KMPKT Heatsink Discussion

[Damascus]

I already have an l9i and l9a, I think that this kmpkt heatsink will become a proud member of my LP cooler family

 

[Kmpkt]

Very much hype. Pictures?

As much as my heart wants to see pictures, my brain reminds me that the same concerns about IP and patenting are probably still in effect.

Unfortunately this. I don't want to bury another 3-4K into patenting only to find out the thing is a lemon. While simulations etc. are super positive, nothing matches real world testing.

Oh, I had forgotten about that. I'm sorry.

I'll be patient!

 

[Kmpkt]

Will likely test it without heatpipes this weekend so as to obtain an idea of how effective various heatpipe configurations end up being.

 

[ECHO]

This is awesome news! I really do hope it pans out for you - we'll all be winners

 

[Kmpkt]

Couldn't help myself. Just need to get the pipe bending down and tap the heatsink and we should be good to go!

 

[Kmpkt]

Yeah F bending heatpipes by the way.

 

[Damascus]

Yeah F bending heatpipes by the way.

How did you do it? I've yet to be even a bit successful on mine

 

[Kmpkt]

I used bending springs from Home Depot. I manage to get four functionally bent pipes that I may end up using, but I've bought a pipe bending tool and second set of pipes to try out as well. Considering the amount of hassle it has been to get the prototype this far I really don't want to fuck it up on the home stretch by pooching the tapping or the pipes.

 

[ECHO]

A commercial or industrial (or residential too TBH) refrigeration mechanic would likely have the kit needed, though I'm less sure about using a tube bender with solid copper lengths.
Is your bender something like this? https://www.ebay.com.au/i/283202907741?chn=ps - This isn't an endorsement of that particular model, just ones like it haha
Good Luck!

 

[Kmpkt]

Yeah I bought one like that and a new selection of pipes. Will arrive mid to late week and will reattempt.

 

[Windfall]

Wow

top sekret

 

[teodoro]

any progress on the pipe bending?

 

[Kmpkt]

Pipes bent. Was going to tap the heatsink myself but lost my nerve (didn't want to ruin my only prototype tapping copper for the first time). Arranging to go to a machine shop to have things done properly.

@Kmpkt seeing those heat pipes reminded me of a forum thread you did a couple of years ago that tested stacking multiple heatpipes in a static(ish) aluminum heat sink. I think the outcome was something along the lines of heat pipes both having diminishing returns the more heatpipes you have and eventually are a negative as well as the quality of manufacturing can affect conductivity. ill see if i can find the thread.

@Tjo2012 there was this thread where dondan was testing heatsink samples from two different manufactures and one with 4 heatpipes from CoolJag was comparable to the one with 6 heatpipes from LianLi.

Nothing new from @Kmpkt ?

 

[Kmpkt]

Should have prototype any day. Just waiting for contact from the machine shop.

The hype is getting very, very real. Too bad I'm poor.

Same I too am quite eager to see Kmpkt's "Top Ƨekret" heatsink. This looks like a very cool project ...see what I did there? ...ok, I'm done.

Good luck @Kmpkt!
