The other day, I bought some IC Diamond 7 carat thermal paste from Petra's Tech Shop. I ordered at about 5:15 PM my time and they SHIPPED it to me about 10 minutes later and it got to my door today. I was quite eager to apply this stuff to my B3 Q6600 and I must say the results are impressive.

Here is a bit of background first off.

Anybody who is a true computer hardware enthusiast these days knows that keeping your CPU from overheating while pushing it to its limits is one of the most important concerns. Thermal compounds like Arctic Silver are the front line of that defense, conducting the heat directly from the CPU to the heat sink. Without the compound, small imperfections in the surface of the heat sink can render the heat sink almost useless and lesser compounds can actually insulate your processor. Thermal compounds that are available for purchase have remained unchanged for some time. The most popular type of thermal compound has silver suspended in silicone grease. Research has been done by overclockers.com demonstrating a far superior type of thermal compound using diamond. Silver has a respectable thermal conductivity at: 429W/m K. Diamond on the other hand has a thermal conductivity of 900-2320 W/m K. So worst case scenario we double performance, and best case is roughly a 5x multiplier.

Another nice advantage with diamond is that it is not electrically conductive. Silver based compounds will conduct electricity which makes a sloppy application of the compound a risk for shorting out your expensive hardware.

It appears that several people have come up with this idea independently, but we didn’t want to make that fact stop us from sharing our two cents on the matter as well. There are mumbling's about commercially available compounds being in the works but we thought, “Why wait when we can have our candy now?” We are going to show you how to make your own diamond compound, and provide you with some of our own results for the improvements it provides in actual cooling performance. We will be comparing Arctic Silver to our home brewed batch of diamond compound.

This tube of Diamond paste is 7 carat and not 25 like what was used in the link. In fact, I cant find anything less than or greater than 7 carat at the time of this writing.

Here are the specs for the IC Diamond 7 thermal paste:

Size: 1.5 gram tube
Thermal Conductivity: 4.5 W/m-K (data acquired with an ASTM D - 5470 thermal interface test instrument)
Thermal Resistance: 0.25°C-cm2/W@ 100 µ BLT
Electrically Conductive: No

Here are my idle temps using AS5

Idle
Load
47*C
67-70*C
Respectively

With IC Diamond 7 carat:

Idle
Load
39*C
55-57*C
Respectively

I highly recommend this product to anyone who is looking into a new type of thermal paste for your cooling needs. My max temp is now what my IDLE used to be!

Now, since I have a Q6600 (B3 stepping) and my CPU used to idle at 50C. It is overclocked to 3Ghz as my board and stepping limit me to go any higher. I applied the IC Diamond thermal paste and it dropped my temps by 10C! Now, I idle 40C and my max temp (under load) never goes above 55C. I highly recommend this product to anyone who is looking into something better than Arctic Silver 5. If you are, look no further than this!

There are a couple of draw backs however. The first being that it is very hard to get out of the syringe because it is so thick. Second being is that it does NOT spread like Arctic Silver so you do end up using a bit more than you normally would.

For single core users, I recommend putting a pea size dot in all four corners and one in the middle. Dual core users, I recommend putting a horizontal line going side to side (<--->) and stopping right before the edge. Quad core users, I recommend making an X shape on the CPU.

One part of me says to buy 5 sticks and another part says to wait a while longer. I think I'll wait a few more months.

The only bad things I have to say about it is that you dont get enough of the thermal paste in the syringe and it is very hard to spread and push out.

That's why I was going to buy a lot of them...save on shipping.

Is it so thick that the heatsink won't be able to spread it out when it is put on?

To be honest, Im not all that sure. I didnt want to waste the stuff so I guess Ill find out the next time I take the HSF off. Hopefully soon as I want to get a new mobo.

I will defentaly be getting more when I get the money. Im going to get it in bulk. :_)

Id still use this over AS5 any day now. I woudlnt have believed in this diamond stuff had I not tried it myself.

I just didnt want to put the HSF on, take if off, check the gunk, take it back off and put it back on again. To much of a hassle and a waste.

Im debating putting it on my video card now.

A sample of one constitutes "Results are in."??? I had no idea Crash held such commanding power in the hardware community! lol

Anyone have a good UK supplier of this? it looks pretty damb awsome :):)

Having voices in your head is normal. Listening to them, common. Arguing, acceptable. However, when you lose the argument, you're in trouble.

That is very interesting. I like how my thread is mentioned twice on two separate websites. :)

I have 3 tubes. One i bought from Petra's (Directron.com has it cheaper though)and the other two i got for free.OCforums was offering free tubes of IC Diamond 7 carat thermal paste and ended up sending me 2 tube's..lol.But im waiting on my Ultima 90 before i use it.I dont want to waste it on a Thermaltake TMG i1 even though its a good heatsink.(A little better the the Arctic Cooling Freezer 7 Pro )there isnt much in the tube.I peeled back the cover on one

see open tube

Has any one confirmed the actual carat weight of diamonds in the tubes? I should think 7 Carats plus the suspension medium would comprise more material than appears to be in that syringe.

When you buy 7C, 10C, 25C, etc. it would be nice to know that's what you're really buying. Or, are they "cheating" and supplying 7 Carats of weight of diamond + suspension medium?

When I get my new motherboard next week, I will post a pic in this thread showing what the IC Diamond paste looks like after applying the HSF.

If you ignore the dust collecting on your heatsink after 4-5 month, you have wasted your good money on fancy greases. A dirty heasink can raise your CPU temp by 3-4C.
It's hard to get into the grooves of some heatsinks to get the grit out, so every couple of years remove it, wash it with dish detergent (of course remove the fan) rinse it well ,dry it. Reinstall!! Good luck

"3-4 degC" is within the margin of error of some of the temperature monitoring systems*

I'm not going to worry unless I'm within maybe 15% of the maximum value permitted by my CPU specification (or there is a sudden, significant, and unexplained increase in the temperature).

Even then, I'd try alternatives to such drastic action first. I could easily create a higher temperature issue by simply performing the Heatsink Assembly uninstall/re-install procedure, and I could easily damage something during the procedure as well.

The risk to my computer just isn't worth it for only 4degC.
