since my Tf1260 is in a tower I'm finding that thermal tape is not keeping the heatsink on stable..after a long period the heat sink starts sliding down so I'm thinking of installing a silicone heat sink compound instead of the thermal tape. Does anyone have a better solution for this?

You can try that:

@ HigashiJun

Thanks that looks like a great solution for my Tower👍

The fan linked above is 5V, IMO adding and inductive load to the already crowded 5V rail on your accelerated A1200 isn't ideal.

The fan header on your 1260 provides a 12V supply. You can of course connect a 5V fan somewhere else e.g. a floppy splitter or your Solas™. However connecting to the 12V header provided on the 1260 will allow you to utilise the underused and underappreciated “fancontrol” application from the TFTools pack matching your current TF1260 firmware.

Here are some design files for a big box 1260 (and probably any other 060/040 based card that isn't overcrowded with high rise components around the CPU) fan bracket that you can order up from your favourite fab (JLCPCB).

The top plate allows numerous nasty budget 12V (55mm bayonet mount spacing) fans to be used as well as Noctua NF-A4x10 (with a bit more work) for those of you who wouldn't taint your Amiga with such substandard items :)

It is a sandwich design that uses a "filling" layer between the 060 and socket to mount a top plate and fan. It also has the nice side effect of allowing the 060 to be easily and safely removed from the socket using an old toothbrush or other non marking implement when you can't find your expensive PGA puller :)

See the attached images for a small selection of the cornucopia of fan possibilities.

Here are some links to some (12V) fans that will fit :

Noctua NF-A4x10 FLX, - Wherever you prefer to find one. (Requires countersinking underside of the Alu top plate and mounting with countersunk 8/10mm M3 bolts + some M3 nuts and washers.)

Please note that this bracket solution won't fit into your standard A1200 case but can be used in towers and other big box 060/040 solutions.





Ordering information is included in the last two images. Be sure to note the base material and the PCB thickness specified for each. JLCPCB now only offer black or white finish Aluminium PCBs with black charged at an excessive premium for small batches. (Order the white). The sandwich layer PCB should be 1mm thick.

Yes, that fan is rated for 5V and intended to be connected on a 5V pin.

@ go0se

Wow some great options there thanks :D I agree better to go with the 12v onboard the TF1260 to spare the 5v line and alos use the fan control with my Alpha firmware (I'm assuming it can control the fan speed or possiblly automically adjust fan speed to temp etc?)

Fancontrol can turn the fan on or off, you have to use values 0 or 1, and that's about it.

simple enough...I'll be setting it up as soon as my CPU fan gets installed

We tried PWM control but this ended up being more complicated than i wanted. Some fans stalled unless they were moving first etc etc

Concerning the link I sent in my previous post, you can also remove the 5V fan from the heat sink and replace it with a Noctua NF-A4x10 FLX.

You will then have a 12V fan with a 3 pin connector.

Longer screws will be needed.
