temperature sensors

[Sham65]

hi i have a Scythe Kaze Server fan controller and i have the 3 temp sensors stuck to my 360 rad at the same place and they give me different readings 30.1, 31.2, 30.4, i have it on auto but my fans dont sync because of the different readings, my question is, is there a way i can make the temp match on all 3 channels, i thought maybe a 2 pin to 3 x 2 pin whould work so i could use one sensor for the 3 x 2pin that are on the back of the scythe, but cant find a product to do this, any ideas ??

you could split the signal from the temp sensors, are these the 2 pin ones?
I haven't tried but I guess it could work.
Otherwise dont be surprised, temp sensors of this quality are only within +/-1C accurate

hi yes they are the 2 pin ones, i have 2 spare ones which i might cut and join to make 2 x 2pin to one sensor and see if it works, if so ill join 3 together, im not to bothered about how acurate the temp reading is just whould be nice to have the fans all sync on auto, i tried joining 3 fans to one channel but it went a bit crazy so i put them all on separate channels, its a shame they dont put some sort of calibration setting on these things or does that sound stupid

you should be able to tune each channel for speed vs. temp to account for it

hi, yeh tried that but they still dont sync, i tried lowering one but it stays on for ages while the outher 2 go off, maybe im being to fussy but whould be nice to have all the fans go off at the same time

Just split the + and - of the temp probe into 3 wires each and connect to the relevant pins on the fan controller.

BTW your sig is disgusting reminds me of Bubba the Hut

That's because I am funny that the wife says I remind her of him going to try and split the wires tomorrow see what happens

analogue sensors are not accurate and never will be. you need digital sensors for the best accuracy . some thing that uses the dallas temperature probes.

E.g we run a crystalfontz and 16 probes in one of our test rigs and were tightened them into to 0.1c accuracy. How ever its not some thing you can stick direct on a CPU as there too big.

ok i split the wires and joined them together and all three temp sensors are reading the same temperture, now all the fans turn on and off at the same time if i want them to on auto, i am now a happy bunny

edit: should have said happy Bubba
