I have read through some 8800gt thread in lyn forum and found out that I must tweak the fan speed higher. So far I have tried rivatuner of various version (2.0 till 2.06), ntune and even did the regedit thingy, but nothing works&#33; <br /><br />Someone please kindly advice / list out the detail steps for me to raise the 8800gt fan speed. If can please do not link me to other guides from websites because i have mostly tried all of it. <br /><br />Extra info : 1. Rivatuner does not shows any option for me to raise the fan speed, it only shows the option to overclock my card. (even though it is <br /> suppose to show it just beside the overclocking page)<br /> 2. Ntune will not let me tick the option to adjust fan speed, the option is grey out.<br /> 3. Regedit -&gt; NVTweak -&gt;Coolbits value changed to 3. My nvidia control panel will hang when i click on &quot;change overclocking <br /> configurations&quot;. <br /> 4. I am using driver 169.21.
