IC Diamond24/Perihelion4gm Giveaway

I have measured the dimensions of the IFX-14 base and these are as shown below:

Height of the base = 15mm

I think it is almost impossible getting perfect surface contact and pressure, looking at my pics and also as confirmed by your results. All different cpu coolers have different mounting systems coupled with cpu IHS which as you mentioned can be concave or convex. So it does seem to be like a trade off between different variables.

IC you should set up your trust.

As per thermalright making their convex bases, this forum has shown time and again that people still spread, line, cross, dual line, squggly, @sign, TIM in the name of your last lay, ect. when a blob in the middle works best.

Thermalright have been clever in that they make sure each of their heatsinks press and spread TIM off the centre, effectivley applying the blob method to all methods of application and making exact contact with the central cpu no matter what the spreadding method.

Lapping a thermalright will not aid temps if you do not use the pea method, if you do, then it will, I knocked off 2mm of nickel and copper from my true lapping, pea method is the only decent way, your advice has made me really think about using <enough> as in to interface the cpu fully with the heatsink.

I think that most of your results are people applying TIM better. However I have a lot of respect for the way you are entering the market. I for one have noticed my mx3 slowly giving, big factor here is longevity-

So IC, you have a lot of facts and figures, this might shave a few degrees off, clearly the diamond wont evaporate, what is the score on degrading TIM's.

Can you get together a hardcore of trusted users to gauge practical usage over time? I am talking review sites.

EDIT; post pic above would be to my mind a convex base with inadequate and misplaced TIM? Referring to pic above is this your opinion IC? (Wing no offence just asking)

We could test that - I have been considering changing the routine by taking a baseline compound like AS5 that everybody is familiar with and IC Diamond or perhaps Perihelion and giving away a couple hundred tubes of each and split the application method on the AS5 rice vs pea with fresh applications all the way around along with applicable ciuring times. I Have not really thought about competitors application method/recommendations. Just a thought, compounds that have more liquidity and that are rice sized in application are probably adequate for a lapped contact but amount may fall short bridging the gap on the native stock mounts with large contour issues.

As far as I know I am the only one in the retail trade that has longevity data available on site everybody is silent on the issue other than claims made. Longevity is a key factor more important than absolute performance IMO. i do have 2 and 3 year results from a limited number of end users.

The hobbyist market where everybody changes their sink every other week is not favorable to this kind of desired information - Maybe I will try the PS3 guys they only pull apart their systems with ylod and run under pretty stressful conditions. ICD has been getting some interest from that crowd on the problem.

If you really want to know about ICD's longevity you could buy a tube and check your temps monthly for 5 years or gfor as long as it lasts then you would have first hand experience;)

Intel does accelerated testing and you can do your own program - warm up your oven, take some glass slides apply some compound and bake until done - any review site could do that

Attached picture of test result was run for 20 hours at 150C, the center picture ICD is IC Diamond. The others are commonly used retail performance pastes. Not a drop dead test but it does highlight the stability of ICD7. The competition compounds feature the formation of voids, and span the range of initial failure to complete failure. IC diamond was observed to have no visible points of failure under these conditions. The picture is back lighted so the void formation is clearly visible

Additional Testing

ICD7 has been tested in a thermal cycling chamber - from -40 C to +85 C - for up to 250 cycles (with the copper block heated with 130 W of power (along with a fan heat sink) and found no change in thermal performance / thermal resistance of the grease

In another thermal test ICD7 was placed in a thermal chamber for a continuous 1000 hrs @125 C with no change in thermal performance.

In a separate test we pulled "full vacuum" on ICD7 with a mechanical pump for ca. 65 hours at room temperature. The resulting ... weight loss was almost immeasurable - 0.3 mg out of 6.2222 g. This works out to be 0.0048 wt %.

looks good to me as far as I can tell from the pictures

ON MY HONOR IN EXCHANGE FOR FREE COMPOUND I DO SOLEMNLY SWEAR TO TEST AND POST MY RESULTS

Would love to test this stuff.

I7 @ 4.2 Noctua D14 test.

P.s im sure i already posted this didnt receive anything though lol
 
Hey Virus,

This has finished now dude! People seem to read the first post and hit reply as fast as possible! Mr Diamond - perhaps you should edit your first post?

Would test on i5 2500k with megahalems cooler :)
 
Quick thanks to IC Diamond as my samples have just fallen throught the letterbox. I will keep to my pledge and give it a test at the end of the week/weekend. Got to keep the kids occupied as it is the half-term.

I am unlikely to be changing my HSF again for a while, so I would be more than happy to keep monthly records too (for longevity data sampling).

Where is my blasted postman!
 
Delivered today! Thank you!
Will do the test over the w/e as I want ambient to be constant so need to do it over a reasonable period of time, not on different days.
