MF01 Mini / MT07- Mod/Upgrade - Copper Heatsink Cover Plate

Okey, thank you man of light!!!

If you happen to have an extra, I will take it
Thanks, Steve

2nd batch is full now, but I will continue to collect interests (post #2) for the case somebody jumps off or the supplier will be able to deliver a few more.

Hi

I’m interested for 2 for the 2nd or 3rd batch.

I’m interested in one. Thanks

Mine arrived today. Thanks!

Now to hunt down my thermal paste…

P.S. Make sure you dig the isolation stickers out of the package. I forgot and nearly threw them away.

I’m interested in one. Thanks :slight_smile:

1 pcs. I am Interested

Thank you very much, man of light, this is a good job!

I'm Interested for 2

Please put me on the list for another 3. There is a deal on banggood for 41€ and I completed the gang. Now I got every color……

Hello. My name is Muk and I am a flashoholic……

I got my light yesterday and my heat sink today. The heat sink works perfect and renders great sustained output. Thanks a lot M O L!

As a side note. I used Arctic Paste and not thermal pads and I could not be happier with the results. Significant improvement! :+1:

Interested in 1, thanks

A bit late, I know…. but would be very interrested for 1.

Thank you

The copper heatsink arrived yesterday. I applied the isolation stickers and slathered the areas specified in Post 1 with thermal paste - Cooler MasterGel Maker Nano - Cooler Master MasterGel Maker Nano Review | eTeknix The copper heatsink slotted in precisely.

A few hours later, I switched the light onto max ramp. Three minutes later there had been no step-down - still on max ramp - and the copper head of the light was noticeably warm.

Thank you, Paul, for all your work developing a workable solution to this design defect and making it available.

Having built a few hundred personal desktop computers starting in the 90s the thermal paste choices now have never been greater but you should choose carefully for your flashlight ones that have good heat transfer properties and are not electrically conductive.

The best heat transfer is always metal to metal surfaces but metal has minute pores where air resides.Air will also be trapped between uneven surfaces and in tool marks.Air is a poor conductor of heat and needs to be replaced with the heat conductive thermal paste.Use only enough to replace the trapped air and not so much that it flows past the edges of the chips.A small dot in the center of the chip will spread evenly once pressure is applied.On a 7135 chip extremely little is needed.

Some pastes take a few days to cure while others are good to go upon application.

A very good non electrically conductive carbon based paste in the 2019 version of Arctic MX-4 and it's reasonably priced.An application can last for years.

If there is no surface contact between the chip and the heatsink themal paste alone may not be enough and use of copper foil to fill the gap may be needed.

On my PCs I carefully use Thermal Grizzly Conductonaut liquid metal that's 8X better than anything else but it's highly electrically conductive.

Thanks for your feedback and input guys, nice to hear for me and helpful for others :+1:

For all who expressed their interest, I updated the overview list in post #2. I will keep you up to date as soon as there are some news on availability. If there is enough interest I will realize a 3rd batch.

Thank you for your helpful input, some has already been discussed here, I mentioned the Arctic MX-4 in my post # 1 already right from the start, its a good one :+1:

Yes, Arctic MX-4 2019 version worked amazing on mine. :+1:

Hi! Interested in 1, thank You.
