Qjimbo Posted October 20, 2008 Share Posted October 20, 2008 Hi, I have a 8800GT card, using Kalyway with the NVInject-512 driver, and I want to control the fan on my graphics card to run it slower (since I used to do this in windows all the time and it worked with no problems) I have tried using smcFanControl but unfortunately that doesn't detect any fans so I cannot use it. Are there any solutions to this? Thanks, Q Link to comment Share on other sites More sharing options...
spanakorizo Posted October 20, 2008 Share Posted October 20, 2008 i remember that i looked everywhere for this, cause i have also 8800GT but this a long time ago, when i thought kernel panics caused by the gpu getting hot when editing videos now my system is stable, i don't need to change the fan speed (kp where because of memory remap feauture) stock fan speed of the 8800gt is at 30% , why you want to change it? faster i would understand but slower?

Qjimbo Posted October 20, 2008 Author Share Posted October 20, 2008 Just to keep the noise down really, I use my computer for a lot of audio work (listening/recording/producing) so having a constant wooshing in the background is kind of a nuisance.

miki88 Posted July 7, 2009 Share Posted July 7, 2009 So, how you solved this problem? Is there any way to accelerate fan speed on 8800GT in OS X? My card is very hot and running on 30% fan rpm. In linux, I jack it up to 65% with nvclock, and in Windws wih Rivatuner, but I don't know how to solve this problem in OS X. I really want to avoid flashing at this point... this issue kepps me from using OS X on sunny days... Link to comment Share on other sites More sharing options...
Beukhof1 Posted September 1, 2009 Share Posted September 1, 2009 my problem is that my 9800GTX+ fan always runs on 100% is there a fix for it? Link to comment Share on other sites More sharing options...
Distemperus Posted September 6, 2009 Share Posted September 6, 2009 my problem is that my 9800GTX+ fan always runs on 100% is there a fix for it? I've got a 9800 GTX+ 512MB and it when the gray boot screen goes to black & then blue - that's when its fan drops to about 20% or so. I only have a proper device property for my card in com.apple.boot.plist that Chameleon uses. Nothing else graphics related. Guides: this is the one I used: http://forum.netkas.org/index.php?PHPSESSI...msg1929#msg1929 but there are other guides: http://aquamac.proboards.com/index.cgi?boa...&thread=569 http://www.insanelymac.com/forum/index.php?showtopic=91755 http://forum.netkas.org/index.php?topic=64.0 Note: google EFIStudio & that does essentially the same thing in a less command-line way.

pwolfe Posted September 16, 2009 Share Posted September 16, 2009 I am also having a related issue. I am using SL and a 9800gt.. I am only using an efi string in my com.apple.Boot.plist for graphics functionality. For me, the system boots with the gpu fan very quiet. But as soon as I load a game, or for example glextensionsviewer, the fans go to 100% and never lowers. Meaning, even after I have closed the application that was stressing the gpu, the fan never slows down. Any ideas a fix for this? edit: thought of something. My card is the new zotac eco 9800 gt. Could my problem be that the card is being overclocked by using a efi string for a real 9800 gt, and not to proper specs of this card? Link to comment Share on other sites More sharing options...
yochino Posted September 17, 2009 Share Posted September 17, 2009 i just recently got my GTS 250 up and running. i've been searching for a way to monitor and lower the temp of my new card to preserve it but it's just been impossible. noone seems to have a solution. I think flashing the BIOS (as some have done and had success with) is the only way. Anyone have any ideas? Link to comment Share on other sites More sharing options...
yochino Posted September 18, 2009 Share Posted September 18, 2009 I spoke with the people over at atMonitor and they told me that hacks have messed up SMC reader which is why atMonitor can't read the temps correctly on GPU's (and CPU's for that matter). Would it be too difficult for one of the gurus here to write some kind of SMC kext that would fix this issue? This would really make my hack complete...!!

yochino Posted September 22, 2009 Share Posted September 22, 2009 would installing netkas' FakeSMC do the trick in this situation? Link to comment Share on other sites More sharing options...
RetepNamenots Posted April 13, 2010 Share Posted April 13, 2010 Hi, I switched my PC from a build of iDeneb to W7 last April after my graphics card died and was replaced by an XFX 250 GTS. The card was driving me nuts under OSX, because it was not capable of controlling the fan speed. Unfortunately the card appears to have it's fans controlled by drivers, since even when booting Windows they will stay at 100% until drivers are loaded at startup. Unfortunately there was no fan control for my card in OSX whatsoever, meaning that the card fan would run at a very noisy 100% all the time. Have there been any improvements or fixes in this department? Or would it be a case of me purchasing a third-party cooler for my card and adjusting that?
