3 Pin Fan Hub

Recommended Posts

Posted · Original PosterOP

Hey, So I recently bought the Deepcool FH-10 fanhub and quickly realized that my 3 pin fans won't be able to be controlled through it. All I want to do is control my 3 pin fans through speedfan, they don't need to change depending on temperature or anything and I also don't need to control of all of them separately, for example let's say i get a fanhub that if i change the speed on 1 of them it changes all of them, i'm completely fine with this.

 

Is there any fan hub for 3 pin fans that can do this or i'm i out of luck?

to be able to control your fans speed I believe that you need a 4 pin fan. Three pin fans don't have pwm control which is what allows you to control the speed of the fan. I could be wrong but I am pretty sure that is how it works unless if you can get a 3 pin to 4 pin adapter not really sure though

You can control 3 pin fan speed but it's a lot less accurate. Usually 12V gets the fans to run at full speed so if you were to send 7V to it it would run at 70% speed. PWM fans always have 12V going to them but their motors aren't running all the time.

3 pin fan - DC control

4 pin fan - PWM control


Things I need help with:

Spoiler

 

 

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

 

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

 

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

 

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

 

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

 

Personal Blacklisted Companies:

Spoiler

Acer monitors, Gigabyte, Seagate HDD, Kingston SSD, Razer (except their mouse), XiaoMi Phones

 

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

Exactly. I've been able to control the 3pin fan speed using openhardwaremonitor, not sure about all of them at once.
