![]() ![]() This PCB has been designed so you can use a single resistor or a 100k potentiometer, i recommend using the 100k pot as this is far much easier to fine-tune this device for your needs. 2 x Latching Pin Headers 0.1″ Pitch 3 Way.One of the resistors is an NTC thermistor (temperature-sensitive resistor), while the other is a normal resistor. Only three components are needed to allow the fan speed to be controlled according to the actual temperature: one adjustable voltage regulator (LM317T) and two resistors that form a voltage divider. This not only saves energy, but it also reduces fan noise. A simple circuit can regulate the fan speed according to temperature. In most PCs, the fan runs constantly, which may not be necessary. Temperature is sensed using a simple NTC thermistor. It regulates the speed of the FAN attached to it according to the measured temperature. If you know when the period is that your HDD will increase, then you can plan for it.This project is a temperature controller for a PC FAN. The only annoying thing is that I need to manually adjust it, but I'm happy to do that. It may not be the best solution and it may have unnecessary RGB, but it allows me to control the fans. I usually like to find the most eloquent solution, but this is the most stable compromise I was willing to live with. ![]() I set these fans to run at a constant speed, where the drives stay a comfortable temperature. For drive (and general case) cooling, the basic rule of thumb is to blow air onto drives where you can, and have at least one fan exhausting heat from the case (near top of case, as heat rises). So for me, it was not worth the effort.īest solution is to allow your motherboard BIOS to control your fans. There are work around solutions that have been offered, but the risk is if they don't work correctly, it is possible for all of your fans to stop running. Enough so, that the few who would try have eventually just abandoned their efforts. The documentation for these chips either is incomplete, or non-existent, making it a frustrating headache for folks who try to write Linux drivers for them. The main issue (especially for Ryzen systems) is that there are a number of different models of the Super I/O chips used on motherboards by the different MB vendors. I traveled down this rabbit hole last year, when I set up my server. I installed the Dynamix System Auto Fan plugin and the Nuvoton NCT6687 Driver but the Controller still isn't detected. This seems a bit more complicated than I originally thought. I am trying to set the system up so it will adjust the fans based on the HDD temperatures. I don't think you need a fan controller.just better fan placement. More than happy to help you should you need assistance with fan placement or recommendations. I've never really had to worry about using a fan controller (hardware) outside of a gaming system.so if you're having issues, you should rethink your fan positions in your case. Larger fans (120mm or 140mm) push a bit more air at lower RPM's and in my case, it reduced the noise level of the server while dropping the temperature. This causes all my air flow in the hard disk section to be segmented away from the CPU side.all of my disks dropped about 10 degrees. I then put in a bunch of HUGE fans.one pushes, one pulls.on the hard drive side. ![]() ![]() I bought a new case.a Fractal Design Node 804.this case splits the motherboard/CPU/GPU from the Hard disks. I can tell you what I did to reduce my HD temperature. Keep in mind that you set these items in BIOS for profiles.and generally, fans will increase their speed based on temperature automagically. Plenty of options for hardware fan controllers but I don't think you need one. Ive seen it go up to 47 degrees during Parity Check. Generally the HDD stays within 30-40 degrees Celcius on a warm day. Buy CORN 5.25 inch PC Fan Speed Controller Temperature Display LCD Front Panel with fast shipping and top-rated customer service. Can you offer some suggestions? The only time I have seen the HDD temp go up is during a Parity check. Best Fan Control Software for Windows Fan Control and System Monitoring with Argus Monitor Fan speed control based on all available temperature sources, like HDD/SSD or GPU temperatures. Is there something I can purchase to add to my system? I'm not that knowledgable about how the system can get the HDD temp to control the fan speed. ![]()
