TIP: GPU Temperature and blowing out fans
Hi All,
A non-invasive way to check your Graphics processor (GPU) temperature and your CPU temperatu Speed Fan: http://almico.com/sfdownload.php A too hot CPU or GPU usually means your fan has seized up, or is full of dirt. If you blow out your fans, be sure to capture the blades to keep them from spinning. Fans are reservable electric generators and will send a current back to what it is plugged into and can also burn out your fan controller circuitry HTH, -T |

If you blow out your fans, be sure to capture the blades to keep them from spinning. Fans are reservable electric generators and will send a current back to what it is plugged into and can also burn out your fan controller circuitry The video cards that I've used with their own fans have their own fan speed control. Safer to let those cards regulate their fan speed than to let the user decide to run it slower. That is, the card already regulates its own fan speed so don't you try to unregulate it. Speedfan is still handy to regulate the CPU and case fans; however, again, the BIOS or software that came with the mobo might already regulate fan speed to reduce noise but will up speed to make sure the device gets sufficiently cooled. I use Speedfan but only to monitor GPU temperature, not to alter the fan speed the video card already self- regulates (and I don't need software to have the video card self- regulate its fan speed). It is handy for its charting: you can see how temperatures have fluctuated depending on your use of your computer. it also has a log but I've found the chart (for temperatures, fan speed, or voltages) gives me enough history to monitor temperatures as I change how I use my computer. Make sure to enable its option "Set fans to 100% on exit" to up fan speeds to full RPM when it is exited. You don't want the fans left spinning slower all the time when you play a game or do GPU or CPU intensive computing. Make sure you aren't using Speedfan against the temperature controls that may be available in the BIOS. It is more important to blow out the heatsink than the fan. Fans don't accumulate much debris (unless you have the computer in an area with smoke, like cigarette smoke or in or near the kitchen). Lint and dust accumulate in the heatsink's fins and reduce its utility. For fans, use an ear swab to scrub the dirt loose on its blades. When blowing out the dust, yeah, use the ear swab or a tooth pick (through a grill) to hold the blades from spinning or put your finger on its hub if the fan is exposed (when inside the case). Besides protecting the logic, a fan spinning because you're blowing compressed air across its means less of the air is getting blown into the heatsink. Remember to get those cables out of the way of the air flow inside the case, too, especially if any are the old flat IDE cables. Fans don't work so well trying to blow through a forest of cables. If you have a side panel fan, make sure it blows in the same direction as the CPU's fan. Having them blow at each other or away from each other means less air flow. GPU heatsinks can be a bit tricky to blow out their dust because often there is a plastic shell around the GPU, heatsink, fan, and maybe the memory. If you must use the mobo card slot next to the video card, make sure it is a half-length card that doesn't overlap where is the fan on the video card. Much harder to get air flow in a tight space and around obstacles. Personally I would not recommend using Speedfan to user-regulate the GPU's fan speed. Maybe on low-end video cards don't have speed self- regulation but the ones that I buy do. They'll spin down when not loaded and producing less heat and spin up when they get hot, like when playing a video game. I don't need software for that and shouldn't use software for that. The BIOS of the low-end mobos don't have much in the way of CPU and case fan speed control. The salvaged one I'm using at home only has a threshold alert, no fan speed control, so Speedfan comes in handy to quiet that computer but used only for the CPU and case fans and just monitoring the GPU temperature, and to provide alerts for all (if you define events to issue popups). Be aware to not accidentally change the CPU's fan speed to zero or some very low RPM. The BIOS will see the CPU fan speed is too low and shut down the computer. It won't wait until the CPU's temperature spikes too hot. Configuring Speedfan can be tricky because it can sense the hardware but may not provide easy-to-identify labelling. You might think you are setting fan speeds for the case fan but are instead setting them for the CPU. Once I figure out which sensor is for which fan, I relabel them in Speedfan. You won't find help, a menu, or right-click context menus to let you figure out how to rename the fans. Hit F2 on a selected fan under the Fans tab in the configuration screen. Seeing "Fan1 on IT8720F at $A0 on ISA" won't tell the user which fan it represents. If my mobo's BIOS had a decent fan speed control configuration, I'd be using that instead of Speedfan. I don't use Speedfan on a video card that already employs self-regulation. If the hardware can do it, don't use software. Speedfan is one of those useful tools *if* you know what you're doing with it. It is /NOT/ an install-and-go tool for boobs. Considering you come here getting help on how you can help your customers, you better hope you installing Speedfan on their computer means they never putz around with its configuration assuming you get it correct in the first place. |

