AMD stock heat sink causing crashes

[Superself]

ok, I've stuck with this hs for a while now and it must be giving up....I'm blue screening when I put a heavy load on my Athlon xp 2000+ no OC.

My cpu temps got up to 80c and caused a blue screen on me....computer shut down 4 sec after.

This happens whenever I play Op Flashpoint or Battlefield.

I don't have an AC in the room with the PC, and it would be next to impossible to get one in there. I do have a heavy duty fan blowing air all over the place in my room which is about 80F.

So, I'm considering a new heat sink to help lower the temps a bit under load. I've been reading a lot of praise for the Sk-7 and really am leaning toward it. It is about time I stop using the stock hs provided and go for something with a bit better cooling.

Oh, I have a lian li 68....so air flow isn't a problem within the case.

Hm. If you have no A/C in the room, you might wanna go for the biggest, baddest HSF you can find.

The SLK900U is basically a SK7 that can take a 92mm fan. Recommended for your situation if it can fit on your mobo.

I suspect your heatsink is on backwards. Check your installation against Figure 13 of this guide. Also, if you have a shim between your CPU and heatsink, remove it.

If your heatsink has to be removed, you'll need to renew the thermal material between the heatsink and the CPU core. The stock pad is good for one use. Get some high-quality thermal grease such as one of the Arctic Silver flavors (Alumina would be fine), scrape off all of the old thermal patch, and use thermal grease.

If you've already removed your heatsink in the past, then that may be exactly the problem... your thermal patch was used up and not replaced.

My heatsink isn't on backwards. I've seen that situation before and corrected it.

The rise in temps are due to the hotter weather outside. Before we started getting in the 90s and above, the stock hsf did OK...not bad. I don't think it is designed to handle my room conditions with the room temperature being a bit above normal.

So, I'll try the biggest baddest on the block as suggested and get some arctic silver...hopefully this will help to lower my temps.


thanks for the suggestions!

If the SLK-900U ends up being either a fit problem or too expensive, then do consider the SK-7 as well. Paired up with a medium-output 80mm fan such as a YS Tech adjustable-RPM fan (moves up to ~50cfm), it would also perform pretty darn well.

If your heatsink is mounted properly and you are using some sort of thermal material, your CPU will not hit 80C. Either you have the heatsink installed incorrectly, or the temperature sensor is incorrect. Is the fan spinning?

 

[lenjack]

I agree. You cannot hit 80 un o/c'ed unless there is a problem with the hs mounting or with the thermal interface.

I don't know... Pally XP2000+ @ 100% load with 80 degree ambients? I'm not saying 80c is right but I bet that thing is still pretty frickin hot, maybe hot enough to BSOD.

What's the case temperature? This situation is exactly why I did a few mods, and am now moving cases.
With good airflow in the front and out the top-rear, you'll be alright. The stock HSF is noisy, but does the job very well.

IME (I'm in middle Georgia, that weather is here now), the CPU will rise and peak, then the case temp will rise, and of course bring the CPU with it. I don't know about no AC, though--I had to move out of my room a few summers due to the heat, even though there was central air and a window unit.
As of now, over a week into messing with it, it will run OK. I can't tell you exactly how to do it, since I am getting there by trial and error (a good case is a start, but that requires at least $60).

Here is a potentially really stupid question for you Superself: did you remember to remove the little plastic cover from the TIM pad on the PIB heatsink? No insult intended, just trying to make sure all the bases are covered...

That's what I was going to suggest, darn you!
Yeah, 80C is WAY too hot, and that's most likely from the motherboard's thermistor, so the CPU core is actually far hotter. The stock cooler should definitely keep the reading below 60C, if not below 50C.
You said the room is about 80F (26.67C)? That's not really too hot; an adequately ventilated case should handle that just fine.

Maybe a new CPU cooler would help, but it seems that it must be something other, or else the room itself has exceeded like 130F now.
How many case fans do you have, and where are they placed?

What were the CPU temps before the warmer weather came?

Well I didn't have this problem b4 it started getting hot outside. I installed the cpu and stock hsf back in November and I got ok temps (50c - 58c).

Now the board temp reads 46c and the cpu read 78.8c when it last crashed (Sunday).

I think it may be hotter than 80F in this room too.

Yes, the cpu fan is spinning....and I did remove the cover from the thermal paste on the bottom of the hsf when I installed it.

Well if you do buy one dont buy it there! Right now http://www.case-mod.com has a good deal on the thermalright sk7,sk800,sk900. and if they go off sale before you click the link svc usally has good prices for heat sinks.

If cpu temp has gone up like 30C in a short period of time, it would normally suggest either a fault with the fan or an overclock. If it took a long time its possible the goop had dried up or the heatink got *really* clogged with dust, but tbh finger points at the fan. it may be spinning, but how quickly? you can quickly check for a bizarre accidental overclock by looking in the bios, or from windows with wcpuid. 46c is really high for the case temp too, take the side door off and see what happens.

having said that, i cant beleive how cheap the SLK-700 and 900 are on that page, the 900 is >£50 here (USD$83), though i think youll need some goop (artic silver 3, $6) and a fan (the panaflo L1A listed there $3.75 a nice choice). a new heatsink purchase shouldnt be necessary though.

This is why it took me a week to get my new (old) case doing well.
Lemme guess, on a cold boot, your case temp starts around 30C and CPU around, oh, 40.
By the time you can read it in windows, you're around 30/45 )or somewhere still safe), and after sitting for 5 minutes more, it's going to 45/60 or above. Am I right? If so, give us your case model and how you have fans installed in it.

Case is a Lian Li pc 68....two fans sucking air in on the front bottom...on rear exhaust fan blowing it out. Blow hole in the top blowing air out.

Interesting thing is that now it seems that my bios is trashed...yet the pc still boots into windows. I can hit delete to enter bios, however when I get there it is garbled and locks up. Can I just flash it to fix?

I just noticed that a fan on my MB has died...dunno which one it is yet though.

Try running the PC w/ the side of the case off? More than 35C (and I wouldn't run with that) case temp in the summer is just too hot.

If you aren't running so hot...get the BIOS flash ready on a disk, l;et the PC sit for a few minutes to cool off, then do it.

ew...fan cooled chipset.
