content: Hello all.I've been working with my new Rigol scope for the last couple of days, and have found that one thing in particular stood out whilst using it... That damn noisy exhaust fan!I have a Noctua 60mm fan on order, and intend to replace the stock one once it arrives in the mail. The only problem I'm seeing at the moment is that of the default connector on the motherboard of the scope is one I can't identify, and more importantly, isn't the standard 2.54mm/0.1" that comes on PC fans.Would anyone who's replaced the fan themselves, or knows more about molex connectors than myself be able to identify this thing so I can buy a replacement part for my replacement fan?I'd just cut the one off the existing fan, but for the sake of retaining my warranty, I'd like to be able to replace the original fan if I ever needed to return it to Rigol.For reference, here's the connector type:Taken off another eevblogger's fan replacing post.Thanks everyone

content: It's likely to be PHR2 by JST. The terminals are SPH-002T-P0.5.

content: Just by looking at your photo, I would say that most of the noise comes from the grill stamped out in the metal.

content: You could cut the original cable and reuse the connector from the original fan.

I was only able to find the BPH-002t-p0.5 terminals, they look identical, but would they work with the phr2 connector?Thanks very much for your inputAs for the grille causing the noise, it undoubtedly plays a part in the problem, but I'm sure that running a much quieter fan will also make a difference, as the one that's in this scope is a ~6000 rpm screamer, and it doesn't even put out much airflow. The Noctua fan I'm replacing it with has higher cfm rating, and runs at a much lower rpm, with a 17 dBa vs. 30-something dBa rating.I would just cut off the cable, but I'd like to be able to claim the warranty on this unit if something ever went wrong, and would have to replace the original fan to do that.

content: I replaced the fan with a Nocuta NF-A6x25 fan and it is brilliant. The original fan was a little noisy, then I tried the Xilence 60mm fan and it was same if not louder than the original. (Mind I only paid about £6 for it). So I got the Nocuta - for about £12 delivered. What a night & day difference. Highly recommend this fan. I just cut the original fan wires and installed a 2-way motorcycle connector so I can easily interchange the fans if required. The Nocuta comes with 2 filters, ultra-low and low... I am not affiliated with Nocuta in any way.
