OCUK Official IC Diamond/ Perihelion Test Results

Okay I tested the IC Diamond 24k TIM.... I was using arctic silver 5 TIM

Idle temps I didn't bother with because they are always low. The cooler i'm using is the ZALMAN CNPS 9700 NT @ full speed all time 2800rpm and the CPU was at stock 3Ghz (Auto BIOS settings for CPU). I used Prime95 on the large FFT's test. Room temperture was 21c.

Load temps with AS5 (6th April AS5 was on 6 months and cured)

core-0 57c
core-1 53c
core-2 52c
core-3 52c

Load temps with IC Diamond 24k (6th April ICD24k 1 hour on and not cured yet)

core-0 54c
core-1 49c
core-2 49c
core-3 49c


I used core temp to monitor core tempertures. Still waiting for the IC Diamond to cure really only been on for about an hour. I used the pea size method 5.5mm of IC Diamond and pressed down.. The AS5 was put on about 6 months ago and had cured and I used the spread method to apply the AS5 back then.



P.S I thought I would be nice and post my results even though I never got a sample of the stuff.. Happy with it so far and was not as thick as I expected it to be after what people were saying here, it actually is better for the ZALMAN CNPS 9700 NT because it stops the wiggle they have even when fully tightened. So it's more sticky for sure compared to AS5. Also the fact AS5 is slightly capacitive has put me off using it now because of that fact. The great thing with IC Diamond is now I can use it on the GPU without worrying about killing it or having to buy a non-conductive or non-capacitive TIM.


Nice Job guys so far im impressed but have to admit was skeptical about it making a big difference. The difference for me is really 3c less then AS5.



Okay todays Load temps after it had time to cure.. Room temperture is still 21c and again used Prime95 on the large FFT's test.


Load temps with IC Diamond 24k (7th April)

core-0 54c
core-1 49c
core-2 48c
core-3 48c

Hi I have done tests with IC Diamond and IC Perihelion along with Artic Silver 5, Noctua NT-H1 and MX-3. Artic Silver, MX-3, and NT-H1 were all on for 5 days each just but I never usually see any difference after 5 days anyway.

I have the i5 2500k @ 1.3v and 4.6ghz, Using a Noctua NH-D14 CPU Cooler running from a 12v molex so full power 24/7.

Ambient and Idle temps were taken after the PC had been left to cool for an hour after having been running folding at home all night and morning, rather than taking the temps after after boot, as my PC folds rather than switches off. Max temps were taken after 2 hours of IntelBurnTest as Prime doesn't push it nearly as far as IBT (about 7c less with prime95).

I used the 5mm pea sized blobs in the center of the CPU and let it air for 15 minutes before fitting the heatsink, I also re tightened the heatsink the day after fitting just to make sure it was tight, but noctuas seem to tighten right up on 1st attempt anyway. I will say that the 5mm pea size blob is a bit too much for my CPU as I had spillage onto either side of the socket, I found a 3-4mm blob covered the whole of the CPU except about 1mm of each corner of the CPU so that was better for my size of CPU.

I applied the paste in the morning, then did the tests 48hrs later with both ICP and ICD.

So here are my reults

Must say I am very impressed with the IC Diamond it seems to work instantly with little or no curing time, won't be using or recommending anything other than this from now on.

Big Thank You to Andrew (IC Diamond) for the samples and if I have missed anything out I can easy re-test or do additional testing if required (un-employed so have the time :D )

I done my testing with an i5 2500k at 1.3v and 4.7ghz, using a Xigmatek Dark Knight cooler on max rpm of 2150. My idle and ambient temps were taken after PC had been on for 2 hours all 7 case fans on max (NZXT Phantom) My old paste (MX3) had been on for 3 weeks. I used a 5mm drop of ICP and ICD and like above I had spillage so 4mm better for me too. I left both pastes on for 48hrs before testing using 20 runs of IBT and 1 Hour of OCCT and then taken an average of the temps.

