Corsair H100i Pump Speed

[Sogo]

Hi guys, im new here so... SUP!

 

I have one doubt, I've noticed my H100i GTX pump seems to be running around 1500 RPM most of the time. It doesnt matter if i switch it to Quiet or Performance it always ends up there, BUT if i switch to quiet then to performance it very briefly shows up to 2160 RPM.

 

Is this normal? I tried to find a similar question but i couldnt and im worried it might not be working properly.

 

Thanks in advance for any answers.

Hi,

 

Performance mode RPM should be around 2760 (+/-30) RPM in Corsair Link.

Please check the setting in Your bios for the CPU fan header, Q-FAN or any fan control option should be "off", manual (100%) or full speed (max) - I don´t know how Asus calls these exactly.

 

Connection:

- 3PIN connector of the CPU block to CPU/CPU1 header on MB

- Y connector to CPU block

- 2 x 4PIN fans to the Y connector

- Data cable to CPU block , other end to USB header

 

If You use any Asus software under windows check if it is not "regulating" automated the CPU fan speed (if yes than it is not good, as the CPU cooler should have always the 12V power from the CPU header). Any fan control for the CPU header should be off or manually set to max speed (bios or other SW under windows).

 

Your fans of the H100i GTX are regulated directly by the into the coolers CPU block built in fan controller (You can configure these with nice fan curves in the Corsair Link software).

 

Try and check Your results again,

 

BR,

Thanks for your reply.

 

I have it connected exactly as you say and the AI Suite inside windows shows the CPU fan grey (uncontrollable).

Just to make sure about the power it's getting i changed the BIOS CPU Q-fan to manual and set it to 100%, the AI suite continues to show it grey and the cooler pump RPM now hovers around 2000 in performance and 1800 in quiet mode.

 

Now putting it on quiet, waiting 30 secs and then changing to performance does ramp it up to 2600 for half a sec before it starts crawling back down to 2000 again in around 1 minute.

 

BTW the information tab on the cooler pump says max RPM is 2580.

EDIT: Information tab now shows max RPM is 2610, so i think it might show the max its gotten to, not the actual max.

Ok, so Q FAN is setup properly. Are You using the CL software to set up the pump and check it´s rpm? Still sounds strange, the pump rpm should be constant (+/- 30) when set to some mode. The 2600 rpm not sounds bad, but it should hold it. Can You somehow connect the cooler to your PSU directly? (SATA or Molex to 4Pin splitter). I see 3 possible "problems":

 

1. Your CPU headers 12V is not holding up (fluctuation)

2. The ASUS software still somehow jumps into the picture and do some control in the background (I read here in the forum some problem with the AI software already)

3. Cooler broken, contact corsair support (possible RMA)

 

Example splitter to power Your cooler from the PSU directly, just check if You want SATA or Molex power connector version:

Recently installed H100i GTX and it keeps my i7 3770k nice and cool. no problems except with Corsair Link... actively reads all temp and fan sensors except the cooler pump and CPU (cooler) fan which are stuck at 2850 and 1200 respectively. The changes to performance settings fail to do anything.

 

I did manage to get it actively reading the pump and CPU (cooler) fan by checking all the connections. It worked great for a couple of hours but no longer.?! Back to non responsive and no wiggling of wires or finger crossing helps.

 

I have an ASUS MB (P8Z77 - V Deluxe) and I have disabled the CPU fan monitoring in the bios but that has not worked...

 

So, what is the solution? Run the CPU fan cable from the pump to the PSU ? Seems to me there is no communication between pump and software GUI?

 

The cooler is working fine. It is the software that is not for the pump and fans.

Hi,

 

The CPU fan monitoring is ok to be turned on in Your bios, You must set the fan control mode (off or manual "100%"). The Asus AI suite sometimes causes some problems ... You can find in this forum some similar issues. If You connect the cooler with the Molex to 4PIN Y splitter (link in my post above) than You will have constant 12V from Your PSU and feedback to Your motherboard also (RPM of one fan). Just open the link, there is explained how it connects. Connection:

 

1. CPU cooler connected to Your motherboard CPU header (3PIN connector)

- here You can apply the Y splitter and have constant 12V for Your cooler-

2. Supplied Y splitter connects to Your cooler CPU block

3. 2 x fans (PWM 4PIN) connects to the supplied Y splitter connected to Your CPU block

4. USB data link cable connects to the CPU block + USB 2.0 header on Your MB

 

additional note: in case You would like to use 4 fans, You connect these 4 fans with another molex to 4PIN PWM splitter to Your CPU block (to avoid built in fan controller overload). But this is another story, will not explain into details.

