Regarding fan replacement, I'm looking at Sanyo Denki 9RA1212H1001 which is slightly less powerful than the stock Panaflo (~14% less air flow and ~10% less static pressure) but 8.5dB less noise.
However, they are a bit expensive at €37.
I've seen people suggest Noctua NF-A14 iPPC3000 or Nidec DC1225CB6/B7 in the thread, but the Nidec models are not easy to find and I wanted to avoid an adapter for 140mm fans (also the Noctua is only 4dB less noise than stock Panaflo).
Has anyone used other fans and how did they work out for you in terms of temps?
Often the temperature are even not shown on the service GUI. So hard to compare.
I went with the Nuctua & required 3D printing adapters. It is less load but still as a load hoover and requires good cooling. Each old fan is about 1.5kg.
I addition I reduced the two aluminum plate sizes, so easier & faster to handle in case of front panel re movement (as clean-up & Encoders to replace). In addition the 5...7mm black foam have to be replaces as I used afterwords a softer one.
Anyway, the LeCroy DSO was not a masterpiece how to build an easy maintainable / service able gear. Almost the front bezel as a nightmare as requires replacement but 3D printing not able to get equal bezel color.
Happy tuning.
