Computer hot as a mofo

i just recently installed a p4 3.2 prescott. it's not oced right now.i did oc it to 3.4 a few days ago. and the temps were fine. but i put everything back to default settings and now my computer is hot as hell! my cpu is idling @ 47C right now! it crashes in games too. at least now it's no longer a video problem.

and yes, i put on arctic silver on my cpu. i have a thermalright sp 94 with a 92" tornado. even with the tornado turned on full (5000 rpm), i idle @ 47. and i'm not even ocing!

wtf?

and just 2 days ago i was ripping 4 dvds to xvid all night, and it didn't crash or anything. my temps went up to 56C that night, and it didn't crash. why is it crashing on games now?


:pinch: :pinch: :pinch:

I would double check your "default" settings.

well, my bios is set to "default factory settings"

and my clock settings are set to standard. i look in the hardware monitor, and everything is the right clock. my 3.2 shows up as 16 x 200, cpu's voltage is 1.4v. graphx card isn't oced either

Also double check the heatsink installation.

What case cooling do you have?

my case:
1 80mm intake on the side
2 80mm exhaust in the back
i'm pretty sure these don't spin faster than 1500 rpm. they're basic case fans that came with my case


i should check my heatsink. i did play around with it back when i was fixing my video card problem. i took out my 2.4, and ran some tests. then i put in my 3.2 and ran some tests. i also had to flash my bios to a newer version for my mobo to work with this 3.2 prescott with 1mb L2 cache

well i know intel's chips run hot, but this sounds a lil extreme.......

what other heat sources do you have?
how is the airflow? is there anything restricting it?

try leaving you comp off for a while to cool down, then start it and boot into the bios, what are your readings there?

how thick was the arctic silver layer?

EDIT: why do you believe your fans dont run faster than 1500rpm?

there should be nothing restricting air flow.

as for the arctic silver, i put a tiny dab in the middle of the cpu and let the heatsink flatten it as i screw the hs in

You should spread the AS out into a thin layer, like it says in the instructions. :rolleyes:

Putting a dab in the middle does not ensure that it spreads evenly across the HS, so half of your cpu may have very poor contact with it.

someone here told me to just put a dab in the middle, and screw the 4 screws of the hs diagonally.

i guess i should go take a look again

I called AMD one time and they gave me the same advice. Push out enough arctic silver so that it'll be the same size as a grain of rice and then just push it down with the heatsink.

Yeah but it's an Intel CPU.

so is there a difference?? thermal paste should be a thin layer that covers most if not all of the cpu metal surface.

btw, my cpu's still hot. its idling @ 44C right now. i didn't make any adjustments to it though. i should soon

There's a very big difference between AMD and Intel cpu construction.

The AMD cpu's your scenario refers to had no heat spreader, so the small dab of AS would almost certainly spread out to cover the chip. In comparison, Intel chips have a heat spreader which makes the potential surface contact about 8 times as large. A rice grain sized dab which would be sufficient for the old AMD cpus would not be enough for a P4 cpu, which probably explains the problem.

Athlon 64 chips have a heat spreader though, and need more compound.

oh i see
i'll look into it tomorrow

You could always remove the IHS from your chip.
I'm seriously considering doing just that during my next waterblock swap.

IHS = The Heat Spreader?

it's the big metal thingy on the cpu that covers the actual chip. removing it helps heat conduction directly to the hs.

i'm not sure i want to. i might sell this cpu

Ya I was just wondering what IHS stands for.

it probably literally means Internal Heat Sink

:01:


a little update: computer's still hot like a mofo. my tornado is spinning @ 5000 rpm rite now,a nd i'm idling @ 46C!!!

but at least my games have stopped crashing. :w00t:

Does the heatsink feel cool?

If it's cool then the problem is the heat transfer form the CPU to the heatsink.

If the heatsink feels really hot then you've got more serious problems.

good point! thanks!
i'll shut down later and try it

You should probably have teh comp on when you go to feel it, or the heat sink might have cooled off by the time you touch it.

ok, i just felt it. it's idling @ 49C right now. i just put my finger on the hs. it does not feel like 49C. 49C should feel almost burning on your skin. my hdd1 is running @ 50C right now. i put my finger on that and it feels considerably hotter.

so i guess this means i gotta take it apart again. sigh

You say it doesn't feel like 49C. What does it feel like?

it feels 30-40C

IHS= Integrated Heat Spreader.
They are soldered onto Intel chips and not removable.
AMD uses a type of silicon gasketing which can be cut and the spreader popped off.
As my workhorse Winnie 3500 approaches obsolesence (they are currently going for @$125-150 in classifieds) I'm increasingly tempted to perform the radical spreaderectomy on it and see what happens.
This may be the last gen of AMDs with this "floating" IHS mount (rumor has it that they will adopt the permanent Intel method) so my window of opportunity is rapidly closing.

Why suggest it to abu then?

Because I'm an idiot.


@Abu....nevermind.

i just took a look at it last night. took out the hs. felt it, and it felt just as hot as the cpu (i did this within 5 min of turning my computer off).

i removed the hs, cleaned the paste, reapplied arctic silver, and my temps are still the same. 47C idle and up to 59C load (@ full speed of my tornado, 44C idle and 55C max load)

wtf??

Is it possible that the heatsink is installed backwards?

To feel the CPU after you take the cooler off is way too late. It's a small lightweight item that cools quickly and doesn't retain heat.

the hs is definitely not on backwards. my old cpu (2.4c) used this hs, and it's temps never went over 45C in the summer. and it was oced to 3.2

It must be something that prevents the heat from transfering to the heatsink.

that can't be possible. unless arctic silver has an expire date hmm

valid or not, i did this. took it off. felt the cpu (with the paste still on it) and the hs at the same time. and this was within 5 min after i shut down my computer. both felt the same temperature.

i'm thinking this is a problem with the cpu. when i first installed it, it was fairly hot. the 1st time i popped it in, it idled @ 40C ish. i oced it to 3.4, just to see how well this cpu oc's, and it bounced around from 40-43C. load was just over 50, and i didn't like that. so i set it back down to default clock settings. now the temp just won't go down.

right now, my tornado's running full speed (4990 rpm), and i'm idling @ 47C. sigh

i'm thinking of selling this and going back to my 2.4c. the 3.2 i got is a 1MB L2 cache prescott. so it's worth around $200 on ebay. i got it from my uncle, so i guess i could put the $$ towards the small form factor i'm building in the summer.

Yes. I don't know what else to add.

i was wondering. how does my 9800 pro's performance match with the 6600gt?

as of now, i can spare $200 to fix this computer. then sell everything to get part of this $200 back when i build my new computer.

i can get a 6600gt for around $120-$130, or i can spend $180 and get a 6800. i need agp cuz my mobo doesn't have pci-e. hmmmmmmm

i might also need some $ to get a new psu. hmmmm

6800's are way better than 6600's, but don't waste your money getting another AGP card.
Save the cash for your new PC.

it's not my cash i'm spending. hehee

and i think i posted this in the wrong thread. all that's supposed to go in the video card thread. oy

i just took out my 3.2 and popped in my 2.4c. my temps dropped by 20C! i'm now idling @ 37C, and my load is 44C. lol
