CPU temp?

[axemanxt40]

My CPU temp is 43 degrees C after running 15 hours of memtest86, that doesn't put any stress on the CPU...is that too high? My motherboard temperature is 34 degrees C

Here's a starting point. Go to the website of the manufacture that made your CPU and try under support and see if they have a listing for their CPU temperatures. If that does not work go to Google and type temperatures for " and put your CPU's name". You should get about a 40 page list. Hope you have awhile.

And if that doesn't work, turn your computer off at night. You could try a garden hose, but I think that could get your floor wet.

This is a PC that I built myself, and right now I got AS 5 and the Intel stock heatsink on it....

How about you tell us what kinds of components you're using here? CPU? Motherboard? The temps don't sound too abnormal to me.

< 70c on a P4 under load so at 43c your fine. Your moboo (whatever it is) may read high. Make sure you don't have a messy wiring job and make sure you have good airflow.

Surely

P4 2.6ghz C w/ stock heatsink
1024 Corsair XMS PC3500 RAM w/ heat spreaders
Asus P4P800 Deluxe motherboard
Sapphire Radeon 9600XT
Sound Blaster Audigy
Lite on DVD-Rom
Lite on DVD+-RW
2 x Hitachi 80 GB SATA Drives each with Vantec HDD coolers on them
Vantec 80mm exhaust fan pushes about 39 CFM of air at max
Coolermaster 80mm intake fan pushes 32.11CFM of air

all in an Antec Lanboy with the included Antec 350 watt PSU w/ blue LED

also got a UV LED light strip on the bottom of the case to make the window look pretty...doubt that is adding to the heat as its been off so I was able to sleep!

If you are worried and want piece of mind, go to the website and get you manufactures mamimum temperature list for that CPU. If you have an overheat protected motherboard it should shut your computer down before it goes critical. Use the search engine on the site and see if you can find info. that closely matches your problem.

I've built several Intel machines. I had the CPU fan quit and the rig ran fin for about 2 hours before it became unstable. Intel runs cooler than AMD, But it will still overheat. Make sure you have good air flow going through the case. To find a Temperature list, you can try overclockers.com, tomshardware.com and hardocp.com. I've been going to the sites for a long time.

Congrads on building you own machine. Makes you feel kinda special inside, dosen't it.

2.6c specs.

 

[axemanxt40]

So I assume if the intel site says the thermal spec is 75 degrees celsius, I should be safe? BTW when I had the case open I was getting temps at 36 degrees celsius. So would improving the neatness of the wiring in the case bring down the temp possibly?

 

[thunderhorse]

The wiring could help. Also try and get another case fan or 2 installed for better air flow. Make sure that all the dust is blown out of the case and off the motherboard, because dust is an insulater and will help retain the heat.

 

[axemanxt40]

The lanboy case only has spots for 2 case fans...an intake and an exhaust, in addition to the power supply fans. So I don't know what else to do.

 

[fredtam]

Your temps are fine. Tidy up the wiring. The only reason you would want cooler temps is to allow for higher overclocks. If you overclock and get above 60c underload I would suggest buying a better HSF.

 

[Ant001]

clean up your wiring, and if you are brave enough, get a dremel and start cutting

But, your temps are not bad. If your games start slowing down or you just don't like it to be hot, you should knock some holes in your case. Otherwise, don't worry about it.

 

[axemanxt40]

Would putting a better heatsink help reduce the temps?

 

[fredtam]

A new heatsink would put more heat into the case air which would lower the temps. However if you are not getting the hot air out of the case it won't do a lot of good. Given your limited options for more case fans and airflow patterns I wouldn't expect anymore than a 3-5c reduction in temps even with an expensive/efficient HSF. The ambient air temps have a lot to do with it. Do you have the heat on? Like I said before your temps are good and even if you were overclocking your cpu would probably hit a wall long before you got the temps up around 70c using stock voltage. So really unless the noise bothers you I would keep the stock fan which is highly efficient. Its silly imo to spend a bunch of money on a aftermarket HSF that will only give small temp drops and no performance gains. The next logical step after a stock intel fan is water cooling which I would only suggest for serious overclocking.

 

[axemanxt40]

Alright, thanks a lot fred I really appreciate your help!

Just to post an update, I believe I have corrected this problem...and the source was air flow issues apparently.

I removed the standard flat IDE cables for my optical drives, placed a 3 connector coolermaster rounded IDE cable in its place, also I took the excess power cord wiring, and stuffed it up on top of the case in a small little spot between the PSU and my 2 optical drives. I am now getting idle temps at 28-36 degrees celsius depending on my room temperature (which depends if I have the window open ). And my max load temps with Sandra burn in wizard and Prime95 go to 46-50 degrees celsius. So thank you everyone for the opinions.

I, personally, don't think you had a problem to begin with ...
