suarsg Posted December 7, 2018 Share Posted December 7, 2018 I had a Corsair H100i v2 previously. Its pump died yesterday so I replaced it with the new H100i Pro. Because the fans were quite noisy on my old AIO, I replaced them with "BeQuiet SilentWings 3" PWM fans (max. 2200rpm) and everything worked great, so I put on the same fans on the H100i Pro. However, something's wrong with the fan control. I have to put them to 90% in iCue to get them to actually spin. 99% gets me around 800rpm, 100% is 2200rpm. 99% with 800rpm is way too little cooling and 100% is too much noise for too little benefit and there's no in-between. What's going on? Link to comment Share on other sites More sharing options...
Corsair Employees Corsair Jam Posted December 7, 2018 Corsair Employees Share Posted December 7, 2018 Can you hook up the original fans and see if you get the same results? If you have the same issue with our fans, then it may be a bad fan controller or something within the software causing this to happen. Link to comment Share on other sites More sharing options...
c-attack Posted December 7, 2018 Share Posted December 7, 2018 I'm afraid the SW3 PWM series has problems with Corsair controllers, including the Pro coolers and Commander Pro. You can see the basis of the problem here in this review. There are various other threads across the usual sources as well. Link to comment Share on other sites More sharing options...

According to that article, having them voltage-controlled instead seems to work. Do you think buying an adapter-cable that goes from 4pin to 3pin that I can use to connect the fan as a 3pin voltage controlled fan to the AIO would work? I don't know if the H100i Pro supports voltage control and if all of that is even a good idea. I mean, the same fans used to work with the old H100i V2 somehow...

c-attack Posted December 8, 2018 Share Posted December 8, 2018 No, the Pro and most other AIO coolers do not support DC 3 pin voltage control. If you really want to use them, the best option would be from the motherboard and trying to manage that steep percentage slope. As the owner of 8-10 SW3 fans and even more SW2, I can see why you like them. However, it’s not the greatest radiator fan (SW2 terrible), particularly at lower speeds. Those ML fans that came with the cooler may give you better performance with acceptable low noise at moderate speed. Where the SW3 might be more compelling is if you do indeed run 1500 rpm+ on the radiator. Nothing is really quiet at those levels, but the SW3 may be a bit more diffuse and their blade geometry is more effective on the radiator at those higher speeds.
