high
