what should a amd64 3400 939 pin cpu run temp wise?
mine seems to run around 50C and goes up from there when playing AH2, Tiger Woods (hi settings), & IL2 FB ...
it seems the only way I can now play these games is to have the case door open and a floor fan blowing into it... the 50C is with the door open and the fan blowing on it .. does that seem right?

not sure Eagler, I have a X2 3800 that is overclocked to 2.4ghz and at idle it is around 38-40C full load hits 50C.
You might want to invest in a 3rd party HeatSink Fan unit? I am using a Thermalright XP-120 and while big is darn near dead quiet.

ive got a AMD64 4000 (E revision) i think, the last revision. i use water cool
and usually 32 idle 35 AH load. id say yours is alittle hot but ok.
air cool id want 40 45 idle 45 50 AH load.

Last time I checked, 60C was the "worry point" where damage can start to occur. As long as you are peaking around 50C you should be ok. As long as the fans are working, not dirty, you have good airflow, I'd keep an eye on it but otherwise not worry too much.
Of course depending on the motherboard brand, you could have the hardware start cutting out clock cycles on the CPU to control temps at a much lower setting than that. I'd check the motherboard documentation and make sure you arent risking a lockup or CTD out of your games from the CPU trying to manage it's temp.

Try reseating your fan/heatsink.
Remove it, clean all mating surfaces, re-apply some arctic-silver, and refit the fan/heatsink.
You didn't say what fan you have.

I can't tell what my cpu temp is. I tried Intel's active monitor software (or whatever it is called), and it hard crashed my machine. Wouldn't even boot or show the BIOS screen thereafter, even after several power cyclings. I had to physically remove my cards and reinsert them to get the machine to be bootable again. I tried Speedfan, and it doesn't show any stats for my motherboard (an Intel motherboard for Pentium D).

That's way to hot IMO, my 3000+ ov at 2.4 is at 46° full with stock cooling (I've a good case it may help)
-
thanks for the info
the 3400 has an aero cooler on top of it. I used artic silver? - whatever the heat sink compound is everyone says to use.. The system is just over 12 months old and just notice this issue when I upped the vcard from 9800pro to 7800 gs co. I was having problems before on the 9800 trying to run IL BF. It started locking up after playing quick missions offline for a little while. I just figured the app was corrupt and didnt bother with it. I thought my lock-ups were the new video card but noticed they ceased when I had the case door open. Using speedfan it was showing a red flame next to the temp reading whenever it went over 50.

Could be the extra heat from the 7800GS.
Does your case have a blow hole, i.e. a place to fit a fan on the top of the case?
These really help getting rid of hot air that tends to collect and fill up from the top of the case downwards.
Any case I buy if it doesnt have one, out comes the 80mm hole saw.
Wouldnt recommend doing it with ANY components inside the case.
Poss 'dirty' fix.
Use one of the available HD Coolers, reverse the fans (so it blows outwards), and mount it in the top 5.25 inch bay.
Might also want to check you PSU fans are working, these help to evacuate the warm air at the top of the case.

Don't worry about it.
The limit of your CPU is 60 degrees C. You are 10 degrees C under that limit.
This is what is called in the industry as "as safe operating temperature."
You may be thinking that your CPU will be faster, somehow, as you get its temperature lower. Wrong. As long as the CPU is not generating errors, it is as fast at 59 degrees C as it is at 40 degrees C.
Lifespan? The CPU's lifespan is the same at 40 as it is at 59. The manufacturer guarentees it.
You should, of course, ensure all your fans are working, and that there aren't any dust bunnies living in the heatsinks.
So unless you plan on overclocking it, just make sure what you have is working properly and leave it be.

