We made it all the way to 5. This didn't surprise us, given our experiences with Kaby Lake. Depending on the motherboard, different levels and presets are available, or the voltages can be manually adjusted for some experimentation.

In this way, the core voltage can be reduced significantly without losing a whole lot of performance so long as your chip plays along. For the motherboard we tested, the effective voltage was between 1. Unfortunately, many memory kits run into trouble if the load-line calibration is set too low; the result is general instability. CPU quality plays a key role as well. In our particular case, this affected our 5. All of the games and some of the workstation applications ran for hours without any problems, but Creo 3.

But remember that most of them aren't validated for long-term reliability. We'd rather drop the clock rate by MHz and not have to deal with intermittent crashes. Power use continues increasing with higher clock rates, but the Cinebench score levels off.

A failure to continue scaling at 5. It simply cannot dissipate heat quickly enough. At idle, the differences in power consumption are fairly marginal. All of the processors end up just about where we'd expect based on previous reviews.

AMD's Ryzen processors draw significantly more power than the Intel competition because their idle clock rate is a bit too high. The finishing order changes dramatically once we fire up an AVX stress test with all cores running at their top Turbo Boost bins.

During rendering, we were seeing the K's stock power consumption at W, climbing to W under a 5 GHz overclock. AVX without offset pushes the result as high as W.

The Core iK at 4. And that's in spite of our compressor cooler's efforts! Thermal paste under the IHS does us no favors. The above graph shows that a closed-loop liquid cooler is able to keep an overclocked Core iK from throttling after 20 minutes of warming up. A good heat sink and fan combination should perform almost as well, again, given ample airflow.

Under our stress test, the overclocked processor gets uncomfortably hot, even under our compressor cooler.

See screenshot here:. Nov 20, 0 0. What's your ambient temp when it's idling at 40? The K is known to have heat issues in some situations, but I can't say about yours with an NH-D15 at that clock speed and voltage. There's certainly nothing wrong with 40 idle for eternity. May 24, 6, You should be able to hit 4.

I have a 4. My idle is C, although during gaming it will hit around 65C. Your load temps are fine but idle is a little high for a Noctua D In fact even on the Intel stock cooler I idle around 33C. It may be voltage related or it could be high ambient temps. ShintaiDK Lifer. Apr 22, 20, Its completely normal depending on cooling and fan control.Tech Guided is supported by its readers.

And, there is really not a one-size-fits-all approach to determing normal CPU temperature ranges. If you are looking for a quick answer, we have attempted to give you a one-size-fits-all answer below. But, just know that it will never be a great way to determine whether or not your CPU temps are too high or not.

Again, there is no way to give you an accurate one-size-fits-all answer to whether or not your CPU temperatures are too high or not. So, in other words, if your CPU is hitting those temperatures on a regular basis, you will likely want to dive into the problem further and see what is going on.

Again, this is a generalization. And, the temperature shown in your BIOS will always be a bit higher reading than what it will be when the system is idling in Windows, because BIOS will always boot your processor using higher voltage levels in order to make sure that it will initialize.

There are quite a few different programs out there that will let you monitor your CPU temperatures and some will monitor the temperature on your other components, too.

Core Temp shows you what the individual temperature is on each one of those six-cores. To check what my temperature is under a heavier load, you could play a demanding game like PUBG, or Battlefield 1or render a video, or do something else taxing.

There are a number of stress-test tools out there and there is a lot of discussion on which one is the best to use. The SmallFFT test on newer versions of Prime95 will actually push your processor past realistic levels and, therefore, is not a great method to use if you are trying to determine whether or not your CPU temps are safe or not. But, the general consensus is that Prime95 v.

So, now that I have those numbers, how do I know if degrees Celsius while idling and degrees Celsius under full load is a good range of CPU temperatures for my processor? While I can tell you that those are generally safe CPU temperatures for the K at stock settings and with the cooler I havethere are a few things that I had to consider first before declaring that those are CPU temperatures I can live with. Once you have those temperatures, then you can seek out whether or not they are normal.

