AMD users....keepin' Cool?

[dmw16]

I am currently using an AMD 900Mhz T-Bird and I am having SERIOUS heat issues. We are talking a 900 underclocked to 810 running over 50C. I dont really know what is going on. I think it is related to the thermal grease Im using. I am using that white stuff, it has a conductivity of .7w/m and the grey stuff I had before and have ordered again is 2.73w/m. So I think that is the problem, right now I have an alpha heatsink and a sunon fan, but I ordered a Delta fan, so that should help. Any other suggestions.
thanks,

Is the heasink making contact with the CPUs core?

make sure that the clip isnt backwards...sometimes people mmistakenly attach the clip backwards and it doesnt apply the pressure on the core just outside of the core. happened to a few people i know, they were getting temps of almost 60!! im using an fop32 with greyish coloered thermal grease(not sure the brand) and its at ~27 idle and 40 under extreme stress, and thats a 900 at 1050 10x105

well, if you are in the market for a new case and have some cash to spend, i would highly suggest the THEON Cyclone 5000 Ultra case.

hope that helps.

Bah! That case has a million fans and it probably loud as hell. It's not necessary to substitute fans for poor HSF application. Plus, I think the obsession with low CPU temps is getting out of hand. As long as it is a reasonable heat (around 40 c) it should be fine. AMD rates these CPUs as withstanding high temps. Sure, a few degrees cooler will get your another year of CPU life, but we are talking about say 5 years vs 6 years. Who is going to be using this CPU for that long??

Havoc...of course...but now u're destroying the self-integrity of these hardcore o/c'ers..
i mean, the 1 degree F makes a diff.

that's an extra 2 hours of cpu life.

50C underclocked it pretty hot tho...guaranteed you've improperly attached the HSF, or your HSF is crap...although it sounds decent...

what exact alpha heatsink are u using?

ANY thermal compound should be good enough to make relatively good contact between heatsink and cpu, unless the heatsink is malformed or something...warped or non-lapped, etc..(or are u using white wood glue by accident?)

worse case scenario - buy a new HSF combo (i.e. FOP38)

Also remember that you only need a tiny bit of heat sink compound! Just enough to cover the surface and fill the gaps between the heatsink and the core.

What i do is put quite a bit of heat sink compound, (the normal white stuff you get from radioshack/Tandy's) then with a tissue start spreading it all over the surface of the heatsink and wipe of the excess. By the end of it the shiny heatsink surface has a dull white haze over it, but the metal underneath can be still seen.

Before i clip the heatsink to the chip (i have a coolmaster DP5-6H51, with the thermal pad removed, on a duron 800), i just sit the heatsink on the chip lightly and move it back and forth and then clip it on.

I haven't seen it it reach over 45C yet, with the room temperature in the high 30's (summer here with no air con)

With heat sink compound more, is not better!

the case is actually not that loud at all...

If a 900 T-Bird is averaging 50C while underclocked to 810MHz there's far more wrong than poorly applied thermal compound. I agree that it definitely sounds like the heatsink is not properly attached to the cpu. I have a Duron 700 running at 1083MHz and my temp generally hovers around 38C.

Doesn't the A7V have serious problems measuring temps?

 

[Soccerman]

mind running a bit RC5 with those speedy chips you guys have? I'm blown away by the untapped power going through these forums..

Enough with the propaganda allready!
