OCUK Official IC Diamond/ Perihelion Test Results

Probably the simplest would be to press down on the sink for a few moments to spread the compound some before locking down.

Also on coolers with 4 mounting points, tightening 2 diagonal points simultaneously then the other diagonal gives even pressure. My cooler has 2 mounting points so I press it in position (it's big & heavy anyway) then while holding it tighten the 2 sides hand-tight, then alternate a half-turn either side with the screwdriver until fully tightened down.

Can't imagine Diamond will squidge about much anyway it's very dry.
 
Q6600 @ 3.6 ghz 1.46 volts set in bios LLC enabled all tests done under same conditions in a closed case with the same fan config.

Thermalright archon cooler 2x Ty-14 fans at max rpm maximum cpu plate pressure.


Arctic silver 5
IBT 51 runs at 44 G/flops per second
Max temp = 83c

Obviously arctic silver hasn't had time to cure
-----------------------------------------------------
Arctic cooling Mx-3
IBT 51 runs at 44 G/flops per second
Max temp = 78c
-----------------------------------------------------
Ic diamond 24
IBT 51 runs at 44 G/flops per second
Max temp = 81c

So looks pretty much of a muchness identicalsih to mx3 to me although I shall be trying out several remounts and application methods tomorrow to rule that out.
Just wanted to get the IC diamond on tonight to have a look I probably have a dodgy mount tbh or have use too much / too little.

Yeah I find the two screws mounting system to be more trickier to work with than 4 screws mounting system. When fitting the heatsink onto the cpu IHS, I find that 4 screws mounting system provides greater stability and even balance and there is less chance of heatsink movements.

I have IFX-14 and it also has two screws mounting system. The heatsink itself is huge and I have to be more careful when tightning the screws. Even then there is still some movement when trying to 'align' the heatsink with cpu.

My previous cooler was Thermaltake Big Typhoon and it was much easier to install as it also had 4 screws mounting system and the system itself was very user friendly.
 
X method works great and entrains no air and final results are same as applied bead. My preference towards the bead on center is more of economy for the end user as people tend to use more with X applications. But that might be my bias as I have infinite amounts at my disposal and always slap on enough without worry that I need to ration it.

I did not think it necessary as it seems straight forward to me but we could put a window on the label and spec something like 0.15-0.2 ml per 30 X30mm

To me its easier to judge length over diameter. However I have stuck to the Pea method for all my testing in this instance.

I installed IC Diamond yesterday so should have my results up early next week.
 
I5 @ 3.8 ghz, 1.24V, Titan fenrir cooler. Unknown room temp.

MX 4:
Idle 40
max 71

Ic Diamond:
Idle 38
Max 68

Impressive results :)
 
Cpu = i7-920 @ 4.2 Ghz
H2O Cooler = EK-Supreme HF (Full Nickel)

Using prime95 (small FFT) to test.

Original MX3

Ambient Temp = 22c

Idle Temps after 1hr
Core 0 = 48c
Core 1 = 48c
Core 2 = 47c
Core 3 = 47c

Full Load Temps after 1hr
Core 0 = 78c
Core 1 = 77c
Core 2 = 78c
Core 3 = 77c

IC Diamond

Ambient Temp = 22c

Idle Temps after 1hr
Core 0 = 46c
Core 1 = 46c
Core 2 = 46c
Core 3 = 46c

Full Load Temps after 1hr
Core 0 = 75c
Core 1 = 74c
Core 2 = 75c
Core 3 = 74c

Nice results and thanks again :)

In case your wondering my cpu temps would be lower but I also have my 5970 in the loop as well. ;)
 
CPU X6 [email protected] and 6950@6970 in water cooling loop.

Testing Mx3 and IC diamond on CPU waterblock only. (waterblock is a heatkiller 3.0 with custom mounting so pressure unknown, used the same amount of turns on fixings with both pastes)

Using 10 runs of LinX 0.6.4 to get load temps roughly 45mins of testing.

Idle temps taken after 24hrs of normal use (left alone running windows and background tasks only for an hour)

Fans were kept on minimum for both tests, i have no way of measuring ambient temperature.