 

PS. Sometimes the CL software don´t reads my fan/pump rpm (0 rpm) after PC start ... i do a restart and everything works well (it´s not perfect, looks like some SW bug) - with fast SSD it´s question of few seconds ;)

Thanks Datakiller24. I changed the CPU fan control in the bios to MANUAL and that seems to have fixed things (70 deg / 100% 20 deg / 20%). I now have actively fluctuating readings on fans and pump. The pump and fan are now responding to performance changes from quiet to performance,etc.

 

thanks for the help!:cool:

Hi GUTH56,

 

If I understand properly, You have set up manual control in Bios according the temperatures ... what is not good :(

Now Your MB is changing the voltage to regulate the "cooler", but it´s not good for the coolers electronics (must be 12V continuously). Your manual set-up should be always 100% and the control of the pump and the coolers fans should be setup through the corsair link software. Please check it once again, needs to be setup once properly than You have just to enjoy :)

Hi Datakiller24, Yeh...CL decided not to work today - same issue - not responsive to performance changes and pump and pump fan stuck.

 

I took your advice and went back into the bios. Changed CPU fan monitoring to ignore. bios will not let me change MANUAL settings. I will attach screen shot.

 

Anyways, after changes same problem however, after some playing I found a way to get it to work (respond and show active rpm numbers). CL refused to change performance settings even if I changed to pre-saved files. However, if I go into the OPTIONS window and chose RESET to DEFAULT and then go back to the System window CL reverts back to presets and EVERYTHING WORKS and I can change performance settings!! I have done this a number of times. Each time no response on saved presets but upon reset to default everything works... well this program it is screwy for sure.

:cool:

ok, this is wired. CL using the "reset to default" is responsive to changes and shows active fan rpms... I now have 2 CPU fans: "H100iGTX Cooler fan" and, "ASUSTek Motherboard CPU Fan" they both respond to performance fan setting changes at the same time. Readings are close but not the same... (eq 1200 and 1197).

 

Well?:cool::roll:

Hi GUTH56,

 

What You see in CL is normal, as the MB is reporting to the CL also the fans RPM. The slight difference is ok (i have it also). To Your bios settings, You have to set CPU Q-FAN Control to disabled and You are ready for the constant 12V for Your cooler.

 

- i was experiencing also the problem what You have with CL, i have uninstalled, reinstalled, cleared all profiles from it. Than I have setup everything I would like to have than on the main screen (where the case is displayed) at the bottom saved the setting to my profile. From that time, it works well. BTW, I´m not changing and checking it everytime, as custom fan profiles set already, LED set already ... so I don´t need to go there :)

 

BR,

Thank you DATAKILLER24, I am happy with CL performance now. It does have problems for sure but is currently use-able and helpful since I can actively monitor all sensors including pump and make performance changes.

 

Here is what I have my BIOS set at for reference:

 

ASUS MB P8Z77 - V -Deluxe

 

CPU Fan speed : ignore

CPU Q-Fan control : enabled (must be enabled to allow for manual profile)

CPU Fan speed low limit : ignore

CPU Fan Profile : manual

upper temperature setting : 70 (default)

upper temp duty cycle % : 100

lower temp setting : 20 (default)

lower temp duty cycle % : 100

 

I also recommend "reset to default" in the "Options" window to clear the CL software. It seems to not work with previous "old" settings. I can then reset the settings and save.

 

Thanks again... G

Hi GUTH56,

 

You are welcome! I think if You turn off the Q-FAN CPU control in the bios will not happen anything, as the CPU header is used only to get the 12V from the MB and report back some fans speed (speed of Your radiator fan). All the changes done for Your pump and radiator fans are done by the built in controller of Your CPU cooler ;)

 

But, Your manual setup do the same, so You have full 12V all the time, You can keep it.

Now, as everything works well (except some bugs in SW) You can start to play with fan profiles to get the max out of Your cooler :)

 

BR,
