    I upgrade my computer every summer, and its rolling around that time again.. and I was wondering if Thermal Paste expires.

    I've got a tube of Artic Silver from last summer still almost full, and I'm wondering if it'll still be good for this build or should I add another tube?

    Haha, don't know why I'm even bothering since its only about 5 bucks a tube, haha

    I think artic silver is a bad idea, in itself. I hate that crap. Doesn't cool any better, but has several downsides... Including being conductive, and that it hardens over time (despite their marketing) which can cause damage to cpus when removing them.

    I've never had a problem with the stuff, and its been the best of the brands I've tried

    It was the one recommended on most computer entusiast websites, and was recommended to me by friends on my first build.

    I'm gonna disagree with Jolly, I've always had great luck with Artic Silver, never any problems.

    The thing that perks my ears is, that you say its spreading normally?

    Usually the best way to apply it is the peadrop technique in the middle. the less space between the processor and heatsink. There are also TONS of reviews that show that artic silver does reduce temps by 4-10 degrees C

    Squeeze about 3/4 of an inch stripe out of the tube and check for oil separation. If there is oil separation in more places than just the first little bit you squeezed out, you need new paste. Unless you feel like re-mixing it by hand.

    Thats how I normally apply it, and thats not the question, haha...

    I just put a drop on a piece of paper and it didn't come out thick or watery or any other weird affect, so in my humble opinion, it looks okay.. but I'm wondering if anyone has used year old thermal paste before...

    FYI, if the surface you squeezed the test sample onto is clean, there's no reason you can't use the test sample instead of wasting it.

    To check the condition of the paste. I'm pretty sure he is not saying to use that much on the processor.

    Ok, that makes sence then.... but either way, I dont believe it expires, its meant to stay on the cpu die for quite some time, and 1 year in a sealed bottle doesnt seem like much

    The heat of the CPU will cure the oil into a thicker, gel-like form, whereas the oil in a tube of heatsink paste sitting around on a shelf will stay liquid and the metal component (especially silver, because it's extra-heavy) will settle out over time.
