s5 Fan Modification

[xmatt007x]

Hello Team!

I would like some guidance on fan modifications. I have recently purchased a S5 and I would like to learn how to replace the default fan and add a secondary fan for push/pull. Is this easy and just unplugging the fan and replacing it? Does the Antminer have a power input for the default fan and a secondary fan? What other tips do you have to make the unit run quiet?

Edit: Does the unit also shutdown if it gets too hot?

Thank you!

there are lots of threads on this, for example:

personal experience: noctua 3000 works in push together with ultrakaze in pull (put ultrakaze on constant fan using molex directly from PSU)

Total expense ~$40, miner is much quieter, but temp of the boards will rise to ~58C (with 28C ambient), which is still OK-I run them like this for months.

You'll also need some long screws, I forget the dimensions but it'll be in one of the 3 or 4 S5 threads if you search for "screws".

yeah, long metric screws, good point...check in lowe's metric screws section if you are in US.

Thanks for this information! Would one fan connect directly to the Antminer and the other would be constant using a molex connector?

Does the S5 auto shutdown if the unit gets too hot?

You could make a power stage for that second fan and use the same pwm and speed signals than the default fan. That way it is still tmp-controlled. Power-stage looks very similar than original S1-S3 design and it's pretty easy done on an external PCB.

It is supposed to autoshut down at 80c, but you should keep the miner at 60c or lower anyways. If you want another failsafe that is not software based use something like this;

I somehow dispense with the additional screws. I use 4 screws coming with stock fan, 2 angularly for push fan and 2 for pull fan.

i swapped mine out for quieter operation to 3000rpm noctua fans, ive always used lower rpm noctuas in my pc builds with excellent results, anyway turns out bad idea, operating temps significantly higher than the stockers so I've changed them back. I've considered running the noctuas as pull, but the stock fans blast a fair bit of air through and i'm not sure if itll overspeed the noctuas

[mavericklm]

i don't understand why ppl don't try to duct 2 or more quiet fans thru a miner

What do you mean ?

temp up to 59C are fine-it makes no difference-i run Noctua push/ultrakaze pull(at molex=full speed), miner was at 58-59C with 28C ambient (higher than most folks)