And, if a CPU manufacturer suggested a one-size-fits-all recommended operating temperature, it would likely cause more harm than good. Now, Intel does provide a maximum operating temperature, which we will get into in just a moment. And, if you have an Intel processor, that maximum operating temperature will help you determine whether or not your temperatures are approaching or hitting a level that is definitely too high.

An Intel Core iK is going to run at different temperatures than an older Intel Core i at idle and when under load. The older iQM processor in my laptop is going to run at different temperatures than a desktop processor, or than a newer Intel Core iH laptop CPU. Most processors run at different temperatures, whether by slightly differing amounts, or by significant temperature differences.

The next thing you need to consider is ambient temperature or room temperature. But, why is my processor running 3-degrees Celsisus higher than theirs? And, that difference in room temperature is why your processor is running at a higher temperature than the benchmarked processor.

So, before you freak out, make sure you take into account the room temperature your computer is operating in and factor that in. It may just be that that person has their computer in a much cooler room than yours. But there are definitely others who will prefer rooms much cooler or warmer, depending on their preferences.

In any case, ambient temperature or room temperature is an incredibly important factor to consider when trying to determine whether or not your CPU temps are too high. Of course, you could be getting higher or lower CPU temperatures than others for a few other reasons, too.Log in or Sign up. Overclockers UK Forums.

Jul 17, at PM Jul 18, at AM That is a good result and different to what you had got before. What is your LLC and vcore set to in your bios? What has helped to give a pretty solid fluctuation free vcore for me has been to not bother with an offset. I have dialled in 1. Even tho it will use that voltage constantly the CPU will still drop to mhz when idling.

The vcore has been super steady, much more so than when using an offset. Jul 18, at PM Will benchmark some games over the weekend and report back. Danny75 Sgarrista Joined: Aug 26, Posts: 8, Pity as it's pretty useful for maintaining higher frequencies during non-AVX operations.

Idle is fine as in ambient is 25 and the CPU package is This is with the fans on full speed manual control and reapplied MX4 paste. Thermal Throttling occurs and this is at stock speeds!

Not even started to try overclocking. The cooler is fitting fine. Same results with all of them. I have an H75 and G12 to watercool the gfx soon anyway I've disabled the Asus Multicore Enhancement, played around with the core voltage with offsets etc, LLC's and tried even underclocking it to 4.

I've also tried swapping out the RAM and running just 16gb with the same results. I'm at a loss as to where the problem is. I've updated the BIOS, loaded defaults, turned off turbo etc and still the temps are crazy high. I've read that these chips should be happy enough 4. Will try fitting my H75 on it tomorrow but being smaller I'm not expecting any improvement.

Just wondered if anyone had any other thoughts on this situation before I scream and send all the parts back for RMA. Thanks in advance. Dec 10, at AM 2. Is the CPU cooler set as intake or exhaust?

Not that it should make things this bad without GPU load. Is the radiator getting warm? I doubt it's a dead pump as you're saying idle temps are ok, but you didn't mention a speed readout. Dec 10, at AM 3. Thanks for replying. Rad is an exhaust at the top. Radiator gets only slightly warm only at the point where the intake pipe meets the radiator. Its brand new so I'd hope it's not the aio that's dead. Touching the side of the rad it doesn't feel hot at all.

When I had it on the aio header on the board it showed rpm for the pump.

Forgot to mention when running prime even though the temps are within ''limits" it'll hard lock the pc after a few minutes.

But when I started playing I noticed after some time that my frame rate dropped from having fps in csgo down to like That's not good. Turned all the fans to max rmp so it's better but still very high.

I noticed that my voltages are high while I was trying to figure our what's the issue. I'm getting roughly 1. What the hell? I checked online and I should be getting around 1.

Tried to lower Load line calibration In bios but I wouldn't let me so I found it in a motherboard software app that let me change it from high to medium or sth like that It wasn't really precise.

Didnt help though 3. So my question is: is it motherboards fault for giving too high voltage?

Core i7-8700K Review: Coffee Lake Brews A Great Gaming CPU

SDero Customer asked a question. So, I have two thoughts. First, yea, these seem high for a liquid cooling solution. Second, the idle temperatures are only concerning is the loaded temperatures are similarly high. If you aren't reaching 85c under heavy load, then I wouldn't worry as much.
