Something I picked up for fun to check if theres really anything to it since there was a lot of gimmicky stuff mentioned on their home page

http://www.innovatio...om/overview.htm

The product



Hardware i7 2600k @ 4.2gigs, 1.3vcore in some horrible Chennai heat with very little ventillation

The result

Test 1 - Arctic Silver 5



OCCT linpack test - temps were around 75-76C.This is on a Noctua D14 cooler with 2 120mm fans (75cfm), one 120mm rear exhaust and one 230mm top exhaust in the case

Test 2 - IC Diamond



OCCT linpack test - temps around 72-73C mostly stablized at 72C towards the end, this was a fresh install whereas the AS5 had 5 days to cure. Also this was the same D14 with a single 120mm and top 230mm exhaust on the case and no rear exhaust fan.

So looks like it does what it says on the box plus has some geek value to it


Cons:

You might lose cpu warranty if not careful since it is very abrasive and needs to be removed carefully - Check pics here -> http://www.tomshardw...iamond#t2424949

Edit - Picked up from Amazon.com

"if anyone wants to lap his cpu", what does it mean?
Lapping the CPU means using sand-paper and other means to make the integrated heat-spreader as flat and polished [read mirror finish] as possible. It is said to improve the temperatures on the processor, though it is all anecdotal and hasn't been recorded substantially.

The IC Diamond Paste is so abrasive that it was re-purposed for lapping.

Hope this explains the topic clearly Sire, Cheers!!

From what I googled diamond is a good conductor of heat but doesn't conduct electricity

Really? I was always (like from school days) under the impression that diamond was a good insulator of heat and electricity, maybe kinda like glass.

yep diamond is better heat conductor then graphite.(this question came in IIT JEE paper this year and i marked the opposite answer
thought free electrons for graphite might give better conductivity)

Heat or electricity? or both?

Edit: just googled
Turns out it's a good electrical insulator while being a good thermal conductor. Guess there is more to it than just bling!

Back to the OT! So this product really is a better TIM than the silver compounds?

Bottle has a Ph.D in Physics, and has a number of patents in the field of nanotechnology. Trust him

lol you must be scratching your head pretty hard later. This we learnt in 7th-8th mate.


Also what is its price?

As5 is one of the worst available today. Mx2 mx3 mx4 are better. Cm ice fusion is better. Prolimatech is better almost everything available today is better than as5. Though diamond is still the best just not worth the price

Was ist das?

Mein Freund schicken --> http://benchmarkreviews.com/index.php?option=com_content&task=view&id=150&Itemid=62&limit=1&limitstart=12, the Cooler Master IceFusion cnnot hold a candle to the Arctic Silver 5's performance. In the review I have provided Cooler Master IceFusion is a 'Grade C performer' whilst the Arctic Silver 5 is a 'Grade A performer'.

If you feel why I have used German, it is because every issue you pose a view but don't provide appropriate proof.

I seriously doubt the veracity of the above review as they have not mentioned, whether they gave the Arctic Silver 5 [and other Arctic pastes in general] the requisite curing period before testing them. Generally the performance of all Arctic pastes goes north ones the Cure in time of ~200 Hours in satisfied.

Also the same guys quote on the Cooler Master IceFusion --

http://skinneelabs.com/pk-1-asm-cmif/

Cooler Master IceFusion[font=Helvetica, Arial, FreeSans, sans-serif] is a high-volume, budget paste. It comes in 40g and 200g tubs and at extremely low costs; the 200g tub can be found for less than $20. It’s a white paste that’s usually pretty thin but separates into two components: a thick white paste and a thin oil. This means it requires mixing before each use for consistent performance. In the [/font]AMD Installment[font=Helvetica, Arial, FreeSans, sans-serif] of our last review we showed it was a poor performer, but that’s why it’s being included in the early portion of our 2011 Comparison: having a reference point for a ‘bad’ or ‘generic’ TIM can be important for people looking to upgrade.[/font]

[font=Helvetica, Arial, FreeSans, sans-serif]Well, there were a few surprises here, I thought. First, IceFusion isn’t the worst overall paste to be run on this testbed, Spire SilverGrease SP-457 takes that honor. IceFusion’s worst-case performance is really worrying though; as cheap as it is, it would be useful for when you have a lot of area to cover, like with GPU RAM and VRMs, but those typically have poor contact, making IceFusion a bad option. That said, if you build a lot of systems and have to get TIM via retail channels (and are confident in the contact your coolers make to the chips), IceFusion is pretty interesting. It’s extremely inexpensive and because it thins so well, very little needs to be used. However, if you don’t know how good contact will be and don’t need extremely inexpensive paste, it would be best to avoid IceFusion.[/font]