MX3: Ambient 21.6c
Idle 33.8c
Max 63.9c

ICP: Ambient 21.4
Idle 33.7c
Max 62.4c

ICD: Ambient 21.7c
Idle 33.4c
Max 59.8c (1st time ever below 60c with any TIM on IBT :) )

Thank you very much for my samples and like above if you need any more info I can easy re-do etc

Will update in a week to see if it cures. Then will switch to Perihelion
 
Just started my testing by taking stock paste readings using my 'method' Temps hit 86c in LinX before I BSOD'd and rebooted :(

Think my stock paste is just about done lol - will (hopefully) get the IC Diamond on later today or tomorrow and see how that performs!

Strangely enough, I can't help but feel my cooling performance has dropped since I opted for a push/pull fan setup - is that possible? could my cooler perform better with one fan pushing?

It's a Thermalright Ultra-120 eXtreme ...what d'you think?

>edit<
on a side-note, anyone else with an ultra120 extreme find it really easy to move the heatsink when it's clamped in place? is that a design flaw or is my cooler mounted badly?

Heres mine, original paste was As5 which I had just put on last week so its had about 5 days to cure (is that enough for fair comparison?)

Setup is i52500k @ 4.5ghz and Megahalems with a single cruddy coolermaster led fan with 2 leds borked :D Motherboard is open on desk atm as i have no case. Still all tests done in same conditions.

Here goes, just ran Linx hope thats ok? In Order of testing (core temps min to max 1 - 4 under each picture)

either this stuff is way better or my AS5 wasnt cured or seated right?

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 :)

5-C0:73 C1:73

Just for kicks, I turned the two tri-cools up to 'high' setting and did another run - now I didn't do this with the stock paste so I have nothing to compare to, but the temperature didn't rise above 58c!!! The noise from the fans would be unbearable for 24/7 usage but it's an impressive temperature drop at the flick of a switch!!

That seems to be massive difference between the two thermal compounds. Were your GFlops values in the two tests more or less similar and what did you get?:)

Push-Pull will always be better than just one fan as your cooler is drawing in more air across the heatsink. However you may only notice 2-3C difference with Push-Pull.

Thermalright Ultra-120 Extreme seems to have 4-screws mounting system if I am correct. Did you tighten the screws down fully?
 
screws were screwed fully down yes - the stock paste had been there for months (maybe longer) - it wasn't freshly applied as I didn't have any (hence not actually knowing what it was at first)

GFlops for stock were 23.33-23.39 and for ICD was 23.02-23.08 so near enough

When I took the HSF off to clean off the stock paste there wasn't much on there, so possibly just not enough to do the job in the first place

I think you should re-apply stock thermal paste and let it settle in for 3-4 days and then repeat the test and see what you get.:)

Edit: So you have no idea what was your stock thermal paste called? lol :p
 
I don't have any of the stock paste - the system was given to me by my cousin and he doesn't have any of it either (I asked him for it yesterday) he said he threw it out as he uses MX3

I guess my results are pretty useless then :( for what it's worth though, I'm (very) happy with it :D

>edit<
no, no idea what it was - he just said 'the paste that came with the 120' - he's not the most helpful lol

Or what you can do is to borrow some MX-3 from your cousin and repeat the tests. That way we will have better idea on how the two compounds performed in your system:).

Edit: As MX-3 is one of the main competitor and is a high-end product itself, it will be very interesting to see the comparison.

Yeah, I'll ask him :)

On a side-note, is the clamp for the IFX the same as the clamp for the 120?

If so, how do you hold the damn thing still while you mount it!? is there a knack? Or doesn't it matter if it rotates slightly?

No.

IFX-14 is two-spring loaded screws mounting system.

If you go back to post 291 in this thread, I have listed the mounting procedure.

Basically there will always be some movements when placing heatsink on top of thermal compound as heatsink will have a tendency to slide. The aim is to minimise these movements as much as you can:).

When I place heatsink on top of thermal compound, I tend to hold the heatsink in that position and then apply pressure using both of my hands for about 1 minute.

It is very tricky to ensure you get a good mount.

I was dying to buy the IFX from OcUK but they stopped selling them by the time I had the money to buy it :( I am a jealous man lol

You could buy the Thermalright Silver Arrow and it has a better and more user friendly mounting system and performance will be more or less similar to Thermalright IFX-14. :cool:
 
Yeah but that's silly expensive lol

When I was looking at the IFX it was only £30 lol don't really wanna spend £55 on a cooler to be honest

(even though it does look bloody awesome lol)

Besides, the cream/blue fans look gay lol
