    So I have had my x3370 for a few weeks now. When I first installed it, I applied Arctic Silver 5 and right away was able to overclock it to 4.0GHz@1.37v, and temps under 100% load from OCCT stayed in the 60-62°C range. At stock speeds@1.21v load temps were in the 50°C range. I've been running the CPU with F@H SMP on and off since I installed it.

    Over the past week my machine has been frozen when I got home from work. Well today I decided to track down the reason. First thing I fired up was OCCT, and right away I noticed my idle temps at 4.0GHz were at 50°C.:eek:

    Well I thought, that isn't normal. So I start an OCCT run, and not even 5 minutes in the temps were up to 70°C and rising, and then the test crashed(not that I would have let it run much longer anyway).:banghead:

    So the only thing I can think of is that the old Arctic Silver 5, which is currently about 5+ years old, dried up super quickly instead of burning in like it is supposed to. Unfortunately, I do not have any other thermal paste right now, so I am waiting for my MX-2 to come in, and I'll be applying that this week. Hopefully, that will fix my problem.

    If you want, I have MX-2 that you can borrow.

    I personally dont use AS5 anymore. Its either IC7 Diamond or MX-2.

    Damn, that would be awesome, do you still need that fan by the way?

    I've been wanting to switch away from AS5 for a long while, but been putting it off since I still have a huge tube of the stuff. I guess this finally gives me a reason to move on.:laugh:

    So thermal paste has a use by date? Very odd seeing as it has no degradable material... that i can think of so please prove me wrong if that is the case.

    Damn, forgot about the fan. :laugh: No need for it anymore. Thanks though :toast:

    When did you order your MX-2 and do you need to borrow some?

    It is on order, should be here some day this week. I don't think I need to borrow any, I just lowered the voltages and clocks back to stock and temps are acceptable until the MX-2 comes.

    Really? You know exactly what is in AS5?

    No not at all. But surely its just some silicon with metal particles to help conduct heat... right?:confused:

    Its not all that hot here. In fact, upper 50's lower 60's*F.

    And not all that funny.

    Oh yes its extremely funny .... do you wan me to believe that a paste, that the worst from the best its only 2-3 C deference .... destroyed a fine overclocked system ?

    Well my brain is larger than what birds have ... believe it or not :laugh:

    Paste does not have a use by date or shelf life, BUT it does go off, you can regen it but it needs to get a good mix so basically get new stuff. We used to use a lot of it and we found that after a year it started going off, so we sent it back to the mfg and got it back after they had done "whatever" it was they done lol. long story short, yes it will go off and the thermal efficiancy will drop.

    You should keep AS5 in the freezer it'll last longer because its made with mayo, hehe

    but seriously over time thermel paste looses some of its conductive propertives, seems to get dried out from what I would guess to be the cpu/gpu changing from hot to cold so many times.

    In my experience, over time AS5 seperates into an oil and the paste. They can last longer if placed in the fridge from what I remember reading, but sitting on a shelf by the PC mine has sepperated after 6 months or so.

    just a suggestion, there is one more variant of MX-2 called TX-2 from Sunbeamtech. I use that too when I get bored with AS5 or MX-2 and it seems to be same temps as MX-2.

    hmm I never seen such thing on my AS5 left over tubes, but I store in a reasonably cool place.

    I have noticed temps getting worse the older my AS5 application was too, I just wasnt sure if I was the only one. Thanks newtekie you confirmed my suspicion.

    w00t, some real world proof... AS5 needs to be replaced every 4-6 months to continue to be effective. After that it slowly starts to lose its umphf..

    i've noticed older AS5 tends to dry up when in use. its looks all hard and flaky when you take the heatsink off.

    agreed with mussels, when I used it years back, I noticed that two after roughly 14 months. I use MX-2 or IC7 *using IC7 right now and this stuff is awesome*. One thing I complain about is the AS5 tube is supposed to keep air out but it looks to me like it has a way in.

    Also you said your pc idles around 60-62C but then its load of 50c? Did you mean 40-42c?

    If you all have the same results , this indicates that your CPU or cooler is not flat !!

    I always do lapping , and i use a very small quantity of paste , that is so small , that does not change to any form , one transparent film , cannot be converted to water and sand .

    You all do a major mistake at the installation of the paste .

    I use only the 1/4 of the size, of one bean of rice.

    Or the results show that the thermal paste is shite. Also thats a pretty big assumption that we're all wrong and your right. How do you know how we apply thermal paste ?

    By judging from your words ... possibly with the spoon .
