[SOLVED] H150I Pro CPU Fan Cable

[JFaTaL12]

About to buy a computer off my buddy and he said on the CPU Cooler (H150I Pro) that the CPU Fan cable off the cooler was snapped. The RGB on the fans no longer works but the fans still spin and the RGB on the actually cooler still work. Question I have is what does that 3 pin CPU Fan cable do? does that just control the RGB or do I need a new cpu cooler.

I would get some photos so we know which exact cable he is talking about.

I think it might be the tach cable - The 3 pin cable is the Tach cable which sends telemetry data to the block.

i am not sure what it might be on this diagram - https://www.corsair.com/corsairmedia/sys_master/productcontent/H150i_PRO_QSG.pdf

confusion started because the ml fans don't appear to have a cable just for rgb

Each fan has a 60cm cable with a 4-pin plug and requires 12V PWM power to function correctly.

So knowing what cable looks like is something to work with.

The motherboard fan header on the H150i doesn't really do anything besides report a pump speed to the BIOS, something you get from the iCUE/Link software as well. The somewhat disguised secondary function is as a warning if the pump should fail. Something has to be on CPU fan to boot. You can disable it, but then you are also disabling the emergency warning and you won't get it on other headers. Typically CPU fan makes for a lousy case fan header, so it is usually best to put the AIO cooler lead there, then use other board headers for the case fans.

all cable does is report pump speed to bios. If its the tach cable anyway, not sure why it would disable rgb on all 3 fans?

Thanks for the reply, you are correct, it is the 3 pin connector and I also believe it just reports the speed. RGB doesn't have anything to do with it and I'm currently trying to fire out why my RGB on the 3 fans turned off.

i have a H100i RGB Platinum and the only connection between the pump and the radiator are the tubes for liquid. Fans are attached to block for power so that is how the signal for rgb would be sent to them, and since they spin, its not that cable.

Stop. The H150i Pro RGB doesn't have rgb fans, its only got rgb on the pump itself.

The CORSAIR Hydro Series H150i PRO is an all-in-one RGB liquid CPU cooler with a 360mm radiator built for low-noise cooling and bold styling with an RGB LED pump head.

compared to https://www.corsair.com/ww/en/Categories/Products/Liquid-Cooling/Dual-Radiator-Liquid-Coolers/Hydro-Series™-RGB-Platinum/p/CW-9060039-WW

if the fans were rgb they would show you on the website. Gallery is misleading as it shows rgb fans in case but not on radiator itself.

so short answer to original question: you don't need a new cooler, it appears to work okay from outside but hard to tell without running it and seeing temps etc.
cable doesn't control rgb on fans as there isn't any on the fans. Only on the block. Only 360mm units with rgb fans are the Platinum & elite capelix models.

unless your friend replaced the fans with rgb ones.
