Product Description

Contains 99.9% pure silver: Arctic Silver 5 uses three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer.
Not Electrically Conductive: Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)
Absolute Stability: Arctic Silver 5 will not separate, run, migrate, or bleed.
Performance: 3 to 12 degrees centigrade lower CPU full load core temperatures than standard thermal compounds or thermal pads when measured with a calibrated thermal diode imbedded in the CPU core.
Coverage Area: The 3.5 gram tube contains enough compound to cover at least 15 to 25 small CPU cores, or 6 to 10 large CPU cores, or 2 to 5 heat plates.
Important Reminder: Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

I will buy it again if needed.

I applied this thermal conductor compound to a heat sink and was able to spread it with a single sided safety razor without any voids or extra thick or thin regions.

Arctic Silver 5 is the best thermal paste on the market and it was the cheapest here.

Arctic Silver 5 is the best thermal compound on the market. There are other types that might be better for specific purposes (Arctic Céramique for example), but for cooling a CPU, this is the best. I've used it extensively for quite a few computer builds as well as a few 'special projects' like replacing the thermal compound on an Asus Formula X48 motherboard's Northbridge and Southbridge heatsinks.

The results are always a 4-10c drop in CPU temperatures under load. You will not notice a huge difference at idle. The real gains in heat dissipation come when the CPU is being pushed. Also, don't trust the board maker's proprietary software to tell you what your temperatures are; download a good program like RealTemp 2.41 or Everest for free (use google to find them). Either will give you more accurate numbers than Asus PC Probe, or whatever software your board manufacturer supplies.

There are some saying Arctic Silver 5 didn't lower their temperatures. That is almost certainly because they're using it incorrectly, which I can understand since the instructions provided are minimally useful. So for those of you who are not familiar with applying thermal paste, here is the process:

1. Remove the old thermal compound. This is accomplished by using Isopropyl alcohol to dissolve and loosen the old thermal paste. I recommend purchasing an ArctiClean kit. For minimal cost it will give you the compound remover, as well as an excellent surface preparer. Apply a several drops of the cleaner to the top of the chip and let it soak for 20-30 seconds. You might have to reapply more drops of cleaner again depending on how much thermal compound was present on the chip to begin with.

When i built my system i used the stock gel attached to my amd 64 heatsink.running at idle my computer recorded temps from 46-49 C and rising. At first i got a couple of case fans but still i had the same problem.According to amd these temps are normal but i heard of people with systems with much lower temps . i was afriad my system might shut down under heavy gaming.So i went out and bought AS 5 , i can tell you it is the best investment i made on my system. After removing my heatsink i removed the previous thermal gel compound and adding this , then i put my system back together and started up and .. Wow my idle temps dropped to 41 C and stayed there ,after playing half life for 15 minutes i found the temps only increased to 45 C.there is a break in period for the gel which is 200 hours, after that the gel is optimized and artic silver claims the temps will drop even more (4-12 C).It has solved my heat issue, for the cost under 10 dollars.I guess i don't need watercooling after all.Even if you arn't into gaming

this will protect your computer processor and help it run more effciently.

Arctic Silver is the best thermal paste available, hands down. It moves heat like you wouldn't believe. I don't use anything else in my machines.

My cpu isn't frying, so I guess it's working.... I haven't noticed a significant drop in cpu temps like so many other people claim to have with this product. I have used this on at least 5 processors too. I've tried different methods of applying this stuff and re-seating the HSF, but I never can get results that many other people claim to get.

I'm pretty much a "noob" and hobbyist when it comes to tinkering with computer hardware ... I stumbled into it after replacing a few laptops ... I had these old laptops sitting around, and started futzing around with them, just to see if I could figure out how to take them apart and get them running nice again ... to have a few working spares that I could then use as notebooks, multi-media players, etc. ... basically backups to use in situations where I don't want to have to upgrade old software/peripherals, or risk damage to my newer, "main" laptop.

Anyway, my second laptop ever was a Compaq Presario 700 series, with an AMD Mobile Duron processor (I know ... Stone Age, right?). My kids used it for awhile after me, and they basically thrashed it. It needed a new hard drive, keypad, AC jack ... fortunately, I was able to find all the parts I needed online, cheap enough to justify the repair effort. The heat transfer plate on the AMD processor is pretty small, not even half a postage stamp, and it's mated with a fairly large, plate-type heat sink assembly that spreads the heat across the plate, and discharges it from a fan attached to the assembly at the left side of the laptop.

Back when I was using the Compaq more frequently, I recall that it ran pretty warm most of the time, and I remember that the fan was on a lot when programs were running, at 2 or 3 speeds, e.g., low, medium, high. Well, the repairs required that I strip the whole thing down to the motherboard, and ... gasp ... remove the heatsink. Knowing that I would have to put new thermal compound between the CPU and heatsink when I re-assembled it, I poked around the 'net and saw all the good reviews on Arctic Silver 5, and ordered a tube.
