i have a evga 6800 128mb video card. it has a large heatsink and fan (same one as on a 6800gt. but i was wondering if i could somehow make the fan speed up even when not that hot. the fan does go faster as the card gets warmer but i would like to ajust it manually. is there any software that allows you to control the speed? it idles around 55c-60c.

It is dependant on your hardware, if it is feasible to do so.

But give this a try,

SpeedFan

PS - 55-60 on idle is quite warm. What about under load?

max i saw was 70c under load. but that was when it was 25c in the room. usually 67-68. this is the GPU. the ambient is about 10c cooler. but speedfan says that its its: local temp- 38c and remote temp-31c. which one is correct? and no i could not figure out how to change the fan speed using speedfan.

I would say the remote temp would be more accurate, But I am not too sure.

Have you tried changing the Fan Speed in the BIOS. I don't know if it is possible to do so with your GPU Fan though.

Any software come with your card? nTune?

I think remote temp is the internal case temperature (the air inside the case). Local temp could be the chipset, or maybe a temp sensor near the MOFSET. I think (think) that even though they arent designed to be plugged into fan speed controllers, they might be compatible. The fan headers on your GPU heatsink might fit into the headers on a fan speed controller. Better yet, pick yourself up one of these. It will probably lower your temps by about 20%, and it's pretty much silent all of the time.

no, i just wanted to see if i could get my card cooler for free. i already spent alot on upgrading this machine. dell dimension 8200 pentium 4 2.4ghz 1.25gb pc800 rdram (friggen expensive) 200gb seagate HD evga 6800 128mb stock (im thinking of OCing and unlocking) soundblaster live i upgraded memory, HD, and video card. it runs bf2 on high. so im just trusting if it gets hotter during OCing and unlocking then the fan with speed up and ajust to the hotter conditions. i might stay stock though. it runs bf2 fine so im good. maybe when FH2 comes out i migh have to overclock it.

RIVATUNER I have 3 preset autolaunch fan speed profiles I set dependant on core temp. But you can also set it up to run 100% at all times, 2d/3d. You can monitor gpu stats, control fans and clock speeds with this tool. A definate must have. I had the exact same heating issues as you (60*+ idle temps w/ my stock hsf), check for my post below, as I just upgraded HSF. nice and cool 33-36* average idle temps now.

rivatuner is great. i ran the ran the fan at 100% while playng bf2 and it was cooler by about 4c. maybe now i will overclock. anyone know what clocks are capable on a evga 6800 128mb ?

My suggestion is to run the a stress test to find the barriers of your core clock and memory and watch your temps with RivaTuner. I ran ATITool (yes it'll run a nvida card) and ran the memory and video stress test. It's pretty long, so put time aside, but gave me great insight on what my card does at different settings and temps. Riva Tuner also has a stress test. Then run a benchmark like 3dmark and check it for artifacting. Tip: run RivaTuners "Hardware Monitor" so you can go back and see how your system took the stress. when I was running stock cooling I pushed my 6600gt from 525/1050 to 560/1200. Now with aftermarket HSF I am only running at most 50* on full load. Your mileage will definately vary, so don't use this or anyone elses settings as anything concrete. I have pre-set fan speed profiles. Check this out http://userweb.suscom.net/~msl/RivaTuner.htm It's a great little tidbit on some of the things you can do with RivaTuner. It's a great little tutorial on setting up fan profiles as well as clock speeds. GL!
