CPU temp

Thordon

My cpu runs at 50 degrees idle, and seems to top out at 63 degrees running prime95, Im using the stock heatsink/fan, processor is running at stock speed, no case fans, PSU has 2 fans on it.

Is this too high? If it is, how urgent of a problem is it? Would adding one or two case fans help a lot, or would I be better off getting a new heatsink/fan?

Pacifico

Hmm seams a little hot alright. I've the same processor and it runs at 37 Idle (While typing this ) and about 45 load.

What HSF have you got?

Billy Kovachy

I think that below 45c is good 45 to 55 running hot and 55 upwards is unsafe for your cpu.And yes you should get a heatsink/fan i would maybe suggest a thermalright and a papst fan hitide.ie has them .Try and go to the amd home page and check the optimal temp for the chip.

Ciaran500

What system temps you getting? You will probably need a case fan.

Thordon

System temp tops out at about 40 degrees

Ive an AMD 2800 and id the same problem. when i 1st got the pc it would run at temperatures of 41-54max then 8months or so later it changed to 45-61. Wanna know how i fixed it? I put the the hoover piece up to the processor cooling fan(while the pc was off) and sucked all of the dust and wat ever else was in it straight out. And now im running at 41-50max. Its was just the build up of dust that was my problem although all i could see was dust on the fan blades i knew i could at least get rid of that and who would of guessed it worked. Give it a go and dont get scared if the fan begins to rotate at scary speeds as the suction from the hoover causes it to do so.

P.S my case temperature has always rarely gone above 29* so your case temperature has only slight effects on you cpu temperature unless your case temp is really high and u have your case beside a radiator or something

i wouldnt worry about temps unless you plan to overclock or your system is unstable
the temp reading is never totaly accurate

Most chips can take a 100 so doing ok.

Em no chip takes 100c safely. 50c-60c is about the max safe temp for most modern processors if you want them to be stable and last more than a few months.

no most processors can do 140* stable

So I overstated it a bit, but nothing to worry about at these temps, tunneling etc. not likely to happen at that temp...at least not when we designed stuff...a long...long time ago

Hello Thordon it's good to see that you got your PC back up and running! Did Komplett replace the lot (MB + CPU) or just the MB?.....Do you remember when I saw your case and heatsink and I told you that cases, PSU, heatsinks, and fans were all important components of a PC and you weren't really convinced.

Well now do you believe me I'm sitting in front of an Athlon 2800+ clocked at 2322 Sandra is trying to warm it up a bit by running it's Burn-In tests....it's sitting at 37C it can go as high as 41C when it gets really stressed at idle it's around 31C; before any one asks ,yes, I have disabled Cool and Quiet since it's not really needed :cool: The system hits 29/31 and the hard drive is at 18/25 idle/defragging. The difference between our two systems is that I got a cheap MB (it's the cheapest S754 you can get it's limiting my OC else my 2800 would hit 2400Mhz stable) and CPU (the 2800) but I got a good case, PSU, heatsink and fans. This rig is faster, quieter, cooler looking (if you are still using that case I saw when I was around) and has far lower temps. I've not OCed the Gfx card yet but my initial 3D Mark 2001 score is 20572; I may hit 21.5k or higher when I OC the Gfx card (9800 Pro flashed to XT).

Moral: Forget the Mhz, cool your PC and you can OC back those "lost" Mhz

I've got an XP2500+ (at stock settings) which runs at round 65-70ºC most of the time. Its around 18 months old, no problems yet.

At the moment I've got it slowed down to run at 1GHz (don't ask why) and its still at 54º.

- As everyone knows, smoke is captured inside the chip when it is made. Its the smoke that makes the chip work and when the smoke escapes, the chip is fùcked.

Most chips can take a 100 so doing ok.

As has been said most AMD chips can take around 65 ish mark before damage can occur. I imagine its a bit higher as im sure they are giving themselves some leeway (AMD that is).

63 is ok but i wouldnt want it going much higher (my old XP topped out at about 65 after i damaged the HSF and ran fine for over 6 months before i replaced it. It is still running fine now but has much less use and runs a bit cooler).

Thordon

Did Komplett replace the lot (MB + CPU) or just the MB?

