H100i v2 settings/bios questions

[xsimplyjosh]

Hello all
I'm new to water cooling [not custom] 

and this is my first AIO i've bought. [Corsair H100i v2] which I'm using as a cooler for the 7700k paired with the 1080ti strix graphics [just some background info]

 

not intending to overclock for now as its brand new and working fine

First thing i noticed is it runs pretty damn loud [2700rpm] but to be expected with everything plugged in. [the pin is connected to the AIO-PUMP header on my Z270H motherboard

 

These are the questions to ask.
1) Has anyone has any idea how to set the fans speeds, i'm on corsair link and no matter how i adjust the fan speeds, according to the profile they still run fully maxed out

2) How about pump level, i can't seem to adjust it also for some reason, am I missing something out?

 

anyone experience can help me would be great or show me some example profiles to get started and i can experiment from thereon. also bios settings etc would be handy, im still learning and the aio is entirely a new thing to me altogether*

 

Am trying to get the aio to a certain level where it isn't too borderline annoying but usable. Don't mind a little bit of noise since i'm running 100% fan setup w/ the aio as exception

.

[im intending to replace the fans with either the noctua f12s or either the ML120 reds later on as the stock fan looks... very bad and cheap ]

are your fans connected ofnthe motherboard or pump?

I connected them to the ysplitter provided as usual. Is thatwhere my problem lied at?

Coming off the pump you mean? Or a Y-splitter that you plugged into a motherboard header  (this shouldn't be the case for the 100i v2, but its  important I check)

 

While you're at it, please post a photo of your corsair link

I will post it when i get home asap, outside at the moment so away from my PC

I pretty much followed exactly what was on the manual just for safety and good measures. Afaik there were these cables that I fiddled with

1) USB 2.0 Header to Micro USB for the Corsair Link data
2) Y-fan splitter, connected both fans to it, then connected the end of the splitter towards the AIO-PUMP header on the motherboard [z270H], maybe i might move this to cpu header tonight(?)

are you sure you have a h100i v2 and not a GTX? The v2 has fan headers coming off directly from the pump itself (i.e the fans do not plug into the motherboard)

Yea mine is H100i v2, as I don't think australian stockists even sell anything in the likes of the GT/GTX here anymore I will check again and update this reply/thread when i get home.

Read my signature... That is almost certainly your problem.

So just to confirm, the H100i v2 does not come with a Y-splitter, there are two fan headers (4-pin) coming off the pump block itself, and there is a 3-pin header for the pump that goes into the motherboard.

 

You definitely don't want to plug your AIO fans into the motherboard especially with a 7700K + ASUS board. The ASUS BIOS at the moment has a critical temperature of 75 degrees on the CPU temp, and will force any fan connected to a header controlled by the CPU temperature up to 100% if your CPU reaches that temp.

 

It is not unusual for the 7700K to hit those temperatures, so your fans are being ramped to 100% by the motherboard. With the H100i v2, there are fan connectors on the pump itself and the fan speed is controlled by the water temperature instead of the CPU temp (in watercooling, no sense to increase the fan speed if the water is not hot).

 

If by Y-splitter you mean the splitter coming off the pump, then you need to set the fan curve of the header to max power on DC mode (100% all the time) so that the H100i v2's pump would actually spin. Then you can setup your fan curve in corsair link, linking it to the temperature read by the H100iv2's water temperature.

Yes sorry I made a mistake. I did a thorough check last night, there are only three cables.

i guess building the pc last night took a toll as i was very tired so i wasn't remembering things properly even

1) One is the Y-fan splitter that comes out of the it only connects to the 2-fans nothing else*

2) [Detachable] USB2 to MicroUSB for CorsairLINK

3) fan header to connect into mobo

 

So set the CPU FAN in BIOS to 100% DC [not pwm]*?

I'm not overclocking for now and using stock for the time being so no 4.8/5GHz fancy stuff, just trying to learn the system [aio] before i start "tampering" with extras.

having a look now thanks for the advice. really appreciated

[xsimplyjosh]

@For Science! so it seems my issue is fixed thank you very much

pump must always be at high rpm [max output] right? because i hardly hear the noise of the pump even at this calibre, it's more of the "fans" that caused the noise for me.

 

I've uploaded my link profile at the moment in a pic. so far my case fan setup is
2xML140 fans at front [operating from bios at silent mode by default]

1x ML140 fan at rear [operating from bios at silent mode by default]

2x stock corsairs 120mm on the liquid pump [cpu fan output at 100%, plugged into the CPU-Fan header on mobo]

[xsimplyjosh]

i do get occasional core spikes in temps but not too concerned as it's not over a long period thank at least.

Glad I was able to help. Yes, the pump is designed to run at a fixed speed while receiving a constant 12 V in DC mode. You can select quiet or performance mode in Corsair Link though if you prefer to change the speed of the pump. Otherwise everything looks good on your setup!

[xsimplyjosh]

Now is finally working! thanks for helping me fix it. it was probably i set the pump to variable mode before which messed up the fans entirely to adjust on the software.

at least now flicking between quiet and balanced works thats what i need simplicity between two modes on CorsairLINK. rarely would i need to go on performance as i'm not overclocking just yet [well i will experiment later when i get customed to the new rig ins/outs]
