Replaced Corsair H110i GTX stock fans with SP140 LED series. Fans not spinning.

Hi all,

This was my first time building a PC in a very very long time. So please bear with me, if I have missed something simple. As the title should say it all, I have installed a Corsair H110i GTX CPU cooler in my system, and I replaced the stock fans with the SP140 LED series (simply just for the sake of aesthetics). The system does POST; however, the fans installed on the radiator just glow a faint LED light, but don't spin. The Corsair's logo on the CPU cooler also does not come on. I have checked the cabling twice to the best of my knowledge, but cannot locate anything out of place. the waterblock's cable is plugged into the CPU_FAN header, the USB cable is connected, SATA as well (though is connected to one of the three receptacles as another one on the same cable is connected to the optical drive). And the fans themselves are connected to the two waterblock fan headers. When I turned the system on, the CPU went up to the 89 C within 30 seconds when in BIOS, so I panicked and shut it down immediately. I would really appreciate any help at this juncture.Thanks in advance.

It would seem you have misread something because the specs do not indicate there are two waterblock headers, only one.

1 x U.2 port
1 x Aura RGB Strip Headers
2 x USB 3.0 connector(s) support(s) additional 4 USB 3.0 port(s)
2 x USB 2.0 connector(s) support(s) additional 4 USB 2.0 port(s)
2 x SATA Express connector: , Compatible with 4 x SATA 6.0 Gb/s ports
1 x M.2 Socket 3 with M Key design, type 2242/2260/2280/22110 storage devices support (Supports both SATA & PCIE SSD)
4 x SATA 6Gb/s connector(s)
1 x CPU Fan connector(s) (4 -pin)
1 x CPU OPT Fan connector(s) (4 -pin)

1 x LN2 Mode jumper(s)
1 x ROG extension (ROG_EXT) header(s)
1 x System panel connector


I would connect your pump to the waterblock header, one radiator fan to the CPU fan header and the other radiator fan to the CPU_OPT fan header. Or, via PWM splitter cable, both fans to the CPU fan header. You can also connect the pump to the CPU fan header and then split from the CPU OPT to the two radiator fans. I do not think the waterblock header has the proper PWM signal for your radiator fans. I could be wrong on that, but I think that's correct.

I have however asked for another of our moderators who has extensive water cooling experience to chime in here with his opinion on the matter.

If the SATA power is connected, you should get power and the pump should run even if you don't have the PWM CPU_FAN header connected. Everything would run full speed (or should). Can you tell if the pump is running at all?

I have one of these at home that I performed load testing on. You might check to make sure the fan headers are secure. Also, you might check to see the watts required to spin those fans up from a dead stop - most fans have a rating they require in order to spin up on startup - maybe the unit provides less than that...you could check with the Corsair AP fans just to check if they are getting power.

As for your temps, going back to the pump running, it doesn't make a lot of noise or vibration due to its lower power. Feeling the tubing, one of them should feel like a slight pulsing. I'm going to go with the pump not running or a mis-seat of the block on the CPU if the temps rise like that - even without fans running on the radiator, it would still be a couple minutes before you'd see higher temps...the coolant would have to absorb enough heat before you'd see a temp spike.

Have you tried other SATA connectors? Have you tried the Corsair AP fans? Was the cooler working prior to this, or was it a new install?

Hi guys, thank you for your answers. I re-checked all the wiring. In the end it was a faulty SATA power cable. I replaced it, and now everything works. In BIOS idle CPU temp after one hour is 28 C. That is within the expected range no? I also downloaded Corsair Link, I will check the CPU temp when under normal workload. Thanks again for the replies.

Nice. I figured Rubix could get you fixed up. Glad it worked out.

SATA PSU connector or the SATA connector on the Corsair cooler?

Either way, odd, but not completely out of the question.
