hi. ive had a heatsink for a year and a half and was wondering when/if i should get a new heatsink. there seems to be a little rust on it. How long do heatsinks usually last and how can i tell when they are going bad?
Wait rust? What kind of heatsink? An OEM intel or amd heatsink are full aluminum or aluminum with a copper core. Aluminum's "rust" looks like white powder but doesn't flake off like ferrous metals (steel, iron). Copper will turn green but I doubt that your heatsinks are oxidizing! Ideally you never need to replace a heatsink given you do a little maintenance from time to time. A pic would be great......
its a heatsink and fan that came with my amd phenom x4 965. mayb its not rust but the copper (or what looks like copper) changed in color a little to mayb silverish? i would take a picture but i dont have a working camera atm
also what do you mean by maintanance? what should i do to maintain the heatsink? thanks!
Maintenance just consists of blowing it out with compressed air to remove dust. If you use an actual air compressor dont crank it up to 90psi or at least use something to keep your cooling fan from spinning. This is not necessary but something I learned to do just in case. You could spin the fan up to high with the compressed air and nuke a bearing or the contacts within the motor. But canned air works fine too. You also want to check to make sure that the heatsink isn't loose. You do this by poking the side of it with your finger and if it moves you have a problem
If the copper looks like an old penny where it is just a little brownish then I wouldn't worry about it. However, if its silverish it doesn't sound good. For it to be literally rusting the computer would have to be in a high moisture environment. Like a leaky basement, garage or outside. If your computer is on or next to your desk inside your house then chances are after a year it isn't rust!
