I'm having temperature issues, and I need help getting to the root of the problem. I built this computer back in March of 2006. I just recently purchased a nice new widescreen LCD monitor (1680 x 1050 display) and starting playing games on my computer again.

When doing some routine maintenance and cleanup, I noticed that my idle and load temp numbers seemed high.
I also had my computer shut itself off on two occasions. Once when playing an older RPG for only an hour. The second time was when I tried running the 3DMark06 test, which really bogged down the cpu and forced the computer to shut itself off.

Here are my temp numbers per Everest (idle/medium load):
Motherboard: 25C 25C
CPU: 44C 66C
GPU: 60C 67C
GPU Ambient: 44C 50C
Maxtor HD: 42C 43C

I don't overclock at all. Don't know whether I need another fan or is something else amiss.

I appreciate any and all help I can get in resolving this and making sure my computer is running at it's optimum level.


Case: Antec Sonata II
PSU: 450W Antec SmartPower 2.0 (ATX12V)
CPU: Intel P4 630 3MHz

RAM: 2GB OCZ PC-3200 DDR400 Dual Channel Platinum
Video Card: 256 MB eVga GeForce 6800GS AGP8X
HD: 200GB Maxtor ATA
Lite-On DVD-RW
Lite-on DVD
Monitor: 22 Samsung Syncmaster 226BW

well, when was the last time you thorough cleaned out all the dust in the fans and heatsinks?

you can also go to http://www.cpuid.com/pcwizard.php download and install it, it has a good benchmark utility and also gives more accurate temp and voltage readings. of you could post those both, we can get started.

thank you posting accurate info about your hardware.

Are all of your fans running?
Have you opened your case, and cleaned out the inside, lately?
If not, here's a tutorial that should help.

I have noticed a big difference in CPU temperature when using the Silver CPU paste as opposed to the standard Hi-Temp CPU Paste available at Radio Shack. The silver stuff is MUCH better.

When using the standard CPU paste, I have seen it keep the fan on all the time. When using the Silverized stuff, the fan will cycle. The heat transfer is far superior.

And yes, clean out all dust and blow out any heatsinks. If you don't have a rear case fan, they can help.

It had been a while since I cleaned the dust out. I did that first, but only for a minimal improvement in the temperatures. The temps I first posted were post-cleanup.

I also have and use the PC Wizard temp readings, but they gave me almost exactly the same measurements. Here are the results from the Global Performance Benchmark (Im assuming you meant this one) ran just now:

PC Wizard Rating: 2699.29
Processor Global Performance: 3588.925
Cache Global Performance: 19488
Memory Global Performance: 2411
Video Global Performance: 1440
Hard Disk Global Performance: 65


As for a reference, It is now 8:15am est. The room temp is 24C (75F). My computer has been on for 30 minutes and idling. My current CPU is 39C (102F) and GPU is 56C (133F). The temps in the initials post were from yesterday afternoon after the computer had been on for several hours.


Following advice from several posters on several boards, I removed the side panel of my case last night and remeasured the temps with the side open and also with a floor fan blowing into the case. Here are the idle temps:

Room Temp was 26C (79F)

(Case closed/Case Open/Open with Fan)
CPU: 42C 41C 41C
GPU: 62C 59C 56C
GPU Ambient: 44C 42C 39C
Maxtor HD: 43C 44C 34C



I also attempted to run the 3DMARK06 test again last night (the one that made my computer turn off last time). My computer actually completed it this time, but crawled through it ever so slowly. Here are the basic numbers from it:

3DMARK06: 2284
SM 2.0: 965
SM 3.0: 882
CPU Score: 861

Graphics Test 1: 7.998 FPS
Graphics Test 2: 8.091 FPS

CPU Test 1: 0.272 FPS
CPU Test 2: 0.436 FPS

HDR Test 1: 7.377 FPS
HDR Test 2: 10.262 FPS



Thanks all for the help! I really appreciate it. Hopefully we'll get it running up to speed in no time.

Cleaning the Interior of your PC



The only fan that isn't running, and I'm not sure whether it ever has is the PSU's rear exhaust fan.

The 450W Antec SmartPower 2.0 PSU came with the Antec Sonata II tower. The manual says this about this PSU's fan system:

THE PUSH-PULL FAN QUIET POWER SUPPLY
SmartPower 2.0 features an innovative design to help decrease noise during normal use, but which still allows for superior cooling capabilities as load increases. To this end, SmartPower 2.0 features both an internal intake fan as well as a unique external exhaust fan. The internal intake fan operates when the power supply is turned on. It rotates slowly to blow out the hot air from the power supply, and is thermally controlled, speeding up as heat increases. The external exhaust fan remains off to make sure your computer maintains a quiet computing environment until the power supply senses the required temperature to turn on the external exhaust fan.



The case came with a 120mm Rear Exhaust TriCool fan, which has a three speed switch. It had been set to Low (1200 RPM). I switched it last night to High (2000 RPM).

The case also utilizes something called the Advanced Chassis Air Guide (ACAG) system. It runs from the rear of the case to the CPU to provide fresh,cool air to the CPU without the help of any fans (passive cooling). It does come with two optional fan mounts though - one 92mm mount for the CPU and one 80mm mount for the VGA card (active cooling).

Here's the pdf link for my case's user manual. http://www.antec.com/pdf/manuals/SonataII_En.pdf


I'm not sure whether I should utilize these extra two fan mounts or not? Or whether the CPU needs an application of a better thermal paste? Either way, I'd need to be walked through the process, if they were deemed necessary.



My benchmark numbers definitely seem anemic and seem to indicate that my system isn't running at it's best level? Is there a better or more appropriate test or benchmark to help determine the current state of my system?

it may be a cabling issue and the airflow inside is not moving properly and is being blocked by cables. I have a feeling that's the issue. also, when you ran the benchmark test, what components were more closer to the center of the graph?

I don't think the cables are in the way, but some people think that the Advanced Chassis Air Guide (ACAG) system in the case is more of an impedance than a help. I don't know.

As for the benchmark results, that was only the second time I've ever run them and I can't remember how I measured up on the graph. I saved off the results to a .3dr file, but now when I try to open it, it can't find a program to open it with. Do you know what program I need to examine this file?

you can take a screenshot instead, you know.

as for the file it saved, here's the info.

View the file in MS Excel or submit them and view them in the ORB. The 3DR file is a zip file containing the 3DMark results in XML documents.

44 degrees C isn't that high, unless you are having other issues I wouldn't worry about it.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

so you think 112 degrees fahrenheit is not too hot?

Since the max temp on the Pentium 4 630 3.0 GHz, is 63.6C (146.48F), I'd say, it was well within specs.

44C is actually closer to 111F (111.2F). :thumbsup:

44C is what the cpu temp was at idle.

I had the computer shutoff, apparently due to exceeding the cpu temp. It gets into the mid to high 60's when under a medium load.

Ah...now we get the facts. Have you tried the suggestions previously made, clean out the case, clean the CPU heat sink and fan, reapply the thermal compound? Have you looked to see what you rail voltages are, if the power to the CPU it can cause a heat issue as well.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I had a feeling it was a temp issue. dc3 gives good advice, if you need help as to how to properly clean the compound off the heatsink and processor, let us know.
