My CPU is cookin... Gets up to 83 or 84C in no time...
CPU will hit 57 to 60 with an open case..
Retail cpu with heatsink (properly positioned) although I didn't apply any thermal grease and just used the stuff that comes with the HS.
Skyhawk Jupiter Aluminum case with doesn't feel very warm to touch...
Could this be an erroneous reading...
What should I do?
 
Are you sure its 80c? Are you overclocking way too much? Is there too much thermal wax on the heatsink?
 
I'm not overclocking at all. By the way the system temp is around 52C. I've got a case fan blowing down on the HS fan-could this be part of the problem? If I want the fan to extract air rather than bring it in how do I reverse flow?

That alone is enough to tell me that your fans are either non-existant, or not set up correctly.

If the temp is fair with the side off, then there is a problem with expelling air from your system.


Make SURE that your fans are blowing the right way... this is usually indicated by small arrows on the casing of the fan pointing the direction the air is going. Make sure the front fans are pulling air in, and the back fans are blowing it out. If need be, remove any grates or covers that may be preventing the fans from expelling air.

Yes. It's your case fans which are causing the problem, since with the side cover off the temp drops to an acceptable level. What is your case temps btw? And how many fans and which way are they facing? If you want to reverse a fan, take it out and flip it over.
 
If your temp drops by over 20C when you open up the case, then like others have said, it must be a problem with your case fans.

How many fans do you have in your case? You will want the ones in the front to pull air into the case, and the ones in the back to pull air out.
 
time for a new hs.

I just got a retail 2400xp, and the hsf that came with it looked like a joke. I dunno, maybe it's because I've been using alpha and swifty but yea, those retail stuff looks pretty cheap. check out svc, they have some pretty good deals on hs right now

edit: yea, I know it's his case fans but 57 - 60 is still kinda high.

I disagree. That's well within safety limits. Buying another hsf if you aren't ocing or care about noise would be a waste of money. Somehow I don't think AMD would equip their retail cpu with bad hsfs.
 
Just fired up the machine after overnight cooling. First CPU reading (15 seconds after hitting the power button) is 52C. Is this kinda high?

yea thats high ive never seen my case above 30c even in the summer. im runnin a XP1700 @ 1.64GHz and teh CPU stay at about 38 runnin seti 24/7.
have a SK-6 w/ delta fan.

id make sure that HS is applied properly and apply some AS2. also make sure your case fans are workin correctly. front intake and rear exaust. 50C is rediclious for a case temp. unless you live in the Sahara
 
look, I know the max temp is about 90 for most amd cpus. some ppl just like their temps low you know. that's all i meant, didn't mean he has to get a new 1.
 
Yeah, I know about the case fans. Just got a brand new Skyhawk Aluminium Case (jupiter Model)- and the front panel has no air intake-a fan sits their behind the lower drive bays but there just isn't any visible openings in the panel. Does this mean I'm screwed?

no it dosent. and im sorry if my other post sounded mean it wasent intented to be.

teh fact that there is no ventilation in the front of your case is a problim because teh fan isnt pullin in cooler air from out side. this can be fixed eaisily. if you have a dremmel you can make a big circular hole. if you dont have a dremmel. a regular drill will work. just drill holes in the case where teh fan sits and make it look like swiss cheese. itll do the trick in a pinch. If you dont have a rear exaust fan i suggest getting one because it will greatly help pull air through the case.

and as i said before just dubble check the mounting of the Heat sink and HS fan.

O and make sure to check for dust. as its always a problim. and try and make syre the cables in the case dont obstrust airflow greatly

If your cpu temp is that high, it means one or more of the following:

1) Your heatsink ain't doing it's job. Since you said it was positioned correctly, that would mean that the clip ain't providing enough pressure or that there is something (ie dust, hair, oil from your skin, etc) in between the heatsink, thermal paste/ pad, and CPU core.

2) Your mobo might actually be read the CPU diode's temp. Some mobo's do that, and that is good, since it gives you the actual CPU temp. The reason why many other peoples temp are alot lower is that their mobos are reading the mobo's diode temp, which is usually lower than the actual CPU temp. Now, even if your mobo is the type that reads the CPU's diode temp, that is still pretty high. What is your mobo?

3) You are living in a very hot room.
 
