Hi Ian,

if your Y-splitter is only providing the power to the fans, and not sending back the RPM signal, then you wont get an RPM reading on the motherboard.

Yeah, that's just it. The Y-splitter goes through the EVGA AiO pump housing. The cable is 4 wire coming from the housing and 4 wire that plugs into the motherboard header. One of the fan connectors is 4 wire while the other is only 3. I have no idea if there is any circuitry in the pump housing that controls the fans.

I have a couple new PWM fans that I ordered. I'm gonna re-do my fan setup and eliminate a non-PWM exhaust fan since I'm limited on fan headers (time for a new motherboard me thinks?). I'll see if that helps next week when I get the fans. :)

Thanks for the idea Ian. :)

Have a great day! :)

When running more than one fan off a 4-pin header the reporting of fan speeds is almost certainly going to be a "work of fiction" as the fans are not synchronised with each other. The best you can hope for is to know what fraction of full-scale the PWM control signal is set to, and trust that all the fans are running at that fraction of their maximum speed.

Most splitters solve this by only sending the RPM signal from one fan.

Hi Ian,

Ok, so this explains why the 2 fan connectors on the Y are not wired the same. One has 4 wires the other has 3. I'm thinking that having the 2 connected through the pump housing is the problem with my 0 RPM reading. I'm thinking that connecting to the motherboard headers directly will solve that. Or, perhaps I should have ordered a Y cable too.

Thing is, I don't have a "CPU fan" per se. The power cable for the pump is 3 wire and is on the AiO header.

I do have another fan header, it's for the M.2 fan. I'm not sure if there is a difference between that and regular fan headers. The manual doesn't go into it. The fan mount is small and fits fans the size of those on the Pis. The Noctua fans I got for my Pis are 5V. Case fans are 12V, correct? Ok, I answered my own question, well, not the voltage question, but using the M.2 fan header. No can do. It runs the fan at a fixed RPM. I suppose I could use it for the single 3 wire exhaust fan. Then I would have 4 PWM headers. Sounds good. Now I just need my new fans. :)

Thanks Ian and have a great day! :)

It might help to just directly state what motherboard and AIO CPU cooler you have. or post pictures.

Usually with AIOs if it's supplying power to the radiator fans, wont report the fan speed to the motherboard because its using its own internal controller. this information is usually accessible from the software for the AIO, which will get the information from the USB connection on the AIO itself (and the software probably only runs on windows anyway). So if you want reported fan speeds in Psensor, you'll probably have to connect them directly to the motherboard as you already are starting to think about. I would probably keep your splitter, and plug it into the CPU fan header on the motherboard, powering both fans from the single header. It will only truly report the fan speed of one fan, but they will be spinning roughly the same speeds if the fans are the same.

I'm not sure what an "M.2 fan" is. M.2 is an interface for SFF NVME SSDs and other pcie devices. fans don't connect to this.

There is a github project that has the drivers for all the popular Asetek AIO coolers for Linux. It enables you to control the pump speed and set the fan speeds on USB connected AIO's. I have used it and it works well.

Hi Ian,

I'm not sure what an "M.2 fan" is. M.2 is an interface for SFF NVME SSDs and other pcie devices. fans don't connect to this.

Asus Prime Z370-A motherboard
EVGA 280mm dual fan closed loop cooler M# 400-HY-CL28-V1

Asus came out with a mount for a small 40mm or 50mm 12V fan for overclocking purposes. The thing is, their directions for mounting the fan put it nowhere near either M.2 slots. It's up by the CPU power connector. My one M.2 drive has a heat sink covering it with a pad. Yeah, I don't get why they say it's for M.2 drives. The M.2 fan header is down by the drive covered by the heat sink, opposite end of the motherboard. No way can air flow through the sink. Perhaps it's just a gimmick.

Yep, I do have the fan situation figured out. I'll do as you mention and keep the 2 radiator fans connected to the CPU header. Just need the new fans... :) Will post results next week.

Have a great day! :)

Hi Keith,

You're kidding me, right? ;)

Sure, I would love to have a Linux AiO controller software. You gotta remember, I'm a noob when it comes to Linux. I can use Package Manager or Synaptic no problem. That was how I installed Psensor this morning. I'm a caveman when it would come to something like Github. AND, especially if installation would require doing it from source code. I haven't a clue how to compile in Linux. And frankly, I don't think I would want to.

My temps are down in the low to mid 60s. That is very respectable. Maybe someday, If I get a wild hair... maybe I'd try compiling source in Linux. But not today. ;)

Have a great day! :)

It is normally as simple as downloading the git package or zip file and unpacking for most packages. No compiling necessary.
Then:
make
make install

Hi Keith,

Why is it that developers of software for Linux assume that EVERYONE knows ALL the ins and outs about installing?

I got as far as unzipping the zip file. I assume that to use "make" there must be a "makefile". Is that a correct assessment? I seem to remember something about that from WAY back in the 90s when I was playing around with programming in OS-9 (Unix like) on my Color Computer. Or perhaps it was in the early 2000s when I decided to play around with Linux and BSD... Yep, just confirmed it on the Internet, make needs a makefile to COMPILE SOURCE CODE! I've been through all folders in the unzipped folder and there is no makefile. I don't even see anything that looks like source code. Perhaps I downloaded the wrong zip file? The one I downloaded from the download button was "liquidctl-master.zip.

K.I.S.S.! If it ain't broke, DON'T fix it! Perhaps I should just leave well-enough alone. It's been running just fine without any controlling software for the pump and fans. But then, how can I learn more if I don't fix what ain't broken? ;)

Have a great day! :)

My comment was in response to your comment that one must know how to compile in Linux to use any program. Just not true. No there is no makefile in that repository since all you have to do is follow the instructions to install all the various bits needed for the application which is Python based. So a few python installations are needed first.

The make command is used to run the makefile as you surmised. But not all programs need to be made. Depends on the complexity of the program and whether the developer has already done that for you and packaged up the bits already to run. If you don't EVER want to run make I suggest you stick to the pre-packaged and compiled installers like snap, flatpak or appimage.
https://askubuntu.com/questions/866511/what-are-the-differences-between-snaps-appimage-flatpak-and-others

All that is needed to understand Linux is to do a bit of reading or ask questions.

You can also look in the /docs directory in the project directory and read the readme for the x41zc application for suggested command lines. Class of cards listed is rather outdated but so is the app.

There are no errors in BOINC Event log or windows event logs. However in the the \slots\n directorys I am seeing the following errors in stderr.txt

recheck your drivers to make sure they have OpenCl and that windows didn't install it's own during the night. Restart BOINC and look at the first 30 lines of the event log to see if the OpenCl component is there.
