As referred to earlier, these cards are expected to run hot, but thats no reason to allow them to.

If the video card approaches 100 deg C + this heat is going to be transfered into the PC case, causing other components (CPU, RAM HDD) to run at higher temps. Putting extra fans on the case will help, but that doesn't make sense if you can cool the video another way.

If you set the video card fan at 60-65%, the temps are lowered dramatically - the only issue is that it may reduce the life of the cooling fan - whats cheaper to replace cooling fan or video card?

I will be using Rivatuner to set up a variable fan speed profile similar to the one I used with my X1900.

Although I am happy with the raw performance of my 8800GT - I am less happy with the high temps these things generate.

I guess we will have to wait and see how long these components last - they are usually obsolete before they fail anyway !

You are a bit wrong here. If the gpu hits 100+ C, it means that the heat stays on the gpu, so the case temperature won't get much higher. When the fan speed increases, then the heat is being transfered to the air inside the case, and so the temperature of the components will rise. The hotter the card runs, the cooler the case is. It's a paradox.

exactly.. you want a colder case you need a dual slot cooler that blows the hot air out, rather then into the case. Not necessarily a lower temp for your card

Yeah - good point, so are there any aftermarket coolers I can fit to my 8800GT that will allow the hot air to blow outside the PC case??

I am still keen to lower the card temps as well. I dont like the thought of delicate electronic thingies running at +100 deg C.

With a hot summer on the way in Aus, I dont want to fry my new toy!

Thanks

A good after market cooler will do both for you.

Make sure it doesn't void your warranty before you install it. I know it doesn't for evga, and I think it doesn't for BFG. As for which afermarket cooler to use... there are a few threads in here about this. Look in the forum for it.
