GPU hotter on BR than 775 board

[Mellowyellow]

I have a 8800gt Nvidia and it runs a lot hotter even at idle then when on my 775 mobo. What would cause this? is the BR giving it more vts then it needs? what options do I have to lower the temps? can I do it through the bios?
Do you know of any software programs that I can set the GPU fan higher?

Not sure, but Rivatuner may allow you to adjust the voltage, depends on the card. I doubt the MB is giving it more volatge than before. You probably just have more heat in the case from the chip than you did before.

The voltage on a 8800 GT cannot be adjusted via Riva Tuner. You can reflash the 8800GT bios with higher voltages. However, the 8800GT doesn't have the Volterra voltage regulator. Only the GTX260's, 285's & maybe the dual core GTX's. What is the fan speed on the 8800gt at stock settings? You can use Riva Tuner to set the fan speed when Windows starts. I run my 8800GT at 50% fan speed when windows starts. My 8800GT idles around 48C-51C @~50% fan speed.

You can raise the fan speed with it.

No way the Bloodrage can supply more volts to a graphics card as far as i know.

As suggested, probably more heat in the case, or in the system change you installed a newer driver with lower fan speed? Change in airflow?

Might be the bloodrage is making more use of the card than the previous board? What system are we comparing it to?

had a Q9550 in a IX38 abit Quadgt.
I do not think it is heat in the case since I am now watercooled when I was not before.
it starts at 25% fan speed, and with rivatuner I could not figure out how to set the minimum fan speed to 40% since any more at idle is just loud. I can deal with it being louder while I am playing a game. I could set it to 40% but it would always stay at 40% would never go higher when the temps go higher.
Idle is 70c, in game it gets 90c or more

its possible the 775 board your using is supplying not enough volts on the pciE slot and that results in lower temps ^^
but i doubt thats actually possible, it would probably just draw more current as the pwm on the vga will make sure it gets vgpu right...
strange... how much of a diference is it? same os and same driver? exactly the same card or different version, brand, vga bios etc?

You answered your question yourself, you are now water cooling whereas before you wer'nt.

Water cooling will keep your CPU cooler than before with your air cooling, however you are now missing a great big fan off your cpu cooler and therefore changed the air flow in your case.

Your original cpu fan would of been higher up then your GFX card and as hot air rises off you GFX card it would of been drawn in straight away by your cpu fan, but like I said before, now you have the absence of that fan, the heat is just hovering around until some other fan in your case expells it, making everything hotter.

Ding, Ding, Ding!!! See, this is why we come here, I have been under water so long I forget about silly things like airflow. Great call on this one.
