Hello guys.
I recently bought a 4790k and have been having overheating issues.
The mobo is Asus z97-pro, cooled by Zalman cnps 11x performa+. Thermal paste Artic MX-4.
Mobo bios updated to latest version.
Case Corsair Carbide r300 with 2x140mm in front and 1x120mm on the back.

Room temperature around 20 degrees, so inside the case probably 20-25 degrees (celsius, Im brazilian).
All temperatures of the cpu I post here were measured with realtemp.

Using the auto configuration of the mobo, it automatically overclocked all cores to 4.4ghz, vcore 1,22v.
In prime95 28.7, temperature quickly raised to 100 degrees.
At this point I stopped the test.

After that, I manually set my mobo to a 40x maximum multiplier, limiting the cpu clock to 4ghz. Asus then automatically disabled turbo boost.
During tests, the maximum vcore i see is 1.08v now.
In prime 95 28.7, maximum temperature is 76 degrees after 10 minutes.
In prime95 26.6, maximum temperature is 65 degrees after 10 minutes.

My conclusion is that I can run it safely at 4ghz.

However, is there a magic bios configuration I could set to allow me use turbo boost at 4.4ghz?
Or I would need a watercooler for that?
Or by any chance i got a bad cpu?

Also keep in mind i live in Brazil and temperatures can reach 40 degrees in summer, although i usually turn my ac on in these cases.

Thanks very much in advance

Anything that gets it 100C quickly on whatever cooler is unsafe. Before you change your cooler, find out what your existing one will do, and perhaps what your chip is capable of. Then you can choose what is best. Unless there are space issues or you transport your system a lot, I would choose air over the h80i.

You may still have a below-average CPU; one that needs a lot of voltage to achieve a modest overclock, but that's another story.

Set it back to stock and run Prime95 26.6 When overclocking, I like to use OCCT for a stress test. If it passes about ten minutes of that, I assume it is stable and move on. Only when I get to that limit, do I do a full stress test for final stability.
