APPLICATION METHOD


For all those participating in the IC7 giveaway,please follow this link to the Innovation Cooling website for more information on the product:

Innovation Cooling

Proper application is the key to this product. The nature and consistency of this product is likely quite different from what most of you are used to in a Thermal Compound. We don't recommend use of traditional methods of applying the TIM like razor blades, lines, x's (though some people have reported great success with the X method), etc. Through extensive testing, the best overall application method has been determined to be a pea sized amount directly in the center of the CPU. The TIM should be adequately spread via the downforce of the CPU cooler (a sufficient amount of downforce will provide best results; minimum 50psi of downforce should be the goal for optimum results. please see the Innovation Cooling website for more info). Also, for coolers/surfaces that have many peaks and valleys, it may be beneficial to wet the surface(s) with a small amount of IC7 to initially fill the voids in the mounting surfaces...then proceed with recommended application as usual. Please click on the link below for application methodology and shoot me a PM if you have any questions.
Keep in mind, IC7 has been formulated with the specific goals of providing superb thermal conductivity with short set times, but also for long term stability and performance without pump/bakeout through extended thermal cycling or usage. This stuff is very stable over long periods of time.

OK, Here are my results...

Stock heat paste
GPU: idle - 37 C
load - 67 C

IC Diamond 24 Carat
GPU: idle - 34 C
load - 64 C

CPU temp did not change after repasting unfortunately...maybe a bad repasted...
But I will soon repaste the CPU and see if the temps change...
 
Updated results tally any changes or corrections let me know.

Much appreciation for those that took the time to test and post results.

Ok i'll be waiting for my package to arrive and i'll get that done as soon as possible.

Just thought I would add some nonsense mumbo jumbo about my cpu temp, using IC Diamond of course.
I just moved to my new house and idle dropped 2c at the same ambient(72F)...According to the temp sensor on A/C panel, anyways.

In fact, with my intake cranked up to 1700rpm constant, i'm actually getting down to a 28-29c idle with a 45c load. At 1700rpm my "garbage" H50's stock fan is actually pretty quiet.

Of course this data is very non-conclusive, but at least i'm seeing low temps...

When I get that testing material(while I have my computer apart) i'll go ahead and run some more comparison tests vs OCZ freeze and see what I get... But honestly i'll be very surprised if I see a solid variation in temps. The only thing I can conclude from all of my thermal compound comparisons so far is the only variable is how well I install the heatsink...sadly.
 

I appreciate that. I have reached my real world goals also. Now my room is always comfortable(preferably chilly) with my cpu @3.8ghz. That is what it is all about. That and maybe some vodka and a glass of putang. XD
 


May be a browser issue, i'm using Google Chrome, but have you sent me instructions yet? I received the testing material yesterday... Thanks.
 



Check your PM instructions provided
 
IC would you consider doing more pressure testing I would LOVE to know if I am getting a good seat between my H50 and my I7?????
I have NO idea how much pressure is applied or if there is good contact. I think I'm going to lap my H50 but Not my cpu I don't want to void the warranty.
 


I got those tests done... I even did a GPU pressure test, which looked very snug compared to my H50. I don't know what to expect, but with all four tests it looks like the HS wasn't seated right on the H50.

I tightened it as hard as I could without breaking my mobo and did 4 tests on the cpu and 1 on my gpu. (Used all of the test material)

I got something out of it though! I used IC Diamond on my Gigabyte 5870 @900mhz Core

GPU temp before - 45c ~ 62c

GPU temp after - 41c ~ 57c

4-5c drop allover on my 5870.

Apparently I need to do some sanding or something to smooth out my cpu and heatsink surface, but no matter... My temps are good enough.





 



Thanks for taking the time to test, much appreciated


Be interesting to see to see the prints and get the lab work done
 


I could use another H 50 test I have some more contact tests slated to go out next week
 
I haven't been to Tom's in a long time, but either way I might be able to put some more ICD on my CPU heatsink, and maybe run a few tests.

