Recommend a quiet 50mm fan?

I appreciate that small fans are not clever for delivering silent cooling, but size is not an option. I have just replaced the fan on my Toshiba RD85 HDD video recorder as it was intermittently making imminent death noises. The choice locally was limited, the replacement part has a higher specified current and makes far more flow noise. Checking on specs via the internet, the outgoing Tranyoung/Cofan 5025LL12S 12V fan has a very low 2500rpm operating speed and 14dB rating (still delivers 8cfm, recorder is rated at 35W so not a huge task - another application for this particular fan is a rack mount server) and I can't find anything that matches it - even Scan's Fractal Design fan is rated 5dB louder. Temporary replacement is 12cfm @ 5000rpm. Any recommendations for brands or UK suppliers that might be a solution?

50mm is an awkward size, PC case fans tend to be 40, 60, 80, 120mm so you might struggle for choice
