Ivy Bridge temperatures

[vhx]

Hello everyone, it's been a while since I built a new machine and have overclocked (from the first Core 2 Duo).

I recently bought an Intel i5 3570k along with an Asrock Z77 Extreme 4 motherboard. I also bought an aftermarket HSF for it, the COOLER MASTER Hyper 212 EVO, which seems to be pretty popular. After looking at the different reviews given by people with 3570k most people seem to be getting temperatures of 29-30C idle and 40-50 under load (or so they claim), WITH overclocks.

However, my temperatures seem to be around 37-40c idle, with or without overclock (due to the lower clock and power saving features I assume). However when I run OCCT to stress the machine, the cores spike up to around 68-72c! Are these normal temperatures for Ivy Bridge? It seems a bit on the high side, especially for an aftermarket cooler.

I just used the thermal paste that came with the cooler. Would it reduce my temperatures a bit to maybe get some AS5? Speaking of thermal paste, how long does it keep? I built my last machine about 4-5 years ago. I bought a tube of AS5 I never fully used, I just dug around and found the tube, and surprisingly it still had some left and was still fluid. Is this still useable or maybe it's too old?

Thanks for any insight.

Its normal. Anything below 105C is fine.

Stock cooler they are around 40C idle and 80-85C under Linpack.

40-50C load and OC? Hah...

 

[amenx]

No your temps are not normal. They are below normal for IB. Also I dont recall any reviews with 40-50 load temps for IB, must be a mistake somewhere.

 

[coffeejunkee]

Ambient?

But sounds fairly normal. Keep in mind these stress tests raise temps much higher than most normal programs. If one gets 50c overclocked they are not using a very stressfull stress test. Which OCCT test you use? The Linpack one should give highest temps. Or use Linx with AVX and set amount of ram to max. And like Shintai said, you're still 30c from max.

One thing about the cooler, it's got direct touch heatpipes so normal way of applying thermal paste does not work so well. Better to spread out before placing cooler. But it wouldn't matter too much, maybe 5c tops.

Also check fanspeed. You can't compare your results with fan on automatic control to someone with fans at 100%. And when overclocking your vcore is the most important. Leaving it on auto will usually supply more than needed so temps get higher.

 

[graysky]

Temps are more a function of vcore than of frequency. What is your vcore under load?

I haven't used OCCT; is it using LinX? If not, run Intel Burn Test (LinX) at maximum strength for a while, 4 threads, and see what that gives you. Make sure you have AVX installed (should automatically be installed with your mobo's drivers); you know you are doing it right if your GFLops is in the high 90s, like 95 GFlops.

My old 3570K in a somewhat less powerfully-cooled case, using stock 212EVO fan and stock 212EVO paste, idled in the mid-30s and hit 65-74C under maximum Intel Burn Test load. (Three cores in the 65-70C range, one problematic core at 74C at normalish room temperatures of around 20-25C. Cores at max load were at 1.2v or slightly less IIRC, so not at great batch or not a great mobo or both; probably the mobo's fault as it was a cheaper Gigabyte z77 board.)

74C is fine and a little on the high end but still well below Intel's max temperature limit.

For what it's worth, I built another 3570K system that is almost identical to yours, but with minor improvements here and there, and it got the temps down to 70C or less for all four cores. The CPU came from another batch, which may have helped (I don't have the data in front of me right now but the max load vcore was somewhat lower, more like 1.15v rather than 1.2v; could be the mobo and not the CPU batch though). Also, I used a Blade Master 120mm fan and PK-1 in place of the XtraFlo 120mm and stock CM paste that came with the 212EVO. I am running a Extreme4 Z77 mobo as well, with 4x4GB 1866@1.5v memory and a Gold-rated PSU to help keep temperatures in check. The mobo has crappy fan control but I'm using 50C temp target + level 5. According to HWInfo64, this is keeping the fan low noise but as temperatures get over 50C it starts spinning up to max speed. Eventually.

Also, your case could help. I won't go into details except to say that my current case has massive airflow.

All temps above are for stock settings only.

Mrm, never mind...

Reading, it helps.

My 3570k @4.5ghz using a Zalman CNPS9900MaxB cooler idles at 30C, load 71C (prime 95 small fft), with 23C ambient temp, and load vcore of 1.27v. Your load temps look fine, idle is a little bit high but fine, are you using fixed voltage or offset? I don't think I have heard of anyone getting 40C - 50C under load on IB, not even under water.

Reading, it helps.

Whoops!

3770k @ 4.2ghz 1.15v hits 78c on core 3 no matter how many times I reseat. Temps are very good while gaming, just IBT heats it up good.

Core 3 is the natural hottest core, followed by core 2.

50 @ load o'ced with an ivy bridge i5 would be great!! I am running the 3570k with gigabyte-u3dh board, and a corsair h100 closed loop water cooler, and i run 31 @ idle and 68 @ load with no overclocking, if i bump it up to 4.5ghz i start hitting 95-100 per core, the people who claim they are getting 50 C are using the motherboards cpu temp as their basis. Which is incorrect, this is a sensor that is located between the dies, it is not the actual CORE temps, use coretemp or realtemp for the most accurate readings on the 3570k i5. The only way to get more out of the ivy bridges is to delid the processor and replace the thermal paste under the IHS. I would use something like artic cooling mx-4 or Arctic Silver 5 thermal paste.

Extreme oc'er - I think Idontcare knows of a trick to getting better temps out of an H100. I can't find the thread but I hope he sees this and can comment.

In fact, the reason why de-lidding gives you better temperatures is because you reduce the space between the die and the IHS (provided you do it properly) - not the typically assumed reason of the stock thermal paste being poor.

Check this post for more details on what I mean.

Will my i5 2500K at 4.5GHz and my 2 GTX 460 1GB at 840/1680/4100 in SLI be able to play this new game. Everybody's probably running it on SLIed GTX 670 2GB.

Heh, I wish I knew of a trick To get maximal performance out of my H100 I had to lap it because the darn thing was concave (like a bowl) so it would form a big gap filled with TIM in the middle of the block right over the CPU.

That did improve performance. If anyone is looking for improved cooling from their H100 I would definitely recommend that they check the flatness and if it is concave (edges are higher than the center) then lapping it will improve the thermal conduction.

Stock H100 water-block:

Hatch-mark with blue sharpie, lightly sanded to remove the high spots, leaving the sharpy markings still in the middle which indicates the middle was the low-spot:

Nice mirror finish with 3000grit:

Lapping the H100 dropped my temps by 3-4°C on a 4.5GHz 2600k (also lapped).

I delidded my 3770K and put Liquid Metal Pro between IHS and die (resealed with high temp gasket silicon). It's running @ 4.7GHz 1.25V (no V tweaks, just multiplier change in BIOS) and 63C temp average with HS fans set to lowest speed settings. According to Core Temp while running Prime95 small FFT's, hottest core is always Core #2 @66C which runs about 6C more than lowest temp core #3 @60C. Could go higher with V tweaks, but too lazy cus it's fast, cool, and quiet as it is.

Heat sink is a Thermaltake OCK Frio (almost exact copy of Megahalems inside with different fan shroud) on a p8z68-M pro. MX-2 paste between IHS and HS. Would have used the Liquid Metal Pro between the IHS and HS also, but wasn't sure on HS base construction metal (Gallium in Liquid metal Pro eats Aluminum).

68 to 72c is normal and what intel would hope most get. If that is on full load thats a good temp... But you should have a good OC like 5Ghz and good cooling solution. gl
