milannnnn Posted April 20, 2016 Share Posted April 20, 2016 I meant on this piece of text: Quote 82h Burst Enable: 1. Host writes command byte 82h (Burst_Enable) to port 66h. 2. EC will issue SCI to host while OBF=1. 3. Host reads via port62h. If 90h obtained, it‘s Burst Ack. 83h Burst Disable: 1. Host writes command byte 83h (Burst_Disable) to port 66h. 2. EC will issue SCI to host while IBF=0 Quote Link to comment Share on other sites More sharing options...
IL_DECAMERON Posted April 20, 2016 Share Posted April 20, 2016 According to the scheme of the motherboard controls the fan EMC2103 ... Might be worth looking in this direction? The link you can download a schematic diagram of Lenovo Y580. See page 39. https://cloud.mail.ru/public/4kTW/5bVYBrQQQ Quote Link to comment Share on other sites More sharing options...
milannnnn Posted April 20, 2016 Share Posted April 20, 2016 I don't think we need to go that far Just need to figure out how to write to those registers ("Host writes command byte 82h (Burst_Enable) to port 66h") in order to enable that full speed / burst.

IL_DECAMERON Posted April 20, 2016 Share Posted April 20, 2016 I quote from the datasheet: "The EMC2103 communicates with a host controller, such as an SIO, through the SMBus. The SMBus. is a two-wire serial communication protocol between a computer host and its peripheral devices ". Interesting information on the fan control is on page 57 http://ww1.microchip.com/downloads/en/DeviceDoc/20005250.pdf Quote Link to comment Share on other sites More sharing options...
FastR6 Posted May 1, 2016 Share Posted May 1, 2016 It is better to buy a cooling pad with big fan. Quote Link to comment Share on other sites More sharing options...
grzybolevsky Posted May 15, 2016 Share Posted May 15, 2016 I don't think so, i have Zalman zm-nc11 and temperatures are still high. Quote Link to comment Share on other sites More sharing options...
Dimon1358 Posted April 11, 2017 Share Posted April 11, 2017 Anyone got solution for "overclocking" the fan? I can only set fan speed up to 85,7% (thanks to the IL_DECAMERON). Quote Link to comment Share on other sites More sharing options...