Neither, they didnt find any faults, the only possible reason I can think that it didnt work was that it was sitting on foam, and after reading around I found that some foams are conductive.

I'm sitting in front of an Athlon 2800+

I thought you were going to wait for 939?

I told you that cases, PSU, heatsinks, and fans were all important components of a PC and you weren't really convinced

I wasnt planning to overclock, I didnt think the stock cooler would be insufficient. By the way, I used the thermal paste this time (used thermal pad before).

if you are still using that case I saw when I was around

I am yeah, I had the case already and it was being unused, ill probably get a new case later on. Cool looking cases are nice and all, but I prefer to look at the monitor tbh

Forget the Mhz, cool your PC and you can OC back those "lost" Mhz

So you think I should underclock a bit and when I get better cooling, I can get that back?

Stock cooling is crap, never use it and so are thermal pads

Good cases look better and cool better aswell and are just better to work with.

Get better cooling and spend less on the processor so therefore you can OC it to the speeds of a higher processor using the better cooling Meanwhile I've had to tone down my OC to 2277Mhz but on the other hand my 3d Mark01 is now 20996 (so close!!!) Once I OC the Gfx card I may hit 22k Damn my rubbish MB.....it wont let my cheapo RAM go over 253Mhz

Nice going so far . Why not use dividers so you arent depending on your Ram being stable? What memory did you get anyway, doesent seem bad if its getting to 253mhz!!

I take it you got the Chaintech mobo? How do you find it, what are its majour downfalls........ it doesent look like a bad option if its getting you over 2.3ghz (500mhz overclock) and its pretty cheap!!

While Im at it, I may as well get at least 1 case fan and maybe a heatspreader for my 1 stick of ram (in sig), any recommendations?

Thanks for all the advice everyone

Col_Loki

Pop in a case fan or two and you will see a very big temp decrease. You should also get a decent overclock while keeping the temps down........ its free MHZ.

The MB is rubbish so I can only push the HTT to 258 before the board loses it (this is with low mutiplier and HT speed and RAM at 133Mhz) So if I were to use multies the RAM would be at 215Mhz (166 - 6/5 divider) so while my CPU core would be higher my RAM would be well under it best clock rate. So I'm running it 1:1 with RAM as high as it can go (just 5-6 Mhz from the max HTT of the board) I think the Athlon 64 gets the most out high clocked RAM then high core clock, but I will try a divider (166) OC later on today with tight timings and I'll see which benches best; high RAM or high core, I can only have one.

Col_Loki wrote:

The one you recommended the very cheap MDT RAM of course it can only reach those clocks because of the very loose timings of 3-3-3-9 (Yes CAS 3 latency but I think the extra Mhz this allows in the OC make up for the latency)

Yes it is very cheap but the one I got was even cheaper, yep the Asrock, it's a bad board because I know this chip can go over 2.4Ghz; but the board is keeping me back :mad:, the voltage options are non-existant the V-core is now at it's max allowable setting of 1.550.....the chip could do soooo much more if I could increase the voltage to the LDT (in charge of HTT speeds which are holding me back!!!!) I wish I cold hit 300 HTT because the chip can do it, for €70 though what can you expect! I'm very happy with the rig now I'm going to OC the core to it's max and tighten the timings to see what I bench If only I could increase the Vdimm and LDT voltages.......

That's the Heatsink I have in my rig and the same thermal paste aswell - so far so good , as for Papst fans.....I only have one and I don't think it's quiet but I'm in the minority since lots of ppl really like them. As Col_Loki said some quite case fans should do; one intake and one out the bigger and quiter the better these are ace. Of course your case may not fit them......;)

Thordon

Ahh, this is turning out to be more expensive that I expected, jes have nice prices but high shipping, hitide have low shipping but high prices, I tried a bunch of other sources but it always comes up the better part of 100 euro, seems like a lot for a heatsink and a few fans.

Also, Im not sure the heatsink I want is compatible with my mobo:

Heatsink: http://www.thermalright.com/a_page/main_support_installation_slk948u_intelbolt.htm

Mobo: http://www.epox.nl/english/products/motherboard/8kda3.htm

I seem to need 4 mounting holes or something, which I dont seem to have , any other reccomendations?

