| " rel="nofollow - I have a AB350 Pro4 and as far as I can tell there is no AIO pump header. So when attempting to plug in my masterliquid 120, it's 2 fans, and my 5 other Artic F12 PWM pst (built in daisy chaining) case fans, what is my best options as far as what headers to use for each item? Thanks in advance for any help |

I got a Y-splitter (it came bundled with my Noctuas) cable for my 2 x 140mm, which are blowing through a h115i. The pump itself I hooked to the CPU fan header (it really doesn't draw that much current). Radiator fans I hooked to some other fan connector via the Y-splitter. This way you can manage both fans from 1 header. Only drawback is the lack of RPM reporting on the second fan. Bottom line, more fans - more Y-cables. ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

You are thinking about what is called by ASRock a W_PUMP (Water Pump) header. Water pump headers are meant for use with higher power usage pumps (12W+) used in custom water cooling loops. Mid and High end mother boards will usually be the only ones that have headers like that. You can see the fan header specs for all the ASRock AM4 boards in one of the topics on this page: http://www.asrock.com/microsite/AM4TSD/" rel="nofollow - http://www.asrock.com/microsite/AM4TSD/ AIO cooler pumps are much smaller than those pumps, and use much less power, usually ~3W. AIO pumps are meant to operate at their full speed or close to it all the time, since they cannot provide as much pressure as custom loop pumps. Given the typically poor manual provided by CoolerMaster (I have a Nepton 140XL), I'm guessing that the pump's connector is a four pin PWM type, is that correct? If that is correct, you can connect the pump to any of the fan headers on your board, they all work with PWM fans or pumps. You should configure that header in the UEFI to Full On or configure a Custom curve whose minimum speed is not less than 80% at lower CPU temperatures, or 100% constantly. Reducing the pump's speed will help if it is noisy, but you'll loose some cooling capacity. Or you can get a molex to three pin fan adapter, connect it directly to the PSU, and connect the pump to the adapter. It will run at 100% in that configuration, with 12V provided to the pump constantly. The cooler's fans can be connected to the CPU_FAN1 header with the splitter cable CM provides, if you use both fans. If you use one fan on the radiator, you could connect the pump to the other connector on the splitter, and free up another fan header. You will only be able to monitor the speed of either the fan or pump with that configuration. It's great you have the F12 PWM fans with their daisy chain feature. I would not use more than three fans total on one fan header. Check the Amp rating of the fans, if it is 0.250A or less, three fans on one header is fine. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

| Thanks for the replies guys, parsec yours was especially informative. My initial plan before I came here to double check was to run the pump on my sys fan 1 header at full speed, run the rad fans on the CPU header and split the 5 f12s on the remaining 2 fan headers. Sounds like once I double check the ratings and make sure it's all good then that plan will work just fine. Thanks so much for the help! |
