OK, I will check it out. These are the fans I tried, but they only have 3 pin. The 4 pin looks very large, but I will trust your suggestions.

one of my S3 fans totally died. 0 RPM. on the fan it says model number JDH1238B I had a 3 pin 2000 RPM fan but won't fit because pins are larger and 4 pin. Any advise for me to fix or buy? Send it back to China or cut the connector?

You need a 120mm PWM fan, which has a 4 pin connector. While waiting for your RMA, you could fit a Corsair SP120 high performance fan. If you do, I would put the Corsair on the inlet and your good Bitmain fan on the outlet. I've been running my S3s with these fans on the inlets from the outset. Got them from Amazon.

The only thing I had to do to make it fit was trim off the little plastic rib from the middle of the 4 pin connector on the fan. I mentioned this fan because it's an easy and quick fix, but if you try it make sure you get the PWM version. They're on the pricey side, though, so I would definitely check out bspurloc's Dell fan suggestion first, as it might be the best option.
