Video card keeps overheating.

My radeon 6450 card heats up and causes my comp to restart constantly during bfbc2 and other games, and it's getting annoying. The only fix I can think of is to stick a desk fan inside my pc. So does anyone have any thoughts, suggestions?

EDIT: Okay, now i can talk about it more.

As i said, my video card is overheating constantly, even when the computer is just 'idling'. screen flickers, goes blank. then it starts back up again. No, I don't believe I've ever overclocked the GPU, but I can't be sure. So, to temporarily avoid this annoyance, I've stuck a little desktop fan facing in the case. yes, the case is wide open with a fan inside it. It looks bad, and it takes up space. So what's up with this? Please, please please give me ANY suggestions as to how to get this problem fixed. should i buy some fancy heatsink for my card?

Antec 900 case
visiontek Radeon HD 6450 (is this all the info you need on the video card?)
ask me for more info on my machine, if you need it.

THANKS

So it is idling right now at 46 degrees WITH the desk fan in it? If so that is way high considering you have a desk fan in there too.
 
I'd suggest that you get some temps when the fan is not on. If your good with hardware, you can do what i did. I also noticed that my card was getting load and very hot, so i cleaned the comp and made no difference. So i took apart the heat sink on my card and cleaned of the gpu thermal compound and applied a new layer. Believe it or not it worked. Now to how safe this is..... :)
 
wow. i'm starting to think this is an issue with all ati cards. my 6870 overheats and crashes my computer just playing counter strike source. yeah.
i also have an antec 900 with a side fan.

don't these cards have auto fan speed?
i have to manually set it every time i want to play and it's annoying.
 
Dowlonad MSI afterburner and see what your temps really are at. 6450's run very cool, I'd be very surprised if the card was overheating.

Also, the MSI afterburner you should be able to manually set the fan speed on the card (depending on the model of card, some you cannot), this would atleast stop you from needed the desk fan.

Also, what motherboard and CPU are you running? Are you sure it's not the CPU overheating? An Antec 900 has good airflow for the card. But have you overclocked the CPU? What heatsink is on the CPU?

No its not. Its a regular GPU temperature. Desk fans aren't going to make a difference on the reading because its not sucking heat from the actual chip/dye itself - that's the job of a heatsink.

Standard idle temperatures are anywhere from mid 30-s to 60's. Higher end cards will run closer to the 60's.

When you hit 80's your getting hot. 90 is too hot. Many chips/dyes are rated for 110 at which you have a meltdown. Most auto shutdown at 90ish.



As for the original poster: If you have another computer or a friend with a computer try installing your graphics card onto his computer and giving it a go. You're issue doesn't sound like a heat issue - it sounds like a system stability issue. Could be your power supply, or overclocking settings on your motherboard.

If it is a heat issue it will be reproducible constantly without games. IE) Turn on your computer, wait x-number of seconds and it turns off.

46oC is too hot for a 6450 at idle. And of course a desk fan will effect the temperature, lol

Afraid not. I've worked in the embedded industry and your typical arm CPU found in your common every day devices operate at about 35-45 degrees with a heat-sink and no fan.

Their recorded idle temperature was 39 degrees Celsius.


Heating issues are always easy to diagnose. If you overheat once idle (can always be reproduced with the same time intervals), you will subsequently trigger the overheat shutdown within a very very short about of time because temperatures dont dissipate that quickly. Its not random.

Besides your catalyst control center provides information:

To put it in prospective relative to the chart, this is a Radeon 5870 at an ambient room temperature of 23 degrees Celsius.
