My computer is overheating. It says that the CPU temp reads 80.5 degree C. I've also noticed that the video card gets really hot as well. Any ideas of what is causing it and how to fix it? (Don't make it political this time) http://ubbxforums.ubi.com/images/smiley/16x16_smiley-happy.gif

CLEAN the dust bunnies out of the heat sinks and off the fan blades. Get some more fans blowing air around in there. http://ubbxforums.ubi.com/images/smiley/blink.gif

At times I've left the door off the side of my case and had a small table fan blowing into it. When I added the Radeon 9800 it got a lot worse.

Now I have a large case with 4 fans in it and the cooling problem is solved.

When I upgrade to the AMD 64 and a new motherboard it'll be water-cooling for the cpu, vpu, and mb.

First things first - make sure your fan is Ok on CPU, check the case fan(s) too.
Fan speed should be around 2500 RPM, your BIOS may show you the speed.

As FI Willie said - time for a dust check and clean too http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

Actually compressed air can do more damage, as air has tendencity to heat and collect moisture in compressing process...

Hi,

80 deg cel is near meltdown, surprised your system did not shut down from the heat. I had a AMD xp 2000+ that would run at 49 deg cel, just upgraded MB and cpu to 64 bit 3000 with a zalman fan and heatsink. Now I am running idle 34 deg and under med to high load 40 deg cel. Will see what it does under high load tonight. It is still almost 10 deg cel cooler idle from old CPU.

1: Are you overclocking? If so reduce CPU/GPU etc speeds to default and test.

2: As stated above check heatsink hygiene http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

3: Check that fans are spinning at their rated rpm; you should feel the airflow with your hand near the fan. I've had heat problems due to failing fans on NEW components...

4: Are your cooling system dimensioned correctly for your hardware? If you use a 9800 Pro or faster for example, you should have heatsink and a fan mounted on it. (I use a heatpipe sink with no fan on my 9800, works and is silent.)

5: When you mount a heatsink to a component that needs to be cooled its really important to have a medium that conducts heat from the component to the heatsink. If that is neglected you WILL have problems. (I believe one good brand of heat conductive grease is called "Arctic Silver".)

6: Do you have sufficient airflow through your cabinet? You could use a digital thermometer to check that the temperature inside your computer case dont exceed 30-35 C. The lower the better.

If I'm wrong correct me please... http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif

Mine is overheating too because of the summer weather, my room is at 28 degress Centigrade and my Graphics card can't take it. I have now opened both sides of my tower and I have a huge room fan the size of the tower case blowing in http://ubbxforums.ubi.com/images/smiley/16x16_smiley-very-happy.gif I'm not joking, my PC loves it it's the coolest it's ever been.

Ah, summertime! A-W, ya need airflow. If at all possible, mi amigo, you need at least one fan blowing cool air in and one fan blowing the hot air out. I'm in San Diego, a fair distance from the ocean, and no air conditioning, so I have a fan in the usual place to pull cooler air in (with a dust filter), a fan right next to my 9800Pro slot, blowing out, and another fan between my CD/RW and DVD drives, also blowing out. My system temp hovers around 49 degrees C most of the time, so it seems to be working.

Even in a room with little ventilation, as long as the air blowing in is 15-20 degrees C cooler than the air inside your case and it has someplace to go out at or near the same rate, there will be a cooling effect.

cheers

Put your computer in the freezer, and have the
cables for screen, stick, keyboard, mouse, etc
sticking out through the freezer door and set
yourself up to play next to it.
If it's really hot you join the comp in the cold.
OR
Turn off all fans and water cooling, let it get
real hot and fry green tomatoes on the CPU http://ubbxforums.ubi.com/images/smiley/784.gif http://ubbxforums.ubi.com/images/smiley/35.gif

Ya lol - this summer is really killing us all. Last night I watched a dvd & my CPU went from 39 idle to 57 during that 1‚Ĺ hour! That was of course with the case closed due to the noise of the fans - I opened it when the film ended & got this warm breeze & sweet smell of melting electronics in my nose.

S!

Personally, I don't consider a CPU getting to 50C to be a problem, after all that's only around 122F, which is only warm to the touch. Anything over 60 though is cause for alarm. The 80C that the original poster mentioned is really hot. My AMD XP-2100 has always run around 50C and I never have any trouble.

Hey Elektro, this will crack you up! A friend of mine built a computer INSIDE a dorm room sized minifridge &lt;ggg.&gt; He drill holes in the left side to run the cables for mouse, keyboard and video. The Mobo was actually mounted to the inside of the fridge with two optic drives near the top. The neat thing too was that there was still room in the fridge for a couple of six-packs. To load a new disc you just open the door of the computer, load the disc and then grab a cold one while you are at it! Too cool, quite literally. All the best, LongHorn

Well AMD recommend not running my Athlon XP 3000+ above 85C so it's still some way to go but my GFX go all funny in the heat I see little colourful patches on the ground and it begins to snow white static all around.

I've got three fans working inside the case. All of them blowing air to the inside of the computer. I've got one on top of the heat sink of the cpu, another one on the back and another on the side. Plus the little fans on the video card and the mother board. Any changes I should make?

I would recommend at least 1 intake fan on the bottom front, and two out-take fans in the back blowing air out. Generally the powersupply has a blower fan and then you just need to mount one more out. http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

You need to get a fan to blow some of that hot air out, preferably as near the top of the case as possible. The idea is to blow cooler air in, and hotter air out. Right now, all you're doing is circulating the hot air inside your case; convection ovens work on the same principle. http://ubbxforums.ubi.com/images/smiley/784.gif

i managed to knock five degrees c off my cpu temp by adding a fan at the bottom front to draw air in and by reversing the fan below the psu to expel air instead of drawing it in. the casing never gets warm and i've had no crashes since.only thing is,in my mind, there is now a conflict as the cpu fan is fighting the exhaust fan for air as they are only a few inches apart. would anyone know if reversing the cpu fan so that it draws air up through the heatsink is desirable ?

Depends an the heatsink. If it has a Duct around it that forces the air through the heatsink, reversing the fan will giva you better temperature.

Like to know what your rig is. The prescott cpus run very hot and really heat up the main board.

I would also check the heatsink contact on the cpu - is it a custom or stock heat-sink? Is this a new rig or have you had it for awhile?
80C is not a temp you want to be running at for any length of time.
