Rerurn to Romy the Cat's Site

I was replacing transformers in the Super Milq HF channels and while I was doing it I decided to perform a minor maintenance on the amp.  One of the amp’s fans developed a “flat” in it bearing and created a very minor “step”. I order a replacement fan, also this time I decided to mount it differently. I ordered the very same fan that I used before, the most silent that I was able to fine 2 years ago.

To my surprise the very same fan tuned out to look very different: the same price, the same box packaging, the same model of course only slightly differently looking blades. It was SilenX 120x120x25 12V fan with 1100RPM at 11dBA. So, I put the new fan next to the old fan on my table and tune them on. The new one is twice more silent! Hm… how little I need to be happy!

Also I abandoned to mount the fan with screws and fan rubber gaskets. This time I just dumped on the amp’s wall the black silicon that I used everywhere (mentioned above) and glued the fan to the amp via 3/8” of the silicon. The result of the new fan and new mounting is fantastic. When the fan is on, at full 12V (never happen) then my stethoscope pick absolutely no events on the Milq’s chassis. Very-very cool!
