Windows 7: Overheating graphics card

so i have a Ati hd4850 graphics card and intel core duo e8400
anyway everytime i play a intense game like operation flashpoint dragon rising or call of duty waw or crysis its temprature rises to almost 110 degrees, on idle its 90 degrees.
i have fans runnning on maximum cleaned it from dust, and allowed it beathing space for air vents,, nothing worked.
any help?

New graphics card, water cooling, lower ambient temp

whats ambient temp.. and i have the same fans i had when i installed it.. why should it be overheating now..?

it seems that there may be a dodgy thermal connection between the gpu and the heatsink/fan.

you may have to take off the fan, apply some thermal paste, then rescrew the fan back on.

what is your case ventilation and cooling like?

Sorry

Ambient= room temp. you might also have the fans running against each other. they shouldn't all be pointing in or out. some pushing air in the others pulling out from the other side

i'm sorry guys your talking to me in a bit to much computer langauge and im not very tech savvy
whats a heatskink whats thermal paste whats thermel connection?

ok - the main chip on your graphics card (the gpu) runs at high speeds and get very hot, especially when playing games.

so in the factory they stick a large lump of metal (a heatsink) on top of it to absorb the heat, and then stick a fan on top of the heatsink to blow away the heat.

the heatsink is generally screwed tightly to the gpu, with a thin layer of thermal paste smeared between the two metal surfaces. the paste helps the heat to move from the gpu to heatsink smoothly and efficiently.

this may, or may not, be related to your problem.

normally i would say 'clean the fans with an old toothbrush, and increase fan speeds.' - you say you've already done that, so this is my next idea...

your computere CPU (and other devices) put out a lot of heat that needs to be removed. A layer of thermal paste is put on top of the cpu to haelp get rid of the heat and the heatsink (with all of its fins) helps still further.

I sample space between the cpu and heat sonk can make the cpu run much hotter. these things should be checked by someone with the skill to know if it is correct

i cant seem to see any lump of metal on my graphics card
how does it look?

Heatsink, usually has fins and a fan for cooling and it is there to help dissipate heat from what ever it is attached too. Your CPU has one as does your GPU.

Thermal paste or Thermal Interface Material "TIM" is a compound that is used to help transfer the heat from the CPU or GPU or what ever you are trying to cool to the heatsink.

It's like a sticky grease made of various compounds. It's there to help conduct heat away from the part you are trying to cool.

Sometimes this TIM isn't there in the proper amounts to transfer heat properly. Sometimes it helps to remove the old TIM and reapply some new TIM. Other times it doesn't help at all. You would need to take apart your GPU to do that.

Often times just adding case fans will help with a problem like yours. My GPU used to overheat during certain parts of Crysis with the multi player battle map until I added a few more 120mm fans to my case along with a controller so I can turn them up or down. I thought a few 120'smm and a couple of 90mm fan's would be enough also...I was incorrect about that...live and learn.

I now have 9 case fans which is what it takes to keep a single GTX280 cool during intense gaming in the summer time when it gets very hot in this room...80-90F.

There are also programs for ATI cards that allow you to turn up the GPU fan manually which can also help with cooling.
