    Corsair GS600 TTC-103 thermistor alternative?

    I have a Corsair GS600 PSU that switches on and produces all the right voltages. However, when the psu starts the fans spins, but then never spins again until the PSU shuts itself down - overheating.
    The fan is designed not to operate the fan below 40 degrees C, but I have traced and open circuit TTC-103 thermistor and am looking for an alternative/replacement and cannot find a reliable source in the UK and I don't have the skills to confidently specify an alternative myself.
    Any thoughts?

      Here is the data sheet for this part number

      http://j5d2v7d7.stackpathcdn.com/wp-...emperature.gif

      Try this if you have a 5k ohm pot and see if you can get the fan to turn ON ( start 4 k ohms and either increase or decrease the resistance to turn on the fan if not then this might not be your only problem

      You can also buy a temperature sensor controller for fans on EBAY they are not that expensive if you can not figure out what wrong with the circuit

      Hopefully someone on this forum can explain the information on this data sheet because because I do not understand the specifications for this device


      I hope this helps you

          Thanks very much! It proves that I need to think a little more.
          I didn't have a suitable pot but with a little trial and error I have the fan spinning with a 1K resistor. I think that it also proves that if I can find a replacement thermistor, the power supply will be up and running.

              Can not find Model/Value of Thermistor.
              by nmbb
              Machine: Autoclave.
              Brand/Model: SANYO MLS-3780
              Manual: (Sorry search option not working on this PDF)



              Hello guys, this autoclave running with 2 thermistors already connected TH1 and TH3(on CN1,CN2 sockets). One for the water temperture and second one for chamber temperature. But there is another emtpy socket for optional third thermistor CN2 wich is for TH2 for object temperature. I wanna add the third thermistor TH2 to CN2 socket. But i can't figure what model/brand/value i need to use. In manual document, there is no info about TH1 and TH3 model number...

              Random Shutdowns/Startup Failure with Corsair SFX 450
              by h0m3w0rk
              Hello everyone,




              I'm encountering a frustrating issue with my Corsair SFX 450 power supply. After an undefined period of operation, my PC will either suddenly restart or, in some cases, it won't start at all until I disconnect the power cable and reconnect it. This erratic behavior occurs intermittently, making it difficult to pinpoint the exact conditions under which it happens.




              For context, I have tested the PSU using an electronic load at 150W, and under those controlled conditions, it functions flawlessly. This leads me to...

              Corsair TX650W fuse, NTC thermistor, and (APFC? Power Transistor) fried
              by socketa
              I read through this thread, and just want to confirm what i should do.
              https://www.badcaps.net/forum/showth...hlight=24N60C3.
              This person's fault was exactly the same as mine, even down to the power strip and with the muffled popping sound.
              I suspect that my problem started with an old power strip, of which a computer and a 2000W heater were plugged into...
              I noticed melting and heat where the heater was plugged in, so i plugged the heater directly into a double wall socket, but still noticed the muffled pop sound when i turned on the computer, and...

              Magic chef oven - thermistor ref voltage issue
              by Use2bavolvo
              I am having an issue with my wall oven temperature control is ~180f out of spec. The thermistor is measuring correctly but I noticed the ref voltage appears to be off. With the thermistor wires attached it's reading ~3.4vdc with the thermistor disconnected it's around I9.8vdc. my understanding is the temp is read off the resistance from the thermistor which leads me to believe the issue is with the ref voltage.

              Another observation is the temp setting and readout at lower temps is way off meaning the oven thinks room temp is 300f and bake relay doesn't engage unless temp setting...

              Sony KDL-40BX450 LCD. Thermistor gets too hot 10 seconds after turning on the TV
              by Quantum IC
              Hello every one,
              This TV came to me with the problem that it was totally dead.
              The problem was the two MOSFETs and a fuse resistor in the power supply.
              The original MOSFETs were KF7N50F and I repalced them with SLF65R700S2.
              The original fuse resistor was 0.1 Ohm 1/2W. I didn't find a similar fuse resistor and I replaced it with 0.1 Ohm 5W ceramic resistor.
              When I plug the TV the ST-BY LED turns on, when I press the power button on the TV, the ST-BY LED turns off and the TV doesn't turn on until the second time I press the power button is when the TV turns on,...
