Speedfan-like controller for rad fans?

post #1 of 5
Thread Starter 
Is there any kind of controller out there that works just like speedfan, yet controls fans plugged into the controller as opposed to the motherboard? The problem with all the controllers I have found is that they rely on tape-on thermo sensors. Ideally, I'd want something that would get the CPU temp off the motherboard (like speedfan does), then control my radiator fan speeds based off that.

Anything out there like that? I suppose one option would be to just use speedfan and run the rad fans off the motherboard fan connectors so speedfan could control them, but it I think its a bad idea to run a ton of fans off the motherboard like that (I will be running between 4 and 8).

I use this thing and love it.

amongst many many other things it allows me to import the readings from speedfan and set multiple profiles. So it imports the data from speedfan and controls the fans using it.

Also works for my pump, lights etc etc. i have a temp sensor on my loop, a few hidden "sticky" sensors as you call them and the temps from speedfan all plotted to a curve. Temps go up, fans rpm go up. Four channels make it pretty flexible, running 6 120mm fans off one channel without a problem.

Also great for monitoring my pump, giving me ample warning of sudden change caused by it stopping or a leak etc. Previously had a pump die and the first thing i knew about it was the thermal cut off.

Thanks for the reply. I had seen that T-balancer before but didn't see anywhere in the product description that it could read the temps from speedfan. When it talks about it having "digital sensors", is that what its referring to? IE the stick-on sensors are analog and the digital sensors are pulling from speedfan?

there are analogue "stick on" sensors and digital ones. the digital ones are very accurate and the analogue. well not so much.

Here are the two software sets working together, i have just added one value from speedfan here. speedfan is just seen as an additional source of data. it supports other programs too.



This is the same value being used to plot the rpm of the fans




This is an analogue sensor i attach to the controller to get a picture of the water temp.



Using one or two "stick on" sensors is a good idea as it gives you a difinitive temp for that area, especially the digital ones as apposed to the "rough" calculation using distance to tj max that speedfan etc give. also cool for measuring ambient which gives you a better idea of how your cooling is performing.

alphacool heatmaster, cheaper than t-balancer. enough power to run two laing ddc. reads temps from onboard (motherboard, cpu, gpu) temp sensors = no external sensors.

yeah rly!