Edit: Never mind, found a link on the thermalright site and the 948U is compatible.

BloodBath

The slk is a very good heatsink but the sp-97 only costs a little more and is the best you can get. It's the same as the slk but has 3 heatpipes.

Fair enough, I cant find it in my usual online components shops, know anyone who sells it?

Edit: Hmm, it looks like my motherboard isnt supported anyway, oh well.

Most amd cpus can run around 85-90 degrees max so I wouldn't be too worried if the temperature was around 65.

Those are Athlon XPs not Athlon 64s - anyway Thordon I know it's expensive to retrofit an old rig with better components so unless you are finding your computer unstable then I really wouldn't bother about changing the cooling; I happily ran an Athlon XP at ~60C for months on end and it never affected the computer. So do you really need to change your computer now if you don't have the cash? Is your computer crashing or unstable? If it's the heat you are worried about are you planning on still using this PC in 7 or 8 years from now?, otherwise don't worry!

GreyAlien

My bad Athlon 64's max temp is 70°C :rolleyes:

Thordon

I ordered the stuff anyway, it opens up the option to overclock, and the heatsink is compatible with 939 so I can always use it in a new rig later on.

BloodBath

That's their rated max temp. You want to run them about 10c under this to allow for changes in ambient that will affect it.

It's the same with p4's. Both the Prescott and the Northwood are rated around 70c but you wouldn't want your northwood running any more than 60c. Maybe 65c for a Prescott.

Thermal throttling will kick in if you reach or go above their max stated temps.

Actually they recommend 20 degrees under the max temp
I was just stating what their max temp was.

Aye but bugger what they recomend. 10c under is fine.

Ok I got the stuff today and installed it all, other than the case fan I bought which didnt come with nuts/bolts to mount it so I have to pick them up later. The difference in cpu temps is tiny (now its 47 degrees idle, 60 degrees load), based on reviews and posts here that seems very wrong, I must have done something wrong.

I tried the cpu fan both facing up and down, didnt make any difference. One thing Im suspicious of, is when I applied the arctic silver 5, I had to take the heatsink off because I had used the wrong sized standoffs, I didnt bother removing and reapplying the paste, could this be responsible for the dissapoininting performance?

OfflerCrocGod

Thordon wrote:

Not likely, what could be the cause though is a crappy BIOS, flash your MB to the latest. Does your case have good fans cooling it i.e. intake and outake? It could just be a bad case that keeps the hot air inside your case and keeps it nice and toasty.

it works too, my p4 was running at 67 degrees sometimes, after the hover its down at 50.

Hmm I've been wondering about this too since I built my new amd64 machine last weekend. got a sapphire ati x800 in there, two hard drives so i'm a bit worried about heat.

It's running at 49c idle, sys temp is 34c. Under load it goes up to around 52-54. It was running at 52-55 idle before i got a case fan in.

Thing is I've only got one case fan that's extracting, i have another fan but don't have enough pwr connectors to connect it. I note that on the mobo [msi k8t Neo] there's a tiny 3 pin connection for some sort of fan. Can someone point me towards one of these fans? i've space for an 80mm at the front, but it would need to be an 80 mm with one of these little connections. Komplett don't have any case fans at the mo. and peats sold me these two ones with the big pwr connector dealies, can only use one.

Thordon

Can someone point me towards one of these fans?

The case fan I mentioned is this one : http://www.jes-computer.de/product_info.php?pID=15564

Its an 80mm x 80mm x 25mm fan and I can confirm that it uses a 3 pin molex connector. That should work.

I had a 120mm one extracting hot air and a 92mm one doing the job of intake and blowing over the HDD (it's temp usually in the 20-22C range). You should have enough fans so the air flow is strong enough to move the hot air and replace it with nice fresh air, one 80mm fan may not be enough So Thordon you got your stuff from jes? how long did take for shipping and did you use Pay Pal?

So Thordon you got your stuff from jes? how long did take for shipping and did you use Pay Pal?

Yep, 4 days, and used paypal

Thordon

I just tried running the PC with one side of the case off: 36 idle, 43 load, ok, its clearly airflow (or lack of ). Once I get my case fan in (the mounting area is right by the cpu) it should help.
