Developer’s Description

By Open Hardware Monitor

Monitor temperature sensors, fan speeds, voltages, load, and clock speeds of a computer.

The Open Hardware Monitor is a free open source application that monitors temperature sensors, fan speeds, voltages, load, and clock speeds of a computer. It supports most hardware monitoring chips found on today's mainboards like the ITE, Winbond, and Fintek families. The CPU temperature can be monitored by reading the core temperature sensors of Intel and AMD processors. The sensors of ATI and Nvidia video cards as well as SMART hard drive temperature can be displayed. The Open Hardware Monitor runs on 32-bit and 64-bit Microsoft Windows operating systems without installation.

NOW THIS IS HOW IT IS DONE
Independent521December 17, 2014
Pros
Clean Simple Meets the need No malware
Cons
NONE AT ALL
Summary
Folks this is how software should be written. NO BS, to the point and meets the need. Where can I give this guy some money!
Simply and useful
vesstovesstoApril 2, 2014
Pros
Portable and light.
Cons
No default values for temperature so users to know if they reach the max safe level.
Summary
Nice and useful program, perfect for free and beta one.
Displays temps/load/speed of GPU, CPU, HD, & Bus speed.
mkzynskiAugust 24, 2012
Pros
- Easy to read/sort through explorer like window with pre-named hardware. - Displays min/max/current temperatures/speeds of individual cores of the processor and graphics card processor. - Displays min/max/current temperature of the hard drive. - Displays bus min/max/current speed. - Can also display graph over time of different statistics as well. - Has completely customizable space saving gadget that you can enable instead of the window that you can add or remove temps/speeds/etc, make it smaller, drag and drop gadget size and position. - Seems to be extremely accurate/instantaneous readings.
Cons
None that I have come up with over the last year I've had the program.
Summary
Simply the best free program for keeping tabs on temps, speeds, etc. You will not regret having this program on laptops or PC's. Great way to monitor your temps. I love the gadget option that just has a nice little window with temps I selected. I always keep it in the corner of the desktop.
Handy display of Parameters

Pros
Easy to download and install. Runs off of flash drive.
Cons
No indication of fan presence or fan speed on my laptop.
Summary
Downloads, installs, and runs easily but the lack of fan information on my laptop limits its usefulness for troubleshooting.
Great little utility. It does just what it promises.
lrleonMay 5, 2012
Pros
It does not install in Windows. This means that all what is required to run it, including the dll's, are located where you decide to keep it. Very informative, fast and small.
Cons
To install and use Open Hardware Monitor some technical knowledge is required, very little indeed. This software is not installed by Windows as most other software. It displays a lot of technical information that you need to understand (but this can be solved just by googling anything you want to know).
Summary
The only one that showed temps, without Admin rights...
scottls59901April 21, 2012
Pros
No permanent installation, and w/wo Admin showed the same info on my system (everyone's system is different...). I've tried "several" different freebies, and None showed CPU/HD temps (blank).
Cons
Could NOT find " Open Hardware Monitor " on a cnet Search (after opened), but " Open Hardware Monitor cnet " shows on a Google search? Cnet Please fix, so others can more easily find it!
Summary
Win 7 (32), i5-2500, Intel DH67BL MBO, WD Raptor Sata6 10K rpm HD (WOW!- faster than my old C300 SDD, using free Defraggler full defrag/replace... (must also Disable Win auto-defrag schedule!)). This app shows "most everything", and extra info would be Very useful to Gamers/OC'rs (cannot OC i5-2500, but it's has Turbo-Boost 3.67ghz (like it Much better than old i7-2600, and like a video card better than on-board video!). I Was looking for what made the "Loud" whining noise coming from my Antec 300 ATX desktop case, and thought it may be temps (Not?)? Turned out that I Was defragging on 1st cold startup. Not the first time I've had problems with installations..., on a cold startup. Also I find system/net... is Much faster, if I do a no-activity reboot 15min after cold startup.
Excellent Product
primecipherApril 8, 2012
Pros
Simple, easy to use, many more features than the competition.
Cons
Commit size is not tiny, but I really haven't found any true cons yet.
Summary
I recommend this product.
Great Monitoring program when run with Admin rights
gqmracerx7March 24, 2012
Pros
Gives CPU voltages, all core temp/speed/load, fan speeds, GPU temp/speed/load/fan, and HDD temps. Very low overhead to run program. Can hide items I don't want displayed. Rename labels for what I want them or if they have generic labels.
Cons
I haven't found one yet.
Summary
Run it with Administrator rights so you see all the voltages/temps/etc. From the other reviews I saw I think they were missing that step. Worked great for my OC'd i5-2500K and GTX 460.
great little program
butchiezJuly 16, 2011
Pros
tells you about your system hardware fans temps and stuff
Cons
not really easy to figure the report out without a little more then a regular computer user knowledge
Summary
it is okay will show exactly whats up if you can read it
Perfect FREE option for constant monitoring.
Windows3-16March 24, 2011
Pros
Shows temps for all hardware with diodes. Includes 'widget' that displays any values you want constantly on the screen in a black 'winamp' style window, which is what I was looking for. Widget has transparency options. Only uses 1% of CPU or less.
Cons
None. Be nice if it showed memory load too but that's a nit pick.
Summary
Everything you'd want from a temp monitor. Just download it.
