Open Hardware Monitor Reviews

Why I like Open Hardware Monitor:
This is one of the only apps I can find, other than SpeedFan and MSI Afterburner, that reads my GPU and CPU temperatures AND can put the values in the System Tray.

I can also put fan speeds, clock speeds, and any of many other values it reads in the Sys Tray. SpeedFan works, but crashes a lot for me. MSI Afterburner works too, albeit through a far more complex interface, and the (bitmapped/blocky/unscalable) tray font is hard to read. Open Hardware Monitor is small, straightforward, has an easy to read (and antialiased/scalable) tray font, and is easier to configure for novices. 5 stars.

Good and free open source but beta version for now.

I've been using this program for over 2 years now and my only issue is the very slow updates (which is not a real issue unless you have the latest hardware).
Other then that is an amazing little program; modular (unlike HWMonitor) and very light weight with all the proper options (start with windows minimized and so on).

Highly recommended.


Very functional and resource friendly

Having used several such programs even commercial products I am really impressed with Open Hardware monitor. Especially it resource consumption, while not extremely lean, comparative to other offerings it consumes on an x64 Windows 8.1 U 1 box less than 20MB of ram with the web service running at 1sec resolution and sub 1% peak CPU usage.

Additionally this application captures hardware data for the usual temperatures to NAND flash write rates and other unexpected metrics your hardware maybe generating.

Small non issue is that for external USB drives in my case it doesn't apply a name label to the device. Other than generic Hard Disk, it could well serve the user better to apply the volumes present on the disk make it easier to differentiate. As in, E:,M:\ If those two volumes are on the external disk in question.

This application could be significantly expanded or used as the foundation codebase if one requires a customized monitoring solution since this an open sourced product. Will be interesting to see if this product will go cross platform as its based on .net which will be cross platform in the next generation.

Great work, great future for this project I hope. Kudos to the developer.


Clean and Easy

I've been very happy with OHM. The main screen shows all the stats you can hope for and then allows you to easily select the important ones for either the task bar or the Gadget window. This allows you to keep an eye on things you're interested in while using little desktop space. I'm quite impressed at how clean the interface is and how little setup is required. The only thing I could wish for would be some kind of historical graph that would show the past minute or so.


There is a graph window that shows from 5 minutes to 24 hours of historical data. It may well have not been there when you created this review, but you can now access it under View -> Show Plot.


Thank you for providing this framework. I needed this to monitor my 10 RIG ( total 80 GPUs ). But i realized that i had to login to each RIG ( 10 times * 5 times a day ) = 50.
That is 50 logins thru Team Viewer or RDP in one day just to monitor 10 RIGS.

I took the code and extended it to log all the hardware statistics acquired to a SQL server database, every 5 mins, so that i can just look at this table in excel and find out which GPU's are running hotter then expected. It also logs other hardware info like CPU, Fan Temp, Memory usage etc.