Results would be interesting since the ambients are about 45C here. 🙁

@ICD, what application method do you recommend? I read this guide a long time ago, and I was wondering what your input on the validity of this would be:

Cheers. :)
 
Our Method was developed by forum users on the first 4 or 5 giveaways we did. As a group of a couple hundred more or less they tested lines, rice sized, manual spreads, cross etc. The "pea sized" amount turned out to be the best for the high viscosity of our compound.

So we spent some time investigating it to refine the method and explain results and our application instructions page was the result of the process.

This prompted the contact/pressure testing to examine those tests where people do not see a result with the end result we can explain 96% of what goes on.

There are 3 things that determine paste performance

1. Application - Amount and method used.Relatively easy to observe and control.

2. Contact - Flat is best - lap to 600 grit for best performance

3. Pressure - Each compound has their own pressure/performance curve along with different viscosity's. IC diamond is recommend 50 PSI >

If you are trying to define an application amount without the context of 2 and 3 above you are basically shooting blanks in the dark because you have no reference point on the performance curve or on the contact quality.

I believe most people generally understand that testing is a non trivial pursuit so read multiple reviews and multiple user experiences and mentally average to draw there own conclusions.

So in short I highly recommend using our method as proved out in over hundreds of user tests.
 



got a chance to review your prints today

From the images it looks like the IHS is warped in a concave with most of the force applied on the edges, a fairly typical IHS contact pattern as these things go, thats why people lap - be interesting to see the lab results on the pressure side as the edges From a quick glance seemed off the high end of the scale limit of 98 lbs.

The GPU print was very interesting, it had near perfect contact along with high pressure - very good print
 
Alright, so I'm finally getting around to posting my results.

Gaming laptop P-7801u: I originally wanted to do this one mainly for the graphics card. I then saw just how much disassembled to nothing you have to get to access that heatsink and decided against it. I may one day go back to it. But the CPU and northbridge were accessible from a panel on the bottom of the laptop.

I wasn't aware how important teh thermal pad was for the northbridge and got my fingers all over it and put it down on the counter. I then read the disassembly guide. It said you have to reuse it since normal stuff was unsuitable besides the few very dense stuff including IC Diamond, boy was that lucky.

So:

Ambient: 26°C

Before (Stock paste/pads): Idle: 29°C
Load: 42°C

After: Idle: 29°C
Load: 33°C

That's quite a difference.

I also applied it to my Phenom II X3 720 with a cooler master hyper 212+ in a coolermaster HAF 922 case. Before testing I was running at stock, but decided to overclock a little just to make a bit of a difference. It apparently barely made any difference at all. It's now running at x16 or 3.2 gigahertz per core. Also I used speedfan and the AMD overdrive for reading temps, they still looked lower than ambient, so I guess you'll just have to use the delta between the two. Also, the cooler ran at different speeds so if it had run at the same speeds this new stuff would have done even better.

Ambient:26°C

Before (AS5): Idle:22°C
Load: 31°C Fanspeed at load: 1068RPM

After: Idle: 20°C
Load: 29°C Fanspeed at load: 966RPM
 
Alright, more results for you.

Core 1: 59°

Low, Cooling Down from Load:
Core 0: 48°
Core 1: 47°

Δ Between Ambient and Cool Down Low:
Core 0: 21°
Core 1: 20°

Idle After Fan Speed Stabilized:

Core 1: 8°

Cooling Down From Load:
Core 0: 3°
Core 1: 4°

After Fan Speed has Stabilized:
Core 0: 5°
Core 1: 5°

Notes to the test:

The high temperatures allowed by the stock thermal paste where enough to cause the CPU to throttle, severely impacting useability.
Since the reapplication it has not throttled once and is quite a bit more usable.
In addition, the fan ramps up noticeably slower and peaks at a much lower level than with the old thermal paste.

All in all, excellent gains with every application of IC Diamond [:jaydeejohn:5]
 


Did you just happen to buy that laptop on Ebay? haha I sold mine, it was a P-7801u(Edit : I think it was 7805) with 9800m gts and 2.8ghz T9600 processor.

Anyways, I just posted a video on youtube showing a small benchmark in gtaiv using ic diamond... cpu was running warmer than normal at idle. Here is a link.

btw, what the $*(# is this above me! LOL
