OK, after a month or so of work, I have finally worked out all my software problems with my comp. I have one last problem though. The thermal paste on the heatsink has seeped in around the edges of the CPU, such that the top of the CPU has almost no paste on it. I am fairly sure that this is the reason my CPU is running 10 degrees F hot. So what I want to do is get some more thermal paste. What kind of thermal paste would you recommend, where can I get it, and how do I apply it? I don't want to overclock, so I don't need a new heatsink (unless that's the easiest way). any websites with pertinent info would be appreciated.

OK, more info.
AMD 1700+
400W power supply
ambient temp (no load): 82 degrees F
cpu temp (no load): 60 degrees C/105 degrees F (I don't understand it either)
Let me make sure I have this right. On AMDs website, they say the maximum working temperature for this CPU is 95 degrees. They don't say if that's celsius or farenheit. Which is it?

If they don't, it's celsius. All computer components usually deal with the celsius system. So, you're alright with 60°C, but it could be better (unless you have the retail HSF). Then, just make sure you have good case airflow, and you should be copasetic.

See, the problem is that my computer, after about 3 hours of use, crashes. I don't know why, but since I have a 400W power supply, I don't think it's power. Like I said, the thermal paste isn't on properly and I was thinking that the problem might be overheating. The crashes aren't software crashes (Close program dialog box, etc.)---the system just loops and must be hard reboot. So....I dunno. I have no way of checking the temperature under load, so maybe it's high enough to crash.

If that thermal paste isn't staying on, then I'd first try and get some Arctic Silver 3 or Arctic Alumina. I think the latter might be okay for you, especially since you're not overclocking. But, I quote from both of their information pages:

<font color=red>Absolute Stability
Arctic Silver 3 [or] Arctic Silver Alumina will not separate, run, migrate, or bleed.</font color=red>

A good retailer that carries this is either <A HREF="" target="_new">Newegg</A> or <A HREF="" target="_new">CrazyPC</A>. CrazyPC has the Alumina compound, while Newegg does not.

By the way, I'm asking again because this is a little more important than a good heatsink/fan combination: do you have good case airflow? When I ask this, I mean are there any case fans bring cool air from outside the case? It does no good to have an awesome HSF, but no cool air to cool down the heatsink. Plus, it'll help the components out better, too, such as the hard drive, graphics card, etc.

Hey G,

In my worthless opinion, for a XP 1700+, that is too hot. If I were you, I would get a new HSF(you never said what you have), the HSF that I would get is T.I. Dr. Thermal V77L(for non-over-clocking) or V77N for mild OC'ing(it's much louder). The Vantec CCK 6027D is also very good for quieter non OC'ing. There are better HSF's out there, but they will be much LOUDER, and cost much more.

The temp.s that you should be shooting for are less than 50 C for the cpu, non-OC'ed. At the "Maximum Working Temperture" you will have a "Minimal" working CPU lifespan....keep it cooler!

Also is that Ambient Temp, inside the Room, or inside the Case? Good Luck............oh, & that statement on the bottom, is my "Signature".

Peace Out..............tile

It would be nice if everyone gave too much information about their system & problems.

I know it's your sig. Just thought that would helpp. Anyway, I am just using the Heatsink and HSF that came with the processor, b/c I am cheap. The ambient temperature of the case the last time I checked it was 82 degrees F. That seems about the same as the rest of the house. I have pretty good case airflow (I think), but you can check me on it. One fan in front, two in back, the power supply fan (which fits the config AMD lists as preferable) and the HSF and GPU fans. I think what I'll do is just buy a new heatsink and some Arctic silver 3 if the heatsink compound I got from Radio Shack doesn't work. Like I said, I'm cheap.

Dangit, GeoVince...switch to Celsius!!! :lol: 

Ambient temp of 82°F/27.78°C isn't too bad. I guess it's pretty hot around there. If it is, then you might not have a choice but to get a better heatsink, <b>or</b> get better thermal compound. Something from Radio Shack wouldn't be as good as AS. If you're low on cash, don't get AS3, but Alumina instead. You're not overclocking, so that's what I'd recommend.

If you want a low-cost heatsink that performs fairly well up to XP2100+, I'd recommend a ThermalTake Volcano 6Cu (<b>not the plus version...those are screamers!</b>) <A HREF="" target="_new">At Newegg, it's 11 bucks plus 6 bucks shipping.</A>

If you need to convert temps, refer to this page: <A HREF="" target="_new"> Temperature Conversion</A>

I know, I know. I shouldn't use farenheit. Bad habit of mine. Well, regardless of what you say, I am going to try the radio shack stuff, just because I already bought it. Chances are it won't work, and then I'll buy the AS3 and a new heatsink. If I am going to spring for the 6 bucks shipping I may as well get the AS3. I'll post later tonight and let you know if it worked.

i can vouch for the volcano6cu...
and i can also confirm the fact that the cu+ is a SCREAMER!
i have the cu in mine, and my friend has the cu+ in his...he got it thinking he would run cooler...(by like 1 degree when i am running stock voltage).
BUT, when he runs his system, it is AT LEAST twice as loud...
even if i turn EVERY fan in my case up ALL THE WAY, i am STILL not quite as loud as him with just the 6CU+ in there...
SO, i can say for a fact that the CU+ is not really a great way to go...
the CU is however...and it is really quite cheap! :smile:

Alright, I didn't put on the new TIM...I am having some concerns. The temperature seems completely normal (40 degrees C) under no load (I was reading it wrong before...grrr...). Since it is normal, I don't know why my comp is crashing, but it seems like a heating problem. Where can I get a utility that can interface with the bios and give me temperature readings, or even better, output them to a file so I can see what the temp was when it crashed? My mobo is an ABIT KG7-RAID which is AMD 761 based (north bridge).

hehe i just ordered the plus version, awaiting it with the rest of my computer parts. Screamer? How bad is it? Can i turn it down?
May 15, 2002 8:30:06 PM

Aw got the plus? Oh well, nothing you can do about it now. I hope you can handle it. If Dave says it's twice as loud as the standard 6Cu, then it might be pretty loud. And no, I don't think you can turn it down without doing a wire mod. But, I think that defeats the purpose of it fulfilling its duty as a Volcano 6Cu. :eek:

well, if he doesnt sleep in there...i guess it is ok...
although i have slept in my room when my friends computer was here, and is LOUD...but you could get used to it i guess... turn it down, i would say that you would want to...and to do it, i would say put a rheostat in there, and then turn it down until it is quieter...NOT TOO MUCH, because that will cause overheating problems most likely.
you could turn the fan down until it is spinning the same as the normal CU. i think that is 5000rpm? i think it says 4500, but in my bios, it says 5000...
the cu+ is loud....but i think you might live...hehe...
there isnt any way to return the CU+?

from an online ordering place w/ a restocking fee? no, not really :) . Meh it wasn't that much, if it's really terrible i can replace it. :'( 
May 15, 2002 9:29:06 PM

ah...i see....ok...
well, try it might not mind...hehe...i dunno...

Thanks villarin. I will look into that, although the heating doesn't seem to be the problem. I am looking into the possibility of a poor connection on the mobo....I have my reasons, I won't go into them here. In case anyone's curious, I will post when I solve it..excuse me, IF I solve it =]

May 16, 2002 6:59:11 PM

I'm stumped right now. Help Toey!!!

Post back if you figure it out, because it's always nice to learn new problem solving techniques. Good luck! :smile:
