Latest update - any errors or omissions on my part let me know and they will be corrected.

You didn't put in my 'after' temps... the 'failed stress' text flows accross all boxes - maybe put my load temp as 85/FAIL and that should stay within the one box :)

Incidentally, for the "TRUE 120" does TRUE stand for ThermalRight Ultra Extreme? or is the TRUE a genuinely different cooler to the ultra120?
 
Got some IC Diamond 24 and Shin Etsu x23 coming, so will update the thread if you want more results and/or comparisons.

Corsair H70 with 2 Akasa viper fans, 2600k at stock.
 
Looking at the results table, my temps have not been posted and my cooler is listed incorrectly, the correct details are as below.

IC Diamond results as per image, tried to post from excel but no it wouldn't work!

Cooler = Coolermaster Hyper 212+ pull/push fans

Only chance I get to do this is late night (1:30 am) so prone to some error. I was feeling good about the accuracy on this one though.... Thanks for the corrections keeps us honest.
 
The proof is in the pudding as they say..


Idle - stock paste (Shin Etsu)................................ Prime 95 - stock paste (Shin Etsu)

i7 2600k, stock speeds, with a Corsair H70 cooler, and Akasa Viper fans in push/pull (instead of the corsair stock cooler fans).

Both load readings were taken first, to avoid the artificially "cool" temp from a freshly started PC. I ran Prime 95 (small FFTs) for 3 hrs+, and took a load screenshot, then left to sit idle and cool for 1hr, and took an idle screenshot.

Very happy, that's a 5C reduction at idle, and 3C reduction at load on the hottest core!!

I'm now considering doing my GPU :)

Q6600 @3.4GHz

Before Compound (Akasa AK-455):
Ambient Temp: 24
Idle Temp: 36
Load Temp: 78

ICD
Ambient Temp: 24
Idle Temp: 39
Load Temp: 84
 
Always one that goes against the grain isn't there lol

You sure you had it mounted right/right ammount of ICD etc?

Incidentally, found out that my ultra 120 extreme would've come with Chill Factor compound :) so that's what was on there in my initial tests :)
(though when it was applied is anybody's guess!)

The Diamond seems to be favored mounting wise on the Corsair water coolers.

What makes the mounting different from the others?
 
Hey IC Diamond, just wanted to let you know I have recieved the samples, generous samples they are too, thanks. Will be submitting test results in the next couple of weeks after testing is complete.
 
Updated the results with corrections - Recently switched from Windows to Ubuntu mostly pretty good but had a devil of a time converting the spreadsheet to a graphic.

when you mount h70 heat sink you hat to twist it to lock it in place same goes to h 50 ,

need to try this stuff see what difference will get to the mx-3

edit: bought two 7 carat ones for 10 £ should be enough for 2 cpus

Sent it out to sensor products for analysis today - when they process it they email the results in a excel file when I get them I will forward them to you. Maybe by the end of the week.

Nice:)

Since moving from my old Thermaltake Big Typhoon cooler to Thermalright IFX-14, the base of the latter felt different. Big Typhoon seemed to have more of a flat base whereas mounting of IFX-14 felt a bit more awkward as it tended to produce slightly more movement sideways.

The convex base of IFX-14 has now been confimed by the pressure and contact test. It will be very interesting to know the average pressure exerted by unlapped IFX-14.

Judging from the contact pattern, I would say that unlapped contact pattern or the 'I' pattern isn't making a good contact at the centre as colour seems to become lighter in that area.

The 4 cores in Q6600 are aligned horizontally as shown below numbered 1 -4 with contact pattern superimposed roughly (paint work:D) :

As seen above the light pink colour is emphasising lighter contact in the centre as seen in the original picture aswell. It is interesting to note that unlapped IFX-14 seems to only partially cover core 2 and core 3 areas while no contact is made with core 1 and core 4 areas.

So more heat is accumulated faster at Q6600 IHS than can be transferred by IFX-14 via heat pipes resulting in higher cpu core temperatures overall. May be this another reason why there is 6-8C difference between hottest and coolest cores on my Q6600.


To me this suggests that unlapped IFX-14 base or even unlapped Q6600 IHS are a poor heat transfer mechanisms

I am very glad that I took part in this thread as I have learnt something further about thermal compounds and mating contacts between heatsinks and cpus. Plus it has been an eye opener into the world of PC cooling:):cool:

It will be interesting to see how the contact and pressure results along with thermal compound results turn out when I lap both the IFX-14 and Q6600 in near future:)
