Intel i7 4790 question

[magocbi]

I recently build my first pc and i was using OCCT to test my cpu temp while on load and it said that the clock was at 4.1 but it should be 3.6 no? I'm very new to this so I'm confused.

The max turbo frequency for that CPU is 4 GHz.

thanks, also is 70C ok while doin the load test?

Yes, are you using the stock fan?

How long did you run the load for? 70 seems a bit warm in my opinion.

When you installed the fan, did you make sure that the little bolt which sits on the bottom of the fan, above the processor, was straight and not crooked? Getting it straight took me about 30 minutes of trial and error before I finally got it. Assuming this was your first time installing thermal paste, how much did you use? My first time I put way too much, you want to use a very small amount, about the size of a grain of rice.

I would suggest running the stress test for a couple of hours and see the max temp. Anything under 75 degrees is what I would be comfortable with.

It may be worth it to reinstall everything if you are having any doubts about the installation, although this is a tedious process so I would probably just stress test it first to make sure it sits at a comfortable temperature.

im testing right now and it seems between 65-72

 

[magocbi]

it took me quite a while to mount it but i think its mounted correctly. I might of put a bit more of thermal paste than i should of i guess

About 70°C is fine, but if you want to cut down the temps, then disable turbo boost. An easy way to do that within Windows: control panel, system and security, power options, change plan settings, change advanced power settings, processor power management, maximum processor state, change to 99%. That also reduces voltage, resulting in lower temps. Doing this will force your CPU to run at its default 3.6 GHz clock under load.

I think his fan is not installed properly, or there is an airflow problem. I have the "k" version of your processor, as well as same cooler and paste... I hit 50 degrees under load when I was under clocked at 4ghz. I have the fan running at full RPM, but that shouldn't be much of a problem.

Try going in your bios and changing the fan speed to "performance" or "full speed." You can toggle this under CPU FAN1. If that doesn't work, make sure you have it installed properly. Ex, the nuts that hold the CPU back plate are in all the way. Replace the thermal paste with a very small amount, the size of a grain of rice. It can't hurt to at least check and replace your paste. Will only take 5 minutes to do that.

Besides that, I'd say you're golden. Your fan probably isn't running at full speed like mine so that's probably why the temperatures are higher, but anything below 75-70 is acceptable to most people. If that seems too high to you then raise your fan speed in BIOS.

I did this multiple times when I first replaced my paste. If you see sticking up on the sides, you definitely put too much. A small amount goes a long way. Remember, you are only using that paste to remove the barrier between the heat sink and CPU... If you put too much, it defeats the purpose.

Consider yourself lucky. My i74790k and both game in the 80`s...

Is your fan running full speed? Are you overclocking? Overclocked at 4.6ghz my max temp is 76 degrees. I have pretty good air flow in my case.

When I used the Intel heatsink/fan, I was getting 90 degrees +.

You have the Hyper 212 Evo?

He cannot OC his CPU since it's a non-K model. My temps max out at about 63°C while running at over 75% load (1-minute sustained). And that's on a Hyper TX3 fan with turbo boost disabled and no OC. With turbo enabled and CPU running at 4.4 GHz, I max out at about 77°C. My CPU fan is not as effective as the Hyper 212 EVO, but it's a heck of a lot better than the stock Intel cooler. Try disabling the boost feature and see where that gets you.

Oh, well you could have quoted that post to avoid confusion.

One has a H100i in it , and the other I am waiting on a NH-u12s cooler. Hoping the NH-u12's and some setting tweaking with the h100i will reduce the temps.
