timbo2410 Posted January 2, 2016 Share Posted January 2, 2016 I've got this cooler on my Asus Maximus viii extreme. The fans I have connected to my PWM controller on the case (Phanteks Enthoo Primo). The pump I have connected to the mobo "pump" input. I have set the pump speed in Asus AI Suite 3, to be constant and maximum. This turns out to be 860 rpm. Is this speed correct ?

Toasted Posted January 3, 2016 Share Posted January 3, 2016 That is quite low, can you disable fan control in the BIOS or run the pump at max speed? If you are still seeing 860 RPM, try a different fan header and see if anything changes. Is the reading from the BIOS, the LINK software or SIV? How are your CPU temperatures?

Pokemon Posted January 3, 2016 Share Posted January 3, 2016 My pump is powered from a sata connector and the 1 pin connector is in the CPU_FAN1 and it runs at 2700 speed...its like that by default,i didn't do anything at it. Link to comment Share on other sites More sharing options...
timbo2410 Posted January 3, 2016 Author Share Posted January 3, 2016 Ok I've looked in bios to check and the pump is under direct control at 100% output and the speed is saying it is 860 rpm. If I put it in manual at 100% it is still maxed at 860. I have the H110i fans going into my PWM controller on the case, I have the usb connected to the mobo usb header and I have the "pump" connected to the "pump" header on the mobo. Temperatures are 18-22 degrees C at idle and reach 52 degrees C with the overclock (4.6Ghz on Skylake from stock 4.0Ghz). That's using Asus realbench with 100% CPU usage and I have also run OCCT, CPUID-Z, 3D Mark and Prime95 with the same temperatures. So I think the pump is running at maximum but the RPM is not correct. The RPM in AI Suite through the OS is exactly the same as in bios. Link to comment Share on other sites More sharing options...
c-attack Posted January 3, 2016 Share Posted January 3, 2016 I would agree the pump is not running at 850. It's likely that isn't even possible. Most pumps have a 60-70% minimum duty cycle which would be about double that reading. It could be software or polling error, but it seems a little consistent for that. At least you can be reasonable sure the system is cooling well while you try and figure it out. Unfortunately, I don't know enough about how Asus has wired these new Water Cooling headers to offer a suggestion beyond trying it on a CHA_FAN header with the same manual 100%/Full Speed BIOS and AI suite settings to see if there is a difference. Just be aware when you run 100% on a CHA_FAN header, the Asus quick fan presets in AI Suite (Turbo, Full Speed, etc.) will override the 100% duty cycle.

timbo2410 Posted January 3, 2016 Author Share Posted January 3, 2016 Yep I'll keep looking for the answer. In a way it would be good if it were reading low as that means I can overclock higher and still keep good cpu temps. At present I have resisted installing Corsair link and have just used the Asus bios and AI Suite to alter fans and pump .. I wonder if the speeds would read differently if I used Corsair software instead .. but in the meantime I'll keep looking for the issues ..

red-ray Posted January 3, 2016 Share Posted January 3, 2016 The H110iGTX reports the fan speed to the CPU_FAN header. The only way to know the pump speed is to use a utility that reads this via the USB connection. The third party utilities I know of that can do this are AIDA64, HWiNFO and SIV. They all need you to install the drivers that come with CL. If you don't wish to install CL then you can get them from http://forum.corsair.com/forums/showthread.php?p=823034 I would agree the pump is not running at 850. It's likely that isn't even possible. The Asetek pump speed range is about 780 to 2,580 RPM. Link to comment Share on other sites More sharing options...
timbo2410 Posted January 3, 2016 Author Share Posted January 3, 2016 so if I install corsair link will it effect the Asus software at all? I could not find any drivers on that link ?? Link to comment Share on other sites More sharing options...
c-attack Posted January 3, 2016 Share Posted January 3, 2016 Possibly. However you can minimize the polling conflicts by keeping only one active at a time. After you install LINK, you can set it not to run on start up. Then when you want to change pump speed, LED lighting, etc., launch it, make the change, then quit the application. It is supposed to retain it's settings without the software running, although it's a little strange your pump would be bottomed out straight from the box. I would have expected the opposite. You can do the same thing with AI Suite (launch, change, exit), however at this point you are probably using it quite a bit as you get a feel for the system. Also, even when set it to run on start-up, AI Suite doesn't appear to start polling until you make the window active from the mini-bar. Once you do that, you usually need to exit to stop the any erroneous readings. It also will retain the current fan profiles. Link to comment Share on other sites More sharing options...
timbo2410 Posted January 3, 2016 Author Share Posted January 3, 2016 ok just installed CL and I've just managed to look at the water pump rpm :-) .. it was sitting at max rpm so that's good .. but it does mean that I am at the limit of cooling :-( On the up side I just changed the "CORSAIR" LED to RED .. so that's gotta be worth something ... however I thought the cooling abilities would have been a little better .. thanks so much for your help BTW :D: Link to comment Share on other sites More sharing options...
red-ray Posted January 3, 2016 Share Posted January 3, 2016 Possibly. I expect it's 100% an issue. If you have both AI Suite and CL active at the same time there will be conflicts. AI Suite fails to use the Access_ISABUS.HTP.Metho named mutex to interlock access to the motherboard sensors so sooner or later the **** will hit the fan. You should either have CL active or AI Suite active but NEVER both. Link to comment Share on other sites More sharing options...
timbo2410 Posted January 3, 2016 Author Share Posted January 3, 2016 ok so I've made changes in CL and will not access it again. It's not running in the background either so fingers crossed :-) Link to comment Share on other sites More sharing options...
Pokemon Posted January 4, 2016 Share Posted January 4, 2016 You are not at the limit with cooling,that pump has to work full speed all the time so it recirculates the liquid inside.From there,the fans do the rest,if needed they will speed up accordingly with your temperature.

timbo2410 Posted January 4, 2016 Author Share Posted January 4, 2016 since I downloaded CL the pump speeds have been accurate (2880 rpm) according to CL. However, in bios it is still reported as 860 but it is still set in manual at 100%. Yes I did also note that if I changed the fans to "silent" in Asus AI Suite 3, then it would also change the pump speed so I have to be careful with that. I also noted that the temperature reported by the Asus front panel and bios is not the same as when checked with speedfan, realtemp or OCCT and other software. At idle Asus is reporting 22 and speedfan is reporting 18. Ambient temperature in the house is 19 so I think asus is closer. On the high side things are different though. Asus reports maximum temperature of CPU (using realbench stress test) as 58 while all other software reports it as being 62. Don't really know which one is accurate ??
