Repairing a Yamaha keyboard

So my family's keyboard had a few keys that didn't make sound when pressed. It is not a good keyboard in the first place (though it did accompany me or mostly my bro to various performances and competitions) and very old (>10 years), so I didn't want to repair it. But my mom was asking me to.

So on a free day, I took it apart to try my luck.

Back to being silentpcreview.com-approved.

I had to do some things to the HD5670 to achieve this though:

 

HD5670, 92mm fan edition.

And then undervolt the HD5670 to 1.0V @ 700MHz. The HD4770 could do 0.9V @ 675MHz.

NZXT Havik 140 CPU cooler - User review - Special pseudo-fanless edition

I never thought I would get my hands on an NZXT product. NZXT is famous for its chassis and case fans, typically aimed at the silent computing enthusiasts. I also am a silent computing enthusiast, but I never spend on expensive casings and fans. I have never spent on CPU heatsinks either since I got the Ninja in early 2006.

And it happened that I won a contest (or is it more of a lucky draw?) and got myself a NZXT Havik 140 CPU cooler. And being a number-hunter, I promptly proceeded to test it.

Measurements

I finally got around to measuring this amp. And building the contraptions needed to measure amplifiers.

It is July, but I typed June, because I tested the June drivers and the July drivers were not out yet.
