Starman007 Posted April 5, 2018 Share Posted April 5, 2018 Can anyone help! I have an H115i installed as per instructions....two fans connected to pump cables and pump cable connected to MoBo with PSU power also attached. USB Cable is also attached. Corsair link V. 4.9.6.19 shows one fan speed and pump speed and of course the Temp. The Problem: Asus BIOs refuse to detect this unit as a liquid cooler! I've tried plugging the pump cable into all three ports.....two fan & pump with no luck. Asus AI suite also doesn't pick up the pump, just one CPU fan speed which is lower than listing in C.L. I haven't tried placing all three cables onto the MoBo. Looking forward to any suggestions. Link to comment Share on other sites More sharing options...
DevBiker Posted April 5, 2018 Share Posted April 5, 2018 Neither Asus AI Suite nor the BIOS will "detect" this as a cooler. Unless it's the PRO series cooler, the fan speed reported to the CPU Fan header will be about 1/2 of the actual pump RPMs. Have a read through of the Liquid Cooler FAQ linked in my signature.

Corsair Employees Corsair Lettuce Posted April 5, 2018 Corsair Employees Share Posted April 5, 2018 Take a look at the device manager and see if 'Corsair USBXp Driver.' As DevBiker mentioned it won't state the name of the product. Link to comment Share on other sites More sharing options...
Starman007 Posted April 6, 2018 Author Share Posted April 6, 2018 Thanks for the replies. Corsair USBXp Driver is installed and in details shows Corsair H115i. The reason for concern is that the MoBo has warning leds that indicate a CPU problem and the only thing that I could determine that was wrong was that the cooling system isn't showing up. When trying to tell the BIOs that there is a liquid cooling system installed, looks like it would accept that as a fact!!! I guess that there's nothing that I can do except to change to Air cooling.

DevBiker Posted April 6, 2018 Share Posted April 6, 2018 What fan header do you have the pump fan connector plugged in to? This should be plugged into the CPU_FAN header. If it's not, you are likely getting a CPU fan warning. If you can be more specific about the details of what that "CPU Error" is, it would help a lot.

Starman007 Posted April 6, 2018 Author Share Posted April 6, 2018 The cable is plugged into the CPU_FAN header. This Board has four leds that light up on boot and stay lit if there is a problem detected....which my CPU one does. It does not tell you what the problem is, wish there were a log file. This is my first liquid cooling experience so I'm in a learning mode. Watching Corsair link while doing some processing (@ 40 to 50%) the CPU Temp jumps to the 60s C and generally stays there, Liquid Temp never goes above 30C. Is this a normal reading?

DevBiker Posted April 6, 2018 Share Posted April 6, 2018 It doesn't sound too far off. What's the vCore when you are getting those temperatures? If the cable is plugged into the CPU_FAN header, it should be providing a tach signal to the fan header. Do you see a CPU Fan Speed in the BIOS? And what does your liquid temperature start out at? It doesn't typically get very warm very quickly. Link to comment Share on other sites More sharing options...
Starman007 Posted April 6, 2018 Author Share Posted April 6, 2018 CPU Temp is listed. It's easier to show you what I'm seeing. The Working Temp is very near the start of processing. Notice the reading of Temp #5 on the board! Link to comment Share on other sites More sharing options...
c-attack Posted April 7, 2018 Share Posted April 7, 2018 Yes, this is normal. Think of the water system as a waste disposal for heat. It can get rid of it and move it elsewhere, but it cannot prevent heat from passing through the CPU pins to the CPU and then finally out through the cold plate and into the water stream. Turn on your stove and put a pot of cold water on top. The heating element will be too hot to touch within a few seconds. The water will take several minutes to get warm and longer to boil. The difference is the this water system has fans and a radiator to shed to the heat so you never get to that point. We know what happens when you heat the pot without the water :( Your baseline H115i Temp (coolant temperature) is the lowest possible CPU temp. So the colder you can keep the liquid, the greater the headroom you have for voltage based heat (like overclocking or just high normal loads). The general range of coolant temperature is relatively low and slow to change up and down. Again, it is like a separate compartment to hold and move heat to an exit point. As such, unless you are running at 100%, you don't need a lot of fan speed to get rid of the heat and keep a minimal coolant temperature. I often stress test with 1200-1300 on much heavier wattage loads than a 6700K. I can't see you needing 1100 for many normal loads and you might prefer to clock those down to something more like 700 at the expense of likely 1C of CPU temp. Even a small 120mm cooler is rated for more wattage disipation than a 6700K can create, however it would likely need high fan speeds to do so. The advantage of that 280mm cooler is you don't need the high speeds and can do it on surface area alone. On my 215W draw 5930K, I would never run my fans past 1000 for any type of workload and that still kept a coolant delta of around +6C. I would expect the H115i to keep your coolant at +4-6C. You might even see the highest marks when under CPU and GPU load. This is the result of the entire case warming up, not more CPU heat that a stress test. Yes, good ol' motherboard sensor #5. I don't know what it is supposed to be, but it is classically 0.0 or 127.9C on most Asus boards. Probably something in the embedded controller Link can't read. All the motherboard junk seems to be cleaned up in iCUE/CUE 3. Link to comment Share on other sites More sharing options...
DevBiker Posted April 7, 2018 Share Posted April 7, 2018 Hmmm ... one thing that I noticed was that you had a vCore of 1.39V ... in Link-speak this is "vCPU" (don't know why they call it that ... really should be vCore). That's definitely going to give you some heat on the CPU. So that's something that you need to look at. Are you running overclocked? If so, is your overclock on "Auto" settings?

snapper69 Posted April 7, 2018 Share Posted April 7, 2018 Have you tried plugging a case fan to the CPU_FAN header to see if that stops the error? Link to comment Share on other sites More sharing options...
