You will have to remove the fan, and look at it motor-side up.
There may be a blue dot with two thin wires leading into the PCB below the hub cover.

I do know that, but I don't have the time nor patience to do it.
And the gap here is really small, unlike what I did to my 92mm Datech which also had a thermistor.

I'd rather just get one that doesn't have this annoying 'feature'.

Remove fan, motor-side up, look near the middle.

It either has to be removed.
Or you have your fan mounted the wrong way (sucking air through the fins and blowing it out the top).





For the rest of you guys, if you have full-Aluminium sinks, quit looking. You'll either get a Delta or Foxconn on those, and most of the time they're equipped with thermistors as well.

That's interesting, because if they now come with Nidecs I'm going to buy X6's for all of my customers now.

Or rather, the next 2 customers.

This is what came with the 1055 that I just bought brand new. It came with a Delta and there is no blue dot on the PCB near the wires.

So did you get a Nidec or a Delta? I'm confused?

Anyway, Delta doesn't use those thermistors.

They use these:

i took a picture of it


it may not be blue but that sure is a thermistor sticking out of the fan.

on my 1100T BE.

Sorry, I got a delta, and my pcb looked the same as your pic but I ahd all 4 wires going in, not just the 2 thick ones.

Just checked my 555 be fan and it doesn't seem to have a thermistor and uses 4 wires. It's a Foxconn PVA070E12N model though so I dont realy know if that's the thing you are looking for... let me know if you need pictures biggrin.gif

Now that got me curious.

I don't have much experience with AMD CPUs and thought they used only PWM fans in their cooler fans. Why the added thermistor ? Is it to react faster to temperature rise ? Isn't this more costly ? Why does AMD use this system and Intel doesn't ? Or does it ?

My 1055t had a Foxconn with a PCB mounted thermistor. I cut mine with wire cutters and shorted the contacts with a very tiny piece of wire. Then I used SpeedFan to control it as well as shut down the PC if RPM dropped below 4,000, or temp went over 60C. I chose a 4k RPM shutdown because mine usually ran about 3.5k with the thermistor intact. If your mod gives out, fan speed will drop immediately.

No matter what kind of thermistor, PCB mounted or the little bulb/blob thingy, you can short it and the fan will run at MAX.

If your not up for cutting and shorting anything, which is harmless BTW, just flip the fan upside down. It causes the thermistor to read incorrectly and within a short period of time the fan will run very fast. Not 7k, but pretty fast.

If you dont have a soldering iron, and you have the PCB mounted type, cut the thermistor with a razor or small wire cutters. Then use a VERY tiny amount of super-glue to place a short piece of bare wire, or a very shor piece of paper-clip wire across the contacts. If you dont solder, I HIGHLY suggest learning how to use SpeedFan to shut down your PC in the event of fan failure. I ran mine for over a month with a glued wire and then sold it to another user on OCN (yes, he knew of the mod). Never messed up for me.

Yes, because yours is PWM and this is just a regular fan. However if it looks like that, it definitely has a thermistor. That part sticking out of the PCB.

Foxconn fans have the thermistor located underneath the strut. It's not entirely visible.
Not wanting anything but AVC, and I'm asking for information.

I would love to buy fans off you guys but I can't because shipping itself costs more than the fans.

Intel does. Maybe not in their new LGA1155/1156/1366 chips, but they were used extensively on LGA775 P4HT's and PD's.

This is probably another measure to try and shut the fans up, but it isn't working due to conflicting airflow that arises from using a stock cooler.

I know all that. But I don't want a mod. I have no time, and I'm screwed if it screws up.
I need plain, un-modded fans with no thermistor and coming that way from the factory.

Thanks for the write-up anyway.
