Core temps on my i7 3930k

[Dave3000]

When I run Prime 95 (small FFT test), after 7 minutes individual core temperatures range from 64C-70C. During idle, core temps are in the low to upper 30s. My CPU cooler is a Hyper 212 Evo (stock Evo fan replaced with a CM 120mm Blademaster). With the stock fan of my Hyper 212 Evo temps would be around 66-72C under the same conditions during full load. I actually bought 2 CM Blademaster fans for my Hyper 212 Evo, since I wanted matching fans for a push/pull configuration. I had the 2nd Blademaster fan as a pull fan and it didn't seem to lower the temps so I removed the 2nd fan. Standard fan speed setting set in the BIOS. Are my cores overheating?

 

[Dave3000]

I overclocked my 3930k to 4GHz and set vcore to a static 1.2v. After 7 minutes of running Prime 95's small FFT test, core temps ranged from 67-73C. Is that too high for a 3930k oc'd to 4 GHz at 1.2v?

 

[Markfw]

Nope. Your cooler is a little weak for this giant. @4.5 I needed an H100 water cooler as my megahalem was not enough. Right now @ 4.3, and back to using my megahalem.

 

[cmdrdredd]

Not too high. It's within the safe range. For a 6 core CPU stressing all 6 cores at the same time it's a lot going on.

If you're worried about temps, you can adjust the overclock down or try a better HSF.

My Hyper 212 Evo is advertised to work with Socket 2011 motherboards. Maybe not weak for not overclocking?

It works with that platform yes, but it might not be able to handle 6 cores under 100% load with as much ease as it can handle a 2500k running 4.2Ghz.

+1 just because it'll fit doesn't mean it is ideal

just means it can fit and should not damage a stock running cpu. Overclocking goes well outside those limits.

Isn't water only preferred with 2011. Even intel's cooler for them is water. Right? Don't even think below a H100 for 4.3-4.5 with them.

I stay in the high 60's @4.6ghz with my NH-D14 (ambient temp of 20C). I did add an extra fan though, so I have 3x120mm fans sandwiched on the side, middle, and side of the HS. My idles are 33-35C right now, and I top out in the mid-high 60s after 4-5 hours of stress testing + AVX. Add 3-5C to both idle and load if my ambient temp is 25C+.

For about $80, it wasn't bad ($70 for NH-D14 + $10 for extra OEM fan).

Or 4.6GHz

Intel makes an air cooler for socket 2011 as well that you can purchase separately.

Good airflow in your case helps quite a bit as well.

This. Besides, ambient temps make a diff of 5+ c in my case in general, I dun have 2011

Its not worth 25 IMHO.

zalam btter imoh

Then get evo

 

[exar333]

It doesn't make sense to invest in the s2011 and cheap-out on cooling over $30-40. Get a GOOD air cooler or water if you are serious about a decent OC. If you want stock, the Intel, or any other half-decent solution should work fine.

Been thinking about this cooler as well but luckily finding this thread via google saved my from disappointment,have been using the stock air cooler from intel and unless i ramp up the fan to like 100%,its virtually impossible to keep under 70 cel at stock speeds but at 65%,it still hits 74 cel in a moderately warm room under prime95,the evo seems to not do much better either sadly enough.

Is the noctua nh-d14 a vast improvement over the evo for stock cooling and perhaps a 4ghz oc?I hear keeping this chip under 70cel is really idea but is it even possible under air cooling for a mild oc?

 

[Idontcare]

NH-D14 is pretty darn good, hard to beat. Costs a bundle because of that.

Have heard some claims that in some cases,people actually have had better load temps with it then over some water kits,if true who knows but it def seems like a good choice for air cooling,if not the best period.

Saw some pictures of it housed in a antec 300 which is the case i have and its freaking vast:awe:

I have 10 120mm fans worth of high end radiators cooling my CPU, VRMs, motherboard chip and 2 GPUs. In total with the Gentle Typhoon fans the setup can cool a little over 1KWatt such that the long term water temperature would never be more than +10C from ambient. For the 500W I actually put into it the water over all the components fully utilized the temperature would be just +5C. This is an extreme water cooling setup. With just the CPU going like in this test its just +2C (as measured by my temperature probes on my fan controller).

A 3930k @ 4.5 Ghz with 1.35 V (offset +0.02V dynamic voltage) stable 24/7 will run at a peak of 64C with Prime95. So its about 5-10C better than a prebuilt/sealed water loop.

What is interesting to me is that previously I could not get this chip to 4.5Ghz, then I upgraded my water cooling and its now stable and with a lot less tweaks. Its also 15C cooler. So it got me +100 Mhz so far and I still need to push more.

 

[Grooveriding]

Get an NH-D14 or another substantial cooler. Water is not really necessary and doesn't make a world of difference between a really good air cooler on these chips unless you are trying for the fastest possible OC you can achieve.

My temperatures are only slightly better than they were on an NH-D14 using water, and then it's mostly idles where I see the biggest difference, which are about 20-25C depending on the core. Loads are in the 60s, with the big difference being if I push it to 5Ghz with over 1.4V they stay in the high 60s to low 70s, whereas on air they were in the 80s and likely 90s if I'd of ever let it run like that for an extended period.

I have both the NH-D14 and the H100, and the H100 is only just a tiny bit better than the NH-D14 (by a few degress). So the NH-D14 would definitely be expected to be better than basically any water-cooling that is less than the H100.

 

[skipsneeky2]

While prime95 has been awesome for stability testing,is it really the best as far as checking thermals?

I have been running cinebench 11.5 and i notice with a 4ghz oc that my temps won't really hit over 70 cel after many repeated runs,but according to coretemp prime95 puts a extra 40w load on the chip,giving me 78-82 cel load temps.
