ARCTIC COOLING Freezer 7 thermal paste vs. Arctic Silver 5

Hi I am about to put together a new computer. I am going to put in the Arctic Cooling Freezer 7 cpu fan/heatsink. It comes with thermal paste on it. Should I use that as the thermal paste or arctic silver 5 or both.

If I should use only arctic silver alone then what would be the best way to wipe the thermal paste from the fan? Thanks in advance for your help.

Use which ever makes you sleep better at night, cause you more then likely arent going to see such a huge difference ( if any ) in temps.
 
I'm fairly sure it's still MX-1 but, still decent TIM, for the initial installation you may as well keep it. If you have to re-install later you could use AS5, MX-2, TX-2 or shin etsu with pretty similar results or IC diamond 7 if you want the best of the best. The first 4 I listed are going to be within about 2C of each other max.
 
i don't know about better, I really think that there is no real way to test the differences in thermal pastes within 1-2C of each other. it's really easy to get that big of an ambient temperature change that big while testing, not to mention the different ammounts of load that can be put on a processor even at idle windows desktop just from standard windows background stuff on a fresh install. 5% cpu load is more than enough for a 1c difference and 1C ambient change may not get picked up by an ambient sensor if using one and there are no thermal probes used on PC's more than +-1C accuracy. If they're withing 1-2C I say it's a tie, there's just no way to gaurintee that there were absolutely no other factors present unless using a specifically designed test rig and not relying on possibly warped heatsinks and/or IHS and even slightly differing ammount of TIM and even maybe an extra twist when seating a heatsink using one paste and not another, the stuff is too sensitive and the margin is too tight.

Still MX-1? No matter. It's better than AS5 and pre-applied, so why not go with it?



Because of it's built-in "electrical" characteristics, almost anything these days is better than AS5 !

You must never use AS5 in a situation where sloppy application could allow spillage onto any pcb tracks carrying high freq switching signals ---> usually, but not confined to, a potentially serious issue with vga cards ?

Because Arctic Ceramique is "electrically" inert, i've always preferred it over AS5 for a long time now ---> and found it to be just as good a thermal interface as AS5 !

These days, just about every TIM is electrically inert. So in my opinion, assuming they are equal or better thermally, any of them would be a better choice than AS5 !

As I have stated numerous times....

Most if not all top quality heatsinks ship with a very good thermal paste that is at the very least as good as if not better than AS5!!

Makes no sense in the world to purchase a real nice heatsink ands then have the manufacturer ship crappy thermal paste!!

Peace!!

I think you overstate the issue a bit...

I refer you to
http://arcticsilver.com/as5.htm

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.)

also, as sticky / thick as AS5 is, I have never had any trouble keeping it on the CPU & HSF and off the mobo.
