i got an intel i7 930 currently using the stock cpu cooler. im planning on buying a new cpu cooler that newegg has on sale and i was wondering if i need to remove all the old thermal paste from the cpu in order to use the new cpu cooler. if i need to remove it, how would i get all of it off. i assume scraping it off is not an option.
this is the one im looking at btw http://www.newegg.com/Product/Product.aspx?Item=N82E168...
You will need to remove the old thermal paste and apply a new application. You can remove the old compound with a high % isopropyl alcohol or a cleaner specifically made for cleaning thermal compound off components.
I have that model cooler and I have been very pleased with it. It should come with new thermal paste but I prefer something of higher quality such as artic silver 5.
I'd also recommend Shin Etsu over AS5.....if ya read the Artic Silver site, you'll see that it takes 200 hours and a lotta thermal cycles to cure which benchmarkreviews estimates can take over a year of normal usage.
After this article was first published, there was an immediate backlash from some of the manufacturers listed in this review. The primary argument was the lack of cure time. Here is the Arctic Silver 5 recommended cure time instruction from the manufacturers web site:
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.
So by my estimation of this statement it would take almost a year of normal use to properly cure the AC5 compound, or almost nine days of continuous power cycles to meet their recommendation.
