Overclocked R9 temperature issue, what's the best solution for my custom loop? - Page 4

Stress Tests with one dual 240mm Radiator in push configuration

I5 4690K Overclocked @ 4489.28MHz Stress Test with IntelBurnTest

Update
After Cyro999's post I decided to add a very quick bench along with some information from HWInfo which shows all relevant (well most) data. The new stress test (HW264 modified by "Angelotti") is more appropriate for haswell stress tests and didn't nearly fry my CPU like the other one in this post.

HW264 "Angelotti version"



HWInfo Screenshot




CPU-Z



HWMonitor - Massive 90 Degree Celsius Temp at max



Intel Burn Test - Maximum stress settings



Sapphire R9 290 Overclocked @ Core: 1170MHz Memory: 1500MHz Benchmarked using Unigine Valley

I was looking for the best stress tests for GPU but there seems to be a lot of debate about stress tests providing unrealistic scenarios, the test is to see the impact of adding another dual radiator to the rig so I'll use Valley to provide a baseline






I've logged GPUZ temperatures to a file while running Unigine Valley and here are the max temperatures:

GPU Core Start Temp: 50 Degree's Celsius
GPU Core Max Temp: 69 Degrees Celsius
VRM1 Start Temp: 46 Degree's Celsius
VRM1 Max Temp: 91 Degree's Celsius
VRM2 Start Temp: 43 Degree's Celsius
VRM2 Max Temp: 59 Degrees Celsius



Later I'll strip the rig, clean, re-thermal paste and install a secondary dual 240mm radiator and re-test

You shouldn't use IBT on Haswell.

Even if you want to use Linpack (the test contained in IBT), you would use an up to date version, not the years old version in IBT. The problem with doing that is that it's a synthetic FPU stress test, with avx and avx2 instructions that causes it to draw twice as much power as a regular 100% CPU load.

That means that you will hit 100c on CPU using that test with an overclock tuned to max at ~55c while encoding video at 100% load on all cores, because you are stressing the CPU in that certain niche way. Because of that, and because there are tests 30c+ cooler that are more demanding on vcore and overall CPU stability, there's no real reason to use Linpack ever - outside of either Benchmarking (see my sig!) or testing the highest power draw possible for your VRM's or cooling solution (which shouldn't be neccesary)

I guess if you're running it, you have not read the guide on OCN so i would suggest doing that since you have and are playing with Haswell CPU @overclock - http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics/ - several sections in the dropdowns cover temperatures in different loads, what is good or not good to use, etc.

You have a Gigabyte motherboard, i'm not sure which or if it's exactly the same for you, but the z87 and some z97 gigabyte boards did not show accurate voltages with CPU-Z newer versions. It was best to use Hwinfo (not hwmonitor, go to www.hwinfo.com, download it, open the sensors tab) - and look past core VID (because VID is not voltage) - look at the Vcore sensor near the bottom. It should also show Input Voltage (VRIN) somewhere, too.

Hi,

Thanks for all that information, I've had a descent read and there's so much I need to learn. I've downloaded HWInfo and altered the arrangement so the things I need are in one place. I'll run H264 and see what happens and compare with that smile.gif
