This is the official thread for results for those who received free IC Diamond thermal compound from this thread and agreed to post their results!
(First, a few words from Andrew Lemont
of Innovation Cooling)Hello and thanks to all who have agreed to be a part of this test.
This will be the place to post your benches, test, and results from your IC Diamond 7 Carat thermal compound you received.
At Innovation Cooling we have done extensive tests on our own compound as well as all our competitors and I can say from our results that I have never tested a compound that performs better although a couple come close initially on thermal performance due to a more liquid, lower particle bulk loading. This enables a better wetting of the surface to fill imperfections in the adjoining surfaces. They look great after the first couple hundred hours but what happens after 1000 hours? or 2000 hours? It is well documented in numerous published papers that low viscosity TIMs are prone to bake out and pump out. Intel and others in the OEM market recommend particle bulk loadings above 90% to minimize these effects. While this increases reliability in the long run as it is harder to pump a solid than a liquid and performance is measurably impacted as many here will probably have experienced when using thermal pads, gels, phase change, tapes and other OEM type products.
With IC Diamond we believe we have an ideal combination of thermal performance and reliable performance. Our data on a one inch synthetic die with thermocouples on die and sink show only a 1.1C delta @ 100 W. In other words a mechanically thermal perfect contact between the two would only net an improvement of 1.1C @ 100W.
Purified synthetic diamond has a thermal conductivity of 2,000-2,500 W/mK compared to 406-429 W/mK for pure silver.
Go to the company's home page for info on thermal performance/contact and pressure testing/troubleshooting and any other info you would like.ApplicationGo to this link for correct application methods.
Every manufacturer has their own prescribed method of grease application and for this test I would use our method out of the gate and no other. The application method has been tested extensively by us and independently by over 127 forum users. Lines, grains of rice, razor film spreads, BB sized, ultrasonically spread with a vibrator, mixed with other pastes have all been tried. Our recommended application is what works
. Application is simple and easy.
You may find heating it up a little bit makes it a lot easier to get out of the syringe and helps with the spreading, so mount the heatsink ASAP after application to CPU.
If you have an HDT ("Heatpipe Direct Touch
") cooler you should try using the above method first and the method used for HDT coolers later if you wish to see which works best for you.
Make sure the Heatsink and CPUs are well cleaned using Isopropyl Alcohol 90%+ pure, Arcti Clean, or something similar.Data Required
I appreciate the effort here from all participating members. Any comments pro or con are welcome as well as any suggestions. There is no bad data in this test, it is what it is, just report the result.
The data we would like is:
"Before" test data prior to dismantling your system. Make sure all heatsinks and CPUs are clean, free from dust, securely mounted, etc. We would like good data.
- Ambient temps to be taken at idle and load
- Idle and load temps obviously. Use a program like LINPACK, Prime95 or OCCT and set to max stress the CPU and allow to run for 10-20 minutes or until temps stabilize.
- Use Core Temp or Real Temp as these seem to give the most accurate readings. Real Temp also shows the max temp each core reaches during the load test. If you use another program just note down which one
- Note initial comparison paste and any exceptional conditions as well as heat sink type
- PWM disabled so fan speed is constant for both tests
- Note your system specs and settings
- Remount with IC Diamond 7 Carat Thermal Compound and repeat as above
- Submit results for any TIMs you use as a comparison also so we can compare results
Feel free to make any observations, comments or suggestions. We are trying to refine our message, application and problem troubleshooting so the information you supply to us is valuable to us and much appreciated.
That's basically it. You are pretty much on your own, whatever result you get is what it is. I may comment occasionally or suggest troubleshooting points but not much else. At the end of the exercise we will provide a chart of the results with links to the data for viewing and suggested corrections.
Thanks again all for your time and effort!
What is the HDT method? It was never mentioned in the OP and I'm having very poor results (much worse than AS3 and "white stuff"). Please let me know.
