Fan Speed Temperature Controller

[Tmt97]

Can someone explain to me how these work? I like the idea of having a fan controller that can control itself based on temperature, but still has knobs for manual control if needed, but I don't get how they know what the temperature is. Anyone know? Thanks!

Those controllers basically manually let you vary the voltage to control the fans as DC voltage control and has a temp probe on a lead to let you monitor temps from that probe. I would personally suggest units like the NZXT Sentry 3 which are a touchscreen unit and a bit more trustworthy. I've purchased stuff from them before and they take a long time to ship but are decent.

Banggood is actually a very reputable source to buy things

So how does the temperature probe work? And does that mean that it just displays the temperature but it isn't automatic in changing the speed?

Ones like theses are fully manual the temp probe is just to give you a reading nothing more, if you want something that is capable of fully custom fan curves based on temps the NZXT Grid+ V2 is your best option other than using your motherboard directly.

My DIY fan controller is always a solution, but you need to solder and setting the "fan curves" is not exactly user friendly

Thanks for the tip! I would use the motherboard directly, but it has hardly any fan headers.

You can control the fans speeds in the BIOS but if you need more headers you can use splitters, usually a good rule of thumb is 3-4 fans per header to not overload them.

If the motherboard has PWM headers, and you use PWM fans, you can use a powered hub and connect as many as you want (within reason)

 

If they are not PWM, do not exceed about 1A total per header.

I've been looking at cheap splitters too. Just thought I'd look into some of these since they had more features like reporting back the temperature on an LCD and stuff.
