OCUK Official IC Diamond/ Perihelion Test Results

Another question... As stated further up, I'm running two Antec TriCools on my Ultra120, when I have both fans at the same speed, it's silly loud (unless they're "low") but if I put the 'push' fan on "high" and the 'pull' fan on "low" it's still pretty bearable and seems to be shoveling a lot of air out of the case... could this be an effective setup? or would the difference in fan speed just be causing an airflow bottleneck inside the cooler?

Also, although these two fans are rated at the same speeds as per the switch control, naturally there could be some difference between the speeds yes? especially as they are on different molex strings etc... could these factors affect their speed? should they both be first on different molex strings or should they both be plugged in back-to-back into the same string?

I think overall the cooling across the heatsink may decrease slightly as you have the pull fan at lower RPM. However I don't think it will affect the pattern of airflow across the heatsink as such which is usually disturbed the moment it impact upon heatsink fins.
In other words If there was no heatsink between the two fans, the airflow will be travelling in a straight direction theoretically between the two fans. With the inclusion of heatsink between two fans, the flow pattern of air is directly affected by it's impact with the heatsink

If they are same rated fans, then imo it shouldn't matter whether the two fans are connected via one molex string or are attached separately to two molex strings as they will be using same amount of voltage provided you don't use the fan controller to manually change their speed.
 
Yeahhhh! Finally got mine yesterday after it being sat in some post office 'gawd knows where' for the past couple of months.

I'm very impressed with ICD 24 especially with the cure time and the temps on the E6600, I'll be using this in future over AS5 (which I used to swear by).
 
Ive been using ICD for a couple of years now thanks to an american friend pointing me its way.

Tested it on a HD4650 with a zalman v770cu fitted running silently as the pc is used as a HTPC mainly. It was using icd for about a year with these results:

method
Half an hour idle then 30 mintues + of furmark 1.9 xtreme burning, displacment mapping stability test using gpu-z for temps.

ICD
Ambient temp 8 degrees
idle 29 degrees C
max 42 degrees C

Perihalion

Ran for 7 days 30 mins idle and 30 mins burn in.
ambient 9 degrees C
Idle 33 degrees C
max 49 degrees C

The temps never changed unless the ambient went up or down. ICD rules.
 
Just a quick one from me. Have been using the paste I got with my TRUE 120 on a 1055T clocked to 3.8Ghz,

Was idling at 38c with a room temp of around 21c.
Under load would reach 58c.

Have just applied IC Diamond and idle is 30c and under load is now 48c.

I will say that this is everyday use and not stress testing. Basically the temps whilst the computer sitting idle and when I am gaming or encoding a DVD.
 
I'm well impressed with the stuff.

This was from a couple of weeks ago with AS5 - been on for about a month :

This is today with IC Diamond - been on for 3 days :

Wasn't expecting as much as 4-5 degrees tbh, AS5 is deff showing its age :)
 
Thanks people for posting up your results and taking the time to test. Not as many as I thought for wall of shame candidates.

Will be updating ongoing results with corrections in a day or two

Just started my work with ICDiamond - for starters I want to say that the Thermalright Ultra 120 eXtreme is an absolute ARSE to hold steady while screwing it back down!!! I hope the twisting motion won't bugger up the performance of the TIM!! lol

Also, is this enough/too much/not enough...

(by the way, that 'artifact' in the northeast of the image is dust, not a big scrape!)

First impressions: when booting with the stock paste, CoreTemp registered a temp spike of 65c, first boot with ICD registered a peak of only 58c - good start! It doesn't seem to need any 'curing time' so I'll proceed with my testing of the ICD now... will post results shortly :)

Hard to tell from the picture but Looks a little to the low side maybe 5mm? when I have time I will resize and do an overlay. This is where the artful guess comes into play - you put your thumb into the picture and say a little more or a little less...

Sorry for the delay in testing, been manic!

Anyway my results are as follows:

MX-4:

Ambient - 21.2C
Idle - 31
Load - 64

ICD:

Ambient - 21.4C
Idle - 29
Load - 62

Spec as in sig and 2500K clocked to 4.4Ghz. I'm only running the one fan on the heatsink too as temps don't seem to require 2.

Cheers for the opportunity to test
 
Anyone used IC Diamond on a GPU? am looking to do my GTX 480 and was wondering how much I should use as the area is a lot bigger and not all that much pressure can be achieved. So would a larger blob spread and work the same as it does for a CPU or is a different application method required?

I put some ICD on my 4770 and the temps didn't really improve as much as I hoped - I don't think the pressure exerted by the gpu cooler really helps at all - perihelion might work better as it's thicker, but that's a test for another day :)

GPU temp right now (while browsing this forum and playing a movie to the tv in 1080p for my son) is sitting neatly at 45.5c It seems to've helped the loaded temps, but the idle temps seem a bit higher

Ok thanks very much. I have tried 3 times with ICD on my 480, 1st I did a large 8mm blob in the centre, took off heatsink after a few hours and the paste had only covered about half of the GPU, then put on a 10mm blob and it wasn't much better, now I'm using a 12mm blob but no more paste left to try again so am hoping that is enough paste. My motherboard is getting swapped so waiting for that to return before I can test temps. Impossible to spread ICD so has to be a blob method. If I get higher temps after next test I will just go back to another brand for the gpu, one that spreads and I know is completely covering the area I want it to.

I am still waiting for the pressure and contact measuring kit:(
Click to expand...

Ok just received the kit today:D. Thanks for the extra IC Diamond tube:cool:

I have two packs A and B. A contains 3 brighter papers and B contains 3 slightly darker papers.

Now how will I conduct the test exactly? What software program do I need to use to display pressure values and contact pattern? I was thinking may be the kit will be similar to gauge equipment but I don't see any wires?:confused:

How will the pressure and contact results be displayed on the screen?:confused:

Alternatively "X" pattern works great - If it is not spreading it is most likely a pressure issue.

I would re-torque the screws periodically over a few days to take up slack as the compound thins.

Take one of both A and B and place glossy sides to the IHS and sink with the "Frosted" sides facing each other.

One is the donor and the other is the "Print"

Mount your sink as you normally would with out paste.

Dismount sink remove paper - throw away blank piece

Sensorproducts.com has a pressure interpretation sheet that you can use as a general guideline.

You have to return the print to me which I send to sensor products for analysis. - sorry I forgot to leave instructions for a return mail envelope with my mailing person.

Raw image will tell you a lot out of the gate and you can compare to the review and if you post the i9mage I can give you some feedback on it till you get the analysis.

Can be used to improve contact and performance -progressive lapping etc.
