What's a safe system/CPU temperature?

[fmctm1sw]

This taken at 22:55 (just now)



On the up; 60°c as I type, I'll try encoding, see what happens.
Thanks for the tips on a fix.
Will


EDIT 61°c : only have IE running, gone up 6°c in five minutes


EDIT2: only two minutes into encoding temp up to 67°c

That's a lot of heat Will. I thought mine was bad... I think at 74 you may be heading for CPU breakdown.

I have a pretty good case, it's the Cheiftec scorpio.



What do I need to do folks, I can't see how a 3rd fan will help


I am using the supplied AMD heat sink and fan, but have no paste.
I've had this XP2000 for an age now and never had anything like this before.
Will

That Chieftec case looks almost identical to mine. Like flaninacupboard has mentioned, you must use thermal paste. It's not optional. Stock CPU coolers usually work pretty well, so I think the paste will improve things a great deal.

In my case, I have the two rear 80mm exhaust fans, another 80mm fan in the case door that is blowing nearly right on the CPU, and a 500W power supply that has yet two more fans... a 120mm on the bottom of the supply (right above the CPU) and the usual 80mm rear exhaust fan. The 120mm bottom fan blows through the power supply, sucking even more warm air away from the CPU. I have no fans in the front. That functions as unrestricted fresh air intake.

Like I said, my case is the same style as yours, and even on very hot days I've never seen my CPU go above 40 celsius. It idles at 28-30 degrees and runs at 33-34 when used lightly, 36-38 when pushed hard.

40 C Case temp, 55 C CPU. The damm room temp is 28 C

Get that heatsink on properly Hay

Well, that's your problem. Go out and get some paste or get the 2 way tape version of the paste. Ever way, you need to get that heatsink put on properly


EDIT,

Get that heatsink on properly Hay

What he said

[gshelley61]

Sorry... I'm an idiot.

OK -

Case temp 30

CPU temp 46

Earlier posts were from (bad) memory.

Still, 74 is way too high, Hay

[Will Hay]

Thanks folks

I have two 80mm fans in the back and will be applying some paste tonight a pal of mine has.
He also has a bigger CPU fan so I'll install that too.
He asked if I'd installed the fans the right way around, I didn't know there was a right way and a wrong way
What I don't understand is why I'd have these problems now, when my system has been exactly the same for a year or so (other than a replacment HDD this week).
I guess it's the new HDD, or perhaps I've disturbed something somehow, but I doubt it

Still, 74 is way too high, Hay

Yeah, I know shelley, it's a bugger.

[flaninacupboard]

may seem a silly question, but have you looked to check the CPU fan is spinning? could be a power cable has got stuck in there, or maybe an IDE cable is covering it?

[Will Hay]

Hello

may seem a silly question, but have you looked to check the CPU fan is spinning? could be a power cable has got stuck in there, or maybe an IDE cable is covering it?

Not such a silly question but no, I haven't.
Reason being, the BIOS reported it as spinning at x rpm so I didn't bother.
I'll visibly check tonight, thanks
Will



EDIT: At home as I type, one of the two 80mm fans wasn't spinning (I'd forgotton to power it up!), at 52°c at the moment (after five mins usage)
I'm gonna the leave PC until I go back to work, I'll re-post final temp. after half an hour usage (ripping a DVD as a test).
The fan that wasn't running is aimed directly at the primary HDD, so I'm thinking that may well help.

EDIT2: Now at 54°c after eight minutes usage.

EDIT3: I left it running (capturing with the ADVC-100) at 13:20 having been on for forty minutes and was running at 57°c, as it had for the fifteen minutes prior (when I was ripping a disk).
I'll apply the paste tonight and fit the new fan and report back.

haha, just seen your new sig

Beats shits the bed i suppose

heheheh - he's a cheeky fecker ain't he doesn't miss a bloody thing.

speaking of CPU temps - any views of those jet type CPU heatsinks ? I am thinking of getting one for my PC.

[flaninacupboard]

like this?

logical design but probably noisy. big too, i couldn't use it - i've got about 3cm clearance from top of my fansink to my power supply.

Jesus - 3cm gap between fan and cpu ? I'm suprised the things doesn't overheat. My last case was too small and I had a similar problem with the heatsink being right next to the PSU, I had to ditch the case and get something larger.

[flaninacupboard]

yeah, i'm toying with the idea of a larger case, but this one is part way through being modded, and is easily luggable to lan parties.

it's silly, you buy a m-atx case and a m-atx motherboard, you'd expect them to work properly together....

[glockjs]

well my new puter is built. i think i went a little overboard on the cooling, but if you want a good fan try this one and use some artic silver 5.

i was testing the puter last night and haha. well, it seems to idle around 33 to 34 C. i did a stress test with prime95. under full load it went up to 46 C but after an hour and a half it went down to 42 C haha under full load the whole time. well i accidently went to sleep and hours later still under full load it stuck at 45 C. so i'd say that fan does a pretty good job..

i think i went overboard on the case fans though, 1x120mm and 2x80mm. but hey, better to run cool than hot. its a 2800+ xp from what i heard amd's like to run hot as is so i took a couple extra steps

Thermal paste installed at lunch-time, PC now averaging 48°c (rather than the 75°c earlier this week
Thanks folks, although I may have created another problem for myself now

It made THAT much difference? I may look into that...

Yup, although to clarify....

I have two 80mm case fans in my PC.
With only one fan running and no paste (as was the case this week) the PC was averaging around 65°c under normal load (ie. no encoding).
I was suffering resets at 75°c using TMPGEnc Plus (an encoder, for those of you who don't know!).

With both fans running and no paste the PC was averaging around 55°c under normal load (ie. no encoding).
I successfully encoded for two hours last night although my temp hit 68°c once encoding had finished (and despite telling TMPGEnc to shut down the comp. the thing just hung).

With both fans running and thermal paste applied (this lunch-time, Thurs) the PC was averaging around 45°c under normal load (ie. no encoding), and lifted to 48°c when I tried a quick (twenty second) encode (and then stopped the process).
I'll do some encoding tonight and post back the final temp. after the process has stopped, if anyone's interested

Thanks again folks, I'd have never have guessed the paste would have made so much difference had you all been so helpful (nor would I have checked the fans were fully operating had it not been suggested by flannin...)
Thanks again,
Will

Will,
Just so you know, some of those guys are lying.

Their temps are less than ambient, which is a big part of it.

Will has a few probs. Just what they are he doesn't quite get across

The rest of you seem not to have checked the max on your particular CPU. You just say Hey, 50 C seems like a lot. Mine is less than room temp. BS, boys.

I just decided to give a pass here, I quit, you're too dumb to comprehend.

Cheers,

George

[flaninacupboard]

george, what are you talking about? normal room temp is 20-25 degrees c, no one has quoted a temp that low, or lower than that. lowest i can see is gshelley61 at 28c.

[gshelley61]

Yes, and I had already admitted making a stupid mistake after posting my temp monitor readings from memory (I had mixed up case temps in there or something):

Sorry... I'm an idiot.

OK -

Case temp 30

CPU temp 46

A three hour encoding with TMPGEnc (nothing else running) resulted in a 55/56°c temp.

result.

you happy now, or are you still going to get a jumbo fansink?

ahhhhh, the inane ramblings of the elderly

No, I'm delighted
I just wish I could figure my friggin' keyboard problem, it's proving a bigger pain than the heat
