Hi guys.
I'm now facing a new problem.
I use jbl mpx 1200 amp to drive my passive subs.
Amp was bought some 7-8 years ago from a friend and tech , with the fan disconnected. Reason was the noise.
He told me he would do it , and that i wouldn't have any troubles.
Well a few days ago i had to take it for service since one channel was not working at all , and the other had developed a wooing noise.
Thankfully the hybrids were ok , and only the electrolytic caps all of em were changed.
Ok amp is working fine.
BUT the noise from the fan that was reconnected is unbearable. To much noise. That is at first or second stage. I don't want to imagine what will be on the third stage. It is a 24vdc fan 120mm wired by two cables.
I was thinking of changing it to a NOCTUA , but the only noctua heavy duty with enough airflow is a 140mm that will not fit.
Any ideas?
Thanks in advance.
