Wow.. My processor was idling at 85c

[kirbymixmasta]

I was just browsing through sites not gaming or anything. And my comp temperature seems to be fine. I came back an hour later, unhibernated. And an alert comes up that my cpu is at 85c. I'm just thinking how impossible this is. So I download MBM5(i was using speed fan) and it says 85c. So I just shut off my computer and opened it up, and I take off my processer fan and felt the heatsink. Oh man it was burning.. so anyone have any idea how this could have happened? My processor was running at 50-60 last time i remember. Oh right heres my specs
Athlon XP 3000+
Geforce 5200 128
Asus A7N8X-LA
1 gig pc2700(no idea of the brand half of this computer was from my old hp)
350W PS.

did you use any thermal paste? my friend built his computer before and never ever put in any thermal paste. luckily, he was running a mobile xp, so it idled at 55C. after putting in some AS5, temps idled at 22C @ stock speeds.

I'm trying to get my dad to take me to Fry's. I'm looking to get rid of my stock heatsink/fan and also buy some thermal paste. But I find it weird of the sudden jump of temperature so I'm kinda worried.

The fan died?

That can't be, since the heatsink was hot. If there was not sufficient contact, the heatsink would be rather cool.

My suggestion: clean out the heatsink, likely dust and other crap is clogging it up. Also check to make sure the fan spins.

The retail AMD heatsink has a phase-change thermal pad. If you installed it correctly, the thermal pad is almost as good as thermal goop, and won't run. AMD ONLY warrants their retail CPU's if you use the stock HSF with the pad.

Check that the fan is running.

Touch the heatsink. Is it hot? Could be bad temp sensor.

 

[The Pentium Guy]

Heh. Not using thermal paste/pad = dumb mistake

 

[alexXx]

either the fan is not functioning properly, or the heatsink is full of dust , or the heatsink have lost contact with the cpu for whatever reason

Ok I got my dad to take me to Frys today. I got a bottle of Artic Silver 5 and an Aerocool 2 Fan+Heatsink. I applied it and installed the new heatsink and fan. Afters startup my computer runs at about 55. After I left my computer on for about 2 hours I would be at around 63, but sometimes it will jump up to 66-67. I undusted my fans, moved all my cords so airflow isn't blocked. I have a total of 5 case fans. 1 window, 2 back, 2 front. The window and the backs are blowing out of the case. The 2 front are pulling air into the case. Can anyone recommend how I can further lower the temperature of my CPU? My case runs at about 37-40c.
edit: Oh after I took off my stock heatsink, the thermal paste job looked really bad. So that may have caused the huge overheat. But I'm still running far past what I was hoping.

Ensure that the Asus Q-Fan feature is disabled in your motherboard's BIOS menus, if so equipped. Also, is your computer out in open air or is it cooped up in an enclosed space?

Also: third and fourth photos on this page could be worth a double-check.

It's not really cramped up, one side is against a desk, but i leave the fan so that its not blocked. And the other side its the open space of my room up till the door which is open. And I just checked the heatsink and it's in place. And q-fan isn't in my bios =/. This computer was originally hp built so I realize that I can't do much in my bios(oc and such). But I didn't see anything about q-fan anyway.

Try popping open the side panel and see if that helps. If it does, then it's clearly a case airflow problem.

I just opened it. The temp doesn't seem to be changing much. Maybe 1c. Not sure its changing between 64-66 alot.
edit: Does anyone know how to make my cpu fan blow out instead of sucking in? Vanctec Aerocool 2 Socket A.

 

[The Pentium Guy]

Technically it's "Blowing in" and "Sucking out", but blowing the air in is generally better.

Also, you DID put a drop of AS5 right? Less is always better than more. If you take out the heatsink you should be able to see the AS5 and it should be thin. But remember, when you take it out you introduce air into the compound and that causes temps to go worse, so you'll need to do some cleaning with Isopropol alcohol/Lintfree wipes once you're done.

I'll go try that.

Just went and took off the heatsink, took off the old as5 and put just a drop on. Spread it with a razor, reattached the heatsink. And i just started up. The temp seems to be a little lower. 61c, but jumping up to 63 on occasion. My case temp seems to be al ittle higher now. Its up to 43c.

Damn, I envy you... Doing that for my procs would be atleast a 1 - 2 hour project... Wow. Swapping out heatsinks / fans took about 3 - 4 hours... It sucked... Otherwise I would try the AS5.

Why? It's simple isn't it? Taking out my heatsink takes like.. a minute..? Just push down on both ends and it comes off. Take off your processor, wipe it clean with the alchohol. Put on some new as5, spread it with a razor, put it on the socket. Reattached the heatsinks.
haha sorry I didn't see your computer till just now. I can see why it would take so long.

 

[Fullmetal Chocobo]

That is one thing I miss about "standard" procs. They are so much easier to take off and on. Seems like they made the mounts for the Xeons to be a fvcking pain in the ass. Although, granted, they can support like 10X the weight of a P4 mobo. Take the good with the bad I guess... Oh well.

Let me just get confirmation that you grasped the concept of those photos: SocketA heatsinks are asymmetrical and can be installed 180° backwards by the unwary

Well I was actually looking at this alot the first time I put my heatsink on. And to me it looked like both sides were stepped. But I tried putting it on one way, and it required alot of force and wouldn't clip onto the 2nd side. So I tried the other way, and it clipped with just a moderate amount of force. So I've kinda stuck it at that side because the otherside I'd probably crush my processor before I could attach it.

 

[mechBgon]

Ok, lesson #2: not only is the heatsink asymmetrical, so is the clip. If it has a clip with a pressure point, then the pressure point will be offset, and it must coincide with the location of the CPU core. So double-check the orientation of the heatsink and the clip. The downforce of the clip may seem pretty high, but it needs to be installed the right way around.

I'm going to sleep now, but I'll do this first thing in the morning and post back. Thanks for the help.
