A few days ago I received my 4790k along with my Maximus VII Ranger motherboard. I've got them all installed now and am using a Be Quiet! Dark Rock 3 to cool the chip. However, after starting the PC up and playing around, I noticed the temperatures in HWiNFO64 are very strange.

Having come from AMD, where it was simply an easy to read table with one temperature, there are now many many temperatures for my CPU and so after running Prime95 and getting some fairly high numbers, I'm looking for clarification on what is normal. The chip is running at stock (4.4GHz boost).

Are these temperatures normal? When HWiNFO64 was reporting around 80 degrees on the CPU, AI Suite 3 was recording only 66 degrees on the CPU. I don't know which to believe and don't want to damage my CPU.

Cheers.

I personally prefer Real Temp over these, but Al suite is fine too. HWiNFo64, I really have no real idea about it.
yes those temps are OK.

The ideal temps are:
30-40C when idle.
40-50C when streaming/ browsing/ mild gaming
50-60C when heavy gaming/ video rendering
60-70C when gaming at ultra or rendering heavy files.
Its OK to get upto 70s in very high usage.

You should not get above 80C.
85-90+C and it starts throttling.
105C is the temp where CPU officially is unfit for use.
Advice: keep it under 75C at all times in general.

Hm okay I see. So even with this Dark Rock 3 them temps are normal? What is the highest core temp I should look for?

Also, which temperature should I believe? AI Suite or HWiNFO64?

Okay so I've looked around a bit and after you saying to keep it under 75 I feel something isn't right.

This is a screenshot of my BIOS settings:

Do they all look okay? The cores seem a lot lower than the cache, could the cache's high voltage be causing temperatures? Would it be worth reseating cooler? I bought this cooler for the fact that it has won gold awards, so for it to not be able to cool this chip even at stock is a disappointment.

Cheers

Well many other threads say to always keep the package under 72 degrees to avoid damage, yet mine is at 79 degrees. Seems very odd. I'll keep an eye on it, the paste etc may need to settle down.

I think we're on different tracks. The last image you posted is showing 34C which is a very fine temp.
Yes its recommended to keep CPU under 72C. It DOES NOT meant if we reach there, the CPU is damaged.
Its commonly reached when CPU is at 90-100% load with stock cooler. And that is the temp of OCed CPUs with custom cooler at 100%.

Yes it shouldn't be sustained, no it won't cause damage if achieved (for a while).
Check your CPU usage when temps go over 65C. It should be more than 75% with stock cooler and 80% with af cooler.

PS: I hope you're talking about Celsius Not Fahrenheit.

Okay, so if I'm reaching 79 degrees at stock with the 4790k (boosted, so 4.4GHz), with the Vcore above, everything is ok? That's while in Prime95, which I read uses AVX instructions. I tend to get to around 60 degrees in Battelfield 4 and about 50 in lighter games such as Skyrim. I'm yet to try any conversion or rendering but will do so in the next week. Will a video conversion in HandBrake run cooler than Prime95?

I'm new to Intel you see, coming from an FX8350 that never breached 60 degrees, hence my panic. Thanks a bunch for answering a noob mate :)

Everything will run cooler than Prime with AVX instructions.
To give you an example, running prime95 28.3 brings my 4790k into the 90's, with my scythe mugen 4. Running OCCT/AIDA64 gets it to 65-68C max.
Video rendering doesn't get it above 60C, gaming just into mid 50's (not playing very demanding ones).

To give you some more information, 72C is the recommended max. package temperature. The temperatures you're reading are core temperatures, which can be up to 5-6C hotter. So you're looking at a recommended max. core temperature of 77-78C. I would second this, wouldn't want to run it above that point in everyday use. I still don't think that if it did, it would heavily damage the CPU. Current CPU's are designed to throttle themselves back to prevent thermally caused damage, that throttling occurs at 105C core temperature.

So yeah, your temps are perfectly fine. Mines are higher and I still don't spend a second worrying.

Its never a problem assisting a new member here :)

Firstly, I am a VFX university stud, and I have the same CPU, albeit with Liquid cooling, check my sig.

Prime 95 does take the CPU to its limits, so yes the temp is totally fine. Some people even get high 80s when they run it.
I get anything b/w 67-72C when running turbo and using Prime 95, but that's with liquid cooling, expect it to be 5-10C more with stock coolers, which it is in your case- that's absolutely fine.

Its good to see that your CPU is comparatively cooler with stock cooler while playing BF4, since its very CPU intensive.
I've already mentioned the ideal temps for doing different tasks in this thread above:

30-40C when idle.
40-50C when streaming/ browsing/ mild gaming
50-60C when heavy gaming/ video rendering
60-70C when gaming at ultra or rendering heavy files.
Its OK to get upto 70s in very high usage.

Those are with stock coolers, subtract 5 to 10C with af coolers.

Yes HandBrake will run cooler than Prime95, but it really depends on the level of rendering you do. If you render short videos like 30 mins HD then it may go upto 60-75% load and maybe in 55-60C bracket.
Converting FHD movies will really test the CPU, like 80%+ load and expect around 60-70C with stock cooler.
I can't really tell for sure, but yes it'll be cooler than Prime 95.

Its amazing how your AMD didn't cross the 60C mark, as its very common for AMD to heat up faster than Intel.

Playing games can take your processor in late 60s temp. Especially CPU intensive like BF4 in multiplayer.
That game takes my CPU to 70C+ in Ultra in heavy multiplayer(more than 40 people on server), but I use 4k display so that's understandable.
Try out BF4 Ultra in multiplayer when server is under heavy load, your CPU with stock can heat upto lates 60s temp or even early 70s, that in FHD.
If you wish to heavily OC, that is above the turbo level, I'd strongly recommend to get af cooler, like a Noctua NH-D14, which is a really excellent cooler.
Otherwise, as long as you don't run your CPU with heavy load all the time, that is around 80%+ most of the time, you don't need af cooler.
Hope I cleared your doubts?

Hmm okay I see. That seems okay then, so as long as the CPU doesn't sit at 79 degrees for a prolonged period? I mean I'm using a Dark Rock 3 to cool it, which is supposedly the best single tower cooler. I just expected temperatures with a bit of headroom you see.

As long as everything is okay, thanks again :D

So you have a af cooler! I didn't notice that in question post, my bad.
Well yes the temps are okish as long as you don't sustain it for like hours.

While I do some serious VFX and video rendering, with commercial 3D Studio Max on my PC, my CPU occasionally touches 72-74C, which, without my cooler, would have been 78-84C on 100% load. But that doesn't cause any damage to CPU since its just for minutes of super heavy computing and not hours.

And Prime 95 is supposed to check the CPU for those kind of usage and 79C with that cooler isn't bad, it isn't the best either though. If you really do OC the CPU to its limits and do insanely CPU intensive tasks, then you might want to consider Noctua or even Corsair Liquid coolers for that matter.

I think you're good to go :)

Your temps are better than mine (well, your cooler is better). Make sure to use as little as necessary QUALITY thermal paste. Saving money there is the wrong end, imo. Get something like MX-4 or Arctic Silver 5 (which needs some time to become fully effective).

Okay I'll look into that. Will have to do it on a day where I have some free time as it was a quite a strenuous process to get the huge Dark Rock 3 on. Just one more thing, I've been looking at CPU-Z and whenever the CPU boosts to 4.4GHz, it shoots the core voltage up to 1.239V. This seems a little bit high compared to the 1.05 that is displayed in BIOS, especially when noting Haswell's sensitivity to voltage.

Here is a screenshot:

Z8vP2oU.png


The thing is, when looking in BIOS, when I look at changing the core voltage I can't figure out how to change it. I change from 'Auto' to 'Manual' but there is no way of actually changing the value. ASUS Maximus VII Ranger, in case anyone else knows.

Sorry didn't see your first post! Yeah that is a bit of relief, these chips sure run hot right? I'm using MX4 right now, worried I may have put a little too much on but I'm sure I didn't :( Does MX4 need a curing time?

I'd rather leave it to the BIOS to maintain the voltage until I want to OC above turbo boost. VCore should be the last thing you should try your hands on. Leave it on auto as long as you don't want to seriously OC.
And you can OC above turbo for a couple of 100Mhz with the Multiplier alone, no need to tamper with the VCore.
I use the CPU @4.5GHz and My VCore is Auto, I've just set the XMP profile in BIOS while tweaking with multiplier.

I've been told it doesn't need, but my temps dropped quite a bit in the first few days of use. First time I also applied too much (like really, too much xD) and after reapplying my temps went down by 10C to what they are now. You shouldn't expect such high temp drops, though, as your current temperatures seem pretty normal and totally fine to me, just a little higher than I'd expect with such a beast of cooler.

Absolutely NO. There has been so many occasions where people, myself included ended up with a 1.35v vcore on stock speed given by the auto setting of the motherboard.
I'm now running it on 1.135v and could go even lower to 1.12v without crashing.

So shall I consider myself rather lucky to be able to run @4.5Ghz w/o tampering w/VCores? The VCore is not dangerously high too, 1.25V to be precise.

From what I've seen, yes. I didn't try oc'ing on auto vcore, but I'd expect it to go beyond 1.4, whereas I only need about 1.18v to 1.2v for 4.5ghz.

Anything under 1.3 should be fine for long term use, though.

I understand. My VCore fluctuates b/w 1.2505-2.285V. I have checked like 100 times in an hour while doing heavy VFX rendering and that was the result. So I guess I'm in the safe zone with Auto.