Yes and no. The CPU itself might run just as well at 59C as 40C, but if the motherboard uses Cool and Quiet or some other such temperature regulating software, it can cut out CPU clock cycles to try to control the temps, effectively slowing down the CPU - depending on the temp settings for when it is set to kick in. Splitting hairs I know, but to someone who doesnt know how it works they wont know the difference. The computer will just slow down.
-
Llama, if it wasn't locking up in the first place, I'd never of checked the temperature :)
I have never had a heat issue before but think this must be one now. Maybe the heatsink isn't seated as well or maybe the two sata drives(raid), 4 ide drives & two optical drives have finally choked any kind of circulation out of the box...
I cut a hole up top/side and have a 90mm fan blowing out. So with the other fan blowing out in the case and the ps fan - I have 3 out going + one of those slot fans that sit where the pci cards go - it blows out too.
In front/bottom I have two 80mm fans sucking air in + two of the ide's are removeable so they have fans sucking air in too ...
even with all of that, the temps climb into the low to mid 50's and will lock up when I try to play AH, tiger woods or IL FB with the door closed..
is SpeedFan accurate with their temp indicators? It shows a red flame whenever my cpu temp gets above 50c
-
While 50c is kinda high , it shouldnt be causing lockups. I noticed all the hard drives ,and optical drives you are running , along with a 7800 series VC , but no mention of the rating of your power supply . The problems you are having could be symptoms of an overloaded PS, you said earlier that going from the 9800 to the 7800 aggreviated it , so it sounds feasible . Just my 2 cents

You know, I didn't read about the lockups you were experiencing.
That said, 50 degrees SHOULD NOT be causing lockups.
I agree with 38ruk that this seems more like a power issue than a temperature issue.
I would be interested if you put the old video card back in and compared the temperatures again.

if it were a power supply issue, why then would the issue go away when the door to the case is open? Can that still be a flaky ps?
I have this 400watt ps
http://www.modthebox.com/review216_1.shtml
Is that enough to run my box?
Guess I'll find out as this 120mm fan
http://www.sidewindercomputers.com/de12trbllows1.html
and this heatsink
http://www.newegg.com/Product/Product.asp?Item=N82E16835109118
arrived today.

That PSU is borderline in my opinion . the 7800 series requires 20 amps on the 12 rail , yours is rated for 16A .
A PSU will overheat when it is being over worked and that will cause a system crash , so the fan blowing into the side of the case is more than likely helping the PSU to stay under the thermal limit . From the looks of it you soon find out which piece of hardware is causing the issue GL 38

the new heatsink lowered the temps some:
before

after

(might have got away with just cleaning the old one - it was dirty)
I haven't locked up in AH but IL2 FB did. Haven't tried Tiger Woods yet.
but I think you guys are right about the power supply..
thanks for the amperage info 38
I think that is my main problem and have a OCZ ModStream OCZ52012U coming. It has 26amp on 12volts.
Let you know how it goes
thanks again
-
Good to see ur temps are down alittle bit :) . I bet the new psu will fix the issue your having , id like to see how it turns out either way. I have an older antec 430W true power laying around here , its a 20A 12+ rail capabile . If you get into a bind PM me , and i'll trade you for your old one , i just need a know good one for a tester .

I also have a spare Antec 430W unit. I pulled it out of a rebuild and there's hardly even dust on it. I'd be glad to donate it if it will help. It was free :)
-
thanks for the offers, my ps from newegg should be here by the end of the week
I read that the computers now use the 12v rail for the cpu, that before it used the 5v. That makes the amperage critial on borderline setups as mine.
Wonder how many others strange/intermittent ah or other cpu issues are related to it. I noticed my 12v hasn't read above 11.2, closer to 11, since I have started measuring it. maybe another sign that it is struggling.
edit: Tiger Woods froze faster than IL2 FB
-
WOW i never noticed that in the screen shots above . 10.94v on the 12 rail is really a true sign of a psu givin up . Ive never seen one go that low before .

(http://www.pogbird.com/X45/new_ps+new_hs.jpg)
I installed the new OCZ modstream ps and all looks great now!
My temps are lower across the board and my voltages are higher and more stable.
I played IL2 FB for about an hour last night as well as Tiger Woods - both at max video settings and both played flawlessly.
This morning I bumped my AH settings back up to 1024 textures on a 1280 x 1024 resolution and flew around fighter town for about 45 minutes without a hiccup. (7 kills in two 109f sorties :))
thanks again for the power supply info, it pointed me in the right direction
