Almighty1 Posted February 21, 2006 Report Share Posted February 21, 2006 General info I8kfanGUI is a graphical Windows application to show the internal temperatures and to control the fan operation on the Dell Inspiron 8000/8100/8200 notebook series and many other Dell notebooks. It's running under all current Windows versions (98/ME/NT4/2000/XP/Server2003). For the original DOS command line utility look here. The fan control and temperature detection is based on the fan and thermistor tests of the Dell diagnostics software. I got the technical details by disassembling portions of the Dell diagnostics software, because Dell was not willing to publish information on how to get control over the fans to prevent overheating. So this program uses undocumented Dell SMBIOS functions to detect the temperature sensors and to control the fans. This program is licensed under the terms and conditions of the GNU general public license. The source code is included in the distribution file.

Burrito Posted March 16, 2006 Report Share Posted March 16, 2006 Anyone know of any fan control/temp readings for the Core Duo laptops? I9kfangui version 2.4 is supposedly going to help that but wont be out for a while =/ Quote Link to comment Share on other sites More sharing options...
Guest Guest Posted April 1, 2006 Report Share Posted April 1, 2006 Anyone know of any fan control/temp readings for the Core Duo laptops?I9kfangui version 2.4 is supposedly going to help that but wont be out for a while =/ i have same laptop as u, latest i9kfangui works ok. sometimes when i open the program, the gpu reading is 20c (which is way too low --> wrong!), so i have to update, refresh, close the program, and reopen the program... sometimes, i have to do that for almost a dozen time, then after that it reads the correct gpu temperature. Under the same settings, sometimes bios takes over direct fan setting, so when i turn the fan high, it only stays for 2 seconds, then bios turns it down to slow or off. My settings are supposed to be correct since i follow the necessary procedure as listed in the forum/web which is maintain speed fan, autoupdate, uncheck maintan fan usage balancing, etc. BUT, sometimes the bios just lets direct fan control do the control. I have no clue what's happenning. But yeah, i'm waiting for the newest i9kfangui too! anyway, what's your average idle cpu and gpu temp? mine now is 4%load, cpu 26c, gpu 58, both fans on slow.

Have the same problems. Any idea if there is a modded bios for the go7800 that lowers the tresholds for the fan kick-in/out settings? Or maybe this is a driver option (extended coolbits?) Would really save us from overheating issues, and would be nice to NOT having to run external programs to control basic issues. Quote Link to comment Share on other sites More sharing options...
mew905 Posted June 28, 2006 Report Share Posted June 28, 2006 the fanguis should be able to control every fan in the Inspiron (provided the laptop is supported) but as far as I know, there are no bioses that lower the thresholds. if there were, I'd do it to my I5150 for more efficient cooling.

®®® Posted June 28, 2006 Report Share Posted June 28, 2006 (edited) There's a page somewhere for 9x00 DELLs. The program is called i9kfanGui i think. Try this new one. Yes, go here: http://mckenziedev.com Edited June 28, 2006 by ®®® Quote Link to comment Share on other sites More sharing options...
Bill Posted June 29, 2006 Report Share Posted June 29, 2006 There is also a new beta (and soon release version) of the new fangui over at the main site. Seems to support all the new systems just fine (multicore, ect), plus has many new features to boot. (multi processor dependent fan speed settings, much much better taskbar icon options) version3 beta is also a lot newer than 2.3 on some other site. I would recomend the beta, runs fine over here. Edit: Here is a really good look at the new version. Quote Link to comment Share on other sites More sharing options...
Almighty1 Posted August 26, 2006 Author Report Share Posted August 26, 2006 I8kfanGUI version 3.0 beta 5 is out (4. July 2006). This is the fifth beta version of the upcoming version 3.0. The changes I made to beta 4 are listed here. I'm publishing several beta versions before the final version because I've made fundamental changes and fixes to the previous version. The following fundamental changes were made to version 2.2.0: revised temperature control to support multiple sensors and fans in any combination system specific sensor and fan detection changeable colors for each tray icon updated minimizing to tray feature to make it more intuitive updated realtime cpu speed calculation for hyperthreading and multi core systems automatic detection and support of hyperthreading, multi core, and multi processor systems User interface redesigned and updated to Windows XP styles redesigned the history diagram for better readability support for Windows XP themes dropped support for Windows 98/ME Quote Link to comment Share on other sites More sharing options...

dabomy Posted October 29, 2008 Report Share Posted October 29, 2008 Hey, I think that i8kfan gui is confusing c with f, because it says that my current temp is 89 c, which is not true. Also, my temp peaked at 98c, is that too hot? I have an 8600m gt overclocked at 595/495 on a dell 1520 with 2g mem, intel core due 2.2ghz, vista, overclocking with ntune Quote Link to comment Share on other sites More sharing options...

Guest The Exile Posted November 21, 2008 Report Share Posted November 21, 2008 Are you the guy who made the utility? Anyway, this tool is really awesone, i had no way to control the fan speed on my laptop (Dell Vostro 1500), and with this i can force the fans to work 100% So i just wanted to thank a lot to the person who made this possible Thanks!! =D Quote Link to comment Share on other sites More sharing options...
Guest KLBUILDER Posted December 18, 2009 Report Share Posted December 18, 2009 I have a Dell Precision M6400, bought in June 09, and I cannot gain control over that fans to save my life. BIOS A09, 32 bit, XP pro. I've tried speedfan and I8kfanGUI, and neither one works at all. I8 will turn fans on, but something else always overrides them, so the system winds up fighting itself and the fans cycle on and off even more often than they do while under system control. Even when idle, my fans come on every 40sec and run for 20 sec NO MATTER WHAT! It's extremely annoying and seemingly unnecessary. Has anybody found anything that works for a Precision M6400?

Guest john poslof Posted December 8, 2011 Report Share Posted December 8, 2011 On the dell 9400 notebook has a fan problem. I came up with this idea of hooking fans to the USB ports and using the power from it. I knew @ boot up the USB ports are powered up everytime and put out five volts DC. The dell 9400 has two USB ports that are removable by the CPU using the red wire and the black wire or ground this will be the power out put to your fans. Just make sure that both fans are wired in parallel and not series. I have done this to other computers and worked very well. If you can power a USB hard drive or CDROM using USB why not your fans. The down side of using power from USB ports is when you plug other devices in the same port you got you fans wired too may not have the proper power to run other devices on just that USB port. Some times some laptops share the same USB power instead of having individual power supplies to each USB port. In most cases if you have a lot of USB ports located on your PC than your chances are greater. Good luck (= Quote Link to comment Share on other sites More sharing options...
