Dan,
?
That¡¯s interesting, according to my manual (05335-90021 4th ed, Aug 1988) the fan is a 3160-0209 32CFM 105-125V 50/60Hz.? We¡¯ve fixed several of these and they have all had AC fans.
?
Might want to check again, on the other hand there may be a different version we have not seen that is DC.
?
Regards,
?

Subject: [HP-Agilent-Keysight-equipment] HP5335A fan replacement
?
I want to replace the fan in a used HP5335A, which is very noisy. I Googled this topic and did not find anything here, but found a suggestion on the EEVBlog. One poster suggested using a?Noctua, NF-R8 (), but this is a 12V fan and my HP5335A fan is powered by 24V.
So, I bought a Evercool 24V fan from Amazon (). The specs for the?Pabst fan that comes with the HP5335A are:?34 dBA, 61 m3/hour. The specs for the Evercool fan are: 28 dBA, 55 m3/hour. So, the Evercool is a bit underpowered, but considerably quieter than the?Papst. From what I have read the?Papst fan is a bit?over spec'd in?terms of airflow, so I thought the Evercool fan might work fine.
Does anyone have reasons why the Evercool would not be a good replacement fan? (Joe, KN5U - any comments?).
