Last weekend I had to replace a 230 V fan (120 mm), a Sunon DP200A, that ‘smelled’ strange and also made strange noises. Better safe than sorry…
Well: I ordered a slightly less powerful Sunon DP201A (at Reichelt Elektronik) to replace the possibly dangerous fan. Although they look similar their connectors are completely different. So I’m now wondering if the first one (the DP200A) wasn’t an original fan at all…?