Mx3
Idle 29C
Load 38C

IC Diamond
Idle 29C
Load 37C

So some incredibly unscientific testing to come to the conclusion that it hasn't helped my temps but to be honest they are very low to start with. People with systems pushing the cooling on there CPUs might benefit more from the 2-3 degrees difference that some people are seeing.

I didn't use the IC Perihelion but will on my next customer build.

Ive got to say thank you to the people at IC for the give away its much appreciated i will buy another tube when this runs out (3 tubes for £15 is about as much as i would pay ;))
 
How on earth do you get load temps that low? My rad is mounted on a windowsill drawing cold air through it and i can't get near those temps?
 
yep the AMD CPUs run a lot cooler than Intel its the main reason i swapped as i had a Matx case at the time but max recommended temps are 55C not 80C so you have less to play with.
If it makes you feel any better playing BC2 pushes the temps to the 40s :)
I think the most impressive thing is that if i had full fans on the temps move about 5C from idle..even running an I7 set up with a quad and a thin triple i used to get a change of 20C
 
Finally had some free time to get round to doing a bit of testing. :)

Specs are my sig rig;

i7 950 @4.1
x58 extreme
noctua dh-14 with both fans @ 10v, clamped as hard as possible
lian li pc-p80 case w/ case fans on high

clean w7 sp1 install on 80gb hdd with background stuff turned off and no lan
using aida64 to monitor temps
using LinX with the same settings entered for all tests
18,000 btu air conditioner switched on to keep the room at 21.5c, switched on for 45 mins before any testing began and run during tests

old paste: ocz freeze, clean application, allowed 2 hours to burn in on linx
new paste: ic diamond, clean application, allowed 2 hours to burn in on linx

old paste:
idle after 2 hours
Core 0 = 46c
Core 1 = 47c
Core 2 = 47c
Core 3 = 46c

load after 1.5 hours
Core 0 = 77c
Core 1 = 77c
Core 2 = 76c
Core 3 = 77c


new paste:
idle after 2 hours
Core 0 = 44c
Core 1 = 44c
Core 2 = 45c
Core 3 = 44c

load after 1.5 hours
Core 0 = 74c
Core 1 = 75c
Core 2 = 74c
Core 3 = 74c

Fantastic results for just a change of paste, highly recommended stuff.

Also a big thanks for the sample. :)
 
Here's the results for Diamond 1 week into testing. All the conditions are the same other than W7 SP1 has been installed, don't think that should make any difference.

Nice results bainbridge.
So it does go to show that some 'settle in/curing' time is needed before testing can be carried out to get better picture of TIM performance. That's why I will be using my PC for general use, gaming etc for few days after the application of each TIM to rack up 65-70 hours of settle in time before carrying out testing.
 
I think I'm going to have to set up a proper test system for this as it's a bit of hassle swapping TIM on my main PC. I've swapped over to the Diamond stuff and my temps have increased by a few degrees over AS5 even to the point my overclock crashed out when stress testing earlier. Going to give a few applications of each just to see if it's a bad mount or what.
 
The AMD's don't get hot. My friend has one with the corsair cooler and it barely gets over 35 full load

If Bulldozer turns out to be as promising as we hope i may have to jump ship then. Should be looking at single figure temps in the Winter. :D
 
I don't think AMD have die sensors though, so it's not a comparable measurement of temperature in relation to Intel?

Different measurement the nearest Intel come is there Tcase sensor.

But i used to have a 920 in a set up and it was heat throttling the X6 with the same cooling would happily run at 4Ghz (i know they are not identical in performance but at the time they were the 2 top consumer CPU ranges) as to be expected really you pay for performance in heat (until they have the tech for a low power but powerful CPU), that's why there is so much interest with items that can knock 2C off of you load temps and that's why IC are in business.

I have already re-applied MX-4 and this was two days ago. I will be testing MX-4 after one week. Then I will apply IC Perihelion and test it after one week and then IC Diamond and test it after one week aswell. So will be hopefully posting results in 3 weeks time.

@ IC Diamond

I apologise if I go over the 30 days limit but I want to ensure that testing is as accurate as possible. I could have tested the 3 compounds by now but my feeling is that they won't be performing to their respective optimum level fresh out of the box and as confirmed by bainbridge results in post 213.
Even for MX-4 it says there is no curing time but I don't believe it. Imho any TIM that you apply will need some settle in/curing time.:)
