Minimalist Loop Information

By Aethrios
The skin I threw together to monitor the different temperature and speeds present in the custom watercooling loop I recently built.


Here's what you're going to need to do:
 - Download HWiNFO here:
 - Install, make sure to run it at the end
 - in HWiNFO, go to:
Program -> Settings
Make sure you check "Shared Memory Support"
Make sure you check "Auto Start"
In some cases, you may also need to check "Show Sensors on Startup" if it doesn't automagically begin reading the values you want when your boot up your computer tomorrow.
You can minimize HWiNFO to the tray at this point, we shouldn't need to work with it anymore.
 - Go to where this skin is installed (typically C:\Documents\Rainmeter\Skins\Minimalist Loop Information)
 - Keep going, \resources\HWiNFO\resources\HWiNFOSharedMemoryViewer.exe
 - Find the sensors you want to monitor.
Are your rad fans plugged into your CPU header, or a chassis one? YMMV here, as it depends on how you physically wired up your build.
 - Once you find the sensors you want, navigate further down in this skin to the values you want to change, and make sure they match up to the information given o you by HWiNFOSharedMemoryViewer.
 - Save
 - Refresh the skin
 - Enjoy

Thanks to the Rainmeter and HWiNFO community, and JSMorley in particular for his more exhaustive guide, here:…
Thanks to billstelling for providing a cleaned up version of the original images used with the base skin

Change Log:

Corrected image paths (credit: Wimball)
Massively reduced filesize
Cleaned up smaller images (credit: billstelling)
Larger images
Fixed GPU image, removed colormatrix
Added tutorial
Consolidated plugin dependency to only HWiNFO
Skin pushed to standalone edition

Hi, thanks for your work.

I've followed every step on the instructions and made sure HWiNFO is running and the IDs and Instances are the same on the sensors and on the skin .ini, but can't get my rainmeter to show any values.

Anything that might come to your mind?

Thanks in advance

I just had the same problem... you also need to install the HWiNFO Plugin for Rainmeter then magically they appear :)

it can be found here :

Not sure why the skin doesn't work after I reinstall my windows system.

I checked all the steps. I checked Shared Memory Support.

I'm able to get the value under HWiNFOSharedMemoryViewer.

But the skin was not able to show it.

Any steps wrong?

Thank you!

I got the images to work by renaming the "Hardware Small" folder in resources to just "Hardware". That's the folder the .ini is looking for.

Great catch. Updated and credited. Thanks for pointing that out!

Hi it's working perfectly fine for me, but the images aren't loading. Look at the attached image.

Go ahead and download it again, or supply the fix Wimball pointed out: In the @Resources folder, change "Hardware Small" to "Hardware" and they'll load in after a refresh.

Does this work on Win7 64bit ?

Should, assuming you get HWiNFO working. I haven't tested it personally, I don't have any Windows 7 machines anymore, but I don't see why not. Let me know what you find!

Is it me or are only one of the images (GPU) in the Big Folder actually bigger?  The other ones seem to be the same...
Aethrios's avatar

They're the same size (30x30), but they are the only images not from EK. The rest were pulled directly from their site, after chatting with a rep. Since they didn't (and still don't, to my knowledge) have an in-house GPU waterblock logo, I snagged another.

Not sure what Im doing wrong but I cant seem to make it work. I cant get the images to show up, or the sensors to work.

It looks like you're passing the HWiNFOEntryID as a variable? I would check to see if you can plug it in manually first, and see if that makes a difference. It's hard to know more without seeing how you're passing them around.

As for the images, make sure the paths are correct; the default assumes you're storing them in the #@#Resources folder. If not, then you'll need to edit that too.
How do you measure the temp at the reservoir? and what does the numbers other than the temperature mean?
Aethrios's avatar
I have an inline sensor to measure the water temp. Mine is made by Phobya, it was only ~$15. 

The pump and rad measurements are their respective RPMs, and the CPU is temperature (C), and the GPU is fan speed (RPM)/temp (C). 
Im having some problems, i did all the steps, but the icons for the cpu, gpu, pum and the others dont appear. I don really know how to find and put the sensor in the right way

Sounds like two separate issues. For the images not loading correctly, can you tell me where you've got your Rainmeter skin folder (should normally be C:\Documents\Rainmeter\Skins)?
So long as your Rainmeter is installed normally, everything should install correctly - that's the perk of having my skin packages as an .rmskin, after all.

For the sensors, you're on your own. I don't know how your motherboard is configured, and it'll be different for every board. What I can do is point you back towards the link in the description. It'll take you to the Rainmeter forums, where there is a much more detailed guide that should help you out (step 4 specifically, which deals with how to use HWiNFOSharedMemoryViewer). Take a look at the whole guide, and make sure you follow it all the way through - it's exactly how I set things up on my own system.

Once you've gotten the SharedMemoryViewer up and running, then just edit the skin. I've put all the instructions you'll need in there as well.
I had tryed again from 0 again and I have the same problem, please help.

In the HWiNFO settings: make sure you have Shared Memory Support and Auto Start checked.

Navigate to where the skin is installed (typically C:\Documents\Rainmeter\Skins\Minimalist Loop Information).
Open HWiNFOSharedMemoryViewer.
Scroll down to the particular values you want to track (water temp, fan RPM, etc). Click on them, and keep this program open.

Edit the skin. In the Measures section, change HWiNFOSensorID and HWiNFOEntryID to the appropriate values that correspond to the values you want to track (again, water temp, etc).

Save and refresh the skin.

It really is that simple. If you've done it right, then you should be all set.

Failing to update the skin with the values that correspond to your particular computer, with your particular motherboard and sensor setup, is crucial to having the skin function properly. This isn't just a plug-and-play kind of skin, since everyone runs a different setup.
Men I need help, i did all the steps, but when i go to "\resources\HWiNFO\resources\HWiNFOSharedMemoryViewer.exe" It say "Failed to connect to HWiNFO. Please ensure is running, shared memoriv is raning nas sensors are active". I'm prety sure that I puted on all that it need but still happening the same Fail.

Please help me, I'm w8ing your answer.

It looks like you've skipped step one. Download, install, and run HWiNFO, as described in the guide above. Ensure you change the relevant settings.
I?m sure that i did it man :/
Very nice, I made a few small adjustments and this is exactly what I needed for my new loop.
