There's no need to buy hddfancontrol - ssd fan control is free/donationware and works a treat using the S.M.A.R.T. data from the SSD. I've used it on mine and many other iMacs, download from here: http://exirion.net/ssdfanctrl/ You'll also need a caddy to convert the SSD to 3.5" - the basic little tray that for instance Crucial sell is not good enough and leaves the SSD hanging on one screw. Buy something like this one: http://www.amazon.co.uk/dp/B00F3QFKNS

My Panasonic Microwave was really easy to fix. On the bottom there's a metal panel that is almost punched out. It's hanging on by a couple of metal tags that can be cut with side cutters (wire cutters if you like) Simply snip these on three sides and bend back the panel to reveal the turntable motor. Take out the couple of screws holding the motor and it falls out. Replacement motor costs less than £10. I just taped the metal cover back down with some aluminium duct tape. You could use large (short) self tapping screws to do the same.

IMPORTANT: there’s a spring under the post which could go anywhere when the post comes out with the screw.

Only two screws as stated above need to be removed but as people have found out, the one in the cowling can bind into the post below it and it’s the post below that unscrews instead. So you end up with the screw+the post+the fan all together as one. That assembly can be worked out, and then with two pairs of pliers the post and screw can be separated.

The lower right T6 fan screw is a standoff (that also secures the logic board). This can be loosened and kept with the fan, or (since it is friction captured in a grommet on the fan), the fan can be lifted off, being careful not to dislodge the grommet.

The HDD Temp sensor is just a NPN transistor - in the past with SSDs I have used a 2N4401 - connect the grey wire to the emitter and the black wire to the other two pins. Works a treat.
