So the initial testing results for L3+ with Manrose fan are in. Before I was running my overclocked L3+ at about 1000W with a fixed fan speed of 20% and the highest chip temps were aboout 77C with 70dB. Manrose fan without any adapters just put next to miner on intake with nothing on exhaust 64C max chip temp and 65dB.
I have not tested D3 with this fan but with a custom firmware and settings it's also running at 1000W so I guess results should be similar. S9 temps are higher but it can also tolerate higher temps so you could go for 6" fan or just accept that temps are higher and use 5" fan. Well they are not cheap @ £60-70 but they will have re-sale value as well if you need to sell them. Another conclusion is that exhaust fan does not do much on Antminer so you might as well ditch it for the 2C temperature difference and save up to 36W of power usage worth about £2.88 per month.