Gigabyte 7VAXP MOBO. And no my room is not hot. I do have the case sitting in an office hutch that appears to be well ventilated. If I pull the case out of the hutch I get CPU temps of 67-68 and case temp of 45. My case also contains two cheetah scsi hard drives in additon to a WD eide drive. Should I get an aftermarket heat sink or would putting some fans in the hutch give me more ban for the buck. The case is made of aluminium and should transfer heat quite effectively?
 
If you're relying on the case material to get the heat out by passive conduction, that implies that the air inside is significantly hotter than room temperature to start with. A properly-ventilated case turns over all its air in less than 30 seconds. With proper ventilation, it doesn't matter much if the case is made of copper, aluminum or high-efficiency insulation panels, the air carries the heat away anyway. Think of it this way: if you get into a hot car in the summertime, which is going to matter more: what the body's made of (steel versus aluminum)... or how many windows you can open? 🙂 Hmmm...

If you want those Cheetahs to last a long time, you had BETTER do something fast. Forced-air cooling is mandatory for them, according to Seagate. My suggestions:
  • Make sure the case fans all agree on which way the air should go. In at the front, out at the back.
  • Eliminate metal grates over the fans which cut down the actual airflow. Chop 'em out with a Dremel, a side cutter, or a jigsaw.
  • Measure the temperature of the drives. They should not be exceeding a surface temperature of 90F or about 35C in my opinion. If they are, bail the Jupiter case and get yourself an Antec SX835II or SX840II, which provides direct fan cooling for up to three hard drives and has room for 5 80mm fans, plus effective vent slots that let the air in easily. Or if you want something wowzy-looking, get a PlusView 1000: ooo, lookie here! 😀
  • Get the poor computer out of the hutch so it doesn't recirculate hot air through itself

You've pretty much identified your main problem, now it's up to you whether you're going to fix it.

Your CPU temp inside hutch: 84 C

Your CPU temp outside hutch: 68 C

You tell us what is causing the 16 C difference. I'm not sure if your mobo supports CPU diode temp, but if it doesn't, 68 C is still pretty high. I would say then it is either the way you installed the hsf or the way you configured the hsf is wrong. Why not your case fans? Because even with no case fans, your cpu temps shouldn't rise up to 52 C in 15 secs.
 
Let the computer cool off, take the side panel off, make sure it's not tucked away in a corner, leave room for air flow, then turn it on and see what the CPU temp gets to. If if it gets above 50, I'm either gonna say your heatsink/fan isn't adequate, or it's not installed properly. But either way, you definately need more airflow through the case. With 3 hard drives in there, you're creating a ton of heat and without proper ventilation, there's no place for the heat to go, so you computer turns into an oven. With an XP2100, and 3 hard drives, I'd recommend 4 quality 80mm fans if your case allows for that many, 2 in front, and 2 in back. And if possible, position the fans, or hard drives so that the front intake fans blow across the hard drives. A quality 80mm case fan flows at least 35 cfm at 3000 RPM or less... or at least, that's the standard I use, others may have a differnt opinion.
 
When I installed the retail amd heatsink - and it was a bitch- I was careful to match the groove on the base of the heatsink with the ridge on the chip socket. I did not use thermal paste, just the pad that comes with the heatsink, and I did scratch it slightly-tiny hole, while struggling to anchor the heatsink clips in place. Could this be enough to reduce the efficacy of the heatsink? Should I just get one of those after market antec cooling heatsinks and some thermal paste. Another question is how does my GA 7VAXP measure the system temperature? My open case system temperature is reading 42C within two minutes of booting up, but when Istick my hand into the case it feels barely warmer than the ambient room temperature (which is around 22c). Could I be getting some bogus numbers here?
By the way, thanks for all of the great suggestions so far!!!🙂
 
yea it seems like something is wrong with thoes readings. if your case is open and room temp is 22C then there is no way your case temp is gonna be 42C. and just a thought if you are not haveing any stability issues with you comp just let it run. Take te side pannel off and take it out of teh hutch. if its stable for a long period of time then its just a bogus reading. if its not yull get a lock or BSOD real qhick.

I kind of disagree because he has about $700+ worth of hard drives riding on this. Better make sure with some measurements of HDD temperature using a Radio Shack digital thermometer or something.

Or you can use your hand. With HDs, you don't need precise measurements. If they feel hot, then find some way to cool them. If they are not, then by all means you are okay.