Safer to let those cards regulate their fan speed than to let the user decide to run it slower. I only use it to check the temperature too. Ah, but that's the trick, isn't it. Fan speed on video cards is *not* set under hardware closed-loop feedback. The fan speed is set by the *software driver*. At power-on-reset, the fan register is set to "100%". If you boot a Linux LiveCD that doesn't happen to have a driver for the fan setting, the card stays at 100% fan for the entire Linux session. It sounds like a hoover. (Paul fixed this!!! Paul hates this!!!). It's also possible for NVidia to release a driver which writes "0" into the register (stopping the fan) and nothing more. This too is a breaking of the feedback loop. Nvidia pulled this driver relatively quickly, but at a guess, some video cards must have been damaged. I think actually a couple of drivers, over the years, were released with this particular defect in place. What I did to the video card in this machine sitting next to me, is: 1) Run demanding video apps. 2) Measure fan speed that results. 3) Disconnect fan from video card. 4) Make up a voltage source that runs the fan at the same speed as (2). Now, the card no longer relies on an NVidia driver or a Linux driver or any driver. I can boot a Linux LiveCD with a VESA driver, and the video card makes the same amount of noise as it does in Windows. I can do this because the card is low power, and the moderate fan speed used, is of no consequence... other than to guarantee the chip doesn't get too hot. High power video cards, have occasions where the fan must run at 100%. The fan on this card, handles everything at only a 20-30% setting. There's really no need to change the fan speed, ever. ******* The video card companies should do two things: 1) Implement a proper hardware closed-loop-feedback fan control. I'm not aware of any card doing that... yet. 2) Implement THERMTRIP for the GPU. If the heatsink falls off the GPU, the GPU should be able to send THERMTRIP to the Volterra "disable" pin, and drop the core to zero volts instantly. I'm not aware of any video card that has the capability to "protect itself". They will get so hot they melt the plastic fan frame, then the GPU will laugh at you as it overheats further. The closest thing to a self-protecting chip, was the ATI9800Pro. If you didn't plug in the Aux power connector, a red dialog box would appear on the screen, telling you to plug in the power cable. That's how I determined the card had burned right through one of the Aux power pins one day. I got the red dialog. That's an example of defensive design, where someone went to the trouble of storing a canned image, to be loaded if the card wasn't powered properly. Other than that, video cards are rather poorly equipped for the real world. It's almost like they wanted them to burn out. Paul |

I hear it's a great toy but the stale information spooks me. On newer boards, I believe some sort of ACPI table was added, which allowed the motherboard developer to pass the value of the scaling resistors, to people like the SpeedFan developer. As a result, the SF no longer needs a table of motherboards. Older motherboards, yes, if they hadn't been added to the table, manual work would be needed to get the scaling on the voltage values done correctly. An older motherboard still relies on the manual method, if the motherboard isn't in some table of previously-collected empirical results. But with newer motherboards, the SF guy doesn't even have to know the motherboard exists. Probing the buses, reading the ACPI table (whatever table it is), is supposed to give enough info to get the job done. It relies on the motherboard developer "encoding" the information correctly. Why, the motherboard developer could use his copy of the existing SpeedFan, to verify it all works :-) ******* Just the name in the example here, hints at how it may be working. It looks like all the sensor info is available as an ACPI object. The "atk0110" thing is the Asus hardware "punch-thru" driver that gives hardware access from a running OS (solves the Ring3/Ring0 problem). https://www.linux.com/learn/discover...hardware-linux $ sensors atk0110-acpi-0 Adapter: ACPI interface Vcore Voltage: +1.23 V (min = +0.85 V, max = +1.60 V) +3.3 Voltage: +3.31 V (min = +2.97 V, max = +3.63 V) +5 Voltage: +4.97 V (min = +4.50 V, max = +5.50 V) +12 Voltage: +12.15 V (min = +10.20 V, max = +13.80 V) CPU FAN Speed: 3183 RPM (min = 600 RPM) CPU Temperatu +44.0C (high = +60.0C, crit = +95.0C) MB Temperatu +40.0C (high = +45.0C, crit = +75.0C) Using the ACPI dumping utilities in Linux, you may be able to spot how it's being done.

I think it knows how to read from certain _chips_, if they're on an appropriate interface; I hadn't registered that it _had_ a list of suitable motherboards, but I'm guessing it works with more modern ones as long as they have chips it can talk to. If you only use it for _monitoring_ temperatures (and possibly fan speeds), and dismiss any obviously wrong ones (0 RPM, or -40 degrees, or possibly even sensible temperature but doesn't change), then it's probably safe to use (though I take no responsibility if it isn't!). I just use it for temperature monitoring. There are (or were last time I looked, which was many years ago) other utilities that could read temperatures; not sure why I chose SpeedFan - I think just that it seemed to work well, and as someone else (Paul was it?) mentioned, its graphing of them is handy.
