S17 fan speed?

[tangy_t]

I'm looking to replace some fans on a S17. ZeusBTC had this on their fan replacement page.

6000 RPM Miner fan: used for Antminer S9, V9 and L3+

5000 RPM Miner fan: used for Antminer L3+

7000 RPM Miner fan: used for Antminer S11 series, S15 series, S17 series, and S19 series.

After seeing this I realized my fans never go above 6k, with 5800 being the most on 2 of them. Seems the 7k fans pull 5A is  this safe to run on  a s17? I vaguely remember coming across a post on here about someone frying a control board by putting 5A fans on a asic.. just cant remember which asic it was from bitmain.
If I'm able to go full 7k fans, I will, currently eyeing HVVH 5A 7000RPM fans on amazon right now. https://www.amazon.com/HVVH-5A-Brushless-Replacement-7000RPM/dp/B08QZV3YM1/ref=sr_1_1?crid=30FF8D6HST669&keywords=7000%2Brpm%2Bantminer%2Bfan&qid=1646523573&sprefix=7000%2Brpm%2Bantminer%2Bfan%2Caps%2C169&sr=8-1&th=1
Any other suggestions for US resellers?

The 12V supply on the APW9 can only handle 12A, so 4 fans at 5A each isn't going work.

RPM isn't really the most important thing to look at when selecting fans. The fans on an S17 have to push air through hundreds of heatsinks, and that resistance creates high static pressure.  So the maximum static pressure spec and max flow are more important things to look at.
