IC Diamond 7 Carat Thermal Compound maximizes thermal heat transfer between the CPU core and heatsink by taking advantage of diamond's superior thermal conductivity

Purified synthetic diamond has a thermal conductivity of 2,000-2,500 W/mK compared to 406-429 W/mK for pure silver.

Diamond's five times better thermal conductivity compared to silver makes it a superior heat transfer material for cooling high performance CPUs and is electrically non-conductive and non-capacitive.

Application: IC Diamond is composed mostly of diamond powder, and as such is quite thick. Proper application is critical to optimum performance. Squeeze onto the center of the CPU an amount of IC Diamond compound about the size of a pea - the center of the CPU is where most heat is concentrated. Place the heatsink on the CPU and push down to spread IC Diamond over the CPU's surface. Clamp the heatsink and power up the PC.

Curing Time: IC Diamond requires minimal time to attain peak performance; in most cases, IC Diamond will reach peak performance after two hours of use.

Stability: IC Diamond is designed for stability - it will not bleed or separate in normal use.

I don''t know if I put it on wrong or not. i put it on like every other kind I''ve ever used. But I applied this to my cooler and start my machine and watched the temp go up to 80!! I cleaned it off and put Arctic Silver 5 and I''m running at 36. I''ll never use this again!

I''ve tried many other tim''s while working in a computer shop and have to say this is the best for the price that I have come across. Need to try the shin-etsu but when it comes to my personal rigs I will use this. While it does scuff the IHS and cooler a little it''s just surface marks and wont affect anything. On cpu (NH-D14) I saw a 5-6 degree drop instantly. As for gpu it was only about a 2-3 drop on average but the max is down about 5.

My loads dropped 5''c load from Artic Siver 5''s load on my GTX 570. Yes after a 10 day period of burn in for AS5. Application was simple, pea size dot for CPU,2 pea size dots for GPU. Heating it up with hot water helps the spreading. I heard about leaving the TIM on the GPU for 10 minutes before contact was also needed, tried it on my GPU, didn''t really see a difference compared to the CPU drop. Well worth the price. FOR NOVICES: DO NOT SPREAD THE TIM WITH YOUR FINGER, DOT METHOD IS THE ONLY GOOD METHOD.

I''m not really impressed with this thermal paste and it''s mostly because of the hype, graphs, and charts that I saw before ordering. It works, and the temps are okay...but it''s not a godsend by any means. I''ve used this now on 6 different chips, and not a single chip has had a noticeable drop in temperature when compared to any other basic thermal paste. I''ve tried the spread method, the pea method, and experimented with applying different amounts of the paste, and each time my load temps are 50C - the same as they are with the lame $3 silicone paste from my local computer shop. I guess for novelty of "hey I''m using diamond powder" it''s cool - but as far as functionality don''t bank on it being anything amazing. I applied this to my laptop''s cpu as well because it tends to shut off when it gets too hot (typical) and it was currently mounted with silicone paste. I applied the IC diamond, burned it in, and it still shuts down due to CPU overheating. I used the pea method and got a great spread with it. So overall I''m not impressed and wouldn''t bother ordering it again. I''m glad others seem to have good results though...

at least 20 degrees differnce on my GPU great product fast shipping thanks
