I have been having heat problems since i built this computer

currently the specs are

pentium 4 @ 3.4Ghz
1024 mb RAM (ddr2 duel chenel)
256mb ati X600 video (pci-e)
100gb ata HDD master 120GB IDE slave
Intel 925xcv mobo
450w PSU
Zalman 7700-AlCu
ac5 paste

my temps are best theyve been at the moment. my computer will idle at 45 degrees and under load will go up to over 70 degrees in only a few mins. by then i stop whatever im running from fear of it getting too high. the idle sems ok but why does it get so much higher on load? from what ive read when idling at 45 the load is usually only in teh 50's why does my temps change so much?

also how do i tell what type of cpu im running? (northwood prescott etc)

also im using speedfan to check temps

cpu-id "google it" will tell you more info on your cpu mobo ram ect.. and i think your running a prescott core which tends to run hotter then normal cores soo. you should be ok, do you have it OCed?

geforce4 256mbs
Asus p4p800-se

no its not overclocked at all, i was just running a game and it went to 71 degrees and its not even full load

how do i get my cpu id?

If you have a P4 Prescott (aka "hot potato"), the temps you're seeing are not uncommon...you have nothing to worry about. Google something like "P4 3.4 temp" & you'll see

Hellz Yea!

Hellz Yea!

Intel specifiesa tremal treshold of 69*c for a P4 operating at that frequency.

You should be fine, but I would definatly shoot for a lower number.

will overclock fo food

ok well this program tells me its prescott so that does explain a little bit. now when i go full load for more then 5 mins the temps go above 75 degrees and i stop before it gets any higher,
i have teh side of the case completely off, any advice?

You cannot overheat a P4 to the point of failure...it has built-in thermal protection circuitry. It will 1st throttle back...if that doesn't lower the temp, it will shutdown, but it will NOT burnout.

Hellz Yea!

so what your saying is i shouldnt bother trying to lower temps cuz there fine where they are for now?

"You cannot overheat a P4 to the point of failure...it has built-in thermal protection circuitry. It will 1st throttle back...if that doesn't lower the temp, it will shutdown, but it will NOT burnout."

I didn't know that. What about amd?? any similar anti-overheating technology?

"so what your saying is i shouldnt bother trying to lower temps cuz there fine where they are for now?"

You should always strive for the lowest temps possible. But if you have a Prescott, your temps are not unreasonable. If you're system isn't unstable & there's no signs of throttling, I'd say you have nothing to worry about. If you don't know if your CPU is throttling or not...this free program called "ThrottleWatch" will tell you. It works for the P4 & A64:

"What about amd?? any similar anti-overheating technology?"

I don't see it mentioned very often, but YES, the Athlon64 has similar on-die thermal protection. I'm looking for a decent site to link to, but in the meantime, here are some clips that I found at various sites:

"...all Athlon 64 chips now ship with a heatspreader and sophisticated on-die thermal protection equivalent to that of the P4"

"ALL Athlon 64/Athlon 64 FX/Opteron processors have a built-in, hardware-enforced thermal protection mechanism that will shutdown the core if it exceeds its specified maximum temperature - this is completely independend from any motherboard-circuitry."

"every K8-class processor (Athlon 64/Opteron/Mobile A64/Mobile Sempron/Turion 64) has a built-in, hardware-enforced thermal protection mechanism that will shutdown the core once it exceeds its set maximum temperature"

Hellz Yea!

well do you have any suggestions to lower the temps? i only have one fan on teh back so i have the case completely open, would a new case with multiple fans and sides on be better then a open case?

any advice to lower temps would be appreciated

Removing the side panel defeats the purpose of having case fans.

Hellz Yea!

ok i was playing a game, cpu load was about 65% and temp was at 72 degrees, are you sure thats not too high for not even full load?

and if side being off is same as having extra fans ill just leave it off for now

Thanks for the info jam.

"and if side being off is same as having extra fans ill just leave it off for now"

Removing the side panel defeats the purpose...by doing so, the fans that you do have are now ineffective.

You still haven't told us what CPU you have...is it a Prescott or not?

"Note that the Prescott running in the mid 70’s under load is considered "normal" by Intel’s standards."

Hellz Yea!

yea i said it was a prescott in my third post i beleive it was

and taking off the panel makes the fans ineffective, so does that mean that if i get several fans and put the sides on its better then having the sides off?

also cpu has been diling aroudn 50 today this cuz its warmer inside (however this is winter so whats gonna happen in summer i dunno)

A couple things:

Make sure the entire material editor sample swatches use a standard material even if the material is not used in the scene.

Choose 'get material from scene' and turn off 'root only' to see all material types currently present in the scene. It sounds like the model may have a Vray material buried in a standard material slot somewhere.

Check the Environment map

Make sure all render engine types are not set to Vray

Will overclock for food

sorry, wrong thread. I had multiple tabs opened.

Did you buy the PC preassembled, or did you build it yourself? If that were my rig, the first thing I would check is if the heatsink is in absolute flush contact with the cpu.

I actually had that problem before, when I installed my heatpipe cooler. It turned out that the base of the heatsink had a gap in the middle which produced a concave (such as spoon) resulting in average idle temps, but would jump up significantly to 66*c + the second after opening a game. So I would advise you to, if your (knowledgeable enough) reinstall the heatsink with a freash drop of compound.

jajajja

Was a that a 3dstudioMax misplaced post?

Free

right you are ken, err... fennerman. yeah, messing around in 3ds max is a fun hobby, I got the special student discount price ;-P now what did I do with that edit button

bvdave, A good way to verify if the base of the heatsink has a smooth, flat surface. Line up a ruler or a credit card from tip to tip on the bottom of the HS, then hold it up to a light source, if you notice a hole(gap) where light is shinning through in the middle then you know the culprit of your problem. If you are in fact going to attempt to reinstall your HSF assembly, then make sure you follow this detailed instructions: its quite simple.

Common sense not required

Unfamiliar with whether you're running a 478 or a 478-M you might check the numbers on your chip and find out. -M is for mobile and is not accomodated by a desktop board and a desktop cpu isn't accomodated by a mobile board. However, all is not lost.
Go here:http://www.intel.com/design/intarch/designgd/251319.htm
Download the pdf and it tells you how to fix it so the board and chip match.

If you're a victim you can't do anything about it. If you're responsible you should.

Leave the sides on-- it creates an airflow-- air in front, circulates past hot components, shoots out the back.

Again, it's like a VW.

Hi.
I actually had a similar Problem with my AMD Athlon XP CPU. It turned out that the problem was that in the space right under neath the CPU Fan where the Fan contacts the Heatsink; that area was full of dust. You can check if there is dust under there. Another possible solution is that you could maybe get a new CPU Cooler. I also have an Intel Pentium 4 which has a Prescott core. and My CPU never Runs that hot under load. The Maximum it goes to under a load is 56 degrees celcius.
