Patty37 Posted August 14, 2018 Share Posted August 14, 2018 Hi, I have just noticed on Link 4 it shows one of the fans on my H100iGTX at 0RPM. Both fans are spinning. I have an Asus X99 Deluxe motherboard. Does anyone know how I can fix this? I have post a picture of the problem below. Thanks folks! Link to comment Share on other sites More sharing options...
c-attack Posted August 14, 2018 Share Posted August 14, 2018 There is only one speed sensor for the pair of H100i GTX/v2 fans, so there will only be one speed in the software. Usually first step is to make sure the motherboard/BIOS control for the header powering the cooler is set to disabled/Full Speed or 100% in some other way. However, since you pump speed looks dead on for Balanced Mode, this is probably not the case. Double check, since this can affect the fan reading and behavior as well. Do you have any other monitoring software running like HWINFO, AIDA, or AI Suite? These have been known to trigger a false reading in the past. If you change the fan speed via fixed rpm or %, do the fans respond? Link to comment Share on other sites More sharing options...

DevBiker Posted August 15, 2018 Share Posted August 15, 2018 Not got anything else running. So it will only show one fan's speed despite both of them working regardless? Yes. Just to confirm ... you have the fans plugged in to the header on the cooler, yes? Link to comment Share on other sites More sharing options...

c-attack Posted August 15, 2018 Share Posted August 15, 2018 Yes, it is a standard 4+3 pin splitter so one speed sensor for both fans, just like if you plugged two fans on a splitter into one of your motherboard headers. Are you able to control the fans at all? Do they respond to setting a fixed % or RPM? Link to comment Share on other sites More sharing options...

c-attack Posted August 15, 2018 Share Posted August 15, 2018 Swap the two fan connectors for the radiator fans, so Fan 1 goes to the other connector. This will put the 4 pin sensor on the other fan. Link to comment Share on other sites More sharing options...
