I don't know why you made a new thread for this...

If your replacement fan does not spin as fast as the original fan, you will still have an error

You must use a fan with similar specifications or the miner will still assume than fan is faulty. I doubt your desktop fan spins as fast or moves the correct amount of air.

If you are in a pinch and only have 1 good fan, assuming you have low ambient temps, you can re-flash the s7 to the 1 fan s7 firmware and run it a slight slower frequency so you can get by untill your new fan arrives.   if it runs hot then keep reducing the frequency untill its stable. this is a temporary solution. When your new fan arrives go back to original firmware.

This only works for later batch s7's and not the early 54 chip variants. If it is an early batch s7 this 1 fan s7 firmware will not work.

no sorry i didnt write well maybe. this time it is not a desktop fan. it is an original delta fan made for thousands of rpm.
Still weird thing happen when i start. the new fan only starts when the miner starts to mine after about 2 min. the old fan starts as soon as i press the on button on the PSU.

Also i only have place for one fan on the miner. It only came with one fan. are you saying thereshould be 2 fans? could it else be the I/O board thats is wrong?

got it to work now. The problem was there should be 2 fans and the one who sold me it only gave me 1 fan. I got him to give me another fan and when i have them both it works. very weird because there is no fan mount on the backside i have just taped it there with duct tape.
