High temps?

[King_Gamma]

I just got a 4790k and put my Cryorig R1 ultimate. While running the stock clock I am getting 70° C on prime 95. I am using HWMonitor for the readings.

I feel like this high. Any suggestions or is this normal?

[flibberdipper]

Don't use Prime95 on Haswell. It will make the voltage go nuts. Use OCCT or AIDA64.

I have tried using them and I get even higher temps.

Really? What voltage is it at when you have it at full load?

I couldn't tell you that at the moment. I haven't messed with the voltage so it is stock on the MSI z97 gaming 5 MoBo.

The strange is that I am getting nice low temps on idle at like 27° C but load is a different story.

Use CPU-Z to monitor the voltage while stress testing the CPU.

The voltage in the BIOS could be set on 'auto' in which case the voltage will fluctuate depending on the load. Try setting the voltage in the BIOS yourself.

 

If that doesn't help then make sure the cooler is installed properly, re-apply the thermal paste if you need to, and clear up any dust inside your case if there is any.

Remount the cooler because I get a stress test temp of 75C at 4.5Ghz and a idle of 28C (25C ambiant) and I use both a NH-D14(summer) and a Kraken x60(winter)

I do know that the voltage does fluctuate. What would be a good voltage setting for my CPU?

I have remounted it. Is it possible that I put too much thermal grease on?

Very much so only use as much as an uncocked grain of rice

If you running at stock your voltage should be less than 1.1V imo.

If you are running OC then try to keep your voltage enough bellow 1.4V. 

I believe the stock voltage is 1.15V, but from my experience you can easily go lower than that if you are running at stock clocks.

OK well I'll remount it again when I get a chance.

I am also concerned that it isn't getting enough airflow because of my case which is the nzxt h440.

OK I will look into that before I remount the cooler.

Why not use the D14 all year round?

[Zelx]

From my experience, if you have the case running on stock fans and stock RPM (on the fans) you will be getting a increase MAX of 7ºC. On stock clocks.

D-14 is to noisy and it actually sometimes gives a cold bug due to it getting so cold in my room while the AIO I can leave my system on pretty much 24/7 during the winter and not have to worry about the noise keeping me up

So I should see mid 70s on the temp?

OK I am running at 1.24V and after 5 minutes on AIDA64 my highest temp is 71°C. How's that?

[Raudi_]

That is ideal, with the ventilation that the H440 has and lower would be AIO Water Cooling territory

I'm getting low 70s high 60s on AIDA64 and prime95. This is at 1.24V running 4.4 MGHz

How is that?

Thats much much better then before. What ever you did worked.

Sweet! What should I aim at on max temp wise on an over clock?

[Raudi_]

Sweet! What should I aim at on max temp wise on an over clock?

I say aim for a temp Max of 80C while stressing anything higher I say would be considered a failed overclock with those temps. But thats just me, the haswell CPU's throttle @100C

OK thanks! What would be better for testing Aida or prime?
